If you have notice I have changed the title of the source code I have uploaded here. I felt that this website will grow more as the time pass by. I have included the language that the source code is uploaded.
In this way if somebody will upload a source code like Point of Sale for other language it will be categorize well.
The updated source code for POS and Inventory System can be found at http://www.sourcecodester.com/visual-basic/point-sale-software.html.
