Peppol – Setting Dexxter as e-invoicing software to 120%

I have the same question. Can I adjust this retroactively for the previous year's subscription?

I was searching for that too and found an other blog post where Dexxter itself provides an answer. I'll rephrase it here:

Go to the Reports / Income & expenses menu.

At the top right, there is a "manual input" button where you can add a separate entry (cost category, amount, description). There, you can enter an additional 20% for the cost price of Dexxter or for other costs that can be deducted at more than 100%.

In the context of retroactive adjustments for 2024, that would also be the solution.

Thanks for the tip!
