Why is there an “Invoice by post” function and who can use it?
Invoice by post can be requested exclusively by tradespeople in Germany and businesses in the EU that possess VAT identification, since they require an invoice on paper or with an electronic signature under certain circumstances. Signing for many customers would currently represent a disproportionate amount of extra effort, which we cannot enter into in the interests of our customers. For this reason we offer you the possibility of requesting invoices by post. However, most tax offices currently still accept printed-out PDF invoices.
We would therefore ask that you only request invoices by post if you really need them on paper (e.g. for your tax advisor or in the case of a possible tax audit). It is not necessary to request each invoice separately, but rather to collect them over longer periods of time! The invoice is still considered as having been delivered on the date of the invoice (identical to the date the e-mail was sent), i.e. the due date of the invoice is not affected by the receipt of the invoice by post. A PDF invoice without signature is sufficient for customers not belonging to the above-mentioned group of customers.
