I use `aqbanking-cli` for grabbing transactions from my banks' FinTS/HBCI API and generate a CSV out of that. That CSV then goes through a bit of Python that splits up the entries into transactions. Those get rendered out as `beancount` transactions (but `ledger` works as well, I used that before I switched to beancount) and appended to my actual ledger.

I then use `fava` (a beancount web UI) to fix mistakes, and have another piece of code (this time written in Go, but could be Python/whatever as well) that takes transactions that are generated from my brokerage account and enriches them with data parsed from my brokers' PDF reports (since the FinTS/HBCI info doesn't contain stuff like ISINs or taxes/fees separately).

This is for my personal finances, but I used the same system (minus the brokerage stuff) when I managed the finances of a hackerspace in the middle of Germany for a few years.
