Square: point of sale for growing businesses.
Overview
Square is an all-in-one point-of-sale system that bundles hardware, software, and payment processing into a single account, making it one of the fastest ways for a small business to start accepting payments in person and online. Rather than sourcing a terminal from one vendor, checkout software from another, and a payment processor from a third, Square brings all of it under one roof — a business can order a reader or countertop terminal, download the app, and be taking payments the same day.
Key features
Beyond core checkout, Square includes inventory tracking, invoicing, a basic CRM, and an online store builder, giving small businesses tools that would otherwise require several separate subscriptions. It also offers industry-specific software for restaurants and retail, covering table management, kitchen display tickets, and product catalogs. For businesses that sell both in person and online, Square unifies both channels in one dashboard, so sales, inventory, and customer data stay in sync without manual reconciliation.
Who it's best for
Square tends to work best for single-location small businesses and solo operators, while multi-location enterprises with complex integration needs often outgrow its all-in-one model.
