Stripe is a leading payment processor known for its developer-friendly API, transparent pricing, and comprehensive suite of payment solutions for businesses of all sizes.

Adyen is a global, enterprise-grade payments platform that unifies acquiring, processing, routing and risk management into a single stack for merchants with international and omnichannel needs.
Stripe for almost everyone; Adyen once you have the volume to negotiate and the channels to unify. Both publish their pricing, but they price differently: Stripe charges a flat 2.9% + $0.30 online and 2.7% + $0.05 in person, while Adyen passes interchange and scheme fees through at cost and adds $0.13 a transaction. Adyen's model is cheaper at scale, but it comes with a minimum monthly invoice, two months' notice to leave, terminal prices on request and an F at the BBB. Stripe has no minimum, no notice period, published hardware prices and an A+.
Better for startups, SaaS, marketplaces and any online business that wants published pricing, no minimums and a developer-first integration it can stand up this week.
Better for mid-market and enterprise retailers with real volume, in-store and online channels to unify, and a finance team that wants interchange and scheme fees itemised rather than bundled.
Stripe, unless you are large enough for Adyen to want you. The tables split cleanly. Stripe wins everything a small or mid-sized online business feels day to day: pricing you can read off a page, no minimum invoice, no notice period, hardware with a price tag, no separate Amex rate on the price list, and an A+ at the BBB. Adyen wins on the economics of volume: Interchange++ is cheaper than 2.9% on most card mixes, its ACH fee is a flat $0.40, and local acquiring in seven regions removes cross-border fees Stripe would charge you 1.5% for. The deciding question is whether you have the volume to make Adyen's model pay and the patience for an enterprise contract. Adyen's pricing page calls its fees indicative, the minimum invoice is disclosed only to sales, terminals are quoted on request and leaving takes two months' notice. That is normal for an enterprise acquirer and a poor fit for a business that wants to sign up this afternoon. Our grades reflect the same split: Stripe holds an A and Adyen an A-, with Adyen scoring higher on industry reputation and lower on support and contract terms.
Recommendations based on your business type
Stripe Billing, Invoicing, hosted checkout and the developer documentation are built for this, and there is no minimum invoice to justify. Adyen's model only starts paying off at volumes a startup does not have yet.

Adyen's unified commerce runs in-store terminals, e-commerce and marketplaces on one contract with one reconciliation, and Interchange++ plus local acquiring is where the savings compound at scale. This is the customer Adyen is built for.
Both. Stripe Connect and Adyen for Platforms both handle split payments, sub-merchant onboarding and payouts. Pick Connect if you want to ship quickly with published pricing; pick Adyen if you are already at enterprise volume and negotiating anyway.
Stripe Terminal has a $59 reader, a $299 smart reader and a published 2.7% + $0.05 rate. Adyen's terminals and card-present pricing are quoted by sales, and a single-location shop is unlikely to clear its minimum invoice comfortably.

Adyen acquires locally in Europe, North America, Brazil, Hong Kong, Australia, New Zealand and Singapore, which removes the cross-border fees Stripe charges 1.5% for. If most of your customers are abroad and the volume is there, the difference is material.
Neither. Both restrict prohibited categories and both close accounts on review with balances held. CBD, supplements, firearms, adult and similar categories need a specialist processor rather than either of these.
