Classes can represent many different things – departments, regions, individuals, lines of business, service types, or locations. Tracking performance by class can give you valuable insight into your company, showing you where you need to make tweaks or even radical changes.
To determine your classes, look at how your business runs (or where you will be making future expansion). What is the most important way to track your business? Do you have sites throughout the region – then creating a Class for each site might work best for you. Are you a sales or service business and want to track by sales person or service provider? Are you sole proprietor who is providing different services and want to see which gives you the best income or profit potential? Any of these needs can be tracked by using Classes.
