Petty cash imprest system
Definition
A petty cash imprest system is a method where a fixed float is kept for small expenses and topped up by exactly the amount spent, backed by vouchers.
How does an imprest system work?
- Set a float amount and name one custodian.
- Pay small expenses only against a signed voucher and receipt.
- At any time, cash in hand plus vouchers equals the float.
- Reimburse the total of vouchers to restore the float, after review.
Why use the imprest method?
It makes shortages visible quickly, because the count must always reconcile to the float. The Petty Cash Operations and Disbursement Control course teaches the controls, and spending ends up in the accounts payable and expense records.
