Accrual-basis accounting is a concept in which expenses are recorded when incurred, not when amount is paid. 1. ACCRUALS / PROVISIONS: All expenses incurred to generate revenues must be recognized in the same period as the related revenues. A provision is an amount that you put in aside in your accounts to cover a future liability. 2. PREPAID: A type of asset that arises on a balance sheet as a result of business making payments for goods and services to be received in the near future.
