Square vs Shopify POS: which is better in 2026?
The verdict
Square and Shopify POS both start small and scale, from opposite ends. Square is in-person first, with a free plan; Shopify is online first and the best system for retailers who sell in-store and on the web from one synced catalog. If you don't use Shopify Payments, Shopify adds 0.6 to 2% per transaction.
Choose Square if your sales are mostly in person and you want a free start. Choose Shopify POS if e-commerce is central and you want true omnichannel sync, and budget for the Shopify plan plus the third-party-processor fee if you don't use Shopify Payments.

Where each one wins
Square is the better pure in-person POS: free to start, faster to set up, and cheaper for a shop or café that rarely sells online. Shopify POS is unmatched when online matters, with one catalog, one inventory count and one customer list across web and counter. If you already run a Shopify store, adding Shopify POS is the obvious move; if you're in-person only, you're paying for omnichannel you won't use.
The processing catch
Square is locked to Square Payments at a flat rate. Shopify strongly prefers Shopify Payments and charges 0.6 to 2% extra per sale if you bring a third-party processor, a softer version of lock-in but a real one. Neither lets you shop processors freely the way an open system does.
