The accounting process for office or store supplies is similar to the procedure followed for prepaid or unexpired expenses. Specifically, they are initially recorded as assets by debiting the office or store supplies account and crediting the cash account.

At the end of the accounting period, the cost of supplies used during the period becomes an expense and an adjusting entry is made.
