Payment Processing
The payment processing landscape reveals clear market stratification: Stripe Terminal and PayPal lead with 69% and 65% shortlist rates respectively, followed closely by Square at 61%. Mid-tier players like Adyen and Checkout.com cluster around 45-49%, while specialized solutions like Chargebee and QuickBooks occupy the 35-41% range. All top brands achieve maximum model diversity (4), indicating broad recognition across evaluation frameworks. However, the complete absence of prompt coverage means these rankings reflect evaluator assessment patterns rather than actual user demand signals.
