Enable the “Create Orders in Square POS” option to allow the app to create orders in your Square system each time a marketplace order is placed. Disabling this feature means the app won’t adjust the stock levels for your items, increasing the risk of overselling.

Step 4. Link existing products.

M2E Multichannel Connect will automatically match and link items from your connected marketplaces to your Square inventory using SKU or Product ID.

If no match is found, you can link the items manually. Simply click the View Not Linked Products button under the Link Products section.

You will be redirected to the Listings tab, where you can complete product linking. If your products aren’t linked, the app won’t be able to properly synchronize your inventory and orders.

Step 5. Synchronize products.

You need to enable synchronization for previously linked products to ensure your inventory remains up-to-date on marketplaces. Item sync provides automatic product data updates from your Square POS to Amazon, eBay, Walmart, TikTok Shop, and Kaufland.

To activate synchronization, click the View Not Synced Products button under the Synchronize Inventory section.

You will be redirected to the Listings tab, where you can turn on inventory synchronization for needed products individually or in bulk.

Once your products are linked and synchronized, your setup is complete. You can then manage product information and fulfill marketplace orders directly from your Square POS.

Step 6. List products on Channels.

With M2E Multichannel Connect, you can list linked and synced products from your Square POS on eBay, Amazon, or other marketplaces and expand your product range. Click on the corresponding button under the List New Items section and follow the instructions to create new listings.
