How should e-invoice be archived after payment?
Short answer
After payment, retain the original XML, attachments, a readable rendering, the validation report, accounting export, the link to the payment, payment status and the processing audit trail. Payment does not replace or shorten the obligation to preserve the invoice record.
XML and Annexes
The original XML remains the base file even after payment.
Bond to the bank
Save payment status, date, amount, account and matching characters.
Export and accounting
The archive should show to which accounting record the document was transferred.
Timeline
Acceptance, validation, approval, payment and archiving should be in one track.
Conclusion: once paid, the invoice does not disappear from the workflow. It becomes an auditable evidence package.
