Bank reconciliation sounds straightforward: compare your bank statements with your internal records and resolve any differences. But many businesses struggle with the details. Errors creep in, and before long a credit controller may find themselves Googling “how to undo bank reconciliation in QuickBooks Online” just to fix past mistakes.

The truth is, undoing reconciliation is messy, time-consuming, and can throw your bank reconciliation statement out of balance. Cash flow suffers, financial accuracy slips, and poor visibility of your true position follows. The good news?

Most reconciliation problems are preventable. Here, we break down the five biggest mistakes companies make—and how to solve them.

What Is Bank Reconciliation?

Bank reconciliation is the process of comparing a company’s internal financial records with its bank statements to ensure every transaction matches. A bank reconciliation statement highlights discrepancies—such as unrecorded transactions, outstanding checks, or unrecorded bank fees—that need to be corrected for financial accuracy.

Regular bank reconciliations are critical. They protect cash flow, improve financial reporting, and help detect unauthorized withdrawals or potential fraud. Without a consistent reconciliation process, businesses risk misstatements in their financial statements and poor visibility of their true financial position.

Modern reconciliation software, like Kolleno, automates much of this process. By matching transactions quickly, flagging errors, and integrating with general ledger accounts, it reduces manual errors and keeps financial records accurate.

The 5 Biggest Bank Reconciliation Mistakes (And How to Avoid Them)

Even a small oversight in the bank reconciliation process can distort financial records, affect cash flow, and delay financial reporting. Here are the five most common bank reconciliation problems—and how to avoid them.

Biggest Bank Reconciliation Mistakes

1. Failing to Reconcile Bank Statements Regularly

Many businesses treat reconciliation as a once-in-a-while task. This leaves missing transactions, unauthorized withdrawals, and data entry errors undiscovered until it’s too late.

How to avoid it: Build consistent procedures into your accounting system and reconcile regularly. Automated tools like Kolleno make this easier by flagging discrepancies in real time.

2. Overlooking Bank Fees and Interest Payments

Bank fees, overdraft fees, and interest payments often go unrecorded, creating gaps between your internal records and the bank statement. These small amounts add up and distort your closing balance.

How to avoid it: Always review bank statements for unrecorded bank fees and interest payments. Reconciliation software can automatically capture these charges and update your general ledger.

3. Data Entry Errors and Duplicate Transactions

Manual data entry, duplicate payments, or duplicate entries lead to mismatches between the bank reconciliation statement and your internal financial records. Human error is one of the most common bank reconciliation problems.

How to avoid it: Reduce errors by using reconciliation software to automate transaction matching. Tools like Kolleno flag duplicate transactions instantly, protecting financial accuracy.

4. Not Accounting for Outstanding Checks and Transactions

Outstanding checks, electronic payments, or wire transfers that haven’t cleared yet often cause differences between your cash book balance and your bank balance. These unrecorded transactions can mislead decision-making.

How to avoid it: Track all outstanding checks and outstanding transactions carefully. Automated reconciliation tools keep bank records and internal records aligned, even when payments are still pending.

5. Relying on Manual Reconciliation

Manual reconciliation is slow, prone to human errors, and impractical for businesses with high transaction volumes. Manual efforts increase the risk of financial misstatements and make fraud detection harder.

How to avoid it: Move away from manual reconciliation. With reconciliation software like Kolleno, you can match transactions faster, reduce errors, and maintain financial accuracy with far less effort.
