I would like to be able to upload a CSV to take inventory out of our system
ie I have 20 widgets in inventory
I sold 5 widgets off site without logging them in Shopify
I want to upload a file that says Widgets inventory -5
the inventory page in the main part of Shopify seems to just replace the inventory number. So if I import an inventory file with -5, it changes my inventory from 20 to -5
Any thoughts or suggestions welcome
