Data Merge Finance for Belgian trustees faced with mandatory electronic invoicing

Since 1 January 2026, the structured electronic invoice has become a major operational issue for Belgian trustees.

The trustee must absorb more than invoices

The subject is not just receiving more electronic documents. It is also necessary to integrate these flows into accounting, maintain control over controls and avoid recreating manual tasks at each stage.

1. Let the client work in his tool

Customers want to keep their LES or management software. With Data Merge Finance, the trustee can preserve this use without breaking the accounting flow.

2. Automatically synchronize financial flows

• Sales invoices transmitted without rescission
• Purchase invoices integrated into the accounting flow
• Cleaner data for both the firm and the customer

3. Maintain control through draft mode

Automation does not remove accounting control. The entries may be sent in draft for validation of imputations, VAT rules and any adjustments.

4. Reduce double entry and errors

Less collection means less errors in amount, date or reference, and better consistency between the client's tool and accounting.

5. Transforming the obligation into a competitive advantage

• Better support clients
• Gaining efficiency internally
• Sustainable improvement of quality of service

In Belgium, firms already have an interest in industrializing flows that are actually rotating. In France, this logic gives a lead time to structure future flows before they get in charge.

Conclusion

Data Merge Finance helps trustees reconcile customer autonomy, compliance, performance and accounting quality. This is a very concrete response to absorb already active Belgian flows and to prepare future extensions more calmly.
