Compare
vs. Square
Square is one of the easiest ways to start selling. Here’s how Retailer OS compares on payments, inventory, accounting, and marketplaces as a store grows.

Square is one of the easiest ways to start taking payments, and its free plan can work well for a single register. It processes payments through its own service and offers more advanced retail tools on paid plans. Retailer OS is register-first too: card payments run on your own Stripe account, inventory and accounting come with every store, and Amazon and eBay are available as paid add-ons on the same catalog.
