Strengths and weaknesses
- +Native, one-integration access to PayPal and Venmo alongside normal card processing, a capability no non-PayPal gateway can match
- +Single vault and one API across cards, PayPal, Venmo, Apple Pay, Google Pay, ACH and local methods
- +Developer experience widely praised: clean SDKs, drop-in UI, strong sandbox, easy integration
- –Weak, slow customer support, phone support removed, form-only help is a top complaint across review sites
- –Shares PayPal's reputation for frozen funds, held disbursements and opaque risk/account decisions
- –January 2025 price increase moved Advanced Credit/Debit from 2.59% to 2.89% + $0.29
- +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
