Thank you! Well, I built it in a way that the format is kinda universal – expenses are categorized but not with tax codes. Instead I am using labels like e.g. 'Cloud Infra & Hosting'. Plus apart from the basic infos I even extract things like reverse charge y/n or validate VAT IDs to make it as easy as possible for my tax advisor.

So it will not file your taxes for you but it prepares the raw data for your tax guy in a way that they have minimal effort and you can save quite substantially on the bookkeeping part. I'm in Austria and it is a bit cheaper here but also quite costly. Now I only pay for the tax filing, annual accounts and consulting when I need it.
