What is e-Invoicing?

e-Invoicing is the process of sending invoices electronically, also known as electronic invoicing. In some countries, electronic invoicing is mandatory. Especially in the B2G sector, e-invoicing is required according to EN 16931.

The invoice data is directly converted into a specific format. The format used often depends on the country and is usually XML-based. The invoice data is then sent to the invoice recipient's system via a network.

In Europe, Peppol is widely used. Peppol supports the 2014/55/EU regulation. In Germany, the ZUGfERD or XRechnung format is often used. billwerk supports all common formats.

The benefits of e-Invoicing is the reduced effort and costs in providing the invoices and the lower risk of errors. In addition, the formats of the electronic invoices can be processed automatically.
