Hiring an in-house SDR seems safer, but the unit economics are brutal. Between fully-loaded salaries ($85k-$120k), 3-month ramp times, and rep turnover, most teams pay $800-$1,200 per held meeting in-house versus $100-$150 with a dedicated outbound partner.
When leadership compares an in-house sdr vs agency model, they often look only at base salary. They forget that an SDR requires payroll taxes, benefits, management oversight, and thousands of dollars in software licenses.
Here is how the real economics look across 12 months of operation:
| Expense Category | 1x In-House SDR | Outboundish Retainer |
|---|---|---|
| Base Salary & OTE | $65,000 - $95,000 | $0 (Included in retainer) |
| Payroll Taxes & Benefits | $12,000 - $18,000 | $0 |
| Outbound Sales Infrastructure (Sales Nav, Smartlead, Clay, Inboxes) |
$14,000 - $20,000 | $0 (Included) |
| Ramp Time to First Meeting | 60 - 90 Days | 7 - 14 Days |
| Annual Cost | $91,000 - $133,000 | $10k - $20k / year |
| Average Monthly Meetings | 8 - 14 meetings | 20 - 30 qualified meetings |
| Effective Cost Per Held Meeting | $600 - $1,000 / meeting | $100 - $150 / meeting |
The biggest flaw in internal sdr unit economics is attrition. The average SDR tenure in B2B tech is just 14 months. When a rep leaves after 9 months of productive outreach, the pipeline freezes, and you restart the costly 90-day hiring and ramp cycle, ballooning your effective cost per held meeting.

For large enterprise organizations with dedicated Sales Ops teams, in-house SDRs can work. But for high-growth B2B teams needing immediate pipeline efficiency, partnering with an agency delivers 3x more meetings at an effective cost of just $100 to $150 per held meeting.

An in-house SDR costs between $91,000 and $133,000 annually including salary, taxes, and tech stack, resulting in $600-$1,000 per held meeting. Outboundish delivers 20-30 meetings per month at an effective unit cost of $100-$150 per held call.
