# Choose your integration

your stack, then follow its setup guide. Most merchants are live within a day.

## Payment integrations

Customers pay with HSA/FSA funds directly at your checkout.

## Post-purchase reimbursements

Customers pay as usual, then qualify afterward and get reimbursed from their
HSA/FSA. No checkout changes needed — this also works for in-person sales.
