Coming soon!

How does it work?
- Data (from your software) is taken, then a .JSON file is created and sent to e-Invoices Online by calling 1 simple REST API
- e-Invoices Online transforms the received data into a detailed e-invoice
- The e-invoice can be sent to SEF and/or (automatically) downloaded.
-
The e-invoice is kept on our server for 48h, before being
deleted. It can be edited inside your account.
Need long term archiving?*
*All invoices are legally required to be archived for a determined number of years (differs between countries). Should you wish to have the legal archive included in your package, consider taking the Integrator package.
Save months on development time
Use cases
Invoicing software
You have put a great deal of time and effort into developing your invoicing software and building a customer base. Now, there is a new government-imposed e-invoicing requirement that would take you more time and effort to develop. Save your time and money for more important matters, and let us provide you with the e-invoicing component you’re missing.
DMS or EDI software
You provide a comprehensive program that has a large overlap with the requirements for e-invoicing softwares. The document exchange and archiving are key aspects to both services. You likely have clients that would benefit greatly from e-invoicing. So rather than them seeking this service elsewhere, upgrade your program by adding our e-invoicing component to your existing infrastructure.
Developing your own software
You are looking to develop a service/product that includes e-invoicing, but wish to maintain full control of your customers’ experience throughout your service. Instead of redirecting your clients to an external e-invoicing service, the Transformer package allows you to use our service as a hidden partner. Your software can rely on our service, all while never being seen by the customer.
Accounting software
You provide a complete software for accountants, but your software lacks e-invoicing ability. Using our transformation APIs, you can keep focusing on providing the best solution for accountants, and leave the e-invoicing legislation and data transformation to us. Integrate in just days instead of a lengthy development cycle.
