Whether an in-house or an outsourced SDR pays off more isn’t decided by the monthly price, but by a single number: what a properly qualified conversation (SQL) costs you – one that your Account Executive actually turns into pipeline.
“An outsourced SDR is too expensive for us.” We hear this sentence at Strive Sales almost every week. Usually there’s a simple comparison behind it: the gross salary of an in-house SDR on one side, the monthly invoice from an agency on the other.
The problem: this comparison leaves out half the costs – on both sides. Outsourced SDRs have hidden costs too if the partner isn’t the right fit. In this article, we compare both models honestly, work through them with example figures and show you which question you should be asking instead.
What an in-house SDR really costs
In the first year, an in-house SDR doesn’t cost you their salary, but around 1.7 times that. With an annual salary of €50,000 (including variable pay), it looks roughly like this:
| Cost item | Per year | Assumption |
|---|---|---|
| Gross salary incl. bonus | €50,000 | Junior SDR, DACH |
| Employer social security contributions | €10,500 | approx. 21% |
| Management and coaching | €10,000 | approx. 3 hrs/week of a manager listening to calls and giving feedback |
| Recruiting | €8,000 | Job ads, interviews, recruiter if needed |
| Tools and data | €4,000 | CRM licence, Sales Navigator, dialler, contact data |
| Workplace and equipment | €2,500 | Laptop, headset, software |
| Total | €85,000 | = 1.7 × gross salary |
On top of that come costs that don’t appear on any invoice: holidays and sick leave (around 40 working days a year without output), the onboarding period at half capacity and the risk that the SDR leaves again after a few months. These don’t show up in the price, but in the number of SQLs – more on that shortly.
In-house SDR: pros and cons
An in-house SDR pays off above all when the sales system around them is already in place.
Pros
- Full control: You decide on target audience, messaging and priorities every day.
- Product knowledge grows in-house: The SDR sits close to product, marketing and AEs and gradually understands every detail.
- Learnings stay with you: Objections, messaging and market feedback flow straight into your company.
- Career path: Good SDRs become your AEs of tomorrow.
- Cultural fit: A team member identifies more strongly with the brand and mission.
Cons
- High total cost: around 1.7 times the gross salary in the first year.
- Long ramp-up: Hiring, notice periods and onboarding can easily take four to six months before full capacity is reached.
- Management takes time: Without someone listening to calls and coaching every day, quality falls short of what’s possible.
- The playbook gets built on the side: You have to develop scripts, sequences and qualification criteria yourself.
- Concentration risk: If your one SDR is off sick or quits, your pipeline grinds to a halt.
Outsourced SDR: pros and cons
An outsourced SDR pays off when you need pipeline fast – but only with the right partner.
Pros
- Fast start: Playbook, training and management already exist. After four to six weeks, the SDR is running at full capacity.
- Absences are covered: Holidays, sickness or resignations are absorbed by the provider. Capacity is contractually guaranteed.
- Experience across many markets: Good agencies know which messaging works in which industry.
- Predictable costs: One fixed monthly fee instead of salary, recruiting, tools and management time.
- Flexible scaling: Ramp capacity up or down without hiring or firing.
Cons
An honest look is worthwhile here, because not every provider delivers what they promise:
- Meetings over quality: Many lead-gen agencies are paid per meeting. Whether the prospect fits your ICP then becomes secondary.
- Onboarding is still needed: An outsourced SDR also has to understand your product. They need to connect the customer’s pain with the value of your solution and be able to ask the right qualifying questions.
- Documentation outside your CRM: Some providers work in their own systems. Call notes are then missing when your AE needs them.
- Changing contacts: At some agencies, SDRs rotate constantly and knowledge is lost every time.
- Learnings stay external: Without regular exchange, market feedback never reaches you.
- Low-cost models: Providers who employ their SDRs on low wages or as rotating freelancers rarely deliver consistent quality.
Worked example: what does an SQL cost?
In our example, an SQL costs around €1,230 in-house and around €840 outsourced – and if the in-house SDR quits after seven months, the price rises to almost €1,770.
The assumptions: equally good talent on both sides, 8 SQLs per month at full capacity. The outsourced SDR costs €6,000 per month. On top of that, we add €3,500 per year for your own time in the weekly alignment meeting.
Scenario 1 – the first year runs normally
- In-house: Three months of onboarding at half capacity, then full capacity. Holidays and sickness cost around 18% of working days. Result: about 69 SQLs.
- Outsourced: One month at half and one month at three-quarter capacity, then full capacity. The partner covers absences. Result: about 90 SQLs.
Scenario 2 – the in-house SDR quits after seven months
Finding a successor takes three months, and they then have to be onboarded again. Recruiting costs are incurred twice. By the end of the year, you have around 44 SQLs. With an outsourced partner, the change barely registers: the partner provides a replacement and you lose perhaps two or three weeks.
| Scenario | Cost per year | SQLs per year | Cost per SQL |
|---|---|---|---|
| In-house, normal year | €85,000 | 69 | €1,234 |
| In-house, resignation after 7 months | €77,900 | 44 | €1,767 |
| Outsourced, normal year | €75,500 | 90 | €839 |
| Outsourced, SDR change | €75,500 | 86 | €878 |
With a similar budget, the outsourced SDR delivers around 30% more SQLs in a normal year, and each SQL is around a third cheaper. In the resignation scenario, an in-house SQL even costs twice as much.
That’s not down to the SDR. It’s the price of building sales on a single person without a system around them. All figures are example values – be sure to run the numbers with your own.
The catch: an SQL is only worth as much as its quality
The cheapest meeting is worthless if your AE can’t turn it into an opportunity. That’s why the price per SQL alone isn’t enough – what matters is how much of it becomes solid pipeline.
For us, an SQL is a lead that has been properly qualified using BANT or SPICED. How many of them your AE converts into real opportunities determines the actual cost:
For comparison, we add a third option: an “appointment factory” that delivers around 130 meetings a year for €4,000 per month. Sounds cheap. But many of them don’t fit the ICP, and your AE spends around an hour on preparation and the call for each unsuitable meeting.
| Model | Cost per SQL | Conversion to opportunity | Cost per opportunity |
|---|---|---|---|
| Outsourced partner focused on quality | €839 | 55% | €1,525 |
| In-house SDR, normal year | €1,234 | 60% | €2,057 |
| Appointment factory incl. wasted AE time | €456 | 20% | €2,281 |
The appointment factory has the lowest price per meeting – and the highest price per real opportunity. This is exactly where the hidden costs of outsourced SDRs arise: not on the invoice, but in your AE’s calendar.
In-house or outsourced: what fits when
There’s no one-size-fits-all answer – but there are clear signals.
| An in-house SDR is the better fit if … | An outsourced SDR is the better fit if … |
|---|---|
| you already have a sales leader who can coach daily | nobody in the company has time to manage SDRs |
| your playbook, ICP and qualification criteria are proven | you still want to validate your ICP and messaging |
| your product is highly complex and requires deep expertise | you need pipeline in three months, not six |
| you want to build a whole SDR team in the long run | you want to scale flexibly or test new markets |
Many companies also take a hybrid route: start outsourced, sharpen the playbook and ICP, and later take it in-house with a proven system.
Checklist: how to recognise a good outsourcing partner
- Payment is based on qualified conversations, not meetings in the calendar.
- SQL criteria (e.g. BANT or SPICED) are agreed together in advance.
- The SDR works directly in your CRM and documents every conversation.
- You have fixed contacts instead of constantly changing SDRs.
- Playbook and results are reviewed together at least once a week.
- Learnings, objections and messaging tests are fed back to you.
- The SDRs are paid fairly and managed professionally.
Conclusion: ask the right question
“What does an SDR cost per month?” is the wrong question. The right ones are:
- What can an SQL be allowed to cost me? That is, a lead properly qualified using BANT or SPICED.
- What percentage of them does my AE need to turn into real opportunities for it to pay off? In other words: how much becomes solid pipeline?
Once you know these two numbers, the question of in-house or outsourced almost answers itself. A good outsourcing partner often wins the calculation because ramp-up, absences and management are already priced in. A bad one loses it despite the low price, because they deliver meetings instead of pipeline.
