What is an Invoice Response for e-invoice?
Short answer
An Invoice Response is a structured message describing the invoice’s status in the recipient’s business process. Depending on the supported process, it may indicate that the invoice was received, is being processed, is queried, approved, rejected or paid.
Not just delivered
Invoice Response can talk about the business status of the invoice, not just the technical delivery.
Under query
The invoice can be questioned if the recipient needs clarification or correction.
Not always the end of the commitment
Peppol points out that the rejection of the invoice does not in itself cancel the existing payment obligation.
Partner support
Not every workflow automatically uses Invoice Response. You need to check the support with the provider and partner.
Conclusion: The Invoice Response is a useful layer for tracking the status of an invoice, but it does not replace an internal audit trail or an accounting assessment.
