In integrating the marketplace in DealPOS, there are several cases for users who have run the marketplace first to sell (the product data already exists in the marketplace). So for cases like this, you don't need to add Product Data to POS manually, you can download Data Products in the marketplace to POS by accessing the Not in POS tab on the Product menu at marketplace.dealpos.app.
On the Not in POS page, All products in the marketplace but not yet on DealPOS will appear on this page, the first thing you have to do is click the Scan button, then the products in the marketplace can be mapped with DealPOS based on SKU.

You don't need to add manuals for products that are not in this POS, you can immediately download the product so that it is entered into DealPOS automatically.
*Note: Make sure every product in the marketplace has its SKU filled.
