Frequently asked questions
How do you score payment platforms?
Each comparison evaluates both platforms across 12 ISV-critical criteria: integration architecture, API and developer experience, PayFac options, pricing transparency, onboarding, payouts, global reach, fraud and risk tooling, reporting, hardware and in-person, compliance coverage, and platform maturity. Scores are 0–10 based on public documentation, API testing, and production behavior — not vendor interviews.
Are these comparisons independent? Who pays you?
Comparisons are independent. We do not accept commission or affiliate payments tied to platform selection, and we do not interview vendors before publishing. The site is funded by advisory engagements with ISVs — buyers, not sellers. If a platform updates a feature that changes a score, we update the page and note the change.
How often are scores updated?
Platforms ship changes constantly, so we re-score a comparison whenever a scored feature materially changes — new API surface, new pricing model, new geo coverage, deprecated endpoints. At minimum, every comparison is reviewed quarterly. The Updated date on each page reflects the last substantive change, not a cosmetic edit.
What if the provider I use isn't listed?
The current set covers the 18 most-requested platforms across US and EU ISVs. If the one you're evaluating isn't here yet, send us the name via the contact form — we prioritize additions based on request volume. Meanwhile, the criteria themselves are portable; you can apply them to any candidate using the methodology page.
Can I request a comparison for my specific stack?
Yes. A custom comparison takes your actual integration constraints — existing auth flows, ledger system, payout schedule, compliance footprint, volume tier — and scores candidates against those instead of the generic 12. Turnaround is typically 3–5 business days. Request via the contact form with a short description of your stack.
How is this different from Gartner or G2 reviews?
G2 and Gartner aggregate buyer sentiment, which is useful signal but dominated by merchant-side reviewers — not ISVs embedding payments. Our comparisons are written specifically for the technical and commercial decisions ISVs face: PayFac vs referral, custom onboarding, split payouts, platform liability. Different audience, different criteria, different conclusions.
