We have added support for the BT-158 field (Classification code value) — a required field for electronic invoices submitted to Greek public authorities via PEPPOL.
This field is used to specify a classification code (such as a CPV code) related to the invoiced item or service. It is now available in the Invoice Line Items section under the “Full” tab.
Where to find it:
When editing an invoice, scroll down to the line items table, open the Full view for a line, and enter the code in the “Classification code value (BT-158)” field.
Why it’s important:
Certain Greek authorities require this field for validating public procurement invoices. Adding BT-158 ensures compliance with national B2G rules.
If you need assistance entering this value or mapping classification codes, feel free to contact our support team.
