Your Belgian Customers Can Send E-Invoices, But Can You Receive Them?

Why your business might be missing incoming e-invoices without knowing it

Many SMEs focus on sending e-invoices to comply with regulations but overlook the equally important requirement to receive them. If your business isn’t registered to receive structured e-invoices, you may not even realize invoices are being sent to you in a format you can’t process.

As of January 2026, PDF invoices are no longer compliant for VAT-liable businesses in Belgium. Yet, accounting firms report that a significant share of SMEs still rely on manual processing for incoming invoices. This creates a hidden risk: unregistered businesses may face fines, disrupted cash flow, or missed payments due to delayed or lost invoices.

Who needs to comply and what happens if you don’t

All VAT-liable enterprises in Belgium must be able to receive structured e-invoices, even if their primary customers are consumers. This requirement applies broadly, including micro-enterprises, self-employed professionals, and businesses in construction, rental, and liberal professions.

Non-established VAT-registered businesses are exempt from sending e-invoices but must still comply with receiving requirements. Failing to do so can result in operational disruptions, audits, or penalties, even if the oversight is unintentional.

The hidden costs of ignoring e-invoice receiving requirements

Manual processing of PDF invoices increases administrative workload and introduces errors. Teams spend time converting, validating, and entering data instead of focusing on core tasks. Over time, this inefficiency adds up, creating unnecessary costs.

Delayed or lost invoices can strain supplier relationships and disrupt cash flow. Non-compliance may also trigger audits or penalties, adding unexpected financial burdens. Businesses without a receiving solution may struggle to scale or onboard new suppliers, limiting growth opportunities.

How to check if your business is ready to receive e-invoices

Start by verifying whether your accounting or invoicing software supports structured e-invoice receiving. If it doesn’t, you’ll need to explore alternatives.

Next, check if your business is registered in the Belgian Peppol directory or an equivalent network. Without registration, suppliers may send invoices in a format your system can’t accept. Test receiving a sample e-invoice from a supplier or partner to confirm functionality. If you’re unsure, consult your accounting firm or software provider to identify gaps in compliance.

Steps to set up e-invoice receiving quickly and cost-effectively

Choose a certified e-invoicing platform that integrates seamlessly with your existing accounting software. This ensures minimal disruption to your workflows while meeting compliance requirements.

Register your business in the Peppol network to enable seamless receiving. Once registered, train your team on processing incoming e-invoices to reduce manual work. Automate invoice validation and approval workflows to improve efficiency and reduce errors.

What to do if you’ve already missed invoices or compliance deadlines

If you suspect you’ve missed e-invoices, audit your recent transactions to identify any that were sent electronically but not received. Contact suppliers to request re-sending missed invoices in a compliant format.

Work with a certified provider to implement a receiving solution as soon as possible. Document your compliance efforts to demonstrate good faith and mitigate potential fines or penalties. Taking action now can prevent further disruptions and ensure your business stays on track.
