Hello! One of the items I sell in my store are coasters. I sell them individually to wholesale accounts and in sets of 2, 4 and 6 on my retail website. When a customer purchases 2, is there a way to automatically deduct 2 from my inventory? Right now, when someone purchases 2, it just deducts 1 coaster, as it see's it as just 1 sale. And so on for if a customer purchases 4 or 6. I don't really use my inventory tracker all that much, because most of my items are made to order. However, we are starting to build back stock so this is something I want to stay more on top of. Thanks in advance!
