A monthly fee does not reveal whether a payment provider fits your system. Compare real scenarios: first payment, failed payment, payment link, returning customer, partial refund, instalments, void, and receipt reference.
For every scenario, ask for documented answers: what the request sends, what returns in response, whether a test environment exists, how status changes are delivered, and which rate and permission rules apply. “The API can do it” without a document or example is not acceptance criteria.
Check the exit path too: can you export transaction report and identifiers, retain invoice reconciliation, and continue operating if your system changes provider? This is not a price comparison. It is a comparison of ability to run a complete workflow.
Verification
API documentation, business-route terms, and acquiring agreement for every provider.
