Hi Maine1,
From the way that you have described that behaviour, it sounds like you have your products set up as Inventory items, when they could instead be set up as Non-Inventory items, which would remove the requirement to track stock-on-hand. Unfortunately, once a product has been created as an Inventory item it isn't possible to switch it to a non-inventory item - in this case, your best bet would probably be to make that Inventory item inactive, and then create a new product to represent those items in your system moving forward. You can take a look at this article for further information on how to handle the existing Inventory item, and then this article for how to set up the new non-inventory item. If you have any other questions, feel free to reply in this thread or reach out to our support team on 1800 046 038 if you want to go through it in more detail with a member of our support team over the phone.
