How to choose
If your budget is under $50/month, Square's Plus plan ($49/month) is the only viable option with advanced features; Lightspeed starts at $109/month and Shopify POS Pro is $89/month.
If you manage thousands of SKUs or variants, choose Lightspeed Retail for its automated reorder points and cross-store transfers; Square's advanced inventory requires the paid plan and is less robust for complex catalogs.
If you sell online and in-store, Shopify POS is the only option that syncs inventory and customer data in real time across channels; Square and Lightspeed require separate e-commerce integrations.
If your card sales exceed $15K/month, Square's flat-rate processing (2.6% + 15¢) becomes expensive; compare against Lightspeed's custom rates or Shopify's 2.5–2.7% in-person fees.
Our verdict
Square POS is the best overall choice for most small retail businesses due to its $0 entry cost and robust offline mode, while Lightspeed Retail is the superior choice for complex, high-SKU specialty retailers willing to pay $109+/month for advanced inventory controls.
