E-Invoice is coming to Germany! b.invoice helps! Electronic invoicing will become mandatory for all B2G companies from 27. November 2020

With the legal guidelines 2014/55/EU the government created the basis for standardized digital invoice format with mandatory implementation as from 27. November 2020.

For your company this means that sending of invoices to federal institutions can only be done via X-Rechnung by a PEPPOL Access Point from 27. November 2020. Local federal institutions have already used X-Rechnung since 18. April 2020. Processing of paper-based invoices is no longer supported and also no longer possible.

Our product b.invoice will help you to create and send invoices in the necessary X-Rechnung format.

BESITEC is a certified PEPPOL access point provider…
…now for AS4, too.

We are proud that our b.invoice product could reach the certification for AS4 in addition to the existing AS2. Consequently we are a member of the official list of all PEPPOL Access Points that support AS2 and AS4.

We can promise that our customers will continue to have access to our PEPPOL access point in the future. We keep b.invoice up-to-date so our customers can continue sending e-invoices without any worries.
