In-House SDRs vs Appointment Setting Agency: The Real Cost Breakdown

"Should I hire an SDR or use an appointment setting agency?" , it's the question every B2B founder asks at some point, usually right after realizing their pipeline needs help. Both paths can work. Both have real trade-offs. And the honest answer depends less on cost than most people think.

Here's the real math, side by side, without the sales pitch.

The real cost of an in-house SDR

Most founders anchor on base salary and stop there. The full cost is 2 to 3x higher:

• Base + OTE: $65 to 90k depending on market
• Benefits, payroll tax, equipment: ~25% loaded on top
• Tools (Apollo, Outreach/Salesloft, LinkedIn Sales Nav, list enrichment): $500 to 1,200/month
• Sending infrastructure (domains, inboxes, warm-up): $200 to 500/month
• Manager time to coach and review , usually 5 to 10 hours/week from a director

All-in: $110 to 150k for year one, before you count the 3 to 6 month ramp when they're producing very little.

The real cost of an appointment setting agency

A legitimate B2B agency runs $3,500 to 7,500/month, which is $42 to 90k for the year. That includes infrastructure, copy, list building, reply management, and reporting. No ramp , meetings usually start landing in weeks 3 to 5.

Side-by-side comparison

When in-house wins

• You already have 3+ AEs and need a repeatable SDR-to-AE pipeline
• You have someone senior who's run outbound before and can coach
• Your product needs deep technical explanation an outside team can't fake
• You're playing the long game , 2+ years and want the muscle in-house

When an agency wins

• You need meetings this quarter, not next year
• You've never run outbound and don't want to learn deliverability the hard way
• Your team is small and can't spare time to manage an SDR
• You want to test whether outbound works for your offer before committing to a hire
• You've hired SDRs before and they underperformed

The hybrid model

A growing number of B2B companies run both: an agency handles top-of-funnel volume, and one in-house SDR focuses on high-value named accounts. Agency fills the calendar; the internal rep chases the whales. It's more expensive but tends to be the highest-output setup for companies past $2M ARR.

The wrong question

"Which is cheaper?" is the wrong question. The right one is: what gets qualified meetings on my calendar the fastest with the least risk? For most B2B founders under $5M ARR, the answer is almost always an agency , for 12 months , then a decision.
