In-House SDR vs Outsourced SDR: What It Really Costs

Year one, side by side

Figures below assume one seat, Western European salary levels, and a company starting outbound from scratch.

The costs nobody puts in the spreadsheet

• Attrition: median SDR tenure is well under two years — a departure in month eight means restarting the whole cycle
• Opportunity cost of ramp: six quiet months is six months of pipeline you never built
• Playbook risk: a junior SDR without a proven ICP and script is being asked to invent strategy, which is not their job
• Domain damage: an untrained sender can burn your main domain's reputation in weeks
• Your own time: the first hire fails most often because nobody senior had time to coach them

Where in-house genuinely wins

• Deep, technical products where a year of product knowledge is what makes the call work
• Long sales cycles with heavy account ownership and constant context handoffs
• You already have a working playbook and simply need more seats running it
• You have a sales manager with real coaching capacity, not just a job title
• Three or more seats — at that scale the per-meeting economics flip in-house's favour

Where outsourcing genuinely wins

• You have never run structured outbound and do not know which ICP responds
• You need pipeline this quarter, not in month five
• Founder or existing sales team is already at capacity
• You want to test two or three segments before committing headcount
• Budget exists for €10–20k of testing, not €80k of committed salary

The sequence that works best

For most companies under €5M revenue, the answer is not either/or — it is order of operations.

• Months 1–3: outsource. Prove which ICP replies, which message books meetings, which channel carries it
• Months 4–6: keep running while you document the playbook — lists, scripts, objections, sequencing
• Month 6+: hire in-house and hand over something that already works, cutting ramp from six months to six weeks
• Keep the outsourced channel running in parallel if the new hire is covering a different segment

One senior operator versus one junior seat

There is a third variable most comparisons ignore: seniority. An outsourced junior caller reading a script is not the same product as a senior salesperson who has spent 11+ years selling into your kind of buyer. The first is cheap activity; the second is judgement on the call — knowing when to push, when to reframe and when to disqualify.

That difference shows up in a single metric: how many of the booked meetings your sales team considers worth having. Ask any provider for that number before comparing prices.

FAQ

What does an in-house SDR really cost per year?

In Western Europe, €55,000–€80,000 all-in: base salary, commission, employer taxes, tools, data, and management time. In the Baltics and Central Europe it is closer to €30,000–€45,000, but the recruiting pool is smaller.

How long before a new SDR books consistent meetings?

Three to six months. Month one is onboarding, month two is early attempts, and steady output usually starts in month three or four — assuming they stay.

Is outsourcing SDR work cheaper?

In year one, almost always, because you skip recruiting, ramp and severance risk. Once you need three or more full-time seats and have a proven playbook, in-house usually becomes cheaper per meeting.

Can I do both?

Yes, and it is often the smartest sequence: outsource first to prove the ICP, channels and messaging work, then hire in-house and hand over a playbook that is already producing meetings.

What is the biggest hidden cost of hiring in-house?

Management time. A first SDR needs 3–5 hours a week of coaching from someone senior. If nobody has that time, the hire fails regardless of the person's talent.
