Early October 2025, figures showed that 66% of Belgian companies are still unprepared for e-invoicing, which becomes mandatory on January 1, 2026.
This deadline falls right in the middle of the end-of-year holiday season in Belgium. And while Christmas celebrations can afford a bit of improvisation, the implementation of electronic invoicing requires structured preparation that cannot be left to the last minute.
It’s often said that Christmas preparations seem to start earlier every year. That may be true, as everyone promises to plan ahead to avoid the holiday rush. Yet, last-minute shopping and preparations always end up happening. For shops (including online ones), caterers, and other providers of goods and services, this leads to unmanageable peaks.
The problem for you? Your users are likely to take the same last-minute approach to implementing electronic invoicing.
Can your team cope with last-minute rush?
Just like every supplier of Christmas goods and services wants to avoid the holiday rush and prevent bottlenecks, your software company has a strong reason to act early. The sooner you get users on board, the better.
Because if they all realize at the last minute that they need an e-invoicing system, your team could be flooded with support requests you simply can’t handle. And that’s not a win-win situation for you and for your users.
Of the 1.2 million businesses currently registered in Belgium, almost 800,000 are still not set up for Peppol e-invoicing. How much business could your company gain in from this adoption gap?
Educating your users
Are some of your users are not aware of their obligation to have an e-invoicing system in place?
- Check in with them, explaining the situation and how you can help: Are your users aware of the e-invoicing mandate, but have taken their eye off the ball (maybe because they’re thinking about Christmas) and lost track of how urgently they need to act?
- Remind them of the deadline and how long it will take to get them ready: Do your users realise that the shift to e-invoicing via Peppol means completely rethinking their workflows? Do they know that e-invoices will land directly in their bookkeeping system, meaning manual approval flows involving printing, stamping and booking invoices by hand become irrelevant?
- Ensure they are aware of this fundamental shift and have planned new workflows.
