SKU IQ review

SKU IQ answers a common situation: the shop already runs Square or Clover, and the owner wants the Shopify store to stop overselling. It is not a point of sale; its Shopify App Store listing describes it as a sync for inventory, orders and the product catalog between Shopify and Clover, Square or Lightspeed Retail, with a dashboard of sales, orders and sync events and detailed logs. Pricing scales with how much you sync. Basic at $19 a month syncs quantities only, Plus at $49 syncs most product attributes and Pro at $99 syncs all product attributes and images, each with a 14-day free trial. That makes SKU IQ the cheapest way to connect an existing register to Shopify, but the total cost includes the POS subscription and card fees you already pay. Merchants starting fresh are usually better served by Shopify POS or a POS with a built-in Shopify integration, since two systems mean two catalogs to keep tidy.
