Methodology
We used score = Σ (criterion_score × weight) with half-point cells rounded to one decimal. Evidence spans January 2025 through May 2026 across Reddit, G2, TrustRadius, X, Meta docs, Shopify blog, TechCrunch, Bloomberg, and CNBC. We weight developer velocity for ecommerce-led migrations but lift omnichannel when POS share is material. No vendor payments to this publication.
FAQ
Is Stripe better than Adyen for ecommerce?
Stripe launches faster for online-first teams; Adyen wins when in-person and online acquiring must sit on one interchange-plus contract at very large volume.
Why rank Braintree above Square for pure ecommerce?
Braintree’s PayPal wallet and split payouts help digital baskets; Square shines when hardware and ops tooling lead.
Do I still need Authorize.Net in 2026?
Keep it when your ISO bundle mandates it; fast D2C brands often graduate to API-first stacks unless compliance insists.
How should I handle Stripe account freezes?
Stage payouts, prep dispute evidence, and read community threads before high-ticket spikes.
Where does pricing diverge most at scale?
Blended stacks get costly at scale while interchange-plus grids favor Adyen- or Braintree-style processor links past roughly eight-figure annual card sales.
