Group products stock, need help
I have a question because this is my situation, I have an e-commerce store and an ebay store. I am selling the products separately in these two stores and I want to unify it in order to control the stock of everything. The problem is that I sell the products by brand, that is, I have product A and it is valid for brands X, Y, Z but I need product stock A, I have been talking about connectors for ebay and ecommerce but I need to know if I have to treat the product A separately by brands and then there is some way to group the stock in odoo or if I have to treat the product as one when referencing it through the SKU. Can someone help me with this? Thank you all very much in advance.
