Costs for 2023 in the 2024 financial year

In the run-up to starting your business, you are indeed allowed to include investments from the previous year.https://dexxter.be/kan-ik-purchases-inbrengen-from-voor-de-opstart-als-zelfstandige/ If you want to delete Expense, you can simply delete it in Dexxter by clicking on the three dots under 'Actions'.

Thank you for your answer and the tip. It is clear that I can include investments, but I am not entirely sure about car insurance for 1 year. I only noticed the delete option later, as my screen was too small and I did not see the three dots :-).
