Accrual accounting in plain English

Imagine you deliver a service in December and the client pays in January. On the accrual basis the revenue belongs to December, because that is when you earned it. On the cash basis it would land in January. Accrual accounting follows the matching principle: expenses are matched to the revenue they helped earn.

Worked example

In December a business uses 400 of electricity but the bill arrives and is paid in January. Under accrual accounting the 400 is a December expense and a liability (accrued expense) at 31 December.
