What does marketing involve?  

Marketing is your most important organizing tool. There are four basic aspects of marketing, often called the four Ps: 

·         Product: The item or service you sell.  

·         Price: The amount you charge for your product or service.  

·         Promote: The ways you inform your market as to who, what, and where you are.  

·         Provide: The channels you use to take the product to the customer.  

As you can see, marketing encompasses much more than just advertising or selling. For example, a major part of marketing involves researching your customers: What do they want? What can they afford? What do they think? Your understanding and application of the answers to such questions play a major role in the success or failure of your business.

This is the general market potential. Knowing the number and strength of your competitors (and then estimating the share of business you will take from them) will give you the market potential specific to your enterprise.
