It is important that no cash received is used to make payments. If the internal control over the cash received is unsatisfactory, it could be a nightmare to reconcile and find any cash that has disappeared. To use cash for payments, the petty cash can be used to make cash payments.
It is a good idea to note the range of the receipt numbers issued and the total amount of the cash as well as the total amount of cheques deposited at the back of the deposit slip. This may be helpful for internal control to establish whether all cash and cheques are deposited regularly.
