How does it work?
- Data (from your software) is taken and .JSON file is created and send 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.
- e-Invoice is kept on our server for 48h, before being deleted. It can be edited inside of your account. (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.

Use cases
Invoicing provider
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 provider
You provide a comprehensive service that has a large overlap with the requirements of a full e-Invoicing system. 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 service by adding our e-Invoicing component to your existing infrastructure.
Custom
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 have a software for accountants that is serving them completely but your software is lacking the e-invoicing functionality. Keep focusing on providing the best solution for accountants but let the e-invoicing legislation to us. Integrate in days instead of lengthy development.
