While verification is pending, your configuration is saved and the submitted information is being reviewed. Full transmission of eligible invoices through Peppol becomes available once the representative’s identity and the company information have been confirmed.
What happens after activation?
Once your business has been verified, it is registered on the Peppol network through our approved service provider.
Eligible domestic B2B invoices can then be transmitted through Peppol when the customer’s business is also registered on the network and their EU VAT identification number has been provided.
You can monitor the status of each invoice from the dedicated dashboard. Please refer to the article:

What should you do if your registration is rejected or blocked?
First, check that the information entered for the business and its representative matches the submitted supporting documents exactly.
Also confirm that you uploaded the requested document types.
When an invoice cannot be transmitted through Peppol, check that the customer’s business is registered on the network and that its EU VAT identification number has been entered in the order.
