Based on the tests of controls and other Information Technology General Controls (ITGC) testing. your firm has concluded that the data files supplied to you for your procedures are complete and accurate. The conclusion was based on tests of controls over data input risks, including all relevant data elements (e.g., invoice date), data integrity risks, and the relevant automated application controls. However, it is also important to confirm that the data, once imported into IDEA or Tableau, was transferred into the technology tool in a complete and accurate manner prior to working with the data within the technology tool. Import all supplied data into IDEA and then reconcile the data with the supplied trial balance and check figures from the case. Simply stated, you must check that the data has been transferred in a complete and accurate manner at each step in the process. Thus, to ensure that you are working with the set of transactions and balances that the client used to calculate Sales Revenue and Accounts Receivable, answer the following questions: a. What are the total number of valid sales that comprise the $84,867,855 sales revenue shown on the trial balance as of 12/31/2017? b. What are the total number of unpaid invoices that comprise the $11,988,886 gross accounts receivable balance shown on the trial balance as of 12/31/2017?
