The details below are specifically tailored to regulations in Belgium. Please visit our Since January 1, 2026, the Belgian landscape for digital invoicing has irrevocably changed. Yet, several misconceptions continue to circulate, causing confusion among entrepreneurs. Are you still sending PDF invoices via email to your B2B customers? It is time for a quick reality check.
Here are the 8 most persistent e-invoicing myths, debunked for today’s reality.
1. I send a PDF, so I’m invoicing electronically
The Reality: A PDF is a digital document, but it is not an electronic invoice according to current legislation. Since January 1, 2026, a B2B invoice must consist of structured data (UBL) that can be read directly by computer systems. For the tax authorities, a PDF via email is no longer a valid invoice for VAT deduction between companies.
2. E-invoicing is only for large corporations
The Reality: This is perhaps the most dangerous myth. The mandate applies to all VAT-registered businesses in Belgium. There are no exceptions for small self-employed individuals or micro-enterprises. Everyone must be able to send and receive via the Peppol network.
3. It’s only mandatory if I work for the government
The Reality: That was the rule back in 2024. As of this year (2026), the obligation has extended to all transactions between businesses (B2B). If you invoice another Belgian entrepreneur, an e-invoice is the only legal way forward.
4. I still have time to adapt
The Reality: Time is up. The mandate officially started on January 1, 2026. Businesses that are not yet compliant risk administrative fines that can reach up to €5,000 per violation. Furthermore, your professional clients can refuse your invoice because they cannot recover the VAT based on an invalid format.
5. An e-invoice is unsafe and prone to fraud
The Reality: On the contrary. Sending invoices via email is actually the largest source of invoice fraud (such as hackers changing IBAN numbers in PDFs). Banqup utilizes the highly secure Peppol network, where the identity of both the sender and receiver is verified in advance. This makes "ghost invoices" virtually impossible.
6. E-invoicing just costs me money
The Reality: While you invest in a platform like Banqup, you save an average of €9 per invoice on printing, postage, and processing costs. Also, don't forget the fiscal incentive introduced by the federal government: you can deduct 120% of the costs for your e-invoicing software and related advice as a business expense.
7. I still need to keep my paper archives
The Reality: Absolutely not. One of the biggest advantages of Banqup is the certified digital archive. Your documents are stored securely according to legal retention periods and are immediately searchable for you and your accountant. No more shoeboxes, no more physical space wasted.
8. The transition is too technically complex
The Reality: With Banqup, the barrier is minimal. You don't need to be an IT expert to comply with the law. Our platform automatically converts your data into the required UBL format and sends it through the correct channels.
Are you meeting the 2026 standard?
The e-invoicing revolution is no longer a future prospect; it is the current standard. Businesses using Banqup benefit not only from full legal compliance but also from faster payments and a more efficient administration.
