OSS is the One-Stop-Shop, so if you sell across the EU, you could declare your VAT to the Dutch, and they will forward the needed amounts to member states.

"verlegde btw" seems to be the reverse-charge mechanism.

It's really hard to find good accounting software

Thanks! It looks good, I guess better than my hardcore plain text accounting. I wonder, do they support VAT returns with OSS and Reverse Charge as well?

How are you handling your taxes, Michiel?

I also see that you are in the Netherlands 🇳🇱 👋

Life hack: don't waste money on unnecessary things 🤷‍♂️
