I need to solve this project, is basic Python programming 

An establishment that is dedicated to the sale of products, needs to always have its inventory updated in order to provide quality service to customers. On the other hand, the company administrator needs to have information about the vendors and the sales made by each of them.
For both the sellers and the administrator, it is very important to have this information at hand in a simple and practical way through an application, so that it can be consulted at the time it is required.
 How can you help an establishment like the one described? Can you propose a program that solves this need? What options would the program have? What information would you keep? In what format?
