I would like to have an Intermediary stock so that the system calculate the difference between the intermediary stock and sales to give me every day the difference which is the left over.
I bake 50 croissants ( +50 croissants in stock ). Then I take 50 croissants to be sold in the front store ( - 50 in stock ). My cashier sell 25 only and I have 25 left over ( this isn’t in stock anymore).

How to import all the sku barcodes from Usfood which is our main supplier for the goods before transformation ( flower, butter, milk).
Then we will use these ingredients to bake some croissants with an other barcode.
How can we integrate our own barcode with the sku barcodes of our suppliers?
