You are new to an accounting firm, and you have been assigned to your very first audit. It is an audit of a small company, so the audit team consists of only two people: You, and the in-charge auditor. In larger audits, frequently the first areas that new auditors will work on are inventory and receivables. This company has only a few physical items of inventory, but each of them has a high value, so the in-charge says he will do that himself. However, you are to do the work in the receivables area. He tells you he wants you to do a test for anything that was not billed, but ought to have been billed. Accordingly, he directs you to take a sample of invoices and trace them to the shipping documents and customer orders. Required: Will this be effective in finding items which were not billed, but ought to have been billed? Explain your reasoning
