How does it work?

  1. Invoice data is input directly into the e-Invoices Online web app or input into your software and sent to our cloud in .JSON form with 1 simple REST API.
  2. An e-invoice will appear in our service. The e-invoice can be managed and prepared for sending.
  3. It is then sent & delivered to the tax authority portal, then downloaded back to your software.
  4. E-invoices are safely archived in our legal archive for at least 10 years.*

*If you require e-invoicing ability for your software, but want to use your UI and storage, consider using the Transformation option.

Save months of 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.
