Software Integration Guide for Staffing Agencies

Ask which tools in a staffing agency's stack "integrate" and the honest answer is: almost everything connects to Google Workspace or QuickBooks Online, and a shorter, ATS-dependent list connects directly to whichever front-office platform you picked. Outside those three hubs, most tools don't talk to each other at all — and in staffing specifically, that matters because candidate data, timesheets, and billing all need to reach the same back office eventually.

The three hubs

Google Workspace, QuickBooks Online, and your ATS are the three nodes almost everything else connects through.

Google Workspace connects directly to 1Password, DocuSign, Huntress, and Bullhorn specifically — the widest reach of any admin tool in the stack, which is why it's priced as the practice-wide productivity layer rather than a per-department tool. QuickBooks Online connects directly to Gusto, Ramp, Bill.com, and TempWorks — the finance cluster's hub, and the one place placed-worker billing and internal payroll are both supposed to land before your bookkeeper closes the month. Your ATS connects outward to the rest of the stack, but how far depends entirely on which one you picked: Bullhorn reaches four tools natively, JobDiva and Crelate reach two each.

Where the ATS hub actually reaches — and where it doesn't

Indeed lists all three ATS platforms as connections, so job-board sourcing flows into whichever front office you run. TempWorks is the narrowest: it lists Bullhorn only, which means a JobDiva or Crelate shop running TempWorks for back-office payroll is bridging that connection manually — every pay cycle, not just at setup. And if you're running Crelate specifically, both Checkr and LinkedIn Recruiter fall outside its native list, so background-check ordering and passive sourcing (if you ever add it) both become separate, unlinked workflows.

The back-office cluster reaches further than the ATS realizes

TempWorks connects to Bullhorn, QuickBooks Online, and QuickBooks Time. WorkBright — the onboarding tool that collects I-9s and tax forms — connects only to Checkr and TempWorks, with no direct line to any ATS at all, on any platform. In practice, that means a new placement's onboarding paperwork reaches the back office only by routing through Checkr and TempWorks first, and it only closes the loop back into the candidate record automatically if TempWorks' one native ATS connection — Bullhorn — is the platform you're running.

Security tools protect the endpoint, not the candidate record

1Password and Huntress connect to each other and to Google Workspace, not to the ATS or Checkr directly. That means your password manager and endpoint detection cover the devices recruiters use to access candidate data — they don't give you visibility inside Checkr's own access logs for who pulled a specific background-check result. That accounting-of-access question is Checkr's job, not Huntress's or 1Password's.
