Strengths and weaknesses
- +Single API and account unifies online, in-app, and in-person (omnichannel) payments
- +Transparent flat-rate pricing with no monthly fee, PCI fee, or minimums on the free tier
- +Broad payment-method support: cards, Apple/Google/Cash App Pay, ACH, Afterpay, gift cards
- –Risk-driven account freezes and fund holds with little notice are a recurring, serious complaint
- –Phone support limited to first 90 days; slow, hard-to-escalate help for complex issues
- –Flat-rate pricing becomes expensive at high volume versus interchange-plus processors
- +Best-in-class developer experience: clean versioned REST API, idempotency keys, webhooks, and full-parity test/sandbox mode
- +Documentation is an industry gold standard, interactive API reference with per-language snippets
- +First-party SDKs for every major server language plus mobile/JS clients, minimizing boilerplate
- –Flat 2.9% + 30¢ rate is expensive for low-ticket and high-volume merchants vs. negotiated interchange-plus
- –Costs stack quickly: +1.5% international cards, +1% currency conversion, $15 disputes, plus add-on product fees (Billing 0.7%, Tax 0.5%)
- –Risk engine can freeze funds or terminate accounts abruptly with opaque explanations
