Two auditors are discussing the audit procedures for sales revenue. Stacy Mendoza believes that the best way to test sales revenue is to select a random sample of recorded sales and to trace these sales back through the system to the supporting documents, noting that all items billed were shipped and that the sales were invoiced at the correct prices. Takai Wong disagrees. He believes that it is better to gather evidence for the sales process by starting with the prenumbered shipping documents and then tracing them forward through the system to the invoice, noting the existence of control procedures and the correctness of the invoice processing.
