Businesses often receive services or use resources before they actually pay for them. For example, employees may earn wages at the end of a month, but the company may not pay those wages until the following month. The expense has already occurred even though the cash payment has not.

This is where an accrued expense adjusting entry becomes important.

An accrued expense is a cost that a business has incurred but has not yet paid or recorded in its accounting records. Recording the adjustment ensures that expenses are recognized in the correct accounting period. This supports accurate financial reporting and gives business owners a clearer view of what they actually owe.

Understanding this process is also an important part of general bookkeeping, especially for businesses that use accrual accounting.

What Is an Accrued Expense Adjusting Entry?

An accrued expense adjusting entry is a journal entry made at the end of an accounting period to recognize an expense that has been incurred but has not yet been recorded.

The basic entry usually involves two accounts:

• Debit: Expense account
• Credit: Accrued liability or payable account

For example, suppose a company owes employees $3,000 in wages for work performed during September. The employees will receive payment in October.

At the end of September, the company can record:

Debit: Wages Expense — $3,000
Credit: Wages Payable — $3,000

The debit increases the expense reported for September, while the credit recognizes the amount the business owes.

When the wages are eventually paid, the payable is reduced.

Why Adjusting Entries Are Necessary

Without adjusting entries, financial statements can show an incomplete picture of a company's financial position.

If an expense belongs to September but is not recorded until October, September's expenses will be understated. At the same time, October's expenses may appear higher than they should be.

This conflicts with the basic principle of accrual accounting, which generally recognizes revenues and expenses in the periods to which they relate rather than simply when cash changes hands.

Accurate adjustments can help businesses:

• Report expenses in the correct period
• Present more accurate liabilities
• Calculate a more realistic profit or loss
• Improve monthly financial reporting
• Support better budgeting and cash-flow planning
• Reduce bookkeeping discrepancies

Common Examples of Accrued Expenses

Accrued expenses can occur in many areas of business accounting. Some of the most common examples include:

Employee Wages

Employees may work several days before the accounting period ends while payday occurs later. The business needs to recognize the wages earned during the current period.

Interest Expense

A company may owe interest on a loan that has accumulated over time but will not be paid until a later date.

Utilities

Electricity, water, internet, or other services may be used during one accounting period while the bill arrives or is paid during the next period.

Professional Services

A business may receive accounting, legal, consulting, or other professional services before receiving an invoice.

Taxes and Other Obligations

Certain taxes and business-related costs may accumulate before the actual payment is made.

The specific accounts used depend on the type of expense and the company's accounting system.

How to Create an Accrued Expense Adjusting Entry

Creating the adjustment becomes easier when you follow a consistent process.

1. Identify the Expense

First, determine what cost has been incurred but has not yet been recorded.

For example, a business may have received consulting services worth $1,500 during the month but has not received an invoice.

2. Determine the Amount

Estimate or calculate the amount that belongs to the current accounting period based on available documentation.

The amount should be supported by reasonable records whenever possible.

3. Debit the Expense

The applicable expense account is debited to recognize the cost.

For the consulting example:

Debit: Consulting Expense — $1,500

4. Credit the Liability

A corresponding liability is credited because the business now has an obligation to pay.

Credit: Accrued Expenses Payable — $1,500

5. Review the Adjustment

After recording the entry, review the supporting documentation and accounting records to make sure the amount and accounts are appropriate.

Good documentation is especially important when multiple adjusting entries are prepared each month.

What Happens When the Expense Is Paid?

Suppose the $1,500 consulting expense is paid in the following month.

The payment entry would generally reduce the liability rather than record the expense again:

Debit: Accrued Expenses Payable — $1,500
Credit: Cash — $1,500

This prevents the same expense from being recognized twice.

A common bookkeeping problem occurs when an accrued expense is recorded initially and then the entire payment is later posted directly to an expense account. That can duplicate the expense and distort the financial statements.

Common Mistakes to Avoid

Accrued expense accounting is straightforward once the process is understood, but several mistakes can create problems.

Recording the Expense in the Wrong Period

The expense should generally be matched with the period in which it was incurred. Recording it too early or too late can affect reported profitability.

Forgetting the Liability

Recording only the expense without recognizing the corresponding obligation can understate liabilities.

Double-Recording the Expense

Businesses sometimes record an adjusting entry and then record the later payment as a new expense. This can cause expenses to be overstated.

Using Unsupported Estimates

Accrued amounts should be based on reliable information whenever possible. Poor estimates can create inaccurate financial statements.

Failing to Reverse Entries

Some businesses use reversing entries at the beginning of the next accounting period to simplify the later transaction. Whether a reversing entry is appropriate depends on the company's accounting procedures.

How Bookkeeping Helps Prevent Accrued Expense Errors

Consistent general bookkeeping provides the foundation for identifying expenses that have been incurred but not yet paid.

A regular month-end closing process can include reviewing unpaid invoices, payroll records, loan statements, contracts, utility usage, and recurring services. These reviews can help identify obligations that need to be recognized before financial statements are finalized.

Accounting software can also help organize payable balances and recurring transactions, but software does not replace the need for proper review. Someone still needs to verify whether an expense belongs to the current reporting period and whether the amount is reasonable.

A Simple Way to Remember the Entry

The basic concept can be summarized as:

Expense incurred but not paid = recognize the expense + recognize the liability.

So, in a typical situation:

Debit Expense
Credit Accrued Liability

When payment occurs later:

Debit Accrued Liability
Credit Cash

The exact account names may vary depending on the business and accounting system.

Final Thoughts

An accrued expense adjusting entry helps businesses report expenses and liabilities in the appropriate accounting period. Whether the obligation relates to wages, interest, utilities, professional services, or another cost, recording the adjustment properly can make financial statements more accurate.

The process is simple in principle: recognize the expense when it is incurred, record the related liability, and then clear that liability when payment is made.

For businesses managing monthly financial records, consistent general bookkeeping, careful account reconciliation, and a structured month-end review can make these adjustments easier to identify and maintain. Accurate records ultimately give business owners better information for understanding profitability, obligations, and cash-flow needs.
