Justworks vs Rippling for a Multi-Clinic PT Network

Several states participate in the Physical Therapy Compact, which lets a PT or PTA who holds a compact privilege practice across member states without a separate full license in each one. That's a real convenience for staffing across your network, but it's a licensure mechanism, not a payroll one.

A therapist covering shifts at clinics in two compact states still triggers ordinary state payroll tax and unemployment registration in both, the same as it would for any multi-state W-2 employee, compact privilege or not. Don't let easier licensing create the impression that payroll setup got easier too.

Start with a straightforward map: every clinic location by state, every PT and PTA's primary clinic, and anyone who regularly covers shifts at a clinic outside their primary state. Networks that grew through acquiring or merging with other practices often carry unmapped complexity here, a PT technically on one clinic's books who's been covering a nearby out-of-state clinic for months without anyone updating the payroll registration to match.

Many PT networks pay a base salary plus a productivity bonus tied to visits or units billed. That compensation structure is something your PEO administers as part of standard payroll, it doesn't require special handling beyond making sure the platform can run the pay structure you actually use. What it doesn't touch is the underlying billing and documentation compliance around those units, that's a separate clinical operations function neither Justworks nor Rippling is built to manage.

Two or three states of clinics, a productivity pay structure that's straightforward to run, and no in-house IT team may point to Justworks, which charges a per-employee fee; confirm with the vendor how it supports multi-state payroll before you commit. Scale to more states, or start standardizing EMR and scheduling software across locations, and Rippling's configuration tends to pay for itself instead.

The mistake worth avoiding is treating your state footprint as something you check once a year rather than something that updates as staffing changes. A therapist who starts covering a second clinic in a new state this month should trigger a payroll review this month, not at the next scheduled compliance check. Whoever schedules cross-clinic coverage should be looped into that trigger, since they're the one who sees it happening first, often weeks before it shows up anywhere else.

Picture a network that just acquired two independent clinics, one in a state it already operates in, one in a new state entirely. The first acquisition is straightforward, fold the acquired clinic's staff into your existing state payroll setup. The second isn't: every therapist at that new-state clinic needs a fresh payroll registration in a state you've never had staff in before, and depending on how the deal was structured, you may also be taking on staff who were previously paid through a completely different payroll system with its own quirks. Treat the new-state clinic as its own onboarding project, with its own timeline, rather than assuming it can be absorbed on the same schedule as the in-state one.

• Map every clinic and every therapist's primary and covering locations by state
• Confirm PT Compact privileges don't get mistaken for payroll registration
• Decide whether your productivity pay structure needs any special platform configuration
• Ask each vendor how quickly a new-state registration is handled when coverage patterns change
• Confirm how each vendor handles absorbing staff from an acquired clinic, not just a fresh hire

Health care and social assistance firms your size run payroll at roughly 39.7% of revenue¹, among the heaviest of any sector. A nonexecutive hire nationally takes a median 44 days to fill², worth building into how far ahead you plan clinic coverage when a therapist gives notice.
