Hi there, before i buy the plug in i would like to clear a few questions i have to be sure is what im looking for. I can see the “add stock” meta box in every “edit product” menu, but i can’t find it in the variable-products , it only allows me to introduce a “cost” either in de General descrpition or in an especific variation, but how will I be able to add inventory when I buy more merchandise to average existing merchandise and incoming merchandise to correctly get the profit margin? and if that’s not the right way to add inventory every time i buy new merch, how should i do it? Thanks for answering !
