Introduction
In the fast-paced B2B landscape of 2026, partnering with an outsourcing agency can be a game-changer for sales and marketing leaders. An outsourcing agency (or “outsource agency”) is an external firm you hire to handle specific business functions – in this case, driving B2B sales pipeline and revenue on your behalf. Instead of building everything in-house, you tap into a ready-made team with specialized skills, tools, and processes.
What does that mean in practice? It means an outsourcing partner can manage everything from outbound prospecting and lead generation to booking meetings and even closing deals for your company (1). The right sales agency brings industry expertise, proven outreach strategies, and scalability that internal teams often struggle to match.
Why is choosing the rightoutsourcing agency so critical in 2026? Simply put, the stakes for B2B growth are higher than ever. Buying cycles are longer and more complex, while go-to-market speeds are accelerating. Companies that thrive are leveraging external partners to gain an edge in efficiency and reach. In fact, 73% of fast-growing companies outsource at least one sales function to scale faster (3). And it’s not just about speed – it’s about ROI. Our data shows outsourcing with expert execution and economies of scale delivers cost savings of up to 65% (4). With tighter budgets and higher growth targets, many B2B firms plan to use a hybrid model (combining in-house efforts with outsourcing) – over 46% of organizations expect to operate with such a mix by 2026 (6). However, outcomes vary wildly between providers. Choose well, and you get a strategic partner who fills your pipeline with qualified leads at a lower cost; choose poorly, and you risk wasted spend, brand damage, or missed opportunities. This guide will walk you through exactly how to evaluate outsourcing agencies and pick the right one for your B2B needs.
Below, we’ll cover what sales and marketing outsourcing agencies do, key services to look for in 2026, signs that it’s time to consider outsourcing for your sales team, and the criteria that matter most when comparing agencies. We’ll also provide a list of some of the best B2B outsourcing agencies of 2026, what makes each stand out, and address common outsourcing questions. Let’s dive in.
What Is an Outsourcing Agency?

At its core, an outsourcing agency is a company that you contract to handle a business function or process that you would otherwise manage internally. In a B2B sales context, an outsourcing agency (often called a sales outsourcing firm or outsourced SDR agency) acts as an extension of your sales team. You delegate sales tasks – such as finding leads, contacting prospects, nurturing opportunities, and even closing deals – to this external partner (1). Essentially, the agency’s sales professionals become your reps, working to generate revenue under your direction but on their payroll.
Outsourcing agencies differ from consultants or software tools in that they execute the sales process hands-on, rather than just advising or providing data. They recruit and train sales development representatives (SDRs), account executives, or entire teams to carry out multi-channel outreach and sales activities for your company. A good outsourcing agency will integrate with your organization’s strategy and brand voice, often representing themselves as part of “your company” to prospects. You gain the benefit of experienced talent and established processes without the overhead of hiring full-time staff.
Key characteristics of outsourcing agencies:
- Third-Party Teams: They have their own trained staff (SDRs, BDRs, sales reps, etc.) who perform the work for you, usually remotely. You’re essentially renting a sales team.
- Defined Services: Outsourcing agencies offer packaged services such as lead generation campaigns, appointment setting, full-cycle sales closing, customer outreach, and more. You choose which parts of the sales process to outsource.
- Service-Level Agreements (SLAs): The partnership is governed by a contract specifying deliverables – e.g. number of appointments per month, lead quality criteria, reporting cadence, etc., ensuring accountability for results.
- Monthly or Outcome-Based Fees: Rather than salaries, you pay the agency either a monthly retainer or per-result fees (like per meeting or commission on closed deals, depending on the model). This converts fixed costs into variable costs aligned with performance.
In summary, an outsourcing agency is your sales team on demand. By leveraging one, B2B companies gain specialized expertise and capacity quickly without the long ramp-up of hiring internally (2). The right partner will seamlessly represent your brand, use modern techniques to engage your target buyers, and deliver a consistent pipeline of opportunities for your in-house team to close.
Key Outsourcing Company Services in 2026

Outsourced SDR companies in 2026 offer a wide array of “sales-as-a-service” solutions. While traditional telemarketing shops focused on just cold calling, today’s top outsourcing companies provide comprehensive, tech-enabled services that cover the full sales development cycle. Here are some of the key outsourcing company services you should expect (and seek out) in 2026:
- Outbound Lead Generation & Prospecting: Building targeted lead lists of prospects and reaching out via cold email, cold calls, and social touches to generate interest. This often includes researching ideal accounts and contacts, crafting personalized messaging, and running multi-touch outbound sequences to create a steady flow of qualified leads (2). Modern agencies use data intelligence and even intent signals to refine targeting – for example, leveraging technologies to identify which companies are actively looking for your solutions. (In fact, over 70% of sales teams now use AI/automation to qualify sales leads and personalize outreach (7), so expect your agency to use these tools as well.)
- Appointment Setting Services (Outsourced SDRs): Many B2B firms outsource lead generation and the Sales Development Representative (SDR) function. In this model, the agency’s reps handle initial conversations with prospects – via email, LinkedIn, and phone – and nurture them until they’re sales-qualified. They then book meetings or demos for your internal sales executives. This service ensures your closers spend time only on vetted prospects who have shown interest, boosting win rates. It’s common to have an outsourced SDR team schedule dozens of meetings per month for a client, effectively acting as your external pipeline engine.
- Inside Sales / Full Sales Team (“Sales as a Service”): Beyond top-of-funnel lead gen, some outsourcing agencies provide full-cycle sales reps who can carry opportunities further down the funnel – conducting product demos, handling follow-ups, and even closing deals. This is often called fractional sales teams or sales outsourcing. For example, outsourcing inside sales providers can help manage SMB accounts or transactional sales entirely. There are providers (including Martal Group) that offer end-to-end sales outsourcing, where dedicated account executives represent your company from first contact all the way to signing the contract (2). This can be ideal if you lack an in-house sales team or want to rapidly enter a new market without hiring permanent staff.
- Cold Calling Services & Telemarketing Campaigns: Despite rumors of its demise, cold calling is alive and well in 2026 as part of a balanced outbound strategy. Many outsourcing agencies have call center teams or on-demand outbound callers to reach prospects by phone. In B2B, call outreach is often used in conjunction with email and LinkedIn (omnichannel) to improve contact rates. Look for agencies that provide call recording and analytics, so you get transparency into call quality. The best will use modern VoIP tech and local caller IDs to improve pickup rates, and they’ll ensure compliance with regulations. (Fun fact: one industry report found that 78% of decision makers have taken a meeting or event due to an email or cold call – reinforcing that skilled outreach does work (8).)
- LinkedIn Lead Generation: Given LinkedIn is the #1 network for B2B professionals, many outsourcing companies offer specialized LinkedIn outreach services. This involves optimizing your profile, sending connection requests to targeted prospects, and messaging them to spark conversations. In 2026, LinkedIn outreach is often augmented with automation tools for scale but combined with human personalization to avoid the “spam” trap. Agencies may run LinkedIn campaigns that connect you with hundreds of qualified buyers monthly – turning new connections into sales conversations on your behalf. This service is especially useful for reaching decision-makers who ignore cold emails but might respond on a social platform.
- Lead Nurturing & Follow-Up: Not all leads will be ready to talk when first contacted. Outsourcing agencies can handle the tedious but crucial work of nurturing cold or early-stage leads. This might include email drip campaigns, LinkedIn content engagement, or periodic check-in calls to keep your company top-of-mind. They ensure no lead falls through the cracks, warming them up until a prospect hits a trigger (like new funding or a project initiative) that makes them sales-ready (2). By outsourcing this, you maintain momentum with prospects over the long sales cycles typical in B2B.
- Pipeline Management & CRM Administration: Some providers will even manage parts of your CRM and pipeline hygiene. They can update contact records, log activities, and move deals through stages so your data stays clean. While this is a more supplementary service, it’s valuable if your team is stretched thin on sales ops capacity. Moreover, reporting is a key part of outsourcing engagements – agencies will typically provide weekly or monthly performance reports (and some offer real-time dashboard access) so you can track results closely.
- Sales Training and Sales Enablement: A newer offering in 2026 is sales training-as-a-service. A few outsourcing agencies (like Martal Group) have formal training programs to upskill your internal team or ramp up dedicated outsourced reps quickly. For instance, Martal’s Academy provides B2B lead generation training to teach reps modern outbound techniques and omnichannel strategies. While not every demand generation agency offers this, it’s a bonus if they can both do the work and teach best practices to your staff, creating a lasting impact beyond the contract period.
- AI-Powered Sales Engagement Platforms: Finally, a key 2026 development is agencies providing their own proprietary software platforms. Some top firms have built AI-driven outreach platforms that automate and optimize campaigns. For example, Martal’s AI SDR Platform uses an algorithm (GTM-1 Omni) to analyze thousands of intent signals and craft optimized messaging in real-time. As a client, you benefit from these cutting-edge tools without having to buy them yourself. When evaluating agencies, ask about their tech stack – the integration of AI and automation can dramatically improve lead quality and speed of engagement (companies embracing AI in sales see up to 50% higher productivity in their sales teams (7)).
In summary, outsourcing agencies today are one-stop shops for sales development. The key services span every stage of the sales funnel: top-of-funnel research and outreach, mid-funnel appointment setting and nurturing, and even bottom-of-funnel closing and account management. In 2026, leading agencies differentiate by delivering these services in an omnichannel, data-driven way – combining email, phone, LinkedIn, and sometimes content marketing – and by leveraging AI and automation to work smarter. When choosing a partner, ensure their service menu aligns with your needs. If you only need more sales meetings, a pure appointment-setting service may suffice. But if you aim to outsource entire markets or product lines, look for a provider with full-cycle capabilities. And always verify the agency has experience executing the specific services you require at the scale and quality you expect.
When to Consider an Outsourcing Agency for B2B Sales
Using outsourced SDRs, companies can reach full productivity 3x faster than with in-house teams.
Reference Source: Martal Group
How do you know if it’s the right time to bring in an outsourcing agency for your sales efforts? For many organizations, outsourcing is triggered by specific challenges or growth goals. Here are some common scenarios where outsourcing agencies can add major value for B2B sales teams:
- Limited In-House Capacity or Expertise: Perhaps your marketing team is generating more leads than your sales reps can follow up on, or your small sales team lacks experience in a certain area (like handling inside sales or enterprise outreach). If your internal team is stretched thin or missing key skills, an outsourcing agency provides ready-made experts to bridge the gap (1). For example, if your team has never prospected into the Fortune 500 but that’s a goal, partnering with an agency that specializes in enterprise outreach can accelerate progress.
- Aggressive Growth or Scaling Goals: When you need to ramp up sales quickly, outsourcing is often the fastest path. Hiring and onboarding new in-house reps can take months, whereas an agency can deploy a team in a matter of weeks (9). Companies just after funding rounds or those launching new products often outsource to scale pipeline now rather than waiting to build a full team. By outsourcing, businesses can expand their sales reach nearly instantly without the usual delays of recruiting and training staff (1).
- Entering New Markets or Verticals: Expanding to a new geographic region or industry vertical is a prime reason to use an outsourcing agency. If your company is eyeing, say, the European market but has no local sales presence, you can contract an agency with on-the-ground teams in Europe to test the waters. They bring local language skills, time-zone coverage, and market knowledge. Similarly, agencies that serve 50+ industries (Martal, for instance) can help you break into a niche sector by providing prospect lists and outreach messaging tailored to that industry. Outsourcing allows you to “try before you buy” in new markets – if it works well, you’ve accelerated entry; if not, you haven’t committed to permanent hires.
- Stalling Pipeline or Insufficient Leads: If your sales pipeline is looking sparse or your reps are spending too much time prospecting with little to show for it, an outsourced lead generation service can be the boost you need. Agencies specialize in top-of-funnel activities and can often produce a 3× faster outreach ramp-up than relying on an in-house team alone (5). They can quickly inject qualified leads into your funnel, so your account executives (AEs) can focus on pitching and closing. Many companies turn to outsourcing after realizing their internal prospecting simply isn’t filling the pipeline enough – rather than letting AEs sit idle, they outsource the SDR function to keep the engine running.
- Poor Outbound ROI or Past Campaign Struggles: Perhaps you’ve tried outbound sales campaigns internally (or even worked with another vendor) and results were lackluster – low response rates, high bounce rates, wasted marketing spend. A sophisticated outsourcing agency can bring modern tactics to improve ROI where previous efforts failed. For example, if a company’s emails all went to spam when they tried cold emailing, a reputable agency would use proper domain warm-up, better targeting, and personalization to fix deliverability and boost engagement. We often see firms reach out to Martal after telemarketing or DIY campaigns underperformed, seeking a more data-driven, quality-focused approach. If you know outbound could work but haven’t cracked the code, partnering with experts can turn it around.
- Need for Multi-Channel or Innovative Tactics: Today’s B2B buyers respond across various channels – email, phone, social, etc. If your team is only comfortable with one channel (e.g. email) but you suspect a multi-channel approach would yield better results, an outsourcing agency can execute an omnichannel marketing strategy for you. They come equipped with systems to coordinate touches on all platforms. Moreover, top agencies bring creative tactics you might not do in-house, like sending personalized gifts, hosting “lunch and learn” campaigns (where they send lunch to a prospect’s office ahead of a demo – yes, that’s a thing!), or running account-based plays targeting your competitors’ customers. If you feel your sales approach has gotten stale or one-dimensional, it might be time to outsource to a partner with fresh ideas.
- Budget Constraints / Cost Efficiency Needs: It may sound counterintuitive, but outsourcing can be a solution when budgets are tight. Hiring full-time employees is expensive – not just salaries but also benefits, commissions, office space, tools, and turnover costs. Outsourcing agencies often bundle everything into a simpler fee. You avoid long-term employment liabilities and pay only for what you need, when you need it. For example, instead of hiring an SDR for $8k/month plus overhead, you might get an outsourced SDR service for half that cost. One analysis found outsourcing can cut the fully-loaded cost-per-meeting by roughly 30–50% compared to in-house teams . So if you must increase sales but can’t expand headcount, outsourcing is an efficient path.
In summary, consider outsourcing when your sales ambitions outpace your current capacity or capabilities. If any combination of “not enough leads, not enough time, not enough expertise, or not enough budget” rings true, evaluating outsourcing agencies is a wise move. Many B2B leaders were once reluctant – worried about losing control or quality – but have found that with the right partner, those concerns fade. In fact, 33% of businesses report improved quality and performance through outsourcing because of providers’ processes and technology (7). The key is to identify your specific needs (e.g. more leads, faster market entry, etc.) and choose an agency purpose-built to address those challenges.
How to Evaluate Outsourcing Agencies: Criteria That Matter
Consider expertise, scalability, and technology when evaluating outsourcing agencies, as outsourced teams can lower costs up to 65%.
Reference Source: Martal Group
Not all outsourcing agencies are created equal – and choosing the wrong partner can be costly. To find the right outsource agency for your B2B organization, pay close attention to the following criteria during your evaluation. These factors separate the top-tier agencies from the rest:
1. Relevant Industry Experience: Look for an agency with a track record in your industry or a similar space. Sales outreach is not one-size-fits-all – the messaging and approach that work in one sector may fall flat in another. An agency familiar with your market will understand your customer’s pain points and lingo much faster. Industry expertise shortens the learning curve (1), meaning the agency’s team can hit the ground running. During evaluation, ask for case studies or client examples in your industry (or related verticals). If you sell a technical SaaS product, an agency whose portfolio is mostly SaaS companies will likely perform better than one who primarily serves, say, commercial real estate firms, and vice versa. While domain experience isn’t absolutely mandatory, it’s a big plus that can accelerate results.
2. Proven Track Record of Success: Past performance is a strong predictor of future performance. Any credible outsourcing agency should provide metrics and references from successful campaigns. Look for documented results: e.g. “Client X saw a 40% increase in qualified opportunities in 6 months” or “booked 50+ meetings leading to $Y pipeline.” Check third-party reviews on platforms like Clutch or G2, if available, for unbiased feedback. Ask for references – and actually call them. You want to hear that the agency delivered on promises, communicated well, and contributed to tangible revenue or pipeline growth. An agency unwilling or unable to share success stories is a red flag. The best partners will be proud to showcase results and may even proactively share relevant case studies in your discovery conversations. Remember: You’re not just buying a service; you’re investing in an outcome. So verify the agency has delivered that outcome for others.
3. Services and Capabilities Alignment: Ensure the agency offers the specific services you need and has the capacity to handle your scope. This sounds basic, but it’s crucial. If you need multi-channel global outreach, a boutique firm that only does email in one region won’t cut it. Map your requirements to their offerings. Key questions include: Do they generate the leads as well as follow up, or only one or the other? Can they handle inbound leads if those come in, or strictly outbound? Do they offer content creation if needed (e.g. helping with email copy, landing pages)? How many SDRs or reps will be assigned to your account? Clarify if you’ll get dedicated resources or if they are shared across clients. Also, consider language capabilities and time zones if you target international markets. For instance, if you need EMEA coverage, does the agency have bilingual reps in appropriate time zones? In 2026, many top agencies have global teams and can run 24/7 follow-ups – if that’s important to you, make sure it’s on their menu.
4. Technology and Data Stack: A modern outsourcing agency should be tech-savvy and data-driven. Ask what tools and platforms they use to execute campaigns. Do they have a power-dialer for calls? What email automation or sequencing software do they use? Do they integrate with major CRMs (Salesforce, HubSpot, etc.) to give you visibility? Crucially, inquire about their data sources for contact lists – do they maintain their own database or use providers like ZoomInfo, LinkedIn Sales Navigator, etc.? Quality data is the lifeblood of effective outreach; agencies must maintain verified, updated contact lists. Some firms even have proprietary AI tools for lead scoring or email personalization – these can be differentiators. Also, discuss how they measure success and provide reporting. Leading agencies often have dashboards or at least regular reports on key metrics (response rates, meetings set, SQLs, etc.). You’ll want an agency that leverages advanced tech (AI for research, intent data, analytics) but balances it with human judgment. Tip: Avoid providers that seem “old-school” – e.g. just smiling and dialing without using data – as well as those that overhype automation without human quality control. The sweet spot is a pragmatic use of AI and automation to boost efficiency, combined with human oversight to ensure relevance (9) (7).
5. Communication and Transparency: When you outsource your brand’s sales outreach, communication is paramount. You need an agency that will be a true partner, not a black box. Evaluate their responsiveness and clarity during the sales process – it often reflects how they’ll behave later. Key things to establish: How often will they meet with you (weekly syncs? monthly reviews?) and what will those updates include? Will you have access to campaign data in real-time, or at least frequent summaries? Many top agencies integrate with your CRM or provide shared dashboards so you can see lead statuses anytime. Transparency is a must – you should know who they’re contacting, with what messaging, and what the outcomes are. Additionally, ensure the agency is open to collaboration with your team. The best agencies welcome input on messaging, target profiles, and adjust based on your feedback. They should also proactively communicate any issues (for example, if they see lower response in one segment, they inform you and propose tweaks). Essentially, look for an agency that behaves like an extension of your team. If during evaluation they are slow to respond, evade questions, or seem inflexible about process, consider those warning signs. In contrast, if they are consultative, eager to understand your goals, and transparent about how they work, that’s a good indicator of a healthy working relationship to come (1).
6. Scalability and Flexibility: Your needs might grow (or change) over time, so assess whether the agency can scale with you. If you start with 1 outsourced SDR and want to ramp to 3 or 5 later, can they accommodate that? Top agencies have a bench of trained reps to add quickly as needed. Also, consider contract flexibility – in 2026, many companies prefer month-to-month or short-term trials to test an outsourcing sales partner. Does the agency offer a pilot program or a reasonable out clause if things don’t work out? Beware of firms that lock you into a long contract without a performance-out clause; a confident partner shouldn’t fear a shorter commitment. On the flip side, if you’re seeking a long-term partner, gauge their stability and client retention. An agency that churns clients frequently might not be the stable ally you need for multi-year growth. Scalability also means the ability to ramp down if needed – e.g. if market conditions change, can you pause or reduce scope without penalty? The ideal agency is agile, able to adjust team size, target focus, or strategy in sync with your needs (1). For example, if next quarter you decide to target a new industry, can they quickly reorient and perhaps bring in reps with that industry experience? Flexibility in service is a major asset.
7. Cultural Fit and Team Integration: Though harder to quantify, cultural alignment matters. Your outsource agency’s reps will often interact with your potential customers – so they should mesh with your company’s style and values. During discussions, note how they talk about representing your brand. Do they emphasize understanding your value prop and becoming a seamless extension of your team? You may want an agency whose working style (formal vs. casual communication, process-driven vs. adaptive, etc.) complements yours. If your company culture prizes consultative, quality-driven selling, ensure the agency isn’t all about high-volume, boilerplate outreach. Some B2B firms also prefer onshore teams for cultural familiarity with buyers – e.g., if selling to enterprise US clients, having North America-based reps might be important for rapport-building. Martal Group, for instance, highlights using onshore mid- and senior-level sales talent (North America, EU, LATAM) rather than offshore, outbound call centers, to ensure professionalism and cultural fluency. This can significantly impact how conversations with prospects go. So consider what mix of onshore/offshore you are comfortable with. Additionally, if face-to-face meetings or events are part of your strategy, a local presence might matter. In short, choose a partner you’d be proud to have speak on behalf of your brand, because they essentially will.
8. Compliance and Security: Last but not least, in an age of data privacy and security, verify that the agency follows all relevant regulations. They should be well-versed in laws like GDPR, CCPA, CAN-SPAM, and any cold-calling rules for the regions they operate in. During evaluation, ask how they obtain and process data (are their contact lists GDPR-compliant? Do they scrub against known suppression lists?). A reputable firm will have clear answers and policies. Also inquire about security measures – will they need access to your CRM or systems? How do they protect your prospect data and any sensitive information? Given they act as part of your sales org, you want assurance that they treat compliance as a priority to protect your brand’s reputation. The best agencies often have standard operating procedures to ensure emails and calls comply with local laws and won’t put you at risk. If an agency waves off compliance concerns or seems unaware of regulations, that’s a red flag.
By evaluating outsourcing agencies on these criteria, you’ll build a holistic picture of each candidate. Make a checklist and score each provider if that helps. Ultimately, the right choice will be the agency that demonstrates expertise in your arena, a solid plan (with proof) to deliver results, transparent and proactive communication, and a partnership mindset. When you find that, you can proceed with confidence – and look forward to a productive collaboration that drives real growth. Remember, an outsourcing agency is more than a vendor; they’re an extension of your sales engine. Take the time to choose wisely, and it can significantly accelerate your revenue in 2026 and beyond.

Best-in-class B2B outsource agencies can reach 5,000 prospects per month and accelerate sales cycles by 25%.
Reference Source: Martal Group
Overview: Martal Group is a premium B2B lead generation and sales outsourcing agency known for its data-driven approach and seasoned onshore team. Founded over 16 years ago, Martal has helped 2,000+ B2B tech companies accelerate growth across 50+ industries – from startups to Fortune 500 enterprises. What sets Martal apart is its “Sales-as-a-Service” model: they provide a fractional SDR team (SDRs, account executives, research analysts, etc.) that plugs into your organization to fill your pipeline and even close deals. Martal’s team is spread across North America, Europe, and LATAM, meaning they cover multiple time zones and languages with mid- to senior-level talent, not junior call center agents. They emphasize a tailored approach – learning each client’s unique value proposition and ICP – rather than one-size-fits-all campaigns. Martal’s proprietary AI SDR platform crunches over 3,000 intent signals to build optimized target lists and messaging in real time. This allows Martal to identify “in-market” prospects and engage them at just the right moment. By combining AI insights with human touch, Martal delivers highly targeted outreach via email, LinkedIn, and phone (a true omnichannel cadence) to connect clients with key decision-makers. The results: Martal’s clients often ramp up sales outreach 3× faster and see up to 65% lower cost-of-sale compared to doing it in-house. In short, Martal Group acts as an extension of your sales team, bringing proven processes, advanced tech, and experienced salespeople to drive predictable revenue growth.
Key Features:
- Omnichannel Outbound Campaigns: Every Martal engagement uses a mix of cold email, LinkedIn outreach, and cold calling touches, carefully sequenced. This multiplies contact rates and builds familiarity with prospects across channels, often yielding higher engagement than single-channel efforts. For example, Martal might send a personalized email, then a LinkedIn message referencing that email, then a follow-up call – all coordinated to reinforce the client’s value prop.
- AI-Driven Targeting: Martal’s platform leverages real-time intent data and firmographic/technographic research to pinpoint prospects who are actively looking for the client’s solution. By focusing on high-intent accounts and personalizing messaging to their pain points, Martal achieves better conversion rates than traditional mass-blast approaches. Their system also automates tasks like email validation and optimal send-times to maximize deliverability.
- Onshore Expert Team: Unlike many agencies that outsource execution to junior staff, Martal uses an in-house team of experienced SDRs and sales executives based in the US, Canada, EU, and LATAM. These reps are well-versed in complex B2B sales and can hold quality conversations with senior prospects. The geographic spread means outreach can be timed for local business hours and even conducted in local languages if needed.
- End-to-End Sales Capability: Martal can cover as much of the funnel as needed – from top-of-funnel B2B appointment setting services to providing fractional closers. They offer flexible packages, including pure lead generation or a full sales pod. Notably, Martal’s SDRs will not only book meetings but also follow through to ensure those meetings occur, and their account executives can step in to present demos or close deals if engaged for full-cycle service (2). This “pay as you grow” flexibility is valuable for clients who might start with lead gen and later scale to outsourced closing.
- Training and Consulting: Martal doesn’t just execute campaigns; they also arm clients with knowledge. Through Martal Academy, they provide B2B sales training programs for client teams, covering outbound best practices, pipeline management, and even hiring/management strategies. This means clients benefit not only from immediate lead flow but also improved internal capabilities – a unique value-add.
Ideal For: B2B tech and software companies (from SMB to mid-market and even enterprise) that want to fast-track their sales pipeline growth without building a large in-house team. Martal is especially strong for tech firms targeting North American and European markets, where having onshore outreach reps yields high credibility. If you have a high-value solution and need quality engagements with senior decision-makers – for example, a SaaS platform selling to C-level executives – Martal’s personalized, consultative approach is a great fit. Their services are ideal if you are looking for an ongoing strategic partnership to drive sales (versus a short one-off campaign), as Martal often becomes a long-term growth partner for clients. Companies that have complex offerings or require multi-touch, educated prospects will find Martal’s approach effective. Also, if you’ve tried other lead gen agencies who delivered lots of low-quality leads, Martal would be a refreshing upgrade focusing on higher-quality, sales-ready opportunities.

FAQs: Outsource Agency
What does an outsourcing agency do for B2B sales?
An outsourcing agency provides an external team to handle your B2B sales processes. They generate leads, contact prospects, set meetings, and sometimes close deals—functioning as an extension of your internal sales team. This helps companies scale quickly without hiring in-house.
When is the right time to outsource my sales development?
Outsource when you’re scaling fast, entering new markets, facing bandwidth issues, or not seeing results from in-house prospecting. It’s especially useful during funding rounds, product launches, or when internal hiring is slow or costly.
How do outsourcing agencies charge for their services?
Most charge a monthly retainer based on team size and services. Others offer pay-per-lead or pay-per-meeting models. Some use hybrid pricing—lower base fees with performance bonuses. Always align fees with expected ROI and clear deliverables.
How do I ensure an outsourcing agency represents our brand correctly?
Start with a detailed onboarding process, approve all messaging, and require call/email transparency. Treat them like a part of your team—review calls, give feedback, and hold regular syncs to maintain alignment with your brand and values.
What kind of results can I expect, and how soon?
Most agencies deliver initial meetings within 2–4 weeks. Consistent pipeline typically builds by month 2–3. A strong campaign may generate 10–30 qualified meetings monthly, depending on your industry and target audience.
Is it better to outsource sales or build an in-house team?
Outsourcing is faster and more flexible, ideal for early growth or testing new markets. In-house offers more control but requires time, budget, and infrastructure. A hybrid model—internal closers, outsourced SDRs—is common and effective.
How do I measure ROI from an outsourced agency?
Track meetings booked, lead quality, and revenue generated. Compare pipeline and closed-won deals against agency costs. Use metrics like cost-per-lead and deal conversion rate. ROI = (Revenue – Cost) ÷ Cost. Monitor pipeline value and sales cycle velocity for long-term impact.
