Strengths and weaknesses
- +Interchange++ pricing gives full transparency into interchange, scheme fees, and the processor's margin
- +Intelligent Acceptance AI measurably lifts authorization rates (reported up to +9.5pp in beta; +1.9% for NordVPN)
- +Strong global coverage of card schemes plus local payment methods, wallets, and bank transfers
- –No publicly published rates; pricing is entirely quote-based and requires contacting sales
- –Integration can feel technical and benefits from dedicated developer resources
- –Support can be slower than expected for smaller or lower-priority issues
- +Transparent blended pricing with no setup, monthly minimum or cancellation fees on the standard online product, you pay only on successful transactions
- +Excellent European payment-method coverage out of the box (iDEAL, Bancontact, Klarna, SEPA, PayPal, Apple/Google Pay, 40+ methods)
- +Clean, well-documented REST API with reliable webhooks and strong recurring/subscription handling that developers praise
- –Recurring, serious merchant complaints about sudden account holds, collateral reserves and frozen funds with poor communication (reflected in a low 3.2/5 Capterra score)
- –Settlement/payout timing in practice can lag the documented ~5 business days, with reports of cards taking 2–3 weeks and Klarna up to two months in disputed cases
- –Europe-centric: weaker fit than Stripe/Adyen for US-first or truly global expansion
