New Release Ltd provides pay-TV services across Australia. To subscribe to New Release, customers call a hotline number, select the package they require, and provide a credit card number, to allow automatic payment of the monthly fee. Approximately 600 new subscribers sign up each month.

There are no contracts and no payment accepted other than via credit card. There is no hard-copy documentation generated in relation to the sale- hotline staff enter the customer's details directly into the computer, which then generates the relevant journal entries and postings to the ledger.

From the discussions with management, you believe this system has not changed since you tested it during last year's audit when you placed a high level of reliance on the controls and found only one minor deviation.
