Square vs Shopify POS: which is better in 2026?
The verdict
Square and Shopify POS both start small and scale — but they're built from opposite ends. Square is in-person first with a genuinely free plan; Shopify is online first and is 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 0.6–2% 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 — just 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 — one catalog, one inventory count, 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 0.6–2% extra per sale if you bring a third-party processor — a softer version of lock-in, but a real one. Neither lets you freely shop processors the way an open system does.
Choose Square if…

- You don't need deep e-commerce
Choose Shopify POS if…
- You sell online and in-store
- You want one synced catalog and inventory
- You already use Shopify for e-commerce
- Omnichannel is core to your business

Which is cheaper, Square or Shopify POS?
Square for in-person-only selling, thanks to its free plan. Shopify POS can be better value if you also sell online, because it replaces a separate e-commerce platform — but factor in the Shopify subscription and the off-network processing fee.
