Square and Clover figures from NerdWallet (updated February 6, 2026) and KORONA POS (April 2026). Shopify figures from Shopify's pricing page, checked October 9, 2026. Providers change prices; confirm before you buy.
Square: best for most small stores
Square is the lowest-risk way to start. The Free plan costs $0 a month, and you pay only card fees: 2.6% + 15¢ per in-person sale. There is no long-term contract, so you can leave any time. Start with an iPad and the $149 Stand, or the $799 Register for a dedicated counter setup.
Skip it if you process a high card volume and can negotiate lower rates elsewhere, or you need features Square doesn't support for your store type.

Clover: best all-in-one counter hardware
Clover is known for its hardware, from the $199 Clover Go reader to the $1,899 Station Duo with a customer-facing screen. Retail software plans run from $0 to $104.90 a month, with in-person rates of about 2.3% to 2.6% + 10¢.
Skip it if you don't want a long contract. Clover is often sold through banks and resellers, and promotional pricing may require a 3-year agreement. Ask about early termination fees in writing.

Shopify POS: best if you also sell online
Shopify POS keeps your counter and your online store on one product list and one inventory count. For a full store setup you need Shopify Basic ($29 a month billed yearly) plus POS Pro ($89 a month per location), so plan on about $118 a month. In-person rates on Basic are 2.6% + 10¢.
Skip it if you don't sell online. Square or Clover will cost less for a counter-only store.
