E-invoicing support - De btw-lijn

In short,
it’s time to act

Many EU-countries are introducing mandatory (structured) e-invoicing and e-reporting in the coming years.

As from 1 January 2026 Belgium obliges:

All Belgian based VAT taxpayers to issue structured electronic invoices for B2B supplies in Belgium.
All non Belgian VAT taxpayers with a Belgian VAT number to be able to receive structured electronic invoices for local B2B supplies in Belgium.

1. Independent e-invoicing software comparison

For who: taxpayers seeking independent advice on the best e-invoicing solution. This can be the activation of a solution in your current ERP or accounting software, or an integration with an e-software solution from an external provider.

Why: The right e-invoicing software differs per organization. Therefore, we do not partner with a specific e-software solution provider but rather collaborate with almost all providers. This allows us to compare different solutions on different parameters (e.g. compatibility with current systems, implementation timeline, user friendliness, compliant with rules in other countries if applicable, set-up and recurring costs,…).

What: Our independent e-invoicing software comparison includes the following:

Basic training on e-invoicing (1.5u). During this training we explain the basic principles, terms and buzzwords in e-invoicing. This will ensure better conversations with software providers, easier reporting within your organisation and (during implementation) a smoother cooperation with the IT department.
Analysis of your current activities (to identify which countries can impose requirements on e-invoicing) and of your invoicing and accounting processes including the exceptional invoicing flows.
Shortlist of 3 software solutions (current ERP or accounting system and/or third-party software providers).
Organization of and guidance during meetings with the 3 short listed supplies (3 meetings of approximately 1-2 hours).
Delivery of a software solution scorecard with a recommended “best choice”. We score on a diverse number of parameters such as implementation costs, country coverage, recurring cost, scaling for potential growth, financial stability of the provider, compatibility with current ERP and accounting system,…).
