What Is Sales Development? A 2026 Guide for B2B Leaders

Introduction

Your AEs say the calendar is thin. Your best closer spends Tuesday mornings building prospect lists, and someone on the leadership team has suggested hiring two sales development reps to fix it. That instinct is common, and it’s often right. You can build sales development with your own hires, run it through a partner with sales outsourcing, or combine the two, and each route changes what you control and what you pay for.

But the headcount is the easiest part to add. At Martal Group, we’ve run outbound for 2,000+ B2B brands since 2009, and the programs that last make two decisions before the first call goes out. They define what counts as an accepted meeting, and they size rep output to the AE capacity that will work it. Activity volume matters far less than either one. Martal Group is a B2B lead generation agency whose senior Sales Executives run Outbound Lead Generation, Appointment Setting, and Sales Outsourcing for B2B companies.

So start with the full operating view: what the function is, who does the work, and how the process runs. Then decide when to build it, how to measure and pay for it, and how to staff it while AI reshapes the job.

How this was built: we reviewed current sales development and AE benchmark research, B2B buyer surveys, and the questions sales leaders and reps raise in community threads, then read the findings against our own outbound execution. Why: to help you decide whether, when, and how to build sales development, with the tradeoffs stated plainly.

Sales Development: The Short Answer

1. Sales development is the B2B function that finds target accounts, starts conversations, qualifies interest, and books meetings for the account executives who close deals.
2. Sales development representatives (SDRs), sometimes titled business development representatives (BDRs), do the work, usually under a dedicated manager.
3. A working sales development process moves from targeting, through outreach and qualification, to a documented handoff and a feedback loop with the AEs.
4. Build it once outbound already works in a founder’s or AE’s hands and someone can manage the reps; before that point, a full-cycle AE is usually the better hire.
5. Judge sales development on AE-accepted opportunities and the pipeline they create, because booked meetings alone overstate what the function delivers.

The 2026 Shift in Sales Development

• Quota attainment for sales development reps hit a new low. The Bridge Group’s 10th SDR study, published in February 2025, found just 60% of SDRs at quota, while average ramp time fell to 3.0 months.
• Sales development headcount is shrinking at many software companies. Emergence Capital’s Beyond Benchmarks survey, reported by SaaStr in June 2025, showed 36% of B2B software companies cut SDR and BDR headcount over the prior year, and only 19% grew it.
• Buyers are tuning out generic outreach. A Gartner survey released in June 2025 found 61% of B2B buyers prefer a rep-free buying experience, and 73% actively avoid suppliers who send irrelevant outreach.
• AE time got more expensive. The Bridge Group’s 2026 AE study, published in June 2026, put average AE ramp at 6.2 months, the longest it has recorded, which raises the cost of every meeting an AE can’t work.
• The path from sales development to closing is narrow. Unify’s Path to AE research, released in August 2026, found 22.3% of a 180,000-person US SDR cohort reached an AE role, after a median of 12 active SDR months.

Sales Development Terms Worth Knowing

• Sales development representative (SDR) is the rep who researches accounts, runs outreach, qualifies interest, and books meetings for AEs.
• Business development representative (BDR) is a title many companies use for the same job, often weighted toward outbound prospecting.
• Account executive (AE) is the seller who runs discovery, demos, and negotiation, then closes the deal.
• Marketing qualified lead (MQL) is a prospect who responded to outreach and matches your ideal customer profile (ICP).
• Sales qualified lead (SQL) is an MQL who’s interested in a next step, such as more information or a meeting.
• Booked meeting is an SQL with a confirmed meeting on the calendar.
• Accepted opportunity is a held meeting that the AE agrees is real pipeline, which some benchmarks call a Stage 1 conversion.
• SDR-to-AE ratio is the number of AEs each SDR supports with meetings.

What Is Sales Development?

Sales development is the part of B2B sales that creates qualified conversations for your closers. Some teams call it pipeline generation, sales prospecting, or outbound business development. The team finds accounts that match your ideal customer profile, reaches the right people, qualifies interest based on authority and need, and books meetings that your AEs turn into deals. For most buyers, it’s the first live person they talk to at your company.

People search for it as “sales and development” or “sales business development,” and the loose wording reflects a loose understanding of the job. But in practice, the function has a narrow and measurable remit. It sits between marketing, which creates awareness and inbound interest, and closing, which turns qualified interest into revenue.

And it isn’t mandatory. If your AEs prospect, qualify, and close their own deals, you don’t have a sales development function yet. You have full-cycle sellers, and for a company with small deals or a short target list, that’s often the better setup.

How is sales development different from business development?

Business development looks for new markets, partners, and channels, while sales development works inside the market you’ve already chosen. A business development manager might spend a quarter negotiating a reseller agreement with a regional distributor. But a sales development rep spends the same quarter booking first meetings with operations directors at 300 target accounts.

The titles blur in small companies, where one person often does both jobs. That overlap usually holds until the person in the seat can’t keep a weekly outreach rhythm because partner meetings keep eating the calendar. So once that happens, the two roles need separate owners and separate targets.

Inbound vs. outbound sales development

Inbound sales development responds to people who’ve already raised a hand, and outbound starts conversations with accounts that haven’t. An inbound rep works demo requests, pricing-page form fills, and webinar attendees. And speed decides most outcomes here, so a rep who answers a demo request within the hour usually has the edge over one who replies the next morning.

Outbound reps work from a target list. They research each account, find a reason to reach out now, and run a cadence of calls, emails, and LinkedIn messages until they get a conversation or a clear no. If most of your pipeline already starts with a demo request, your inbound sales process carries the load, and outbound sales development becomes the lever for accounts that will never fill out a form.

Many companies run both, with separate reps for each. But mixing them in one seat tends to starve outbound, because an inbound lead always feels more urgent than the 40th call of the day.

Where does sales development sit in the org?

In most B2B companies, sales development reports to sales. The Bridge Group’s 2025 SDR study of 351 B2B companies found that 60% of SDR teams report to sales, 26% to marketing, and 10% to a CxO. And the same study found 82% of companies now align SDRs to AE territories, up from 56% in 2018.

The reporting line decides whose number your reps chase. Under marketing, they tend to be measured on how many marketing-qualified leads they convert. Under sales, AE acceptance becomes the scoreboard. Neither is wrong, but you’ll want to choose deliberately, since this line is one piece of your broader sales team structure, alongside territories and the ratio of reps to AEs.

What Does a Sales Development Representative Do?

A sales development representative researches target accounts, reaches buyers by phone, email, and LinkedIn, qualifies their interest, and books meetings for AEs. The job runs on volume and resets every month. At the median, an SDR logs 112 activities a day (44 calls, 41 emails, 19 LinkedIn touches, and 8 texts or other messages) to produce about 4.1 quality conversations, according to The Bridge Group’s 2025 benchmarks.

That ratio explains most of what the job feels like. Most dials end in voicemail, most emails get no reply, and the handful of live conversations each day have to count. So a typical day runs in blocks: account research first, a morning call block, follow-up emails and LinkedIn messages to the people just called, a second call block for later time zones, then CRM notes and handoff briefs for the AEs.

Reps in Reddit and community discussions often call it the hardest job in tech sales. The complaints are consistent, and they center on the rejection rate, a quota that resets every 30 days, and a promotion path that’s slower than the job posting suggested. But the upside comes up just as often. And few roles teach you to read a buyer, handle an objection live, and manage a pipeline as quickly as this one does.

You’ll get the most from your reps when you treat the role as a craft with its own skills, tools, and career path, rather than as an entry-level filter for future AEs. For the full breakdown of daily workflow, skills, and pay, see our guide to the sales development representative role.

Who Does Sales Development Work?

Sales development reps run the outreach, a dedicated manager coaches them and owns the team number, and AEs receive the meetings. Sales or revenue operations keeps routing, data, and reporting clean behind them. And each role has a failure mode that shows up in your pipeline, so it’s worth knowing what each one is supposed to own.

Sales development reps and business development reps

Many companies use both titles for the same job. When they split them, the business development title usually leans toward outbound prospecting into named accounts, and the sales development title leans toward inbound follow-up, though the convention flips from company to company. The difference between SDR vs BDR roles matters less than what the job description says the rep is measured on.

So write the job description around outputs. “Books 10 held meetings a month with VP-level buyers at manufacturers with 200 to 2,000 employees” tells a candidate far more than either title does.

The sales development manager

A sales development manager hires, coaches, and owns the team’s monthly number. Most companies title the role SDR manager, and The Bridge Group’s 2025 data shows a median of 6.4 SDRs per first-line leader, down from 8 in 2021 through 2023. That span runs from 3.6 reps at companies under $5 million in revenue to 8.1 at companies above $500 million, and median manager OTE reached $146,000.

The span matters because rep performance gets coached in weekly call reviews, and a quarterly business review moves far too slowly for that. A good manager listens to recorded calls every week and rewrites the opener when connect rates dip. And they defend the team when AEs reject meetings without a reason. But if that person is also carrying their own closing quota, the coaching slips to last place on the calendar every week.

The account executive on the receiving end

AEs run discovery, demos, and negotiation, and they’re the reason sales development exists. The same 2025 study puts the ratio at one SDR for every 2.4 AEs, a figure that’s held steady since 2018. Some companies title the closing role sales executive, and the job is the same either way: take the meeting, qualify it further, and work it to a decision.

And AE time is getting more expensive. The Bridge Group’s 2026 AE study found average AE ramp has reached 6.2 months, the longest it has recorded, and only 48% of AEs hit quota. Every meeting a rep books lands on that constrained calendar. If your AEs are already full, extra meetings turn into rushed discovery calls and frustrated prospects.

Account managers after the close

Account managers own the customer after the first deal: renewals, expansion, and keeping the relationship healthy. Sales development rarely touches them directly. But the line is moving. The same 2026 AE research found 38% of AEs now hold sole or blended ownership of renewal and expansion, nearly double the 2024 share, which means your closers have less time for new meetings than they did two years ago.

If you’re planning rep capacity, check how much of each AE’s week already goes to existing accounts. That number tells you more about how many meetings they can absorb than headcount does.

Getting the titles straight

Titles drift as companies grow. An “account executive” at a 20-person startup may prospect, demo, close, and onboard, while the same title at a 2,000-person company means a closer who never cold-calls. So define a clear set of sales titles with one owner per stage of the funnel. That stops reps from doing two jobs badly, and it lets you compare your numbers with external benchmarks.

What’s the career path in sales development?

Most sales development reps aim for an AE role, but the path also leads to senior rep, team lead, account manager, or sales development manager. Unify’s 2026 research puts the median time to an AE role at 12 active SDR months for the reps who make the move, and most of a recent cohort hadn’t moved yet. So the path takes longer than many job postings imply. Publishing the steps and the criteria for each one is among the cheapest retention moves you can make.

The Sales Development Process, Stage by Stage

The sales development process runs in six stages, from defining who you’re after to feeding results back into targeting and messaging. Each stage needs an owner and a written definition of done. And when teams skip one, it almost always shows up later as low AE acceptance or a wave of no-shows.

1. Define your target buyer and what counts as an accepted meeting

Start by writing down two things: the accounts and people you want, and the meeting your AEs will accept. A useful definition is specific enough to argue with. For example, an accepted meeting might be a VP of Finance at a manufacturer with 200 to 1,000 employees who has described a forecasting problem and confirmed a 30-minute discovery call.

Then get the AEs to sign off on that definition before outreach starts. There’s a real tradeoff here. Set the bar too high and your reps book two meetings a month while AE calendars sit empty. But set it too low and your AEs stop trusting anything the sales development team books, which is harder to repair than a slow month.

2. Build and maintain the target list

The list decides the ceiling on everything after it. A strong list starts from your ideal customer profile, removes accounts that don’t fit your criteria, ranks the rest by fit and buying signal, and adds verified email addresses, direct dials, and LinkedIn profiles for the right people. Then it stays current while the campaign runs, because job changes and funding rounds make a static list stale within weeks.

We call this list engineering. Every account clears your criteria before a rep touches it, and the list keeps improving during the campaign as role changes and newly qualifying accounts get added.

3. Run the outreach cadence

Outreach works best as a coordinated, omnichannel sequence across calls, email, and LinkedIn, spread over two to four weeks. A common SDR outreach cadence alternates channels so each touch builds on the last: an email that references a trigger event, a call two days later that mentions the email, then a LinkedIn connection request.

And the channel mix changes results. In The Bridge Group’s 2025 data, phone-centric SDR teams averaged 56 dials and 4.6 quality conversations a day. Email-centric teams averaged 28 dials and 3.4 quality conversations. Some buyers simply don’t answer the phone, though, so test the mix against your own buyers before you copy anyone’s ratio.

4. Qualify on authority and need

Qualification answers two questions: does this person have a say in the decision, and do they have a problem you solve right now? Budget and timing matter later, and AEs usually uncover them better in discovery. And pushing reps to confirm budget on a first call mostly teaches prospects to stop answering.

Use one shared language for the funnel. A prospect is someone you’ve contacted. An MQL responded and fits your ICP. An SQL wants a next step, and a booked meeting is an SQL with a confirmed time on the calendar. And keeping SQLs and booked meetings separate in your reports shows you where interest stalls before it reaches a calendar.

5. Book the meeting and hand it off

The handoff is where most value leaks out. Strong B2B appointment setting confirms the meeting by email the day before, sends the calendar invite from the AE’s calendar, and passes a short brief. The brief covers why the prospect took the meeting, the problem in their own words, who else is involved, and any timing they mentioned.

Here’s what that discipline looks like over time. For a California IT company selling data management technology, our team generated 119 MQLs over five months. Of those, 35 became SQLs and 21 became booked meetings. Tracking SQLs and booked meetings separately showed the client exactly where follow-up time paid off, and the CEO singled out the plain, genuine tone of the messaging as the reason buyers engaged.

6. Close the loop with the AEs

The last stage feeds results back into stage one. Ask AEs to mark every held meeting as accepted or rejected within 48 hours, with a one-line reason. Then review those reasons weekly with the sales development team and update the target profile, the list, and the messaging when a pattern shows up.

A short, fixed agenda keeps that review honest. Many leaders keep a standing list, such as 10 questions to ask your sales team, covering which meetings went nowhere, which objections came up twice, and which accounts surprised the AEs. And without this loop, reps keep booking meetings your AEs quietly ignore, and neither side knows why the numbers drift.

What tools does a sales development team need?

A sales development team runs on five tool categories, and each one supports a stage of the process. You don’t need the most expensive option in every category. You need each one connected to the CRM so activity, meetings, and outcomes land in one place.

• CRM: the CRM holds every account, contact, call, and meeting, and it’s where reps write the handoff brief your AEs read.
• Sales engagement platform: this runs the outreach cadence, queues each day’s calls and emails, and records what happened on every touch.
• Contact data and enrichment: a data source supplies verified email addresses and direct dials, and it flags job changes so the list stays current.
• LinkedIn: reps use it to find the right people at each account, watch for role changes, and send connection requests and messages.
• AI research assistants: these summarize an account’s recent news, draft first-pass emails from a trigger event, and log call notes, which frees reps for live conversations.

Add tools after the process works. Adding a sequencing tool to an unqualified list mostly increases the number of wrong contacts you reach.

Is Your Company Ready for Sales Development? A Five-Rung Readiness Ladder

Sales development pays off when it amplifies a sales motion that already works. The ladder has five rungs. So find the one that describes your company today, and move up only when that rung’s exit condition is true.

The thresholds are working heuristics from our outbound execution. Adjust them for your deal size and sales cycle, but keep the order.

Rung 1: Founder-led selling

• You’re here if: a founder runs every first call, and most closed deals came through the founder’s network or warm introductions.
• Move up when: you’ve closed customers who had never heard of you, and you can explain in two sentences why they bought.
• Cost of moving early: a new rep inherits a pitch that lives in the founder’s head and gets measured on results nobody else could produce yet.

Rung 2: Full-cycle AEs

• You’re here if: one to three AEs prospect, run demos, and close their own deals.
• Move up when: your AEs book outbound meetings that convert, and their calendars have become the constraint on growth.
• Cost of moving early: your first rep runs untested messaging, books meetings nobody trusts, and leaves within the year.

This is the rung founders most often skip. Operators in founder communities repeat one piece of advice more than any other. Hire junior reps once a working process exists for them to run, and keep the process design with someone who has already sold the product.

Rung 3: Your first sales development reps

• You’re here if: you’ve hired one or two reps to feed AEs who were previously prospecting for themselves.
• Move up when: your reps hit their accepted-opportunity target for two straight quarters and AEs accept most of what they book.
• Cost of moving early: you scale a model you haven’t proven, and every new hire inherits the same unresolved problems.

Many founders advise hiring two reps at once. If one succeeds and one doesn’t, you’ve likely got a hiring problem. But if both struggle, the problem is probably the market, the message, or the list.

Rung 4: A managed sales development team

• You’re here if: you have four or more reps and a dedicated manager who doesn’t carry a closing quota.
• Move up when: you need to cover new segments, products, or markets faster than you can hire and ramp reps.
• Cost of moving early: your manager splits attention across segments before the core motion is stable.

At this rung, structured SDR programs start paying off. A written ramp plan, call-review rhythm, and promotion criteria turn a group of reps into a system that survives turnover.

Rung 5: Specialized or extended sales development

• You’re here if: you split reps by segment (inbound and outbound, or enterprise and mid-market) or add outside capacity for new markets.
• Move up when: this is the top rung, so the work becomes keeping each pod’s targets tied to AE capacity.
• Cost of moving early: specialization adds handoffs, and each one needs its own brief and owner or context gets lost between pods.

At this point, the question shifts from whether to build to how to staff each piece, which is where the in-house, outsourced, and fractional models come in.

When full-cycle AEs beat sales development

There’s a strong argument against building sales development at all, and in some businesses it wins. If your average deal is small, a dedicated rep’s fully loaded cost can exceed the pipeline value the role creates. Or if most of your buyers come to you through inbound demand, your AEs may be able to handle it without a separate team. And if your total market is 150 named accounts, a dedicated AE who owns each relationship from the first touch often outperforms a relay between two sellers.

Deal size drives most of the economics. Pipeline per rep has been rising mainly because deals got larger, so the role pays least where deals are smallest.

Where the case for sales development still holds is the point at which AE time becomes the scarcest resource you have. And once your closers spend hours each week prospecting while qualified deals wait, splitting the work usually pays. But until then, another full-cycle AE is often the better hire.

How Should You Measure Sales Development?

Measure sales development on three layers. Accepted opportunities and pipeline are the outcome, held meetings are the bridge, and activity is the early warning. Pay and promote on the first layer, coach on the second, and watch the third weekly. The full set of SDR KPIs goes deeper, but these three layers keep the team pointed at revenue.

What does activity tell you?

Activity tells you whether the engine is running. Track calls, emails, and conversations per rep week over week. And if a rep’s activity drops by a third for two weeks, you’ll see it here before it shows up in meetings.

But activity is easy to inflate and easy to game. A rep can send 60 templated emails in an hour and hit any activity target you set. So keep it on the coaching dashboard and out of the comp plan.

Why do held and accepted meetings matter more than booked ones?

A booked meeting only counts once it’s held and the AE agrees it’s real. The Bridge Group’s 2025 study found the global median monthly quota is 10 held first meetings, down 40% since 2018. The median quota for meetings that convert into accepted pipeline is 6, down 43% over the same period. Fewer, better meetings are already the norm at companies that measure carefully.

No-shows are the gap between booked and held, and they come up constantly in rep and manager threads. A confirmation email the day before, a calendar invite from the AE’s own calendar, and a short agenda in the invite all help. But if no-shows keep climbing, look at qualification first, since prospects who weren’t interested rarely turn up.

Does pipeline per rep show whether it pays?

Yes, as long as you know what’s driving it. Median raw pipeline per SDR reached $3.78 million in that same study, up from $2.83 million in 2022, and half of respondents reported between $1.9 million and $6.4 million. The report attributes the increase to larger deal sizes rather than more meetings. So compare yourself against your own history before you compare against the median.

How do you track which meetings your reps booked?

Users in Reddit and community discussions often ask how to separate meetings reps booked from meetings prospects booked themselves through the website. One HubSpot community thread lands on a practical fix. Give reps their own booking link or meeting type, separate from the one on your site, so every meeting carries its source automatically.

The same principle applies in any CRM. Tag the source at the moment of booking. Or you’ll end up rebuilding attribution at quarter-end, which turns into an argument about who deserves credit.

What’s the catch with paying on accepted opportunities?

Paying reps on accepted opportunities puts part of their income in an AE’s hands. If AEs reject meetings without explanation, or sit on them for a week, your reps will feel cheated, and they’ll be right. So protect the model with a 48-hour acceptance window, a written reason for every rejection, and a manager who reviews disputed meetings weekly. And new reps in their first three months may need a guaranteed portion of variable pay while they learn what an acceptable meeting looks like.

What Does Sales Development Cost?

The median sales development rep earns $80,000 in on-target earnings, split roughly $55,000 base and $25,000 variable, according to The Bridge Group’s 2025 SDR benchmarks. That figure hasn’t moved since 2022. But your real cost is higher, because each rep also carries ramp time, a share of a manager’s salary, turnover, and tooling. Pay varies by market and seniority, and our SDR salary breakdown covers the ranges in more detail.

Which costs don’t show up on the offer letter?

Four costs sit outside the salary line, and together they often exceed it.

• Ramp: average ramp time for a new SDR is 3.0 months, the shortest since 2010, so each new hire spends roughly a quarter of year one below full output.
• Turnover: median annual attrition was 40% in 2024, and average tenure is 1.9 years, so you should budget to backfill at least one seat for every two or three SDRs you hire.
• Management: the median OTE for an SDR manager is $146,000, and with 6.4 reps per manager, each rep carries about $22,800 of management cost.
• Tools and data: every rep needs a CRM seat, a dialer, email sequencing, and contact data, and those costs vary too widely to benchmark well.

The management figure is our arithmetic on those medians. Your number will shift with team size, but the point holds. A team of two reps still needs someone to coach them, and that person’s time costs real money whether or not it shows up in the sales development budget.

A worked example: two in-house reps in year one

Say you hire two SDRs at the median OTE and give them a manager who also oversees four other reps. Here’s a rough first-year view, before tools and recruiting fees.

1. Two SDRs at $80,000 OTE come to $160,000.
2. Their share of a $146,000 manager, at one-third of the manager’s six reps, is about $48,700.
3. Total year-one people cost is about $208,700.
4. With three months of ramp each, you get roughly 18 productive SDR-months, which works out to about $11,600 per productive month.

At the median quota of 10 held meetings a month, that’s about $1,160 per held meeting before you count tools, recruiting, or a mid-year departure. But whether that’s cheap depends entirely on your deal size and on how many of those meetings your AEs accept.

The tradeoff cuts the other way too. Pushing the cost per meeting down by hiring the cheapest reps you can find usually backfires. A rep who books meetings AEs reject costs you the salary plus the AE hours spent on calls that were never going anywhere.

In-House, Outsourced, Fractional, or Hybrid: How Should You Staff Sales Development?

You can staff sales development four ways. You can hire your own team, outsource it to a partner, buy fractional capacity, or run a hybrid of in-house and outside reps. The right choice depends on what you need to own, how fast you need pipeline, and whether you’re building future AEs. Each model is assessed on the same four points so you can compare them directly.

In-house team

• Best for: companies with a proven motion, a manager in place, and a plan to promote reps into AE roles.
• What you control: every hire, every message, the tooling, and the culture your reps work in.
• What you carry: recruiting, a three-month ramp per hire, high annual turnover, and the manager’s time.
• Watch for: a team that’s sized to your hiring plan rather than to your AEs’ capacity to work the meetings.

If you go this route, plan to hire a sales team in waves rather than all at once, so each cohort learns from the last. A written sales competency model gives your interviewers the same scorecard for coachability, written communication, and resilience after rejection.

For sourcing, our guides on the best place to find SDR talent and on B2B sales recruitment cover the channels that tend to work. And if you’re hiring reps in several countries, your global hiring strategy needs to settle employment rules, time zones, and pay bands before the first offer goes out.

Outsourced sales development

• Best for: companies that need pipeline within weeks, want to test a new segment or market, or can’t hire and manage reps fast enough.
• What you control: the ideal customer profile, the accepted-meeting definition, and approval of the messaging, with weekly reporting on what’s working.
• What you carry: a monthly fee, the work of briefing the partner well, and the need to pull market feedback into your own team.
• Watch for: partners who report prospects contacted instead of sales-qualified leads and booked meetings, or who can’t explain how they build the target list.

The case for outsourcing sales development rests on speed and risk. With Martal, you can run at 61% to 72% lower cost than an in-house team delivering the same qualified leads, and ramp up three times faster than in-house SDR onboarding allows. From signature, onboarding typically runs 7 to 10 business days, with campaigns live by day 3 after your start date, as long as your team reviews the ideal customer profile and messaging on schedule. So when you’re comparing outsourced SDR companies, ask each one what a weekly report contains and who writes the messaging. Some providers sell outsourced BDR services as a block of rep hours, while others commit to qualified meetings, and the difference shapes everything that follows.

We structure this in two tiers. Tier 1 is Outbound Lead Generation and Appointment Setting, delivered as one engagement: engineered lead lists, omnichannel outreach across calls, email, and LinkedIn, qualification, and meetings booked on your calendar. It’s a complete engagement on its own, and most clients start there. Tier 2 is Sales Outsourcing, which is Tier 1 plus the close. Our team carries qualified opportunities from discovery and proposal through negotiation, close, and onboarding.

Fractional sales development

• Best for: companies that need dedicated sales development ownership without the cost of a full in-house team.
• What you control: the target market, the definition of an accepted meeting, and the weekly priorities.
• What you carry: a smaller monthly commitment and a clear brief, since a small team moves fast only when the targeting is sharp.
• Watch for: setups where one rep is spread across several clients with no single owner for your account.

A fractional SDR model buys capacity in a different shape. At Martal, a fractional team is typically two senior Sales Executives and one account manager who own your campaign end to end, from prospecting through booking, with no internal handoffs. “Fractional” describes how you buy the capacity. The work itself has one owner throughout.

Hybrid sales development

• Best for: companies with an in-house team that need coverage for a new segment, product, or region without pausing the core motion.
• What you control: your core accounts and team, plus the targets you set for the outside pod.
• What you carry: two reporting streams to reconcile and a shared definition of an accepted meeting that both sides follow.
• Watch for: the two teams contacting the same accounts, which annoys prospects and muddies attribution.

Which model should you pick?

Pick in-house when you’re building a bench of future AEs and have a manager ready. Pick outsourced or fractional when speed, a market test, or management bandwidth is the constraint. And hybrid fits teams that already run well in one segment and want to open a second without diverting their best reps.

Each model has a cost the others avoid. Outsourcing can cost you institutional learning if call notes and objections never reach your team, so ask for that feedback weekly. But building in-house costs you time and turnover. Write both costs into the decision before you commit, and you’ll pick a model you can live with.

A sample sales development rep job description

If you’re hiring in-house, write the job description around measured outputs, so candidates know what success looks like before they apply. This example targets finance buyers at mid-market manufacturers, so swap in your own target buyers, numbers, and pay band.

Role summary: you’ll start conversations with VP- and director-level finance buyers at manufacturers with 200 to 2,000 employees, qualify their interest based on authority and need, and book discovery meetings for our account executives.

• Research target accounts and find the right buyer and a reason to reach out now.
• Run omnichannel outreach across phone, email, and LinkedIn using the team’s cadence.
• Qualify interest, then book meetings on AE calendars with a written handoff brief.
• Log every touch and outcome in the CRM.

Measured outputs:

• 10 held first meetings a month at full productivity, with at least 6 accepted by an AE as pipeline, in line with the median quotas.
• A three-month ramp to full quota, with weekly call reviews along the way.

Requirements:

• One to two years in a customer-facing role, such as sales, customer success, or recruiting.
• Short, specific written communication and comfort on the phone.
• Coachability, shown by how you respond to feedback during a mock call.

Compensation: $80,000 OTE, split roughly $55,000 base and $25,000 variable, in line with the median, with variable pay tied to held, accepted meetings.

A pay band below the median will shrink your candidate pool. And measured outputs that don’t match your AEs’ capacity will set the new hire up to miss, so check both against your own numbers before you post.

How Is AI Changing Sales Development?

AI is taking over the research, drafting, and data cleanup that used to fill a rep’s morning, and sales development teams are getting smaller and more selective as a result. But the live conversation, the judgment about who’s worth a call, and the handoff to an AE still sit with people. The bigger shift is on the buyer side, where cheaper outreach has made inboxes noisier and buyers more willing to ignore anything generic.

What the headcount data shows

The function is shrinking, and most companies are still keeping it. Emergence Capital surveyed 560+ B2B software companies backed by venture capital for its Beyond Benchmarks report, and as reported by SaaStr, 36% decreased SDR and BDR headcount over the prior year. That was the highest share of any sales role. But another 44% kept their teams the same size, and 19% grew them.

AI-only programs are still rare. The Bridge Group’s 2025 study was the first edition in which “AI SDRs” appeared as a distinct category, and they accounted for just 1% of respondents. In community threads, reps and managers report a familiar pattern: companies that swapped people for automated sequences saw prospects complain about spam, and several moved back to a hybrid model within months.

Why buyers are raising the bar

Cheaper outreach has made buyers pickier. Gartner’s 2025 survey of 632 B2B buyers found 61% prefer a rep-free buying experience, and 73% actively avoid suppliers who send irrelevant outreach. The same research found buyers still want seller input on tasks that need context, such as working out whether a product fits their company.

Which means raw volume has lost most of its value as a strategy. If AI lets your team send three times as many emails to buyers who avoid irrelevant outreach, the main result is more accounts that filter you out. So precise targeting and a clear reason to reach out now matter more than they did five years ago.

What AI handles well, and what still needs a person

AI handles the parts of the job that follow a pattern. It summarizes an account’s recent news, drafts a first-pass email from a trigger event, logs call notes, and flags contacts who changed jobs. And that frees rep time for the calls and replies that actually move a deal.

People still own the moments that need judgment. A prospect says “we tried something like this last year and it failed,” and the rep has to decide in real time whether to probe or back off. A reply comes in from the wrong person, and the rep has to work out who actually owns the problem. And those calls decide whether a meeting happens, and they’re where a senior sales executive earns their keep.

What should you change in your program?

Start by moving your metrics toward quality. Track accepted opportunities and the reasons AEs reject meetings, since those numbers show whether AI-assisted outreach is landing or just adding noise. Then point your reps at signals, like a new VP of Sales, a funding round, or a job posting for the role your product replaces, instead of at static lists.

The early data on AI adoption is encouraging, but read it carefully. In The Bridge Group’s 2026 AE study, companies in the highest AI-engagement group reported 57% of AEs at quota, compared with 39% in the lowest. The report itself describes this as observational. Companies that invest heavily in AI may also differ in hiring, management, and market, so treat the gap as a reason to run your own test before you expect AI to lift your numbers.

How Does Sales Development Change Across Sales Motions?

The function stays the same across sales motions, but its shape changes with how you sell. Who the rep contacts, what they qualify for, and where the meeting goes all depend on whether you sell directly, through partners, remotely, or into technical buyers.

Inside and virtual sales

Most modern sales development lives inside an inside sales model, where reps sell by phone, email, and video rather than in person. If you’re asking what is inside sales and how it relates, the short answer is that sales development reps are usually the first stage of an inside sales team. And fully remote teams add one more layer. In virtual sales, the rep’s handoff note matters even more, because the AE can’t lean over a desk to ask what the prospect said.

Direct sales

In direct sales, your own team sells to the end customer, and sales development follows the standard six-stage process. The rep books meetings with buyers at target accounts, and an AE works each one to a decision.

Channel sales and sales partners

In channel sales, the rep’s buyer may not be the end customer at all. Some teams point sales development at recruiting resellers, distributors, or a sales partner, then help those partners book meetings in their own territories. So the qualification questions change accordingly. You’re asking whether a partner has the customer base and the sales capacity to sell your product, so treat partner recruitment as its own campaign with its own accepted-meeting definition.

Technical sales

In technical sales, the first meeting often needs a sales engineer or solutions consultant in the room. Reps here need enough product knowledge to qualify the technical fit, such as which systems a prospect runs or whether they meet an integration requirement. But they also need to know when to stop and hand the question to an expert. Getting that wrong in either direction costs you. A rep who oversells the product sets up a bad demo, and one who can’t answer a basic question loses the meeting.

Why Do Sales Development Teams Stall?

Picture a software company that hired four sales development reps last spring. By fall, activity is high, meetings booked look healthy, and AEs say half of them are a waste of time. And two reps have quit, while the pipeline stays flat. Most stalls like this trace back to incentives, management, or AE capacity, and rep effort is rarely the cause.

You pay per booked meeting

Paying reps for every booked meeting is the most common cause of junk meetings, and community threads are full of AEs complaining about it. Reps are rational. If a meeting with an intern who agreed to “learn more” pays the same as one with a VP who has a budget, you’ll get plenty of interns. Move variable pay to held, accepted meetings, and the problem usually shrinks once a full quarter runs under the new plan.

You hired juniors to write the playbook

A new rep fresh out of college can run a playbook, but writing one takes someone who’s already seen what works. But when the first hires are expected to define the target market, write the messaging, and choose the tools, they usually fail, and leadership concludes that outbound doesn’t work for the company. The motion was never tested, so that conclusion is premature.

Your reps have no manager or no path

Reps without a dedicated manager drift, and reps without a visible path leave. The Bridge Group’s 2025 data shows promotions made up 16% of SDR attrition in 2024, less than half the 34% share in 2020. Unify’s 2026 Path to AE research tells a similar story from the rep’s side, with only 22.3% of a recent SDR cohort reaching an AE role.

You can’t promote everyone, but you can make the path explicit. When you map sales titles to business functions, each step up (senior rep, team lead, AE, or account manager) comes with a clear definition and a clear set of criteria. Reps who can see what the next role requires are more likely to stay and work toward it.

You booked more meetings than your AEs can work

This stall is easy to miss because the sales development dashboard looks great. The team hits its number, the AEs’ calendars overflow, and discovery calls get rushed or rescheduled until prospects lose interest. And because new AEs take months to ramp, you can’t fix that gap by hiring closers quickly. So set rep targets from AE capacity, and grow both together.

Building Sales Development Your AEs Will Trust

Sales development works when it feeds closers meetings they’re glad to take. That comes down to a few decisions you make early: a written definition of an accepted meeting, targets sized to AE capacity, and a manager who coaches every week. So get those right, and the staffing model becomes a question of speed and control.

If you’re still on the first or second rung of the ladder, a strong full-cycle AE may serve you better than a sales development rep this year. If your AEs are spending their mornings prospecting while qualified deals wait, it’s time to split the work, either with your own team or with a partner who can start sooner.
