About outsourced recruiting (RPO)

Outsourced recruiting — often sold as RPO (recruitment process outsourcing) — is when a company hands off some or all of its hiring function to an external team. The provider sources, screens, interviews, and sometimes makes offers on the client's behalf, embedded in the client's hiring brand. Engagements range from a single role to the entire talent function, billed by retainer, monthly subscription, or per-hire.

RPO sits between two more familiar options: contingency recruiting (pay only when you hire) and an in-house TA team (full salary load, fixed cost). It works best for companies hiring at predictable volume — 20+ roles a year — where the math on a dedicated external team beats the cost of a recruiter on payroll. It also works for project-based bursts: a new office, a funded growth round, a category launch.

The agencies below all offer outsourced recruiting services across various sectors. Some run full-cycle RPO programs (sourcing through offer); others handle the front of the funnel only (sourcing + screening, then hand qualified candidates to the client's hiring managers). Pricing models, sector specialization, and team size vary — start with the ones that match your scale and the kind of roles you hire most often.

outsourced recruiting (RPO) — frequently asked

What does RPO stand for?
RPO stands for Recruitment Process Outsourcing. It's an engagement model where a company hands off all or part of its hiring function to an external team that operates as an extension of the client's brand — sourcing, screening, interviewing, and sometimes managing the offer process. RPO is distinct from contingency recruiting (pay-per-hire) and traditional staffing (temporary placements).
When does outsourced recruiting (RPO) make sense vs. building an in-house team?
RPO usually beats an in-house team economically when you hire fewer than ~50 roles per year — the fixed cost of a full-time recruiter on payroll (salary + benefits + tooling + management overhead) is high enough that an external team with a monthly retainer comes out cheaper per hire. Above that volume, in-house starts to win. RPO also wins for project bursts (new office opening, growth round, category launch) where you need recruiting capacity for 3–9 months without committing to a permanent hire.
How is RPO pricing structured?
Three common models: (1) Monthly retainer — fixed fee per month regardless of hire volume; predictable for the client. (2) Per-hire — a fixed fee per accepted offer, usually 15–25% of first-year salary, often discounted vs. contingency rates because the client commits to volume. (3) Hybrid — a smaller monthly retainer plus a per-hire success fee. Enterprise RPO deals usually involve a setup fee plus 12–24 month commitment.
What's the difference between full-cycle RPO and partial RPO?
Full-cycle RPO covers everything from sourcing through offer acceptance — the provider becomes the hiring function. Partial RPO (sometimes called sourcing-as-a-service or embedded recruiting) covers only specific stages — usually the front of the funnel (sourcing and screening), with the client's own hiring managers running interviews and making decisions. Partial is cheaper but requires more client involvement; full-cycle is more expensive but lower lift.
How long does a typical RPO engagement last?
Most ongoing RPO contracts run 12–24 months with renewal options — long enough that the provider can build deep knowledge of the client's roles, culture, and hiring rubric. Project-based RPO engagements run 3–9 months, scoped to a specific hiring burst. The longer the commitment, the deeper the discount; one-off projects pay closer to standard contingency rates.
