ABSTRACT
Wendy could also use the same data to keep track of the value of her stock. This is important for calculating profits, assessing how much insurance she needs, and controlling cash flow.
Wendy can use the sales data to show which items sell best and which are most profitable. She can also see how sales vary in the course of the year, and use this to plan for the future (for example, if she closes for an annual holiday it would pay her to do so during a quiet period).
