I'm using it in Sweden and GnuCash already has a BAS-12 account template built in. It's pretty much complete and there is no reason to require BAS-17.

I recently started using it so I actually have one unanswered question. Was going to connect to their IRC to find out.

The num column seems to be manual and I'm not sure if it's supposed to be a globally unique value or just a sequence for each transaction (verification) you make.

Sorry if I'm talking out of my ass but I don't know the correct business english to use in these circumstances.
