Products: Internal Consumption / Inventory / Professional Use
Are you able to link the pos to a product inventory and also consumption inventory.
When a service is created you could add an option for products used and amount used so that this can be deducted from the products in the consumption inventory when the sale is made/appt completed. Same goes for when a product sale is made, this should be deducted from the inventory.
Easily manage non-retail product use / Set product types as Retail, Internal or both / Track disposables / Deduct without editing product type
