For Alain Carels, managing director at Carbofisc, the approaching Peppol deadline of January 1, 2026, was the perfect moment to radically overhaul how the firm handles sole proprietorships. “We simply can’t keep processing invoices the way we do now,” he states resolutely. The challenge for his firm? Managing a large volume of small accounts with a limited team, without sacrificing quality or the human touch.
The Peppol deadline as a catalyst
Many firms see mandatory e-invoicing as a burden, but Carbofisc uses it as a ‘migration trigger.’ By migrating sole proprietorships to Dexxter now, the firm is 100% prepared for the digital influx. Because Peppol registration is included in the app, their clients are immediately compliant with the law, while the data flows into the firm flawlessly.
Extreme efficiency: The 80-account threshold
The figures at Carbofisc speak for themselves. Thanks to extensive automation and the move away from the complex minimum chart of accounts for sole proprietorships, output per employee has skyrocketed:
- High-Volume Management: At Carbofisc, a single account manager now effectively oversees 80 sole proprietorships. This is possible because the “input burden” lies entirely with the client.
- No more hieroglyphics: The biggest frustration in the workplace — illegible handwritten daily receipt books — is a thing of the past. Entrepreneurs now record their receipts digitally via the app. The result? Accounts that arrive 100% legible and accurate.
- Super-smart AI safeguards: Alain’s employees rely on Dexxter’s built-in logic. Errors involving VAT reverse charge or investments are proactively blocked. “It’s almost impossible to overlook any steps now,” they say.

Peace of mind in the workplace
By eliminating administrative burdens, Carbofisc has regained the focus on what truly matters. The accountant acts as a quality controller who looks over your shoulder, rather than a typist chasing down receipts. For Alain, the switch to Dexxter is therefore an investment in his team: “It gives us the peace of mind to do what we really love: advising our clients and providing fiscal guidance.”
