Prepare the design and prototype of the printed Sales Invoice that will be printed upon completion of the sales transaction at Holiday Travel Vehicles. This will be the document that the customer takes with him/her summarizing the sale. Also, design and prototype an output report from the system that provides the owner of Holiday Travel Vehicles information about the prior week’s sales activity. This report should be available in two forms: one that groups the sales by vehicle manufacturer, and the other that groups the sales by salesperson. The owner want to use the reports to quickly assess the sales performance of the various vehicles offered for sale and the performance of the various salespeople on staff.
