This is a company that was just formed at the start of this year (2017).
The founder was my bookkeeper for my TMI at his previous company - this is my 4th year with him.
Strong recommendation. I am not the only non-native Finnish client.
I came to FF a few times to look for a bookkeeper when I first went freelance. I hope this helps someone else;)
