i was asked to make a system for shop which use barcode to identify goods.
problem i have is
the owner buys goods lets say a soap, he buys same brand soap from one dealer a price of 10$ then he buys same brand from another dealer for 12$
but this brand has one barcode.
so when generating a report regarding profits etc.. report will not 100% accurate due to those prices.
what is the way to solve this?
