410: No permission to issue this invoice

The usual cause

Sending an invoice to KSeF requires the permission to issue it in the context of the business concerned. Check that the person, token or certificate used to sign in has that permission in the context chosen when signing in.

How to fix it

Have the permission to issue invoices granted in KSeF for that business, or sign in in the right context, then send the invoice again.
