The biggest hurdle for an accounting firm to let the client do their own bookkeeping is often fear. Fear that the entrepreneur will choose incorrect VAT percentages, record investments as ordinary expenses, or simply miss deadlines. But what if the software makes those mistakes physically impossible?
Fiscal guardrails at the source
In Maarten’s demo, it immediately becomes clear that Dexxter is not just a data entry app, but a smart guide that protects sole proprietorships from missteps. Thanks to built-in “guardrails,” the data flows into your office almost perfectly:
- Smart VAT logic: As soon as an entrepreneur sends an invoice to a company within the EU, Dexxter automatically applies reverse charge VAT and blocks other options. Errors in the VAT listing are thus eliminated at the source.
- The Investment Trigger: Does a client record an invoice of, for example, €1,000 as an ordinary expense? The software immediately prompts: “Is this not an investment?”. The client is then directed to the learning center to learn more about depreciation.
- Compliant daily receipts: The digital daily receipts book forces entrepreneurs to register every day, including closing days, fully in accordance with Belgian legislation.
Compliance as a standard, not a concern
In the post-Peppol era of 2026, uniform digital delivery is crucial for the efficiency of your accounting firm. Dexxter acts as a filter. Duplicate entries are recognized, and the timeline provides automatic reminders for VAT filings and advance payments.

“It seemed so chaotic in my head, but it’s actually child’s play,” testifies starter Yannick. He feels safe knowing the system checks him, while file manager Marc monitors in the background via the free portal.
The ultimate guarantee
For the partner seeking maximum security, Dexxter also offers penalty protection. This covers fines in case of calculation errors by the software, allowing you to delegate control over daily input to the client with peace of mind.
