We use ledger with git for distributed accounting work.

Ledger files are plaintext, works really great.

Also, if you encrypt it using GPG with multiple keys, it will allow only a few people to work with it. Probably best to write a script that does it because not everybody understands how GPG works ;-)

Additionally you can use CI for testing and validating the ledger files.

For example we check that expenses don't overrun their allocated budget, and that there is still enough months of runway in left.
