Scan the decision factors side by side
| Factor | Square | Shopify POS |
|---|---|---|
| Best starting fit | Simple in-person and mobile selling | Omnichannel retail |
| Ecommerce role | Available, but not always the center | Core platform strength |
| Payments | Square payments ecosystem | Shopify Payments or additional-fee considerations |
| Inventory depth | Good starter; advanced needs may add cost | Stronger when Shopify catalog is already primary |
| Main strength | Low-friction setup | Online/in-store continuity |
| Main risk | Outgrowing starter workflows | Paying for a larger stack than the shop needs |

Square is usually the cleaner starter for simple in-person selling; Shopify POS becomes more compelling when the Shopify online store is central to the business.
Processing rates, advanced inventory, staff permissions, hardware, add-ons, and ecommerce subscriptions can move the total far beyond the base POS fee.
