How to ensure that sole proprietorships book documents correctly

The biggest hurdle for accounting firms in letting clients book their own entries is often fear. Fear that the business owner will select incorrect VAT rates, record investments as ordinary expenses, or simply lose track of deadlines. But what if software makes those errors physically impossible?

Fiscal safeguards at the source

In practice, Dexxter turns out to be more than just a data entry app; it’s a smart guide that helps sole proprietors avoid mistakes. The account manager at Carbofisc confirms that “Dexxter’s AI is incredibly smart” and that, thanks to its rigorous process, it’s nearly impossible to make mistakes or overlook steps.

Thanks to built-in “safeguards”, the data flows into your office almost completely error-free:

• Smart VAT logic: As soon as an entrepreneur sends an invoice to a company within the EU, Dexxter automatically applies VAT reverse charge and blocks other options. Errors in the VAT listing are thus eliminated at the source.
• Investment trigger: Does a client book an invoice of, say, €1,000 as a regular expense? The software immediately prompts: “Isn’t this an investment?” The client is instantly redirected to the learning center to learn more about depreciations.
• Compliant daily receipts: The digital daily receipts book requires business owners to record entries every day, including closing days, in full compliance with Belgian law. This eliminates the infamous “hieroglyphics” found in handwritten receipts books.

Compliance as the norm rather than a concern

In the post-Peppol era of 2026, uniform digital submission will be crucial to the efficiency of your accounting firm. Dexxter acts as a filter in this process. Duplicate entries are detected, 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,” says first-time entrepreneur Yannick. He feels secure knowing that the system keeps him in check, while account manager Marc monitors things in the background through the free portal.

The ultimate guarantee

For partners seeking maximum peace of mind, Dexxter also offers penalty protection. This covers penalties resulting from any calculation errors made by the software, allowing you to delegate control over daily data entry to the client with complete confidence.
