What is Petty Cash Replenishment?

Petty cash replenishment occurs when funds are added to a petty cash box. The amount of the replenishment should be sufficient to bring the cash balance of the cash box back up to its designated balance. Replenishment is required periodically, as cash payments from the petty cash box are used to pay for incidental expenses. A replenishment transaction is initiated by the petty cash custodian.
