Inventory System using Python with Bill Receipt

The Bill print Inventory is developed by python tkinter.Inventory is most an important part in any shop for calculation the sales.  The project is built to manage  items and transactions. To make a new transaction, fields such as: Fried rice name, qty and payment needs to be selected. If you like to learn point of sales systems step by step, this is the right place to learn from the beginning.

after calculating the total Print receipt will be released.

I have attached the video tutorial below it will help you  to do this  step by step.
