"Why would I pay an agency when I can just hire someone?" It is the most reasonable objection in B2B, and it deserves numbers, not opinions. The problem is that almost everyone does the math wrong: they compare the rep's salary with the agency's invoice. And that comparison is broken from the start.
Salary is only one part of the cost of an in-house rep. It leaves out payroll taxes, tools, data, training, ramp-up months, role turnover and the time of whoever manages them. When you add it all up, the picture changes so much that the decision stops being obvious.
In this article we do the full math with 2026 benchmarks, in euros and dollars, with companies in Spain and LATAM in mind. And we do it honestly: we also tell you when hiring in-house is the better call.
What does an in-house sales rep really cost?
The real cost of an SDR (the role dedicated to prospecting) is not their salary: it is their fully loaded cost. According to 2026 industry benchmarks, in Europe that cost ranges from 65,000 to 120,000 euros per year per person. The figure makes sense once you break it down:
- Salary and variable: in Spain, an SDR with some experience costs between 28,000 and 45,000 euros gross per year, plus commissions per meeting or pipeline generated.
- Payroll taxes: roughly an extra 30 % on top of gross salary that rarely shows up in the comparison.
- Tools and data: CRM, sequencer, B2B database, phone system and enrichment easily add several hundred euros per month per seat.
- Training and onboarding: materials, shadowing time from other reps and learning mistakes paid for in burned opportunities.
- Management: leadership time, which almost nobody accounts for and which we cover below.
On top of that cost, two clocks run against you. The first is ramp-up: an SDR takes 4 to 6 months to produce reliable results. The second is turnover: the role sees annual turnover between 30 % and 50 %, with an average tenure of 14 to 20 months. Translated: you pay for 4 to 6 months of learning, enjoy 10 to 14 months of full performance, and start over from zero, with another ramp and another hiring process.
What does a B2B agency include, and what does it cost?
A serious B2B prospecting agency costs between 1,300 and 12,000 euros per month depending on scope, markets and channels (you can see real ranges on our pricing page). The key difference is what that price includes, because it covers almost everything you pay for separately in the in-house model:
- Verified data: lists built and validated against your ICP, without paying for your own database licenses.
- Technical infrastructure: secondary domains, mailboxes, warm-up and deliverability monitoring.
- Multichannel execution: copywriting, sending, follow-up and meeting booking, with reporting included.
- Accumulated learning: playbooks proven across dozens of accounts, which saves you from paying for a junior's mistakes with your own market.
The structural difference is time: the agency has no six-month ramp because it arrives with the system already built. The first meetings usually show up between week 4 and week 8.
The metric that decides: cost per qualified meeting
List price tells you nothing. What matters is cost per result, and in prospecting the result is called a qualified meeting. At fully loaded cost, a meeting generated by an in-house SDR costs between 821 and 1,150 dollars. The same meeting, in an outsourced model, runs around 300 to 600 dollars. It is not that the agency is cheap: it spreads infrastructure, data and learning across many clients, while the in-house SDR loads their entire cost onto your meetings.
| Criterion | In-house SDR | B2B agency |
|---|---|---|
| Monthly cost | 5,400 to 10,000 € (fully loaded) | 1,300 to 12,000 € depending on scope |
| Time to results | 4 to 6 months of ramp-up | 4 to 8 weeks |
| Cost per qualified meeting | 821 to 1,150 US$ | 300 to 600 US$ |
| Main risk | 30-50 % annual turnover: the asset leaves with the person | Flexible contract: adjust or cancel without severance |
| Management load | 10-20 % of the sales leader's agenda | One review meeting and a periodic report |
The hidden cost nobody adds up: management time
Managing a junior rep consumes between 10 % and 20 % of the sales leader's agenda: training, call reviews, message edits, motivation and activity control. That time has a real opportunity cost. If your sales director costs 90,000 euros a year and spends 15 % of their time managing the SDR, that is 13,500 euros a year nobody charges to the channel. And every hour spent coaching prospecting is an hour not spent closing what is already in the pipeline.
When DOES it make sense to hire in-house?
Here is the part few agencies will tell you: there are scenarios where in-house wins, and it pays to recognize them before signing anything.
- When a proven system already exists: defined ICP, validated messaging and a channel that works. The hire executes a playbook instead of inventing one, and the ramp shortens.
- When the sale demands deep product knowledge: in highly technical or regulated sales, internal context outweighs first-touch efficiency.
- When volume justifies a team: past a certain sustained monthly meeting volume, the marginal cost of each internal meeting drops and the math balances out.
- When you can afford the curve: cash for 6 to 12 months without full returns and a leader with real time to train and retain.
If you do not meet at least two of these conditions, hiring in-house as your first move is usually the expensive option dressed up as the prudent one.
The hybrid model: the mature answer in 2026
The "in-house or outsourced?" question is a trap, because the answer from the best-performing teams is "both, in phases". Outsourced wins on speed, predictability and lower risk during year one. In-house wins on business knowledge from year two onward. The hybrid model combines the two: the agency runs the top of the funnel (data, infrastructure, first touch and meeting generation) and your team keeps what truly requires context, the sales conversations. Over time, the playbook validated by the agency becomes the manual for your first in-house SDR, who steps into a system that already works instead of discovering it at your expense. That is the logic of a predictable growth system: system first, people second.
Frequently asked questions
How much does an in-house SDR cost in Spain in 2026?
Between 65,000 and 120,000 euros per year at fully loaded cost: salary, payroll taxes, tools, data, training and management. Gross salary is only one part, typically between 28,000 and 45,000 euros plus variable.
What is a reasonable cost per qualified meeting?
2026 benchmarks put an internally generated meeting at 821 to 1,150 US$ and an outsourced one at 300 to 600 US$. What is reasonable depends on your ticket: the meeting should cost a small fraction of the annual value of the client that can come out of it.
How long does a B2B agency take to deliver results?
The first qualified meetings usually arrive between week 4 and week 8, the time needed to build the list, warm up the sending infrastructure and tune the message. An in-house SDR, by contrast, needs 4 to 6 months of ramp-up to produce reliably.
Does an agency work if my deal size is small?
It depends on the math. If a meeting costs 300 to 600 US$ and your average client leaves little annual margin, one-to-one prospecting (in-house or outsourced) will be hard to make profitable and higher-volume channels make more sense. Personalized prospecting shines with mid and high tickets.
Can I start with an agency and bring it in-house later?
Yes, and it is the most sensible path for most companies. The agency validates ICP, message and channel during year one; then you hire in-house on top of a proven playbook, with a much shorter ramp.
Do the math with your own numbers before deciding
The decision is not ideological, it is arithmetic. Add up the fully loaded cost of the hire (salary, taxes, tools, data, training and 10-20 % of your own agenda), divide it by the realistic number of meetings they will produce after ramp-up, and compare that cost per meeting with an outsourced model. If the gap is large and you do not meet the conditions to internalize, the numbers have answered for you. And if you want to run that math with your real figures on the table, book a session and we will build it with you, whatever the result.
