OneSource Professional Search is a US hiring partner that has been recruiting since 1997. We work with you before, during and after every hire: we bring clarity to the role, run the recruiting work, advise you every week as the market responds, and stay with your new hire through their first month. You always make the hiring decisions.

We're redefining what a staffing agency should be. Most agencies are paid a percentage of the salary or bill rate, which creates a built-in conflict: they earn more when you pay more, and they get paid for filling a seat rather than for the quality of the work.

We use value-based pricing instead: a flat fee per job with RecruiterOS, and a fixed hourly network fee for contract staff. Our earnings don't rise with the salary you offer, so our only incentive is to find you the right person and give you the best service.

We work with US employers of all sizes, with or without an in-house recruiting team. We specialize in engineering, software and manufacturing, and in corporate roles across finance, accounting, HR and operations. We also have a dedicated practice for VC- and PE-backed companies.

It's a simple choice:

• Hiring someone permanent (a direct placement)? Start with RecruiterOS™.
• Need contract or temporary staff? Choose FlexWorkforceOS™.
• Already know it's a hard-to-fill role? Go straight to SearchOS™ direct search.

Not sure? Start with RecruiterOS. If your recruiter sees at intake that the right people aren't actively applying, or applicants dry up later, we'll recommend moving to SearchOS, and what you've already paid carries over.

HiringOS is the platform you use to work with OneSource. On it you:

• Submit job requests
• Approve your Hiring Kit and any add-ons
• Review candidates and give interview feedback
• Approve our weekly recommendations
• Follow your search as it happens

Your recruiter does the hiring work, and HiringOS keeps every step, approval and promise visible.

Your recruiter contacts you to book a hiring intake, where we use our proprietary 5D analysis to understand the role, team and business, from your side and the candidate's.

Within 1 business day of the intake, you receive your Hiring Kit: a clear picture of who you need, a job description written to attract, and why a great candidate should want the job. You review and approve it on HiringOS. Within 1 business day of your approval, your job goes live and recruiting begins.

We need:

• Your time for the intake
• Feedback within 1–2 business days on candidates, interviews and our questions
• The hiring decisions

Your company also issues the official offer, starts background checks and handles employer onboarding. We coordinate those steps and keep your candidate engaged.

We don't replace your HR team. We work alongside them, or directly with your hiring managers if you don't have one.

Our pricing is published and simple. RecruiterOS is $3,900 per job, with lower prices when you buy in bulk. You're charged only when you approve your Hiring Kit.

SearchOS and Executive search pricing, and package deals, are on our Pricing page.

FlexWorkforceOS starts the same way: a job request, an intake and a Hiring Kit, which you approve. The difference is when you pay. You don't pay anything until your chosen contractor confirms.

From then on, you see the worker's pay, the employment costs and our fixed hourly network fee, each shown separately.
