Quadru connects your Shopify store with Square. Browse your Square Item Library in the Shopify admin, compare catalogs side by side, and match products by SKU. Import Square items singly or in bulk. Get SKU suggestions in your store's own naming style, in-app or through Sidekick. Link one Shopify location with one Square location, choose which side wins when counts disagree, and turn on two-way inventory sync. Sync moves counts only. Products, prices, and images are never changed automatically.

• Two-way inventory sync between one Shopify location and one Square location
• You choose the primary source: Shopify or Square wins when counts disagree
• Browse your Square Item Library, compare by SKU, and import items as drafts
• SKU suggestions that follow your store's naming style, in-app or via Sidekick
• Syncs inventory counts only. Never adds, edits, or removes products
