Square's own pricing page publishes three plans: Square Free at $0 per month, Square Plus at $49 per month per location, and Square Premium at $149 per month per location. Each plan carries its own card-present processing rate for tap, dip, or swipe payments: 2.6% + 15¢ on Free, 2.5% + 15¢ on Plus, and 2.4% + 15¢ on Premium. Square also states that businesses processing over $250,000 per year can talk to its team about custom pricing and processing rates.
Square sells its own hardware line, Handheld, Terminal, Register, Stand, and Kiosk, and also publishes software-only ways to take payments that need no added hardware, including Tap to Pay on iPhone and Tap to Pay on Android. Square's own site lists a wide range of named business types it serves, spanning food and beverage (coffee shops, quick service, full service, bars and breweries, food trucks), retail, and beauty and services concepts including hair salon, nail salon, barbershop, and day spa.
