What is Square?
Square is a point-of-sale and payments platform for businesses that take card payments in person.
What does it do?
Processes cards through its own readers, terminals and register hardware, with a POS app for items, tabs and receipts. Also handles invoices, online checkout, gift cards and customer records.
Who is it for?
Retail shops, cafes, restaurants and mobile sellers who want hardware and software from one vendor. Less suited to purely digital businesses selling subscriptions or downloads.
What are the alternatives to Square?
SumUp and Zettle are lighter card-reader-first options for small in-person sellers. Lemon Squeezy is a different shape entirely: checkout and merchant-of-record billing for digital products.
