ERP Project Integration

We have an ERP project built with .NET MVC 5 and code-first MSSQL. In Turkey, it will work in integration with the Ministry of Health, and a drug tracking system (ITS), product tracking system (ÜTS), package transfer system (PTS) and farmazon (store integration) will be required. Integration should be about our own project models and also written on both the back and front, with a simple design for the user to see.
