Navigating the 2026 Mandate: B2B Compliance FAQ Belgium
This B2B compliance FAQ Belgium is updated for May 2026 to reflect the end of the administrative tolerance period. Whether you are a solo entrepreneur or a growing SRL, these answers provide the technical and legal clarity needed to avoid the 1.500 € fines now being enforced by the SPF Finances.
The e-invoicing law officially started on January 1st, 2026, but the Belgian tax authority (SPF Finances) provided a three-month tolerance period for administrative errors. As of April 1, 2026, this grace period ended. Fines of 1.500 € per audit failure are now active, and “learning errors” are no longer accepted as an excuse.
No. The law applies to all B2B transactions between companies established in Belgium. This includes freelancers (indépendants), management companies (SRL/BV), and non-profits (ASBL/VZW) that engage in commercial activities. If you have a VAT number and bill other businesses, you are in scope for the rules outlined in this B2B compliance FAQ Belgium.
No. A PDF, even if it contains data, is not a “Structured Electronic Invoice” under the new mandate. To be compliant, the invoice must be a UBL (Universal Business Language) file transmitted via the Peppol network. Emailing a PDF is now considered a “paper equivalent” and is legally invalid for B2B transactions.
The Belgian government encourages digital transition by allowing SMEs to deduct 120% of the costs related to e-invoicing implementation. This includes our setup fees and your software subscriptions (like OkiOki). Essentially, the government subsidizes a significant portion of your compliance via your corporate tax return.
Our setup includes a fallback “Bridge” solution. If your client is not yet on the Peppol network, the system delivers the invoice via a secure portal or email while simultaneously generating the mandatory UBL record for your own tax compliance. As we often advise in this B2B compliance FAQ Belgium, this ensures you stay legal even if your customers are lagging behind.
Yes. OkiOki uses PSD2-compliant encryption, which is the highest European standard for financial data sharing. At Bewebwise, we operate a strict “Zero-Storage” policy: we never see, store, or log your bank passwords. You remain the sole master of your banking credentials.
Not necessarily. Our Readiness Support sessions are designed to bridge the gap between your current workflow (Word, Excel, or legacy tools) and the Peppol network. As noted throughout this B2B compliance FAQ Belgium, we provide the technical “UBL engine” so you don’t have to invest in a massive, expensive ERP migration.
NIS2 is the new European cybersecurity law. While it primarily targets “Essential” entities, those large companies are now legally required to audit the security of their SME suppliers. If you lack basic NIS2 readiness or registration on the Safeonweb@Work, you risk losing contracts with larger corporate clients.
As of January 2026, new federal laws require a formal “Absence Management” policy. Without this update, you face Level 2 social fines, and your internal rules could be declared void in a labor court dispute. We provide the mandatory templates during our HR readiness sessions for you to finalize with your social secretariat.
Since the tolerance period is over, the most important step is to demonstrate proactive remediation. By booking a Compliance Setup session, you create an official paper trail showing you are actively moving toward compliance. This documentation can often be used as a defense to significantly reduce or waive initial administrative fines.
Yes. Our Emergency Fast-Track Setup is designed specifically for Belgian companies experiencing technical blocks. We step in to fix the API bridge and ensure your invoices are successfully transmitted to the Peppol network without further delays.
We update this B2B compliance FAQ Belgium monthly to stay aligned with the latest circulars from the Centre for Cybersecurity Belgium (CCB) and SPF Finances. As the 2026-2027 roadmap progresses, we include new technical standards for UBL mapping and cross-border Peppol transactions to ensure our clients never face technical debt.
Absolutely. We encourage management teams to use this B2B compliance FAQ Belgium as a foundational guide for their internal digital transition. Understanding the “why” behind the shift from PDFs to structured data is essential for administrative staff. For a more hands-on approach, we offer specialized Support Blocks to walk your team through the actual software interfaces.
