If an e-invoice fails to deliver, first check whether Shine was able to send it successfully.

Open the invoice under Invoices, then select History on the right-hand side.

Below are the most common reasons for failed e-invoice delivery.

1. Incorrect or invalid e-invoice address

Ensure your customer’s e-invoice address is correct and that the correct format (VAT, GLN, DUNS, OVT, etc.) is selected in the customer profile.

2. Character limits

Customer company name

Maximum length: 80 characters.

This limit is defined by standard XML invoice formats used by all operators.
If the limit is exceeded, the operator rejects the invoice.
(The XML file is the machine-readable version of the invoice.)

Message field

The message field is limited to 1024 characters.
Exceeding this limit will cause the delivery to fail.

3. Missing or incorrect customer requirements

Some customers require specific information such as PO number, buyer reference or payment reference.
If these are missing or incorrect, the receiving operator may reject the invoice.

4. Routing issues

E-invoices pass through several operators.

If routing rules or accepted formats are not aligned between providers, the invoice cannot be delivered.

5. Unsupported attachment format

Only PDF attachments are supported for e-invoices.
Other file formats will result in a failed delivery.
