Square

Square (from Block) reshaped how small businesses take payments, turning a phone or tablet into a full point-of-sale and commerce system. Beyond payments it now spans a whole operations suite — and it has added Square AI, a named assistant that lets merchants ask questions about their business in plain language and get insights from their own sales data. For businesses that want approachable commerce tools with genuine AI-driven insight, Square is a strong, well-established choice.

What is Square?

Square, a business of Block, is a commerce and financial-services platform serving businesses from solo sellers to larger operations. Its foundation is payment processing and point of sale — card readers, registers, and software that let businesses accept payments in person and online — extended into a broad ecosystem: online store building, invoicing, appointments and bookings, inventory management, payroll, banking and loans, customer engagement and loyalty, and analytics. Its AI shows up most visibly as Square AI, a named assistant that lets merchants ask questions about their business in natural language — sales trends, best-selling items, busy periods, comparisons over time — and get answers and insights drawn from their own Square data, making analytics accessible without building reports manually. Square also applies machine learning across areas like risk and fraud, and has been expanding AI-driven features across its products. Its appeal is an integrated, approachable platform where payments, operations, and now AI insights live together. Accounts are free to open, with transaction and hardware/software fees. It serves retail, restaurants, services, and more.
