IQ Books is an AI-native UK ledger that does the bookkeeping for you.

I connect Claude to your own Oracle Cloud EPM pod and help the people who run EPM check jobs, run rules, load data and read metadata or a slice of numbers.

Risky writes ask for confirmation first, with a preview of what will change. On a production pod that is every write. The activity log holds no cell values.
