Square combines in-person and online payment processing with a full suite of mobile, retail and online sales and business management tools in one streamlined package. There are no startup or monthly fees to access all that Square offers, either. For most users, the only costs of using Square are its transparent, flat-rate payment processing fees.

Square helps all sizes and types of businesses to accept contactless payments, including all major credit and debit cards and mobile payments. With Square you can do all the things you need to help run and grow your business – from keeping track of inventory, to managing staff rosters, taking appointment bookings and more.

Square uses mobile technology to allow businesses (or artists or vendors or just about anyone) to accept credit card payments from their smartphones or tablets no matter where they are.

How Does Square Work? Square starts with simple, flat-rate payment processing that includes credit cards, contactless payments, and ACH transfers. Then, it offers various products within its ecosystem that all work together to form a complete small business management solution. However, some solutions, like Payroll, can stand alone.
