By 2026, Belgium will take a significant step in administrative digitalization with the implementation of mandatory electronic invoicing. This legislative reform will directly impact the daily operations of Belgian companies, reshaping their processes for receiving and issuing electronic invoices. Human Resources (HR) and financial departments are on the front lines to adapt to these changes, rethink their workflows, and ensure regulatory compliance.
Towards Mandatory E-invoicing: Understanding the New Belgian Framework
With the generalization of e-invoicing scheduled for 2026, the landscape of accounting and administrative management is undergoing a transformation. The government’s goal is to harmonize the exchange of structured invoices between economic actors and to enhance VAT control. By making e-invoicing mandatory, Belgium aims to combat fraud more effectively and simplify tax management for businesses.
By this deadline, Belgian companies must be able to manage not only the issuance but also the reception of electronic invoices through secure platforms. This requires rethinking internal tools while ensuring that each transmitted document complies with the mandatory information defined by the legislative reform.
What Changes Can HR and Finance Teams Expect?
The arrival of e-invoicing will change the daily routines of HR and financial managers. One key aspect is compliance: mastering the structuring of electronic invoices and ensuring they contain all information required by regulations. This will necessitate adjustments in management software and internal procedures, particularly concerning the handling of expense reports or external services.

Reorganizing Administrative Processes
Integrating mandatory e-invoicing will require a revision of traditional workflows. Full digitization often means redefining validation steps, payment status tracking, and secure archiving. The shift to structured invoices may also reveal limitations in existing systems.
A thorough inventory of current processes will help identify key adjustments, such as in purchase request management, VAT integration on electronic invoices, or automated reconciliation with analytical accounting.
Adapting Digital Tools and Managing the Transition
Given the legislative reform, modernizing digital tools is essential. Most Belgian companies will need to invest in solutions that can issue and receive electronic invoices compliant with EN 16931 standards. Adding specialized modules, integrating signature connectors, or selecting interoperable platforms are all critical points for smooth implementation.
It may also be useful to anticipate how to evaluate the performance of teams involved in the rollout. Skills assessments and personality tests adapted to change management can help HR adjust their resources effectively during the transition to e-invoicing.
Impacts and Expected Benefits for Belgian Companies
By adopting mandatory electronic invoicing, companies can expect several benefits. These include reduced paper costs, optimized approval processes, and enhanced traceability. Faster processing times also improve payment deadline control, potentially strengthening supplier relationships.
Moreover, having structured data significantly eases audits and VAT inspections. Automation prevents many common errors or omissions related to mandatory information, reducing the risk of penalties during external audits.
List of Expected Operational Benefits
- Reduced invoice processing time through automation
- Lower costs for printing, postal dispatch, and physical archiving
- Improved accuracy and quality of transmitted data
- Increased traceability at every stage of electronic invoice handling
- Better compliance with tax rules and easier VAT audit management
These direct gains can positively impact the entire organization, especially by reducing the administrative and accounting workload.
Comparison Before and After E-invoicing Implementation
| Before E-invoicing | After Mandatory E-invoicing |
|---|---|
| Paper invoices, unstructured emails | Structured, secure electronic invoices |
| Manual data entry and repeated checks | Automation, reduced human errors |
| Long processing times, bulky physical archives | Accelerated processing, simplified digital archiving |
| High exposure to VAT errors and missing details | Easier compliance and improved audit readiness |
The table above highlights the significant evolution in practices thanks to the widespread adoption of electronic invoicing.
Preparing Teams for Sending and Receiving Electronic Invoices
Training employees on e-invoicing developments is a key lever for success. HR will need to organize awareness sessions focused on understanding mandatory fields and the technical requirements for electronic transmission.
Small hands-on workshops can simulate the processing chain, from invoice creation to approval, including automatic checks of VAT-related elements.
Key Elements to Include in Your Preparation Strategy
- Map out invoicing workflows to identify sensitive points
- Select compatible technical platforms and validate their integration with current systems
- Launch an internal communication plan about key dates and upcoming changes
- Conduct pilot tests to verify the effectiveness of new processes with targeted teams
Centralizing frequently asked questions about mandatory e-invoicing will also help reassure teams and reduce the risk of operational disruptions during the switch.
