At some point, every growing B2B company hits the same question: do we hire someone to do outbound, or do we bring in an agency?
Both can work. Both can also fail expensively. The honest answer depends less on budget and more on a few specific factors most companies don’t think through until after they’ve already made the decision.
Here’s a straight comparison — costs, timelines, risks, and the situations where each option actually makes sense.
The Real Cost of Each Option
In-house SDR
- Average base salary: $55,000–$75,000/year, plus commission and benefits (often pushing all-in cost to $85,000–$110,000/year)
- Recruiting time: 4–8 weeks to hire, longer for a strong candidate in a competitive market
- Ramp time: Most new SDRs take 60–90 days to reach full productivity, even with good onboarding
- Tools: Sales Navigator, a CRM, an enrichment tool, and outreach software typically add $300–$800/month
- Management overhead: Someone needs to coach, review messaging, and hold the SDR accountable — usually a sales manager’s time that isn’t free either
LinkedIn lead generation agency
- Typical retainer: $3,000–$9,000/month depending on scope and volume
- Start time: Most agencies launch the first campaign within 1–3 weeks of onboarding
- Ramp time: Meaningful results typically appear within 30–45 days, since the agency isn’t learning the channel from scratch
- Tools included: Agencies usually bring their own Sales Navigator seats, enrichment tools, and outreach infrastructure
- Management overhead: Minimal — you review results and provide feedback, but you’re not managing day-to-day execution
The quick math: A single in-house SDR often costs more per year than 12 months of an agency retainer, before accounting for the 2–3 months of near-zero output while they ramp up.
Where In-House Wins
Hiring internally isn’t the wrong call for every company. It tends to make sense when:
- You’re selling something highly technical or niche where deep product knowledge is hard to transfer to an outside team
- You have long-term volume — enough consistent pipeline need to keep one or more SDRs fully utilized for years, not months
- You want outbound expertise to live inside the company as a long-term capability, not a rented service
- You already have a strong sales ops function to manage, coach, and retain SDR talent — this role has notoriously high turnover industry-wide
Where an Agency Wins
An agency tends to outperform in-house hiring when:
- You need results faster than a hiring and ramp cycle allows. If pipeline is urgent, waiting 3–4 months for a new hire to become productive is a real cost.
- Your volume doesn’t justify a full-time role yet. Many B2B companies don’t have enough steady outbound need to keep one person fully booked — an agency can flex up or down.
- You want to avoid the LinkedIn learning curve. Outreach limits, account warm-up, message testing, and platform-specific nuance take real time to learn. An agency has usually already made those mistakes on someone else’s campaign.
- You want built-in accountability without managing headcount. A good agency lives or dies by results, which creates a different kind of incentive than an employee’s job security.
A Hybrid Approach Is Increasingly Common
More B2B companies are landing on a middle path: an agency runs LinkedIn outreach for 6–12 months to build and validate the process, prove out messaging, and generate consistent pipeline — and once volume justifies it, the company hires an in-house SDR to take over, often using the agency’s playbook as the starting point.
This gets you the speed of an agency without the long-term dependency, and it means whoever you eventually hire in-house isn’t starting from zero.
How to Decide for Your Business
Ask three questions before choosing either path:
- How urgent is your pipeline need? If you need meetings booked in the next 30–60 days, an agency almost always gets there faster than a new hire.
- Is your outbound volume steady enough to justify a full-time role? If you’re not sure, that uncertainty itself is a signal to test with an agency first.
- Do you have the internal capacity to manage and coach an SDR well? An underperforming SDR with no strong sales management above them rarely improves on its own.
The Bottom Line
There’s no universally correct answer — only the right fit for where your company is right now. What we’d caution against is choosing based on which option “feels” more permanent or more impressive on an org chart. The companies that get outbound right are the ones that match the model to their actual pipeline need and timeline, not the other way around.
