I tried to evaluate Bigcapital but it's kind of a mess to deploy via self hosting. The docker-compose setup is really hard to break apart, the stack is bizarre (mongo, multiple myql databases, and redis), and the way you do upgrades and migrations left me feeling very uneasy. Additionally, my accountant wouldn't use anything this thing exports from what I can tell. For now I'm sticking with GnuCash, but I have my eye…
What's the most important features in an accounting system in your opinion? Are they of a kind, or are there some killer features on expensive commercial tools that the free fare can't match?
I would say that many businesses just want a desktop based system and web based has security and maintenance requirements they just aren’t interested in.
