What Is Bank Reconciliation and How Does It Work

Bank reconciliation is an essential accounting process for any business that wants to keep its finances organized. It involves comparing transactions in the company’s accounting records with those shown on its bank statements to make sure the two sources align.

This process supports accurate, transparent financial records, helping finance leaders make informed decisions and identify discrepancies, errors, or irregularities.

In this article, we explain the bank reconciliation process, why it matters, and how to apply it through a practical example.

Although bank reconciliation may seem like a straightforward technical task, it can become a significant challenge for fast-growing businesses, especially those processing high transaction volumes. The process becomes even more complex when a company operates across borders.

Bank reconciliation is essential to maintaining a company’s financial health. It gives finance leaders a clear, accurate view of the business’s financial position and serves as an important financial control.

Some of its key benefits include:

Financial Accuracy

Identifying and correcting errors or omissions in accounting records helps ensure that income and expenses are recorded correctly, preventing discrepancies or irregularities from affecting financial reports.

Asset Protection

Reconciling transactions helps teams quickly detect fraud or unauthorized activity and verify that bank transactions are legitimate and supported by documentation. It also creates a detailed record for future audits.

Informed Decision Making

Reconciliation provides a clear, up-to-date view of the company’s cash position. Accurate data supports financial planning, helping management anticipate funding needs and make well-informed decisions.

Bank reconciliation also helps businesses:

• Improve operational efficiency by reducing the time spent resolving financial inconsistencies.
• Build trust with partners and investors by demonstrating strong financial controls.
• Support compliance with legal and regulatory requirements and reduce the risk of penalties related to accounting irregularities.

At a high level, bank reconciliation aims to maintain accurate accounts and financial records, identify and resolve errors or discrepancies promptly, and strengthen financial control. It helps verify that reported income and expenses are legitimate and supported by documentation, while detecting omissions, incorrect entries, or unauthorized transactions that may indicate fraud.

Making bank reconciliation a priority also supports a culture of transparency and financial accountability. Incorporating it into routine operations helps businesses produce more accurate, reliable financial reports and meet applicable accounting and legal requirements. Together, these practices strengthen stakeholder confidence in the company’s financial management

1. Gather Your Documents

Start by collecting all documents that reflect the company’s financial transactions.

Documents Needed for Bank Reconciliation:

Bank statements

Bank statements provide a detailed record of transactions processed through the company’s accounts during a specific period. Because they are issued by the bank, they serve as a primary source for comparing and verifying the company’s financial records.

Accounting records

These include internal records of income, expenses, checks issued, deposits made, and the previous month’s bank reconciliation. They are typically maintained in the general ledger or accounting software. Review the previous period’s reconciliation to confirm the ending balance and determine whether any discrepancies are new or carried over from earlier periods.

Supporting documents

You may also need payment confirmations, receipts, credit and debit memos, cash reports documenting cash transactions, and payment card statements.

Document Collection Challenges and Solutions

Managing multiple bank accounts is one of the main challenges at this stage. It can make document collection more difficult and increase the risk of errors and delays. Automation can help address this challenge. Prometeo’s treasury management solution enables businesses to centralize and consolidate information from their bank accounts in one place, supporting accurate, efficient reconciliation with access to real-time information.

2. Compare Transactions

Once you have gathered the necessary documents, compare the transactions on the bank statements with those in the accounting records. Follow these steps:

Verify Transactions

Check each transaction in the general ledger against the corresponding bank statement entry. Review dates, amounts, and descriptions to verify consistency, and flag any items that have not yet appeared on the bank statement.

Identify Discrepancies

Review all incoming and outgoing transactions, paying close attention to differences between the accounting records and the bank statement. Investigate each discrepancy and resolve it as appropriate.

A spreadsheet or specialized software can make the comparison easier. Create columns for the date, description, and amount of each transaction in both the accounting records and the bank statements. Mark matched transactions, then focus on unmatched items that may indicate errors or differences requiring further review.

3. Identify Discrepancies and Their Causes

Discrepancies are common during bank reconciliation and must be reviewed to maintain accurate financial records. Examples include duplicate or missing transactions, calculation errors, and payments recorded as received even though collection is still pending.

Understanding the cause of each difference is essential to resolving it correctly and preventing larger accounting issues.

The main causes include:

Human Error

Manual errors are common, especially when accounting records are maintained by hand or in spreadsheets, which can lead to inconsistent data.

Missing Entries

Transactions may go unrecorded because they were overlooked or lacked supporting documentation, creating differences between the books and the bank statements.

Timing Differences

Payments made at month-end may not appear until the next bank statement, creating a temporary difference between the company’s records and the bank’s records.

4. Correct Errors

Once you have identified the discrepancies and their causes, correct any errors to maintain accurate, reliable financial records. Unresolved errors can distort the company’s financial position, undermine financial management, and affect decision-making and tax compliance.

Use the following approaches to address discrepancies:

Adjust Accounting Records

If transactions are missing or recorded incorrectly in the books, make the appropriate adjustments. This may involve adding omitted transactions, correcting amounts, or updating dates. Document every adjustment to maintain a clear record of the changes.

Resolve Bank Errors

Sometimes the error is on the bank statement. If you identify an error made by the bank, such as a duplicate or incorrect charge, contact the bank to request a correction. Follow up and confirm that the corrected transaction is reflected in the bank’s records and the relevant statement.

Reconcile Outstanding Transactions

Outstanding checks and deposits in transit can create temporary differences between accounting records and bank statements. Track these items, classify them appropriately, and reconcile them in the following period.

Document Discrepancies

After making the necessary adjustments, document each discrepancy, its cause, and the corrective action taken. This creates a record for future audits and helps prevent similar errors from recurring.

5. Review and Confirm

The final step is to review all adjustments and corrections. Confirm that the adjusted book balance matches the bank balance after accounting for outstanding transactions.

Confirm the Ending Balance

Once errors have been corrected and discrepancies reconciled, confirm that the ending balances agree after the relevant reconciling items are taken into account. This helps ensure that unresolved errors do not affect future financial reporting.

Close the Accounting Period

After completing the reconciliation and verifying the records, you can close the accounting period. This step confirms that income and expenses have been recorded correctly and that the financial information is reliable.

Retain Reconciliation Records

Keep all documents used in the reconciliation process, including bank statements, accounting records, adjustments, and any other relevant supporting documentation. These records provide an audit trail and a reference for future reviews.

A company starts with the following balances:

• Balance in the company’s accounting records: $195,000
• Balance on the bank statement: $194,000

Total difference: $1,000

Step 1: Gather Documents

The company collects:

• Its bank statement for August.
• Its accounting records.
• Payment confirmations, credit and debit memos, and receipts for the month.

Step 2: Compare Transactions

The comparison reveals the following discrepancies:

• A $2,000 check issued by the company that has not yet appeared on the bank statement.
• A $1,500 bank fee that has not been recorded in the books.
• A $1,500 customer payment that has not yet appeared in the bank account.

Step 3: Identify the Causes

The discrepancies have the following causes:

• The $2,000 check was issued and recorded in the books, but the payee has not yet cashed it. As a result, it has not been deducted from the balance on the bank statement.
• The bank charged a $1,500 fee that was not recorded in the books, creating a difference between the accounting records and the bank statement.
• The $1,500 deposit was made on August 31 and recorded in the books that day. However, it has not yet been reflected in the bank account balance.

Step 4: Correct Errors

Here is how each item is handled:

Outstanding Check of $2,000

The check is already recorded in the books but has not yet cleared the bank. No adjustment to the books is required. Record it as an outstanding item and check it against the next bank statement.

Unrecorded Bank Fee of $1,500

The bank charged a $1,000 fee that had not been recorded. The fee is recorded as an expense in the books, reducing the book balance to $19,500.

Deposit in Transit of $1,500

The deposit is recorded in the books but has not yet appeared on the bank statement. No adjustment to the books is required. Record it as a deposit in transit and verify it against the next bank statement.

Step 5: Review and Confirm

After these adjustments, the balances are reconciled as follows:

Adjusted Book Balance

• Starting book balance: $195,000
• Less the $1,500 bank fee: $195,000 − $1,500 = $193,500

Adjusted Bank Balance

• Starting bank statement balance: $194,000
• Add the $1,500 deposit in transit: $194,000 + $1,500 = $195,500
• Subtract the $2,000 outstanding check: $195,500 − $2,000 = $193,500

The adjusted balances now match after accounting for the outstanding check, unrecorded bank fee, and deposit in transit. Although some transactions have not yet appeared on the bank statement, they have been identified and will be monitored in the next period. This keeps the company’s financial records organized and ready for future reviews and decisions.

Bank reconciliation offers several benefits and presents challenges that businesses should consider when maintaining effective financial controls.

Benefits

Error Detection

Reconciliation helps identify accounting errors, such as duplicate entries or incorrect amounts, so that transactions are recorded accurately.

Fraud Prevention

It helps identify unauthorized transactions and protect company assets. Regular account reviews can reveal suspicious activity before it becomes a larger problem.

Accurate Financial Information

Reconciliation helps financial information reflect the company’s actual position, supporting informed decisions. Accurate, current data is essential for financial analysis, budgeting, and strategic planning.

Financial Control

A clear view of the company’s financial position supports better resource management. Knowing the actual balances of bank accounts helps prevent overdrafts and improve cash flow management.

Tax Compliance

Accurate records are essential for meeting tax obligations and reducing the risk of penalties. Regular reconciliation helps ensure that income and expenses are recorded correctly for tax reporting.

Challenges

Time and Resources

The process can be labor-intensive and time-consuming, particularly when performed manually. Businesses need trained staff to carry out these tasks, which can increase costs.

Human Error

Manual data entry increases the risk of errors and can complicate reconciliation. A small typing mistake can create a significant discrepancy in financial records.

Timing Differences

Accounting and bank records may temporarily differ because of processing or posting delays. These differences can create confusion and make it harder to maintain an accurate view of the company’s finances.

Technical Complexity

Reconciliation can become complex for businesses with multiple bank accounts and high transaction volumes. Managing large amounts of data requires efficient systems and well-trained staff.

As businesses expand internationally, bank reconciliation becomes more complex. Managing accounts and tracking payments across countries can increase manual work and make discrepancies harder to resolve.
