Imagine a freelance graphic designer who completes a big project for a client in December. The designer sends the invoice, but the client doesn't pay until January. If the designer only recorded money when it hit their bank account, their December books would show zero income from that project, and January would look unusually profitable. This isn't an accurate picture of when the work was actually done.

This is where the accrual concept comes in. It's a core principle of accounting that aims to match revenues and expenses to the period in which they occur, not when cash changes hands. This method gives a more realistic view of a company's financial health.

This principle is put into practice using two main types of adjustments: accruals and prepayments. They are essential for creating accurate financial statements at the end of an accounting period.

An accrual is a journal entry to record a revenue that has been earned or an expense that has been incurred, even though no cash has been exchanged yet. Think of it as accounting for what's happened, but hasn't been paid for.

Accrued Expenses

These are expenses a business has incurred but hasn't yet paid. A classic example is employee salaries. Let's say a company's pay period ends on December 31, but payday isn't until January 5. The company owes its employees for the work they did in December. To reflect this on the December financial statements, the company records an accrued expense.

The journal entry on December 31 would look like this:

This entry increases the Salaries Expense for the period and creates a liability called Salaries Payable, showing the company's obligation to pay its employees.

Accrued Revenue

This is the flip side: revenue a business has earned but hasn't yet received cash for. Imagine a consulting firm that provides $2,000 worth of services to a client in March but doesn't send the invoice until April 1. To accurately report its March earnings, the firm must record the revenue it earned.

The journal entry on March 31 would be:

This increases an asset account, Accounts Receivable (money owed to the company), and increases Service Revenue for the period.

Prepayments occur when cash is paid or received before the service is rendered or the expense is incurred. It's the opposite of an accrual. These transactions also require adjustments to ensure expenses and revenues are recognized in the correct period.

Prepaid Expenses

A company often pays for certain expenses in advance. A common example is insurance. Suppose a business pays $12,000 on January 1 for a full year of insurance coverage. When the payment is made, the entire $12,000 is not an expense for January. Instead, it's an asset because it represents a future benefit—12 months of coverage.

The initial journal entry on January 1 is:

At the end of each month, the company must record the portion of the insurance that has been "used up." Since the policy covers 12 months, the monthly expense is $1,000 ($12,000 / 12). An adjusting entry is made on January 31 to recognize this.

This entry moves $1,000 from the asset account (Prepaid Insurance) to an expense account (Insurance Expense). This process is repeated each month until the prepaid asset is fully depleted.

Unearned Revenue

Sometimes a business receives cash from a customer before providing the goods or services. This is called unearned revenue (or deferred revenue). It's a liability because the business owes the customer a service or product. For example, a magazine publisher receives $120 on July 1 for a one-year subscription.

The initial journal entry on July 1 is:

As the publisher delivers the magazine each month, it earns a portion of that revenue. The monthly amount earned is $10 ($120 / 12). At the end of July, the company makes an adjusting entry to recognize the revenue it has earned.

This entry reduces the liability (Unearned Subscription Revenue) and increases the revenue (Subscription Revenue) for the period.

Accruals and prepayments directly affect both the income statement and the balance sheet. By recording revenues when they're earned and expenses when they're incurred, these adjustments ensure the income statement provides an accurate picture of profitability for a specific period.

On the balance sheet, they create accounts like 'Accounts Receivable', 'Salaries Payable', 'Prepaid Insurance', and 'Unearned Revenue'. These accounts ensure the balance sheet accurately reflects the company's assets and liabilities at a specific point in time. Without these adjustments, a company's financial health could be easily misunderstood.
