What They Offer
Hardware lineup
Square’s physical products range from the compact Square Reader for mobile payments to the full Register countertop system. Readers accept chip, swipe and contactless wallets; some devices include built-in receipt printers and card stands. Hardware is optimized for quick setup with the Square app and pairs with smartphones or iPads — useful for markets, craft fairs, home-based retailers and boutiques.
Point-of-sale systems
Square’s POS systems (Terminal, Stand, Register) combine payment acceptance with inventory, employee management and sales reporting. The software offers customizable item libraries, discounts, and multi-location management. Third-party integrations extend accounting and e-commerce capabilities, making Square a practical choice for independent home-and-garden stores, small cafés, and service providers who need both in-person and online sales channels.
Software & services
Square’s software suite covers online stores, invoicing, appointments, payroll and customer engagement tools. Merchants can launch a basic e-commerce site, send invoices, manage bookings and run loyalty programs from a single account.
