How to send an e-invoice?
Short answer
The e-invoice is not sent as an ordinary e-mail attachment. The supplier creates a structured XML, the system validates it, the e-invoicing delivery-service provider searches for the recipient according to the participant identifier and delivers the document via Peppol or a designated delivery service. After sending, the status must be monitored: validation, lookup, transport, delivery, error or rejection.
ERP or application
An accounting document and XML will be created.
Check the rules
XSD, EN 16931, Peppol and Slovak rules.
Finding the recipient
The EndpointID and SMP will determine the destination mailer.
Proof of delivery
Confirmations, errors and retries are tracked.
Conclusion
Sending an e-invoice is a controlled process through validation, postman, lookup and status proofs; it's not just about sending a file.
