All existing Peppol registrations and settings will be automatically migrated from ZRE to OZG-RE. No action is required from invoice issuers.

How do I send invoices via OZG-RE?
There are four options:
- By registering in the OZG-RE portal and manually creating your invoice via the web submission portal.
- By registering in the OZG-RE portal and manually uploading a previously created XRechnung file via the OZG-RE portal.
- You can log in to the OZG-RE portal and send your upload (as an XRechnung file) via email.
- You can submit your invoice via the PEPPOL network (OZG-RE registration not required).
What is the best option for sending invoices via OZG-RE?
Well, the OZG-RE web portal is free and very easy to use if you only have a small number of invoices to send.
However, if you have a large number of invoices to process, it can be quite time-consuming to process them all manually via OZG-RE.
If you have a large number of invoices, we recommend using an invoicing solution like Invoice-Portal. With a solution like Invoice-Portal, you can quickly and easily upload, convert, and send numerous invoices directly to the OZG-RE Portal. All this can be done directly from the software.
All you have to do is:
1. Send your invoice as an XRechnung:
2. And send it by email:
How do I know that my invoice has been received in OZG-RE?
You can check the status of all invoices you have submitted within the OZG-RE portal (provided you are registered).
You can find this information under the “Processing status of submitted X-Invoices” portal tab.
Who uses OZG-RE?
