How to Clean Up QuickBooks Online: Step-by-Step for Small Business Owners
If your QuickBooks file is a mess, you’re not alone. Many small business owners get behind, miscategorize transactions, or sync bank feeds without double-checking. The good news? You can clean it up — either on your own or with help. In this post, we’ll walk you through how to clean up QuickBooks Online step-by-step, with real tips that actually work.
If you’re short on time or overwhelmed, Lang Bookkeeping offers a remote catch-up bookkeeping service that handles this for you.
Step 1: Review the Chart of Accounts
Your chart of accounts is the foundation of everything in QuickBooks. Over time, duplicates and unnecessary accounts can cause chaos.
- Archive or merge unused or duplicate accounts
- Group similar accounts under clear headers (like “Advertising” vs. “Marketing”)
- Use only the accounts that match your business operations
Tip: Keep it simple. Too many categories = too much confusion.
Step 2: Check for Duplicate Transactions
If you’ve connected a bank feed and also entered transactions manually, chances are you have duplicates.
- Go to the register and look for repeated payments, deposits, or transfers
- Use filters to identify identical amounts posted twice
- Delete or match duplicates where necessary
Even a few duplicates can throw off your reconciliations.
Step 3: Reconcile Every Bank and Credit Card Account
Reconciliation is how you verify that what QuickBooks says matches your actual bank statements.
- Go to “Reconcile” under the Accounting tab
- Select the account and the correct ending statement balance
- Match transactions line by line to your bank statement
- Fix or flag anything that doesn’t match
If you’ve never reconciled before, start with the oldest month and work forward.
Step 4: Categorize Unreviewed Transactions
Many people leave transactions sitting in “Uncategorized Expense” or “Ask My Accountant.” That’s not sustainable.
- Go to the Banking tab and select the “For Review” section
- Use rules or manual categorization to label everything properly
- Avoid assigning expenses to asset or liability accounts unless you understand why
When in doubt, use an Ask-a-Bookkeeper form to get help fast.
Step 5: Run Reports and Check for Red Flags
After cleanup, verify that your reports make sense:
- Run the Profit & Loss and Balance Sheet reports
- Look for negative numbers that shouldn’t be negative
- Make sure revenue and expense categories are logical and not all lumped under “Other”
Good financial reports = better business decisions. Bad reports = confusion and audit risk.
