By 2026, electronic invoicing via Peppol will become mandatory in Belgium. Many companies already have an ERP or custom IT system that works perfectly for their business… but is not Peppol-compatible.
Changing software represents a high cost (often tens of thousands of euros) and considerable time loss. To meet this need, Flexina has launched Peppol Box Integrations, a simple and fast service that makes your existing systems Peppol-compatible.
Electronic Invoicing 2026: Connect Your ERP or In-House System to Peppol
Avoid Costly Migration
With Peppol Box Integrations, you don't need to replace your ERP or in-house solution. We adapt your current system to UBL/Peppol format without disrupting your organization.
Meet Legal Obligations
From 2026, all B2B invoices in Belgium must go through Peppol. With our service, you ensure compliance without waiting until the last minute.
Continue Using Your Current Tools
Your teams don't change their habits: you keep your internal processes while automatically producing compliant electronic invoices.
How Does Peppol Box Integrations Work?
Our service adapts to each company's reality. Depending on your needs and how your invoices are generated, several technical solutions are possible:
1. API Connection – Direct Integration
If your ERP or custom system can communicate in XML UBL or via an API, we set up a gateway that sends your invoices directly to the Peppol network.
2. PDF Conversion by Artificial Intelligence
Your invoices only come out as PDFs? Simply send them by email to a dedicated address. Our AI servers automatically convert them to Peppol-compliant UBL electronic invoices.
3. Adaptation of Your Existing Formats
Whether it's CSV, Excel, JSON or even proprietary formats, our converter handles most cases. We analyze your exports and create a custom transformation to UBL/Peppol.
Personalized, Secure and GDPR-Compliant AI
Our artificial intelligence technology is not a generic tool: it is personalized for each client to understand your invoice structure, layouts and business specifics.
It is hosted exclusively on our European servers and strictly complies with GDPR. No data passes through American or Chinese services: the confidentiality of your information is guaranteed.
We train and adjust our AI on your own documents and use cases. This personalization achieves near 100% accuracy: your invoices require no re-encoding, a simple verification is enough before they are automatically transmitted to Peppol in structured UBL format.
Advantages of Peppol Box Integrations
- Rapid compliance: operational within days after ordering.
- No ERP change: you continue using your current system.
- Significant savings: no need to invest in new management software.
- Privacy and GDPR compliance: your data stays in Europe, under control.

An Exclusive Service with Limited Capacity
Our service is deliberately highly personalized. Each integration requires advanced technical support, which naturally limits the number of clients we can handle in parallel.
First come, first served. With the 2026 deadline approaching, it's essential to book your slot now. Waiting means we may not be able to help you in time for compliance.
In Summary
With Peppol Box Integrations, you continue using your ERP or custom IT system while complying with Belgian 2026 legislation.
You change nothing in your internal organization: your invoices simply become structured UBL files sent via Peppol, reliably, securely, GDPR-compliant… and on time.
