Who is this best for?

This is the fastest way to decide whether Square is in the right neighborhood.

Best for
  • Retail businesses, restaurants, and service providers that need integrated in-person payment hardware (card readers, POS terminals, kitchen display systems) alongside online payment processing.
  • Small to mid-sized businesses that want a single system for inventory, sales reporting, appointments, payroll, and payments without multiple vendor integrations.
  • Food and beverage businesses where Square's restaurant-specific POS features (table management, menu management, tip handling, order routing) reduce the need for a separate restaurant management system.
Who should avoid
  • Heavy online/card-not-present volume (2.9% + 30¢ not competitive)
  • Frequently process manually keyed transactions (3.5% + 15¢ is expensive)
  • Need advanced API customization and developer tools
  • Require enterprise-grade fraud prevention and risk tools
  • Want lowest possible transaction fees through volume negotiations
  • Building custom checkout experiences requiring extensive APIs
