Versioning: I use git to version my ledger file. Preventing regressions: Every time I update with the latest transactions I close the last transaction with an assertion that ensures the balances are correct. (E.g. that the balance on checking is equal to the latest statement, or that outstanding VAT is 0 after paying taxes) I’ve been using ledger for my (small) business for about 5 years now. I’ve a script that calculates all the figures for my quarterly VAT submission by the categories that the tax authority requires (I use tags to label transactions). Importing transactions is still manual work, but given the low volumes it’s not a problem. I do find it frustrating that most banks are still so limited in providing API access to accounts. Invoices are a bit special, I can see outstanding amounts under Assets:Receivables, but haven’t found a good way to track this easily by invoice.
