Status messages via Peppol

How the recipient automatically feeds back the invoice status: received, approved, paid.

Status messages are the mechanism through which the recipient of an invoice automatically feeds back the processing status to the sender. Via the Peppol network, the supplier receives a status message (Invoice Response) indicating whether the invoice has been received, is being processed, approved, or paid. eConnect has supported status messages since 2015.

How do status messages work?

The principle is straightforward: after receiving an e-invoice, the receiving organisation sends an Invoice Response back to the sender. This message contains a status code indicating the processing stage the invoice is in.

The Invoice Response message travels through the same Peppol network as the original invoice, but in the opposite direction. The sender receives the message automatically in their eConnect environment and sees the status appear alongside the relevant invoice.

Tip: to receive Invoice Response messages as a sender, your organisation must be registered for receiving Invoice Responses. This requires an SMP configuration with the capability invoiceResponse set to on.

Status codes

Every Invoice Response contains a status code indicating the processing stage. The statuses form a logical sequence, from initial receipt to full payment.

CodeStatusMeaningABAcknowledgedThe invoice has been received and is readable. This is the first confirmation that the invoice arrived correctly.IPIn ProcessThe invoice is being processed by the recipient. Assessment is still ongoing.UQUnder QueryThere is a question about the invoice. The recipient needs additional information from the supplier before processing can continue.CAConditionally AcceptedThe invoice has been conditionally accepted. There are minor points of attention, but the invoice is in principle approved.RERejectedThe invoice has been rejected. This is a final status. The recipient indicates that the invoice will not be processed. The supplier must take action, for example by sending a new invoice.APApprovedThe invoice has been approved and the next step is payment.PDFully PaidThe invoice has been fully paid. This is a final status.

The status codes RE (Rejected) and PD (Fully Paid) are final statuses: no further updates follow after these. The other statuses can succeed each other as processing progresses.

The following diagram shows how the statuses succeed each other, from initial receipt to the final statuses.

Clarification Reasons

With certain statuses (especially UQ and RE), the recipient can include a reason indicating why the invoice is being held or rejected.

Receiving status messages on the platform

When a recipient sends an Invoice Response, the status appears alongside the relevant invoice in your eConnect environment. The status change is normally communicated within three days of being updated by the recipient.

You receive status messages automatically, provided that:

  • Your organisation is registered for receiving Invoice Responses via the SMP
  • The recipient of your invoice supports the Invoice Response process

Not all recipients support status messages. It is a feature that is being adopted ever more broadly, but at present it is not yet universal.

The difference with MLS

In addition to Invoice Response, there is also Message Level Status (MLS). The difference is important:

  • Invoice Response (status messages) is a business-level message. It is sent by the receiving organisation (Corner 4) and concerns the substantive processing of the invoice: has it been approved, rejected, paid?
  • MLS is a transport-level message. It is sent by the receiving Access Point (Corner 3) and concerns the technical delivery: was the document successfully delivered to the recipient?

Both message types complement each other. MLS tells you whether the invoice has arrived technically, Invoice Response tells you what the recipient does with it.
