Payment Gateway / PSP
Checkout.com vs Square
Checkout.com and Square both show up under the payment gateway category, but they solve slightly different jobs. Checkout.com uses usage-based from custom pricing, while Square runs on subscription from $30/mo with free tier. Both sit at moderate lock-in. Transparency lands at 4/5 versus 5/5. Both tools target SaaS with online payments, so the choice comes down to pricing, lock-in, and operational fit rather than scope. Worth noting: Checkout.com is explicitly not for offline, Internal projects. The honest trade-off: Checkout.com trades off on offline-only retail; Square trades off on offline-only retail. On the plus side, Checkout.com highlights SaaS with online payments. Checkout.com's documentation also calls out e-commerce checkout. For teams evaluating payment gateway options today, the decision usually hinges on whether Checkout.com's profile or Square's profile maps more cleanly to the pricing model, lock-in tolerance, and scale your team can live with. Beyond the headline pitch, a documented Checkout.com use-case is "E-commerce checkout", and a documented Square use-case is "E-commerce checkout".
Quick take
Checkout.com is for SaaS with online payments; Square is for SaaS with online payments; decide on pricing model.
