Marketing is the cost of marketing to your Customers, and includes postage, printing, list services, and other advertising expenses. It is an indirect sales cost, and does not vary directly with sales revenue. However, it does vary with the number of Customers marketed to. We calculate Marketing as a fixed dollar amount per Customer. Note that since Marketing is related directly to Customers, marketing expenses related to Leads and Prospects are calculated as a part of Overhead rather than as a part of Marketing. The default value for Marketing is $1.00 per Customer. When entering your own value, do not include the dollar sign ($).
