Open Accountant Tools, choose Reclassify Transactions, pick the account and date range you're correcting, check the transactions you want to move, then set the new account and/or class and click Reclassify. It moves everything checked in one pass. Here's the full process, and why it's not visible to every QuickBooks user.
1. Open Accountant Tools. Click the briefcase icon near the top of QuickBooks Online, then choose Reclassify Transactions. This icon only shows up for a user with accountant-level access to the company, not for a standard employee or admin user.
2. Pick cash or accrual basis, then an account type. Choose Profit and Loss accounts or Balance Sheet accounts, whichever side the miscategorized transactions are sitting on.
3. Select the account and date range. Pick the account the transactions are currently posted to, set the date range you're reviewing, and QuickBooks lists every transaction that fits.
4. Check the ones you want to move. Select them individually, or use the header checkbox to grab the whole list at once if everything in it is wrong the same way.
5. Set the new account and/or class. Check Change account to and pick the correct account, check Change class to if class tracking needs fixing too, then click Reclassify.
6. Confirm. QuickBooks moves every checked transaction in one batch, so you're not opening and re-saving dozens of entries individually.
Reclassify Transactions is genuinely useful for the cleanup itself, but it only runs after someone's already noticed a batch of transactions landed in the wrong account or class. It doesn't stop that from happening again next month, and because it lives behind accountant-level access, a bookkeeper or office manager without that role can't run it themselves; they're stuck flagging it for whoever does have access and waiting.
The underlying cause is almost always the same one: a bank rule that's slightly too broad, a new employee entering expenses without knowing the class structure, or a vendor whose charges span more than one department depending on the job. None of those get fixed by reclassifying after the fact, only by catching the category at the point the transaction gets created.
A charge gets assigned its account and class based on which job, client, or department it actually belongs to, pulled from your project or field service tool, instead of a bank rule that guesses from the vendor name alone and gets it wrong for anything split across departments.
Transactions that land in a known catch-all or suspense account get flagged on a schedule, so a reclassify run happens as routine maintenance instead of waiting for someone to notice the P&L looks off months later.
Tell us what keeps landing in the wrong place and why, and we'll tell you if it can be caught before it ever needs reclassifying.
Tell us where the miscategorization is actually coming from, a bank rule, a new hire, a vendor that spans jobs, and we'll tell you whether it's worth fixing at the source. Reclassification is one specific QuickBooks cleanup; we build the same kind of fix for whatever's manual anywhere else in the business too.
Let's talk →Same tool, same process as reclassifying individual transactions: open Accountant Tools, choose Reclassify Transactions, and pick the account whose transactions need to move. "Reclassify accounts" and "reclassify transactions" describe the same action in QuickBooks, moving posted entries from one account or class to another.
It only appears under Accountant Tools, which is visible to users with accountant-level access to the company, typically an external bookkeeper or accountant added through QuickBooks Online Accountant. A standard admin or employee role doesn't see it, even with full permissions elsewhere.
The tool is built for transactions like expenses, checks, and bills posted to an account, not for editing a journal entry's own lines. If a journal entry itself needs correcting, you'll need to open it directly and edit or reverse it rather than running it through Reclassify Transactions.
