Advantages of Imprest System of Petty Cash Book:
1. It relieves the cash book and the Chief Cashier of the burden of recording tiny and frequent payments.
2. Commission of fraud is reduced as the Chief Cashier verifies petty cash book along-with vouchers and the Petty Cashier is more responsible.
3. This method is very scientific and labour saving. The total expenditure under each column can easily be ascertained and only the periodical totals of each column need be posted to the ledger.
