What is the Shopify + Shopify POS integration

Running Shopify online and a physical store sounds simple until inventory and customer data start drifting. One return processed in-store can throw off stock online. A staff member can’t see loyalty history at checkout. Then you spend evenings reconciling reports that still don’t match. The Shopify POS integration connects your Shopify store with Shopify POS so key commerce data is handled as one operation across channels. It keeps product and inventory changes aligned, routes orders and refunds through consistent records, and makes store activity visible in the same place you manage online. This setup fits teams selling both in-store and online who need one workflow for stock, orders, and customers.

How the Shopify Shopify POS integration works technically

• Shopify Admin and Shopify POS share the same Shopify catalog, with product variants, prices, and SKU-level inventory represented as unified records.

• Inventory quantities are adjusted from POS sales, online orders, returns, and manual stock corrections, with updates propagated per location in Shopify.

• Orders created in Shopify POS are written as Shopify orders, preserving line items, taxes, discounts, payments, and fulfillment status for consistent reporting.

• Refunds and exchanges processed in POS are recorded against the original order, with inventory restock and payment adjustments reflected in Shopify.

• Customer profiles created or updated at POS are synced to Shopify customers, mapping identifiers, contact details, and address data.

• Register and location context is logged on POS-originated transactions to support channel attribution, auditing, and reconciliation.
