In-house SDRs vs an outbound agency: which books meetings cheaper?
Short answer
Agencies win on speed and month-one cost per meeting ($280–$650 versus $700+ during SDR ramp), but in-house SDRs cost less per meeting from roughly month seven onward and build durable domain knowledge and pipeline quality.
Option A
In-house SDR team
Employed sales development reps prospecting your ICP full time.
Strengths
- Deep product knowledge produces better-qualified meetings
- Feedback loop with AEs and marketing is immediate
- Reps become your future AEs — a talent pipeline, not a cost line
- Data, sequences, and domain reputation stay yours
Trade-offs
- $92,000–$130,000 fully loaded per rep including tools
- Three to five months of ramp before full productivity
- Hiring and attrition risk — SDR tenure averages 14 months
- Requires a manager once you exceed three reps
Option B
Outbound agency
Contracted team running list building, sequencing, and meeting setting.
Strengths
- Live in 2–4 weeks with no hiring cycle
- Fixed monthly cost, cancellable on 30–60 days
- Brings tooling, deliverability infrastructure, and playbooks
- Useful for testing new segments before committing headcount
Trade-offs
- Shallow product knowledge shows up as unqualified meetings
- Meeting-count incentives can degrade lead quality
- You may not own the domains, data, or sequences at the end
- Costs don't fall with scale the way in-house does

In-house overtakes an agency around month seven, once ramp is paid for.
An SDR costs about the same per month as a small agency retainer but produces nothing for the first two months and half-output for two more. Cumulative cost per qualified opportunity therefore favours the agency through roughly month six. From month seven the SDR's higher conversion quality — 35–50% meeting-to-opportunity versus 20–35% — compounds, and by month twelve the in-house cost per opportunity is typically 30–45% lower. Under a 12-month horizon, hire the agency; over it, hire the rep.
Worked example: 12 months, one SDR versus one agency retainer
- SDR: $65,000 base + $15,000 variable + 22% burden = $97,600, plus $9,000 tools = $106,600
- Output: months 1–2 = 0, months 3–4 = 8/mo, months 5–12 = 16/mo → 144 meetings
- 144 × 75% show × 42% qualified = 45 opportunities → $2,369 per opportunity
- Agency: $9,000/mo × 12 = $108,000
- Output: months 1 = 4, months 2–12 = 22/mo → 246 meetings
- 246 × 62% show × 27% qualified = 41 opportunities → $2,634 per opportunity
Nearly identical over a year — $2,369 versus $2,634 per opportunity — but the SDR's cost per opportunity halves in year two while the agency's stays flat.
The verdict
Choose In-house SDR team
Hire in-house if outbound is a permanent motion, your ACV justifies the ramp, and you have a manager to coach.
Choose Outbound agency
Hire an agency if you're testing a new segment, need pipeline this quarter, or lack sales management bandwidth.
Or run both
The common sequence: agency proves the segment for two quarters, then you hire in-house against the playbook it validated.
Frequently asked questions
What should I pay per qualified meeting?
$280–$650 for a set meeting; $1,100–$3,200 for a qualified opportunity. Anything under $200 per meeting almost always means unqualified volume.
How do I keep an agency honest on quality?
Pay on qualified opportunities accepted by your AEs, not on meetings booked, and audit recordings weekly for the first month.
Should an agency use my domain?
Never your primary domain. Insist on separate sending domains you own, so deliverability damage doesn't hit your main email and the assets stay yours.
