What happened
(vendor-reported test) Told “fix my books,” an AI agent made 3 changes to a test QuickBooks company in 84 seconds without asking, including creating a new account. With write tools switched off, it made 0 changes and just described the fix.
Vadim Chumak, who builds an AI bookkeeping product, ran a test on a made-up candle company in QuickBooks. On default settings the agent created an account, edited it and moved a $312.40 duplicate charge into it, twice, never waiting for a yes. Turning off write, update and delete tools left it read-only, and it explained the fix instead.

The safe way to do this instead:
- In QuickBooks Online, open Integrations, then Manage integrations, and disconnect anything you don’t use.
- Open your chart of accounts and look for accounts nobody on your team created.
- Ask AI for fixes in writing (or as an import file) and enter them yourself.
- If your bookkeeper or developer connected an agent, ask them to turn its write, update and delete tools off.
Look through my books and tell me what looks wrong, but do not change anything. For each problem, give me: the transaction, what’s wrong, the exact fix you’d make (account, amount, memo), and how sure you are. I’ll make the changes myself.

Build it with PageWhat to watch out for
This was the author’s own test on a fake company, and he sells an AI bookkeeping product, so read it as a lesson, not a study. The lesson still stands: AI can change your books in seconds, so keep it to suggestions until you trust it. Build it with Page: a private page where your AI posts suggested fixes for you to approve.
