Payment apps and HIPAA: what each vendor says
6 tools compared. Checked 6 Nov 2026.
Vendors treat payment data differently from other patient data, and most say little about it. We report what they publish and offer no view on how HIPAA treats payment processing.
What to do
We don’t pick a winner here. Square is the only one with BAA terms we could find. Ask your compliance advisor how HIPAA applies to your payments.

- Confirm the BAA covers your exact plan and every feature you’ll use.
- Get the BAA signed before any patient data goes in.
- Turn on the settings the vendor requires, and train your staff on them.
This isn’t legal advice. A BAA is one requirement. Your clinic still has to set the tool up correctly and control who has access. Vendors change their terms, so confirm before you sign. PHI means protected health information, which includes patient data.
