Alternatives to Square

PayPal Commerce Platform
Decision brief →
Same problem / SMB payments

PayPal covers the basic online payment acceptance use case at comparable processing fees but lacks Square's POS hardware, inventory management, and restaurant/retail vertical features. Better when the business is primarily online with no physical retail component.

Step-up / developer-first payments

Stripe is the step-up for online-first businesses where API flexibility, subscription billing, and ecosystem integrations matter more than POS hardware and retail inventory tools. Square's online payment capabilities are adequate but not developer-first.

Braintree
Decision brief →
Step-sideways / PayPal ecosystem

Braintree offers volume-based rate negotiation and PayPal native integration that Square doesn't provide. Better for businesses that have outgrown Square's flat-rate pricing and need custom processing rates at higher volume.

Authorize.Net
Decision brief →
Step-sideways / legacy gateway

Authorize.Net is the alternative for established businesses using legacy POS systems or merchant accounts that need a payment gateway overlay rather than a full POS replacement. Less modern than Square but compatible with existing hardware infrastructure.
