How to implement ERPNext to the official governmental e-invoice system

Dear All,

How to implement ERPNext to the official governmental e-invoice system ?
so we can submit invoice once ( on ERPNext and on the official e-invoice system of the Egyptian Finance government ) ?

Because we have to create invoice once again on the official website of Egyptian VAT system.

Any help would be much appreciated

Regards,

Hello, please check this eInvoicing

You might also need to check this Application Programming Interface (API) not sure which authority holds the einvoicing in Egypt.

Yes . This is the website we would like to implement EPRNEXT with.

Any idea how to link the teo invoice systems together ?

via API they already provided the documentation in the second link.
