Modify the Pos(point of sales) project in Vb.net c#

Job Description:

The project is written in C# (Microsoft Visual Studio 2013 or Its later version) as front end , Microsoft SQL Server database as back end with Crystal Reports.

I would like to make some modifications to the program

1- The product number (or any way to protect the program from copying on multiple computers). The goal is to activate the product on one or two computers so that the program does not work when copied by the customer to another computer.

2- Print invoices after the sale process via a thermal printer with a printer selection page and print paper settings

3- Modify the barcode printing page and make it possible to choose page dimensions and printer type

3- Adding the feature of selling by installments (payment in stages, such as every month or date, when the customer pays part of the amount)

4- Alerts about expiry or quantity

5- Amending the return of purchases (when returning purchases, the program adds the materials to the store, and the correct ones must remove them from the store)

Навыки: Программирование на C#, .NET, SQL, SQL-сервер Microsoft, VB.NET
