I need to check the prices of the same product bought from different supplier. But they are quit a lot and it’s too hard to do it manually. For example , I run a bar and I have to compare prices of vodka’s GIn’s and etc from 3 or 4 different suppliers. And after that; I have to make sure that the price they sold me the vodka is the one we have agreed on.
This is generally done by purchase orders. You issue purchase order to supplier (Purchase Orders tab), then when you receive purchase invoice from supplier, you can check if amounts on invoice are the same as on the order.
