How Do I Reconcile a Bank Statement? A Step-by-Step Guide for Businesses

A 2023 survey by PwC found that 68% of financial professionals reported errors in internal records due to delayed or mismatched bank reconciliation. These discrepancies, if left unchecked, can lead to incorrect balance sheets, missed fraud signs, or even failed audits.

  • Do you spend hours matching bank transactions with accounting books manually?
  • Are unreconciled balances creating confusion during monthly or quarterly closings?
  • Is your audit process getting delayed because of unresolved discrepancies?

Bank reconciliation is one of the simplest, yet most powerful ways to maintain accurate financial records. In this guide, we’ll walk through a step-by-step process of how to do it, and how automation platforms like KlearStack make it faster and more reliable.

What Is Bank Reconciliation?

Bank reconciliation is the process of comparing your business’s internal records against the bank statement to make sure both match. It ensures that every deposit, withdrawal, and fee is recorded correctly.

Sometimes, your internal ledger might show a transaction that the bank hasn’t cleared yet, or vice versa. These differences must be reviewed, understood, and corrected.

  • Reconciliation helps detect:
  • Missing or duplicate entries
  • Bank fees or interest not recorded in internal books
  • Fraudulent transactions
  • Errors in recording

Step-by-Step Bank Reconciliation Process

1. Collect the Required Statements

Start by downloading your latest bank statement. Also, export the cash book or transaction summary from your internal system for the same period.

Both records should cover the same date range, preferably a month.

2. Verify the Opening Balance

Ensure that the opening balance in your bank statement matches your internal record. If not, there could be an unresolved discrepancy from the previous period that must be addressed first.

3. Match Transactions One by One

Go through each transaction listed in your books and find its match in the bank statement.

  • Tick each matched entry as “reconciled”
  • Look out for amounts that differ slightly due to rounding or fees

This step is time-consuming, especially for businesses processing hundreds of daily transactions.

4. Check for Unmatched Items

Some entries might appear in one place but not the other. These could include:

  • Outstanding Checks: Issued but not yet cashed by the recipient
  • Deposits in Transit: Sent but not credited by the bank yet
  • Bank Charges or Interest: Shown only in the bank statement
  • This is often where most time is spent, especially when reconciling manually.

5. Adjust Your Internal Records

Make adjustments in your books for bank charges, interest received, or any errors in data entry. If the bank made a mistake, contact them immediately to rectify it.

6. Compare Final Balances

Once all matching and adjustments are done, the closing balances in both your bank statement and internal records should match exactly.

If they don’t, recheck every line to ensure nothing was skipped.

Practical Example of Reconciliation

Let’s say your internal records show $10,000 as the closing cash balance. Your bank statement shows $9,800.

On checking, you find a $200 bank fee not recorded in your books. After entering the fee, both balances match.

This illustrates why reconciliations are important — even small errors compound over time.

If you're still wondering how do I reconcile a bank statement when dealing with high volumes or complex formats, automation becomes your best ally.

Challenges That Make Manual Reconciliation Difficult

Manual reconciliation is still common, but it’s far from efficient. Here’s why:

  • Large Volume of Transactions: Matching hundreds of payments and receipts by hand slows down month-end closings.
  • Multiple Bank Accounts: Reconciliation gets more complex with more accounts or subsidiaries.
  • Human Errors: Mistyping, omission, or duplicate entries can create inaccuracies.
  • Time Pressure: Finance teams are often under tight deadlines, especially during audits or filings.
