Chris Zelinski started Green Scene Landscaping (GSL) five years ago, offering a wide range of lawn care services. In the early years of the business, Chris kept up with his customers, price quotes, service dates, and payment information using his memory and some paper-based records. As the business has grown, Chris has begun to realize that a better system for tracking customers is required. After considering several options, he has decided to replace his current system with an Excel workbook.
Chris has begun to create the workbook with a worksheet for customer information and a worksheet for payment information. The Customer worksheet contains a number of fields which are described in Figure 1.

TOTAL WEEKLY CHARGES Total of standard and additional charges
