Where they pull apart

ClearStar

Stands out: Screening plus occ-health (ClearMD) in one CRA family, which matters when drug and physicals sit beside the criminal package.

Watch out: Quote-only. Office-only employers will over-buy occ-health they do not use.

Not the right fit for

  • SMBs that want a $29.99 criminal package
  • Pure SaaS office hiring
  • Teams that only need an API wrapper

First Advantage

Stands out: Background and identity checks across more than 200 countries and territories, with ATS integrations and REST APIs.

Watch out: No published per-check price. Former Sterling customers are moving onto First Advantage, so confirm which platform your contract runs on.

Not the right fit for

  • Small firms wanting a published per-check price
  • Individuals ordering a personal check
