What to do if the e-invoice went to the wrong company?
Short answer
Stop further sending, preserve evidence, contact both provider and wrong recipient, and assess accounting, contractual, and security remedies.
Do not send additional documents
First, determine whether it is a single document, a batch, or a systematic addressing error.
Save the status
Original XML, time of sending, EndpointID, delivery report and communication with the provider.
Accounting and security
The invoice may contain business or personal information, so address confidentiality, not just delivery.
Correct the master data
After incident, add Peppol ID, scheme, branch and partner check before sending.
