Serial numbers and lots creation¶
If a tracked product is available in your POS, adding the product to the cart opens a pop-up window where you can type or scan the product’s serial or lot numbers. To add more than one of the same tracked products, click on enter to validate and start a new line.

Note
Changing a tracked product’s quantity using the numpad turns the list-view button red. Click on it to add the missing lot and serial numbers.
Lot & Serial Number(s) are required on tracked products but not mandatory. Meaning that not attributing some or any does not prevent from completing the sale.
