minimal amount of money kept on hand by a business entity to meet small expenditures (e.g., postage, taxi fare). One individual (custodian) should be responsible for the fund to maintain control. The fund is available currency and is periodically reimbursed, usually monthly. At any point, the fixed amount of the fund consists of the total currency left and the vouchers (receipts) for the expenditures made. The vouchers should be perforated so they will not be used again.
