Upon submission specific technical criteria (e.g. file format, mandatory fields, etc.) are validated.
If the result is positive a registration confirmation is shown for invoices uploaded and entered in the online form. If the web service or PEPPOL interface is used a positive reply message will be sent immediately.
In case of an error the system immediately gives negative feedback. In this case the e-Invoice is considered as not submitted, no email is sent out and no web service callback is initiated.
After a positive technical validation the receiving system validates further prerequisites (e.g. correctness of the reference data regarding the order and the invoice recipient).
If the e-Invoice is correct both technically and content-wise, a PDF is generated and forwarded to the stated recipient. An email or web service callback with the PDF of the e-Invoice attached informs the biller that the e-Invoice has been accepted.
If the content validation shows any errors, the biller is informed of the reasons by email or web service callback. In such cases, the invoice is considered as not submitted and no PDF is sent out.
Calculation of the due date
The receipt of the invoice is recorded with an electronically generated receipt time stamp and displayed on the PDF document. Based on this date the payment terms are calculated according to the stated payment conditions.
If any questions or errors occur contracting partners may contact the person in charge of the invoice recipient by email or phone.
