The use of another provider for e-invoicing, for example InExchange, should not be a problem.
To effectively process your invoice, regardless how the invoice is sent to us, the following information must be included:
- Reference: Name of the contact/purchaser
- Order number: Order / project number. If the invoice contains more projects, the order number is reported by rows.
Invoices received with incomplete information will be returned.
If you have any further questions, please contact us via telephone or e-mail firstname.lastname@example.org
