I am trying to create a base that will store the following:

Purchased materials

Products made from said materials

Sales of the products

I’d like to track the costs of materials, costs of making the products, in stock/out of stock, etc. I’d also like to see the details of sales on different platforms e.g. eBay, Etsy, craft fairs, etc. I’d like to add to Purchased Materials from a form that has information like name, pack type, how many items in a pack, cost per unit etc.

I really appreciate any help you can give me.
