Prepayments in AP

A prepayment (or prepaid expense) arises when a business pays a supplier invoice before the goods or services covered by that invoice have been received or consumed. The payment is made now, but the economic benefit will be received over a future period. Under accrual accounting, the amount paid in advance is not an expense at the time of payment -- it is an asset (a prepaid expense) that is recognised as an expense over the period the benefit is consumed.

Common prepayments in AP include: annual insurance premiums (paid once, benefit consumed over 12 months), software subscriptions paid annually in advance, rent paid quarterly or six-monthly in advance, and membership fees with a 12-month coverage period. For amounts that are immaterial, most businesses expense them immediately regardless of the prepayment nature. For material amounts, the prepayment treatment is required under accounting standards and has a meaningful impact on the accuracy of period financial statements.

Recording a prepayment

When a prepayment invoice is received and paid, the accounting entry is: debit prepaid expense (a current asset account), credit accounts payable or bank. The amount does not hit the expense account yet. Each month, as the prepaid period passes, an amortisation entry recognises the portion of the prepayment that has been consumed: debit expense account, credit prepaid expense. After all months have been amortised, the prepaid expense account balance is zero and the full amount has been recognised in the income statement.

For an annual insurance premium of AU$24,000 paid on 1 January, the monthly amortisation entry is AU$2,000 per month. By 31 December, the full AU$24,000 has been expensed. The prepaid expense account reduces by AU$2,000 each month, from AU$24,000 on 1 January to zero on 31 December. If the accounting period is the financial year (1 July to 30 June), the balance at 30 June would be AU$12,000 -- the portion not yet consumed.

Prepayments and the AP close

Prepayments should be reviewed as part of the month-end AP close to ensure that amortisation is being correctly applied and that no expired prepayments remain on the balance sheet. A prepayment for a subscription that was cancelled mid-year, for example, should be immediately expensed (or a credit note obtained from the supplier) rather than continuing to amortise. Prepayment balances that appear on the balance sheet beyond their intended coverage period are a common audit finding that indicates the amortisation schedule is not being maintained correctly.
