Resend an invoice

How to resend a previously sent invoice, including to fill in an empty order number.

Resending a previously sent invoice can be necessary when delivery failed, the recipient's EndpointID was incorrect, or a reference (such as an order number) needs to be corrected. On the eConnect platform you can do this from the Outbox.

How do you resend an invoice?
Step 1: Open the invoice in the Outbox

Go to the Outbox and click the invoice you want to resend.

Step 2: Click Resend

In the invoice details, click Resend.

Step 3: Check and adjust

Check the details. Before sending you can still change fields, such as the recipient's EndpointID (Peppol address) or the reference (order number, PO number).

Step 4: Send again

Click Send. The invoice is sent again with the same invoice number. The platform records that this is a resend.

When is resending the right choice?

Resending is the right action in these situations:

  • Delivery failed: the recipient could not be reached via Peppol (for example because of a wrong EndpointID or a technical problem on the receiving side).
  • Reference error: the recipient rejected the invoice because of a wrong order number or PO number. When resending you can correct the reference without creating a new invoice.
  • Recipient was temporarily not registered: the recipient now has an active Peppol registration and the invoice can be delivered.

Resending is not the right choice if the invoice content itself is wrong (wrong amount, wrong recipient). In that case, first send a credit note and then create a new invoice.

Correcting the EndpointID

If delivery failed because of an incorrect Peppol address, you can change the EndpointID when resending. Check the recipient's correct Chamber of Commerce number or OIN. For government organisations the OIN must always contain exactly 20 digits, including leading zeros.

Frequently asked questions
Can I change the reference or order number when resending?

Yes. Before you actually resend, you can still change fields such as the reference (PO number, OrderReference). The invoice is then sent again with the same invoice number but with the corrected reference. This saves the credit-and-new-invoice route.

When is resending needed?

The most common reasons: delivery failed (error in the Peppol address), the recipient rejected the invoice because of a wrong order number, or there was a temporary outage at the receiving party. You can then offer the invoice again, optionally with corrected details.

Is the invoice resent with the same invoice number?

Yes. The invoice keeps the same invoice number. Only the fields you changed (such as the reference or the EndpointID) are updated. The recipient receives the invoice as a new delivery.
