Inside the accountant role we can see and correct your bookkeeping — transactions, the chart of accounts, reconciliations, and reports — while your ownership of the account, and the decision to approve any change, stays with you.
The role exists so an outside specialist can do real bookkeeping without becoming the owner of your business's QuickBooks. In practice that means we can read the file to find what is wrong and, once you approve a written plan, make the corrections a QuickBooks cleanup or catch-up needs. What the role does not do is hand us the keys to the company: we do not become the primary admin, we do not manage your users or subscription, and nothing in your file is changed on our judgment alone. Be clear about one thing: Intuit's help describes no way to narrow what an invited accountant user can do, so the access is broad by design. The controls are therefore the ones you can check — a written plan you approve before any change, our change log, QuickBooks' own audit log, and removal at any time. The free review is the one stage that stays view-only.
