Invoicing

Invoicing & frameworks

If you have an invoice for one of the Enexis Groep companies, please make sure that the invoice has the correct name details and is sent to the relevant company.

Our standards frameworks contain all the information that an invoice must fulfil. These are statutory obligations, tax obligations and data that are important for the accounting of the Enexis Groep.

From 1 November 2020, Enexis Groep will no longer accept invoices without a formal purchase order. It is therefore mandatory to state a valid PO number on the invoice. Your client will provide you with the PO number by means of a formal purchase order.

E-invoicing

From April 2019, Enexis Groep will switch to e-invoicing. This allows invoices to be processed completely digitally. This is easier and takes less time. Together with our suppliers, we will ensure that the switch goes as smoothly as possible.

What channels does Enexis Groep use?
Enexis Groep uses three options to connect our suppliers to e-invoicing:

  • Simplerinvoicing
  • Secured connection based on the European Peppol standard
  • Web service endpoint
  • Connection with our partner Esize
  • E-mail
  • Connection via the sending of XML invoices by e-mail

How does it work?

Almost all accounting systems are suitable for e-invoicing using XML files. As a supplier of Enexis Groep (or one of its affiliated companies), we ask you to register your company using the form below.

Upon receipt of the form, we will contact you to initiate the connection process. There are no charges for this process.

Frequently asked questions

What is electronic invoicing?
With e-invoicing, an invoice can be processed fully automatically in the accounts without the need for manual intervention. In short: machine-2-machine. This is possible because the digital message complies with an agreed structure and therefore no differences in interpretation can occur.
How can I send e-invoices via e-mail?
If you have a software package that allows e-invoicing, you can add an XML file to the e-mail by means of a setting. This must comply with the UBL 2.1 standard in order to be processed correctly. After a test invoice and coordination with Enexis, you can invoice in this way from then on.
What exactly is an e-invoice?
A real electronic invoice is created in UBL and consists of predefined fields. Financial software can automatically read the e-invoice and enter it seamlessly into the accounts. This is in contrast to invoices in other formats such as PDF, Word or Excel.
What is UBL?
UBL is the abbreviation for Universal Business Language. It displays the contents of an electronic invoice in file form. It is in fact nothing more than a series of agreements on a digital data structure in a certain standard format. A UBL invoice can be read by any accounting program that adheres to this standard format and thus be entered automatically. Enexis uses the UBL 2.1 standard for its incoming invoices.
What are the benefits of e-invoicing?
  • Easier: processing is automatic
  • Faster: no more paper flow
  • More accurate: no errors due to manual processing
  • More sustainable: less paper consumption and lower CO₂ emissions
What options are there to send an e-invoice to Enexis?
  • Submit e-invoices from your accounting or other software package via Simplerinvoicing.
  • Direct link via a web service.
  • Send e-invoices in UBL 2.1 format via e-mail.
