Which Should You Choose?

Stripe is the dominant choice for online businesses, SaaS companies, and developer-led startups. Its API is the gold standard for programmatic payment processing, subscription billing, and marketplace payments. If your business exists primarily online and you need maximum flexibility, Stripe is unmatched.

Square is the top choice for brick-and-mortar businesses — retail, restaurants, coffee shops, and service providers. The free POS software, affordable hardware terminals, and built-in tools (appointments, payroll, inventory) create an all-in-one ecosystem that's turnkey from day one.

The businesses are complementary: Stripe for online-native companies, Square for in-person commerce. Omnichannel businesses (e.g., retail with an online store) may benefit from using both — Stripe for web/mobile payments and Square for in-store POS.
