All the FORNAV Solutions


Why is e-invoicing important?

E-invoicing is rapidly replacing paper invoices reducing manual work, minimizing errors, and accelerating payment processing. It’s gradually becoming mandatory in many European and other countries to improve tax transparency and efficiency.

For businesses, compliance with these regulations is essential to avoid penalties, streamline financial workflows, and keep being competitive in global markets. As a natural consequence, businesses using Microsoft Dynamics 365 Business Central (BC) need an easy, secure, and affordable way to create and exchange e-documents.

Why do I need FORNAV E-invoicing in addition of the Business Central e-invoicing functionality?

FORNAV extends the standard BC functionality with functionality to support the creation and automated exchange of e-documents using the Peppol network.

Out of the box, BC lets you manually exchange (i.e. sending or receiving as email + attachment) XRechnung UBL e-documents. BC does not offer any automated transport of e-documents. Practically, this means that you will have to use the “send email” functionality in BC to send out your e-invoices as attachments. And, you will have to manually import the invoices that you receive by email into BC.

If you want to automatically exchange e-document, Microsoft recommends ISV solutions such as FORNAV E-invoicing.

When using FORNAV E-Invoicing, you can do all standard BC can do (creation and manual exchange of XRechnung UBL e-documents) – but you also get:

  • The possibility to create and transport CII e-documents (ZUGFeRD and XRechnung)
  • The automated transport of e-documents through a seamless integration with Peppol including automatic look-up of companies in the Peppol Directory as well as preview and validation of e-documents before sending

What e-documents formats are supported in standard BC?

Standard Business Central supports UBL (for example XRechnung UBL). However, if you are using or planning to use CII-based documents such as ZUGFeRD and the CII XRechnung, you will have to complement BC with another solution.

Is this potentially an issue? Not necessarily, but it can be. Many companies have already started using CII-based e-documents, for example ZUGFeRD or XRechnung. If this is your case, you need more than the standard BC functionality. Also, if any of your business partners (customers, suppliers) use CII-based e-documents, you will need a system that supports the CII format – and therefore you will need more than the standard BC functionality.

What is ZUGFeRD?

ZUGFeRD, short for “Zentraler User Guide des Forums elektronische Rechnung Deutschland” (Central User Guide of the Forum for Electronic Invoices Germany), is an open standard for electronic invoices. Developed in Germany, ZUGFeRD is designed to facilitate the exchange of structured electronic invoices in a format that combines both human-readable and machine-readable data.

The core idea behind ZUGFeRD invoices is to create universally compatible invoices that can be read and understood by humans while also being processed efficiently by computer systems. It achieves this through the use of PDF/A-3, a standard PDF format, combined with an embedded XML file. This unique combination ensures that the invoice is accessible to all, regardless of the recipient’s technological capabilities, while also enabling automated data extraction and processing.

While XRechnung is compulsory for public procurement, ZUGFeRD is an alternative option for broader invoicing needs. It is widely used in both the public and private sectors due to its flexibility.
The current XRechnung and ZUGFeRD standards only allow two XML formats for the transmission of electronic invoices: either UBL or UNCEFACT/CII. The ForNAV e-invoicing solution supports the UNCEFACT/CII standard.

What is XRechnung?

XRechnung is an XML-based invoice format that has been chosen as the standard for electronic invoicing for public sector clients in Germany, to comply with EU directive 2014/55/EU. EU directive 2014/55/EU requires the use of electronic invoicing in public procurement across the EU to improve efficiency and reduce costs.

The XRechnung standard defines how invoice information should be formatted and transmitted using XML. It ensures that various software systems can receive and process electronic invoices seamlessly.

What is Factur-X?

In addition to ZUGFeRD and XRechnung, another notable electronic invoices standard has gained prominence: Factur-X.

Factur-X (FacturX) is a format used primarily in France and that is designed to be compatible with both French and German invoicing requirements. While it originated in France, it has gained recognition in other European countries as well, making it suitable for international invoicing. It combines the advantages of both PDF and XML formats, making invoices human-readable while maintaining machine-readability.

What is Peppol?

One of the easiest and most secure ways of distributing e-invoices while meeting regulatory requirements is using the fully automated transmission via the Peppol network (Pan-European Public Procurement On Line). Peppol is a compilation of components and specifications enabling the standardized exchange of documents between different business partners, using the infrastructure of the Peppol network.

Sending e-invoices using the Peppol network is one of the transmission methods accepted by all authorities, and the only one supporting machine-to-machine communication and the mass sending of e-invoices.

Out of the box, Microsoft supports the creation and manual exchange (sending or receiving as an attachment to an email) of XRechnung UBL e-documents. The transport of e-documents is not included. To automatically exchange e-documents from Business Central, you need an additional solution – FORNAV Peppol Plus is that solution.
