this inventory is developed using python3.2 tkinter, and sqlite3. you can make invoices for a shop using this software. you need python3.2 to run this. no more modules are required since tkinter and sqlite3 were in python3.2 windows package.
I am seeking to build a database management application using Python 3, Tkinter and SQLite and this is the first application example I have seen yet that is similar to my goals. Thank you for your work on this and for sharing it.
