Question and answer

Compared to the exchange of paper or digital (PDF) invoices, a lot of money can be saved by using an eInvoice. For the sender of the invoice in particular, costs of printing and delivery are reduced. Furthermore, being able to offer an eInvoice is starting to become business as usual. Customers expect to be able to receive an eInvoice from their service providers. The (Dutch) federal government already has a paragraph published in her new tenders asking for an eInvoice.

The Energy eInvoice makes use of the basic invoice SI-UBL, that is compliant with the NL-CIUS guidelines. When you implement it, you are easily able to access the PEPPOL infrastructure, a network of billing service providers (BSPs), and to send and receive invoices in multiple business areas. More and more accounting systems are able to support this format. This way both large and small commercial customers are able to profit from an electronic invoice.

Compared to the exchange of paper invoices, a lot of money can be saved with the eInvoice. The money-saving for the receiver of the invoice relates mainly to the handling or the information on the invoice. After completion of the integrity check, an eInvoice can be imported right away in your administration. Manual input is not necessary anymore and this will save you a lot of time and mistakes.

A growing network of suppliers, receivers and service providers has been connected by the PEPPOL-network. Since the Energie eInvoice uses the SI-UBL core e-invoice, you are in fact choosing a future proof NL-CIUS implementation. Furthermore, the Energy eInvoice offers you an extension with supplemental sector information (among others meter readings) which enable further automatic handling and approval of your energy invoices. You can contact your supplier and/or measuring company for this.

The standard Energy eInvoice is limited to agreements about the meaning and completion of the invoice elements and the format used to send them. For that we refer to the invoice format of Simplerinvoicing (SI-UBL). To be able to send/receive the message technically, you will have to make further agreements with your clients/supplier about the means of communication that you’re going to use. For instance, you can send the invoice as attachment in an email, realize a web service connection or make use of services/platforms of third parties (billing service providers). The various options all have their pros and cons. Please seak the advice of an expert.

The participants of Simplerinvoicing (billing service providers and ERP/accounting software suppliers) offer the facility of sending and receiving invoices via a safe channel (SI FULL). For more information, see: www.simplerinvoicing.org

You can find the most recent version of the Standard Energy eInvoice on the Changelog page.

At this moment, a new version of the extension or xml-standard is not planned.

Some improvements for the documentation and current release are on the backlog:

  • clarification of the use of dates (up to vs. up to and including w.r.t. usage period)
  • addition of more example e-invoices in xml

Yes! For basic invoice information we refer to the SI-UBL specification, which is a UBL implementation. The UBL standard for invoices describes XML elements which together form a UBL invoice. UBL intends to be universal and is being used quite a lot, but because of this universal character the number of possible XML elements in an invoice is very large (>2.000 elements). A big part of these is not relevant to the basic invoice and SI-UBL therefore is a subset of about 150 elements. The Energy eInvoice adds a specific sector extension to be able to exchange sector specific information (such as meter readings) in a structured format.

A test tool is availble, at the website of the Dutch Peppol Authority (Nederlandse Peppolautoriteit – NPa). Use the option “Valideer as a different format” and select Energie eFactuur 3.0.0.

Since April 2019 the Standard Energy eInvoice is maintained by NEDU (Dutch Association for Energy Data Exchange). Within NEDU a task force handles issues, changes, requests to further develop the Standard Energy eInvoice if necessary.

At most once per year a new version of the Standard is released. If your organisation is interested in joining this task force, please contact us at info @ energie-efactuur.nl.

The Energy eInvoice is an open standard. This means the standard can be used freely and everybody can contribute to further development.

Being supplier, network administrator or measuring company means you can participate in the task force and contribute to further developing of the standard. Customers/receivers of the Energy eInvoice are also invited to make their vision and demands known in or to the task force.

Participation offers a quicker insight in the latest developments and being able to influence the content of the standard. Are you interested or looking for more information? Please contact us at info @ energie-efactuur.nl

Please send your proposed change to info @ energie-efactuur.nl. The request will be handled and considered in the working group.

Not more than once a year a new version of the standard will be published in which possible changes will be applied. Additions to the code lists may be applied interim.

For substantive questions about the standard you may contact our helpdesk via helpdesk @ energie-efactuur.nl.
