Accrual accounting

In accrual accounting, revenue is recognized when it is earned (not when cash is received), and expenses are recognized when they are incurred (not when paid). This is the opposite of cash-basis-accounting, which only counts transactions when money changes hands. Accrual accounting is mandatory for public companies under GAAP and IFRS because it provides a more accurate picture of economic performance: the income statement shows profit from the work done in the period, regardless of the timing of cash.

The example that explains it all

A consulting firm signs a three-year contract in January for $300,000, with payment due at year-end.

Under accrual accounting: The firm recognizes $100,000 of revenue in January when the contract is signed and the service obligation is clear. Accounts receivable on the balance sheet rises by $100,000. When the client pays at year-end, cash increases and accounts receivable decreases — the income statement is unchanged because the revenue was already recognized.

Under cash-basis accounting: The firm recognizes zero revenue in January. It recognizes $300,000 when the cash arrives at year-end.

Which is more useful? Accrual accounting reveals that the firm earned $100,000 in the period (the correct economic truth). Cash accounting obscures performance. If the firm earned identical revenue all year, cash accounting would show zero, zero, zero revenue in the first three quarters and a huge spike in the fourth. Accrual accounting shows steady progress.

The matching principle

Accrual accounting rests on the matching principle: match expenses to the revenue they helped generate. If a sales commission is earned when the sale is made, it is expensed then, not when paid. If a company buys a three-year insurance policy, it doesn’t write off the entire cost in year one; it spreads it across three years (an accrued expense or prepaid expense).

This principle ensures the income statement shows true economic profit: revenue minus the costs incurred to generate it.

Key accrual mechanics

Accrual accounting introduces several accounting items that don’t exist in cash accounting:

• Accounts receivable — amounts customers owe for goods or services delivered.
• Deferred revenue — cash received before the service is delivered.
• Accrued expenses — expenses incurred but not yet paid.
• Prepaid expenses — cash paid in advance for future services.
• Depreciation — the spread of an asset’s cost over its useful life.

Each of these bridges the gap between when the economic event occurs and when cash changes hands.

Why cash flow statement exists

Because accrual accounting and cash can diverge, public companies must report both an income statement (accrual) and a cash flow statement. The income statement shows profit; the cash flow statement shows whether profit converted to cash.

A company can be profitable on paper but insolvent in cash (or vice versa, though less commonly). Both pictures are necessary for a complete understanding of financial health.

Accounting choices within accrual accounting

Accrual accounting requires judgment. Two companies can use accrual accounting and still report different profit for the same economic events because they make different accounting choices:

• Revenue recognition: One company recognizes revenue on order; another waits for delivery.
• Depreciation: One assumes a 10-year useful life; another assumes 5 years. Both are using accrual accounting, but depreciation expense differs.
• Allowance for doubtful accounts: One estimates 2% of receivables will not be collected; another estimates 5%.

These choices must be disclosed in footnotes and must be consistent from year to year. But they can move reported earnings, which is why investors focus on footnote-disclosure.

The gap between accrual earnings and cash flow

Because of accrual accounting, operating cash flow can differ significantly from net income. Examples:

• High working capital growth: A growing company must finance accounts receivable and inventory. Net income may be strong, but cash is tied up in balance sheet items.
• Non-cash charges: Depreciation and amortization reduce net income but are not cash outflows. Operating cash flow is higher than net income.
• Stock-based compensation: Companies expense this but don’t pay cash; operating cash flow is higher.

Investors must understand both metrics to assess financial health.
