How to Catch Up on Months of Unreconciled QuickBooks

By Philip Segar ยท Published November 10, 2026

To catch up on QuickBooks, bring in every bank and card transaction, categorize the backlog month by month, reconcile each month to the statement, then fix duplicates and uncategorized items. For a small business this is usually priced per month of backlog. At PMD Financial, cleanup is typically $150 per month of catch-up work.

Signs your books need cleanup

  • Bank and credit card accounts haven't been reconciled in months.
  • Large balances sit in Uncategorized Income, Uncategorized Expense or Ask My Accountant.
  • The QuickBooks bank balance doesn't match the bank statement.
  • Transactions show up twice because the bank feed and manual entries both recorded them.
  • Your tax preparer asked for a profit-and-loss statement and you weren't sure the numbers were right.

The catch-up process

  1. Gather statements. Download every bank and credit card statement for the months you're behind.
  2. Check the starting point. Find the last month that was reconciled correctly. Everything after it is the backlog.
  3. Bring in the transactions. Use the bank feed where it covers the period and upload statement files where it doesn't.
  4. Categorize month by month. Set up bank rules for recurring vendors so the same payee lands in the same account every time.
  5. Reconcile each month. Match the ending balance in QuickBooks to the statement before moving to the next month.
  6. Clean up what's left. Remove duplicates, clear uncategorized accounts and match transfers between accounts.
  7. Review the reports. Run a profit-and-loss statement and balance sheet and check that they make sense.

What cleanup costs

Pricing depends on how many accounts you have, how many transactions you have each month and how far behind the books are. At PMD Financial, cleanup is typically $150 per month of catch-up work, and a free consultation is required to confirm your fixed price. Ongoing monthly bookkeeping is $250 a month. See bookkeeping for details.

When to get help

If you're more than a few months behind or tax season is close, handing the backlog to a bookkeeper is usually faster than learning the cleanup process yourself. Clean books also make your tax return quicker to prepare.
