In-House SDR or Prospecting Agency: The Honest 2026 Comparison
Hiring an SDR (a salesperson dedicated to prospecting) costs €3,700 to €5,000 a month fully loaded, while an agency charges €500 to €2,000. But comparing sticker prices isn't enough: ramp-up time, tooling, turnover, and versatility completely change the equation. Here's the honest head-to-head, line by line, to help you decide based on your situation.
- Full cost of a junior SDR: €4,200 to €5,500/month once you count payroll taxes, tools, and management time.
- An equivalent agency: €500 to €2,000/month, operational within 2 weeks.
- The SDR wins once prospecting becomes a full-time job inside your company (beyond 30 to 40 meetings/month to handle).
- Below that, an agency delivers a cost per meeting 2 to 4 times lower.
The Short Answer: It Depends on Your Target Volume
If you're aiming for fewer than 20 to 30 qualified meetings a month, an agency is almost always the best total-cost option. Beyond that, once prospecting becomes a permanent function of the company and you want to build the skill in-house, hiring becomes worthwhile. In between, many companies combine both: an agency to produce, a senior salesperson to close.
What Does an In-House SDR Really Cost?
Salary is only the visible part. Here's the full cost of a junior SDR in France in mid-2026.
| Cost item | Monthly amount |
|---|---|
| Gross salary (€28k to €35k/year) | €2,300 to €2,900 |
| Employer payroll taxes (about 42%) | €1,000 to €1,250 |
| Tools (Sales Navigator, sequencer, enrichment, CRM) | €250 to €450 |
| Onboarding, training, management (amortized) | €400 to €700 |
| Total fully loaded cost | €4,200 to €5,500 |
Add two realities of the role that rarely make it into the budget: ramp-up time (an SDR produces little during their first 2 to 3 months) and turnover, among the highest of any sales function (often 12 to 18 months in the role). A departure resets the ramp-up clock to zero.
How Much Does the Agency Option Cost for an Equivalent Volume?
To produce what a junior SDR produces across digital channels (LinkedIn + email), plan on €1,000 to €2,000 a month with an agency, database, copywriting, and management included, with first meetings in 2 to 3 weeks. A full breakdown of models and contract pitfalls is in our guide to choosing an agency, and the complete price ranges by approach are in how much does lead generation cost.
In-House SDR vs. Agency: The Head-to-Head
| Criterion | In-house SDR | Specialized agency |
|---|---|---|
| Full monthly cost | €4,200 to €5,500 | €500 to €2,000 |
| Time before production | 2 to 3 months (hiring + ramp-up) | 2 to 3 weeks |
| Tooling/copywriting expertise | To be built | Already in place |
| Product knowledge | Excellent over time | Good, never perfect |
| Cold calls, trade shows, field work | Yes | Rarely included |
| Risk (departure, hiring mistake) | High | Low (3-month commitment) |
| Internal capitalization | Yes, the skill stays | Partial (process and database stay if the contract provides for it) |
When Should You Hire? When Should You Delegate?
Hire an SDR if phone or field prospecting is central to your industry, if you already have a sales manager to oversee them, and if your volume justifies a lasting full-time role. Delegate if you're looking for meetings quickly, without additional management overhead, on a controlled and reversible budget. And if you're still unsure about the very principle of automation, the complete guide to automated prospecting covers the basics.
At Skalia, our AI-powered automated prospecting offer plays exactly this outsourced-team role: a simple quote (free audit), a 3-month commitment, first leads in 2 to 3 weeks. Let's talk about your situation if you want an honest opinion on the best option for you.
Key Takeaways
- Real full cost of a junior SDR: €4,200 to €5,500/month, ramp-up of 2 to 3 months and high turnover included in the equation.
- Equivalent agency across digital channels: €500 to €2,000/month, productive within 2 to 3 weeks.
- Below 20 to 30 meetings/month targeted, an agency almost always wins on cost per meeting.
- Hiring is worthwhile once prospecting becomes a permanent, managed function.
- The hybrid model (agency to produce, senior hire to close) is often the best of both worlds.
FAQ: In-House SDR or Agency
What Exactly Is an SDR?
SDR (Sales Development Representative) refers to a salesperson dedicated to prospecting: they generate and qualify meetings, which a senior salesperson (Account Executive) then turns into clients.
Can an Agency Really Understand My Product?
Well enough to open relevant conversations, thanks to a serious scoping phase. For fine-grained qualification and closing, your expertise remains irreplaceable — that's precisely how the roles split.
What About a Freelance Prospector Instead of an Agency?
It's a middle-ground option (often €500 to €1,500/month). Quality varies enormously from one freelancer to the next, and continuity isn't guaranteed; apply the same selection criteria you would to an agency.
Can You Start With an Agency and Then Bring It In-House?
Yes, that's even a classic path: the agency validates the market and builds the process, then you hire once volume justifies a full-time role, taking over the database and sequences if your contract provides for it.
