What a bank reconciliation proves
A reconciliation shows that your books and the bank agree on how much money is in the account, and explains every reason they don't on a given day. Two balances are adjusted until they meet:
- Adjusted bank balance = statement ending balance + deposits in transit − outstanding checks.
- Adjusted book balance = books ending balance ± items on the statement you haven't recorded yet (bank fees, interest, automatic payments).
When the two adjusted balances are equal, the account is reconciled. The bank-only items then become entries to post in your books, and the outstanding items are what to watch for on next month's statement.
Getting the right files
The bank statement
Use the statement for the month you're reconciling. A PDF works directly; a CSV, Excel or QBO download from online banking works too, as long as it covers the same dates. When the file includes the ending balance (PDF statements and QBO/OFX downloads usually do), it's filled in for you.
Your books
- QuickBooks Online: open the account's register, or run a Transaction Detail by Account report for the bank account, filtered to the statement period, and export it to Excel.
- QuickBooks Desktop: run a Transaction Detail or the account's register report for the period and export it to Excel or CSV.
- Xero: export the Account Transactions report for the bank account.
- A spreadsheet: any file with a date, a description and an amount (or debit and credit) column.
Working through the difference
- Start with the two lists of unmatched items. Most are genuine: a deposit on the 31st, a check written last week, the monthly service fee.
- Look for pairs: an unmatched book item and an unmatched bank item with similar amounts, such as $45.10 and $41.50. That's a typo in the books.
- If the same item appears twice on the books side, it was probably entered twice, or imported and also entered by hand.
- If dates are the issue (checks clearing weeks later), widen the matching window.
- When the difference is zero, download the Excel or PDF report and keep it with the month's records.
