Electronic invoicing: general information

An electronic invoice is a process of sending and receiving invoices from one software program to another, eliminating the need to send PDF invoices between companies.

What is an electronic invoice?

An electronic invoice is an invoice issued, transmitted and received in a dematerialised form and containing data in a structured format, which allows it to be processed electronically.

To issue and receive electronic invoices, the company must choose an approved platform.

In a single operation, you will be able to:

• send the invoice to your customer;
• automatically feed your accounts, depending on the accounting software;
• directly transmit the necessary data to the tax authorities.

WAY-Plan complies with electronic invoicing regulations, as it is backed by an approved platform for sending sales invoices.

Who is affected?

The process is becoming widespread in Europe and is becoming mandatory:

• In Belgium from 1 January 2026. All invoices between businesses (B2B) subject to VAT must be sent via the Peppol network.
• In France from 1 September 2026. Electronic invoicing applies to all invoices issued between French entities subject to VAT, which must be sent in electronic format via an approved platform (PA or PDP).

What information is sent

As it is no longer necessary to send the PDF invoice, the raw data is transmitted to your customer's platform for analysis and processing.

The following data is transmitted for each invoice:

General invoice information:

• Invoice number
• Invoice issue date
• Buyer information: name, full address and electronic billing address (ID)
• File reference, if provided
• Seller information: name, full address and electronic billing address (ID)
• Payment details: IBAN associated with the business entity or customer, if different
• Expected payment date: payment date, if specified in payment management, or within 30 days by default.
• Tax details by VAT category (standard rate, reduced rate, exempt, zero, etc.)
• Invoice amount details: Total excluding VAT, Total VAT and Total including VAT payable

Information sent for each fare line:

• Assignment number and description of the type of service and service
• Description (only for assignment category expenses): Assignment reference, if provided,
• Assignment details in the contact's language. 
  Example of details: 8 January 2026: CDG AIRPORT (16:30:00) -> Gare Saint-Lazare, 13 Rue d'Amsterdam, 75008 Paris, France (19:00:00) 4 Passengers: Mr Steevy Bret, Mrs Simon
• Quantity
• Unit price excluding VAT
• Tax details: VAT rate + VAT category
• Discount amount, if specified + discount code (default: commercial reason)
• Total excluding VAT

Please note:

• If additional charges are invoiced, there will be as many lines sent as there are additional charges invoiced. These will contain the same information as in the example above, without the mission description.
• The amount including VAT for each assignment line is not sent! There may be rounding issues that are not caused by WAY-Plan but by the way electronic invoicing between companies works, based on the amount excluding VAT for the services.
