What Is Accrual Accounting? How It Works and Why It Matters
Accrual accounting records income and expenses when they are earned or incurred, not when cash changes hands. This guide explains how it works, how it differs from cash accounting, and why it is the standard for most businesses.
The Core Principle
Accrual accounting recognises revenue when it is earned and expenses when they are incurred — regardless of when cash actually moves. If you provide a service in December but receive payment in January, accrual accounting records the revenue in December. This gives a more accurate picture of financial performance than simply tracking when money arrives and leaves.
Accrual vs Cash Accounting
Under cash accounting, you record transactions only when cash is received or paid. A small sole trader might use cash accounting for simplicity. Under accrual accounting, you match revenues to the period in which they are earned and expenses to the period in which they relate. A business invoicing in November for December delivery would recognise that revenue in December under accrual accounting, not November.
The Matching Principle
Accrual accounting rests on the matching principle: expenses should be recognised in the same period as the revenues they helped generate. This is why depreciation exists — rather than expensing the full cost of a piece of equipment when it is bought, the cost is spread over its useful economic life to match the periods in which the asset generates value.
Common Accruals and Prepayments
Accruals are expenses incurred but not yet invoiced or paid — an electricity bill for December that arrives in January is accrued at the December year end. Prepayments are payments made in advance for future periods — six months of insurance paid in October represents two months current-year expense and four months prepaid at the December year end.
Why Accrual Accounting Is the Standard
IFRS and UK GAAP both require accrual accounting (with narrow exceptions for very small entities). It provides more meaningful financial statements for stakeholders making investment and lending decisions. Accrual concepts are fundamental to ACCA and CIMA study from the Applied Knowledge level upwards.
