Technical definition
A payment made before the related good or service is consumed, initially recognized as an asset.
How it works
The prepayment represents a future benefit. As time passes or service is received, an adjusting entry reduces the asset and recognizes expense.
Everyday example
A twelve-month $12,000 insurance policy paid on 1 October leaves $9,000 prepaid and $3,000 expense at year-end.
Common pitfall
The full cash payment does not become expense immediately when benefit extends beyond the current period.
