1. Stripe
The developer's choice. Best subscription billing, invoicing, Connect (marketplaces), and documentation. Stripe Atlas for company formation. Default for SaaS and tech startups.
2. PayPal
Consumers trust PayPal at checkout — offering it can reduce cart abandonment by 10-15%. Weaker developer tools but unmatched brand recognition globally. Use alongside Stripe, not instead of.
3. Square
Unified online + in-person payments. Free POS hardware, inventory management, and online store. Lower in-person rates. Best for retail, food service, and hybrid businesses.
