The Cost of Hiring

The cost of adding In-House Reps

A single in-house SDR seat costs a bit more than just their salary. Once you add employer burden, tooling, management, etc., you’re looking at $9,750 to $15,000+ every month. These benchmarks show the low, typical, and high scenarios of where most teams land.

“I had zero luck with cold outreach before partnering with OSP, but 2 days in and we had 18 meetings booked. No idea how these guys do it, but we had so many meetings it was overwhelming!”

“Just met with a prospect – they started the call by saying, I wanted to compliment you on your cold call because I never take a meeting like this.”

FAQs

Questions? Answered

What is outsourced cold calling?

Outsourced cold calling means a trained SDR team makes your prospecting calls for you, instead of you hiring, training, and managing reps in-house. OSP's callers dial your target accounts, hold real conversations, qualify interest, and book meetings directly onto your calendar, so your closers spend their time selling instead of prospecting.

What is a fractional SDR, and how is it different from hiring one?

A fractional SDR is an outsourced rep who dials on your behalf without going on your payroll. You get the output of a ramped caller without the recruiting, salary, tools, and management a hire brings. You can also add or remove calling capacity month to month instead of committing to permanent headcount.

Does cold calling still work in 2026?

Yes, when the list is tight and the caller is good. OSP's teams average around a 10.5% connect rate, close to 1 in 9 dials, against an industry norm of 1–8%. Untargeted, high-volume dialing is what stopped working. Calling a defined ICP with a relevant reason to call still books meetings every day.

How many dials and meetings can I expect?

It scales with your program. Across all clients, OSP places 270K+ dials a month and books 650+ qualified meetings, but your numbers depend on your ICP, offer, and how many SDRs you run. We set a target with you during onboarding and report against it, rather than promising a fixed number up front.

What is parallel dialing?

Parallel dialing runs several phone lines at once and connects your SDR the instant a prospect picks up. Traditional cold calling gets a rep 40–60 dials a day. Parallel dialing pushes that past 500, so your team reaches more live people in less time and you get to market signal, and booked meetings, faster.

Do real people make the calls, or is it AI?

Real people. OSP is human-first: trained SDRs run every conversation, backed by talk tracks and AI that handles the busywork behind the scenes. A live human on the phone is what turns a connect into a real conversation, and a real conversation into a booked meeting. AI supports the reps, it doesn't replace them.

How long until the SDRs are ramped and productive?

OSP's SDRs are trained on cold calling before they ever touch your account, so there's no three-month ramp like a new in-house hire. After a short onboarding to learn your ICP, offer, and talk track, they start dialing. Most clients see live conversations and first meetings within the opening weeks.

How does outsourcing compare to hiring an in-house SDR?

A single in-house SDR seat runs roughly $9,750 to $14,425 a month once you add tools, data, and management on top of base salary, and it takes about three months to reach full productivity. OSP starts producing sooner with no overhead to carry, and you can scale up or down as your pipeline needs change.

Who writes the call scripts and talk tracks?

OSP's team builds the talk tracks, and you approve them before any dialing starts. You shape the messaging, the qualifying questions, and the positioning up front, then refine as real call data comes in. The script stays true to how your brand talks and what your buyers actually respond to.

Do the SDRs book meetings directly on my calendar?

Yes. When a caller reaches a qualified prospect and confirms interest, the meeting goes straight onto your calendar, not into a list for your team to chase later. Your closers walk into scheduled conversations with prospects who already agreed to talk.

What does OSP cold calling cost?

OSP runs on monthly retainer, starting around $6,500/month, with no per-call or per-meeting fees. Pricing scales with dial volume and the number of SDRs on your account. Most clients start on a 60 to 90 day engagement so the program has time to ramp.
