Peppol BIS (Business Interoperability Specification) are a set of technical specifications designed to enable seamless and interoperable document exchange within the Peppol network.

UBL stands for Universal Business Language, a standard language for exchanging electronic documents, such as invoices. It is a file in XML format and has .xml as its file extension.

Through the Peppol network you can, in addition to invoices, also exchange response messages with your customers or your suppliers. There are two types of response messages, namely IMR and MLR.

Hermes is a web application developed on behalf of BOSA. Thanks to Hermes, suppliers can send structured electronic invoices to all their Belgian clients, even those who cannot yet process these electronic invoices automatically.

To send an invoice through Peppol, create an account with a Peppol Access Point provider. You know your customer's Peppol identification (PEPPOL ID). You provide your provider with the structured electronic invoice. Your provider delivers your e-invoice to your customer's Peppol Access Point. Your client receives your invoice.

As the name suggests, a Peppol Access Point is your gateway to the Peppol network. It's a service you purchase from a service provider, such as IxorDocs (a certified Peppol Access Point). By using a certified Peppol Access Point, you can easily and securely send and receive e-invoices to and from any organization connected to the Peppol network, regardless of country or industry.
