Making use of the European Norm for all your document exchanges? Smart!

You probably first heard of the European e-Invoicing standard EN-16931 when a government client invited you to send your invoices electronically. Depending on the region you’re active in, you were asked to adopt Mercurius or SimplerInvoicing or XRechnung or even another brand. Right?

EN-16391 is widely supported by many FinTech applications, in Europe and beyond. It might be a smart move to make use of this standard as a cornerstone for your end-to-end digital strategy to achieve touchless processing and payment acceleration. Good to know: there’s no need to contact local service providers when you’re planning an international e-Invoicing roll-out.

This post is about the importance to partner with an experienced provider that has the knowhow and resources to take care of your cross-border invoicing flows. For both B2G ánd B2B.

One standard fits all?

Mercurius, XRechnung, UBL.BE, NHS England, Factur-X, ZugFerd, SimplerInvoicing, Chorus Pro, E-Rechnung, … Are they one and the same standard?

Not really. Those names correspond to regional implementations. Local legislation or industry specific requirements sometimes call for stricter instructions (CIUS) or extensions (EXT) to the EN-16931 core definition. That doesn’t have to be a show stopper, though, when your service provider actively supports the regional and sector specific deviations.

And yet …All national brands refer to the same, common standard for e-Invoicing: the European Norm EN-16931. And most of them are connected to the Peppol e-Delivery network. Don’t be put off by their different naming and know that AdValvas Europe has expertise to advise adeqautely.


EN-16931 as your digital first strategy? It’s up to you.

Your business situation gets more complicated when you operate in different regions or if the industry you’re active in has specific requirements. Most business applications have been adapted to the European e-Invoicing standard, and it’s use in B2B exchanges has become more and more prominent. Also, many European suppliers are connected to the Peppol network, there was not really a choice. Why not take this opportunity to get your entire business ready for digitalized procurement, guaranteed delivery, touchless processing, and payment acceleration?

As soon as you endorse this internationally accepted way of working, you get access to a promising, expansive market:

  • B2G as well as B2B exchanges.
  • Cross-border transactions as well as national presence.
  • Inbound (purchase invoices) as well as outbound (sales invoices), and even other procurement documents.


Don’t be hindered by late adopters

Not all your business partners have a digital presence. Especially SMEs do not. They still use mainly email for their document exchanges. But don’t let that become your problem. Your digital strategy shouldn’t be slowed down by business partners who are hesitating to jump on the digital train.

Some implementations even focus on that ‘dual speed approach’, such as Factur-X in France and ZugFerd in Germany. Those standards upgrade a human-readable PDF to a machine-readable document by enclosing the digital version in UBL or CII syntax. We call this a hybrid PDF.

So, when you’re asked to send PDF documents via email, why not provide a secured hybrid PDF? Your business partner does not have to change his process, but his accountant, when ready, gets the benefit of automated processing.

What to expect from an e-Invoicing service provider

Make sure to select a service provider (a certified Peppol Access Point) that has proven experience with international, industry specific support. While he takes care of all the technical aspects of your e-Invoicing flows, you can fully focus on your core business.

This is what you should expect from an experienced service provider:  

  • To protect you, and isolate your back office, from technical complexity.
  • Toknow how to manage regional and industry specific deviations to the EN (CIUS and EXT).
  • To translate your documents into the preferred syntax for your partners.
  • To actively promote the European Norm, with minimal friction.
