Make sure the product you want to stock is integrated between POS and WooCommerce. Whenever you want to control the inventory of products between the POS and WooCommerce. You have two options if you haven't integrated the product yet:

If the product is already integrated, there are two ways to synchronize inventory.

I. Automatic Synchronize

II. Manual Synchronize

If there are transactions in the POS such as Sell, Buy, Logistics, and Transfer Orders, the stock in WooCommerce will also move automatically. For example, I have a synchronized product White n Orange Shoes, the stock, for now, is still empty / 0.

We are moving to POS, and making a purchase transaction to add stock:

Click Pay, then OK.

Purchase Transaction is Complete :

Back to the Inventory menu at the marketplace.dealpos.app again, now you can refresh the page and check the stock :

As you can see, the product we just purchase before has been synchronized to WooCommerce, you also can crosscheck it by accessing the WooCommerce directly :

Manual sync is useful if there are stock differences between POS and WooCommerce. This manual sync will update WooCommerce stock to match the stock in the POS (Reference updates based on the stock in the POS). For example, there is a stock difference between POS and WooCommerce for White n Orange Shoes, POS 5pcs, and WooCommerce 10pcs.

Tick the product you want to update the stock manually, and click the Update button :

Stock back on Sync now :
