From January 1, 2026 onwards, electronic invoices (e-invoicing) have become mandatory for all B2B transactions between Belgian businesses. Fortunately for those who've missed the deadline, there was an extended grace period during which the government would refrain from imposing fines. That grace period is now over.
As of April 1, 2026, mandatory e-invoicing via Peppol — the dominant network — officially comes into force for VAT-liable Belgian businesses. Companies not yet connected to the Peppol network are at risk of being fined.
⚠️ Quick recap: what's at stake? VAT-liable businesses that still aren't sending e-invoices via Peppol or an approved platform today risk fines. Organizations including KVABB and NSZ have asked for an extended delay, but this wasn't granted. |

The fines are rather severe and moreover, they're progressive for those who refuse to be connected with the Peppol-network:
Offence | Fine |
|---|---|
First offence | €1,500 |
Second offence | €3,000 |
Third offence or later | €5,000 |
It should be noted that those companies are also missing out on the advantages of e-invoicing. Because anyone who sees e-invoicing as just a compliance box is missing half the picture. Let's look beyond the fine for a moment.
What you're missing if you haven't switched yet
E-invoicing isn't just a compliance checkbox. It's also how your invoice processing finally stops wasting time. Here's what you'd be leaving on the table today by not being connected to the Peppol-network:
Money flows fasterElectronic invoices arrive instantly, no lost envelopes, no "I never received it". While the first data is not conclusive yet, e-invoices are expected to get paid faster. Moreover, clients have the legal right to start refusing your non-compliant invoices. | Automatic processingNo more manual data entry. Peppol invoices are read directly by your accounting software. That saves hours per week at higher volumes. |
Fewer errors, less reworkStructured data means fewer typos, fewer credit notes, less back-and-forth email. Your accountant calls you less, and that's a good thing. | 120% tax deductibleUntil end of 2027, investments in e-invoicing software are 120% tax deductible. Your net cost drops below what you actually pay, the government chips in. |
Also: one tool is not the same as another. Think wisely. Not every tool enables you to reap the above benefits of e-invoicing as much as another.
✅ To put it in perspective Businesses that handle e-invoicing via Cashfeed save an average of 5 to 10 minutes per incoming invoice, mostly on digitizing, approving, paying and booking the invoice. At 100 invoices a month, that's easily a full work day, every single month. |
