Normally it takes about one week for the setup to be executed. After that the invoices will be sent according to your requests. Please notice that no beforehand confirmation will be sent.
Also, please note that we can only send the references which are specified in the shipment information. We have no possibility to add references or verify if these have any specific format etc. That correct references are used must be secured by the one providing shipment information. For this reason we don’t accept rejection of invoices due to missing or incorrect references.
