I am a registered sole proprietor working as a freelancer software engineer in Germany (although an expat).
I don't use business account for small expenses but I use it for:
Rent payment (I also work from home).
Transferring money to my stock broker account and vice-versa.
I transfer it through business account because it's more simpler than Business -> Personal -> Stock broker.
It's also more safer because I keep <2000 EUR in personal account and remaining under business account (where I have disabled debit card).
Question:
Am I allowed to do so?
What if I accidentally make a personal transaction with business account again in the future. What should I do to cover the damage?
