Shopify POS and Online Inventory Mismatch

POS and online inventory not matching? Learn how to sync Shopify POS inventory with your online store to prevent overselling and counting errors.

The POS-Online Disconnect

You sell 5 units in your retail store via Shopify POS. But your online store still shows 10 in stock. An online customer orders 8 — but you only have 5 left. Now you have a cancelled order and an angry customer.

POS-online inventory mismatch is one of the most common problems for merchants selling both in-store and online.

The Fix: Real-Time Sync

PODesk receives inventory through Shopify's APIs, which sync with POS. When POS sells, inventory updates. When PODesk receives a PO, both POS and online show correct counts.
