The challenge

When the team started the development, the General Department of Taxation (GDT) was not not publishing a standard for e-Invoices generation.

The solution of Sinvoice had to be designed enough flexible to support the current needs but also to integrate with external softwares and GDT system in the future.

SInvoice can process billions of invoices per year, and it can can be scaled out without down time.
