Variable expenses are those expenses that track directly with sales. If sales stop they stop. These are expenses like supplies used to support in the making of your product or doing your service. Such things as shipping cost for raw materials for your product or service. If you have no sales then you're not going to be purchasing materials so your shipping cost for those materials will stop as well. As an example, if you have a lawn mowing business and there are no lawns to mow, then you wouldn't be buying gasoline to travel to your lawn mowing site. These kinds of things are variable expenses. If you're producing a product, it would include supplies used to produce that product like sand paper, glue, finishing materials, cutting tools, etc.
Creating a Marketing Plan _ Similar to a business plan, the marketing plan spells out how you will market to new customers and retain current ones. The marketing plan should identify your target customers and develop a strategy to reach them effectively. Your marketing plan usually includes market research that gives you a profile of the ideal customer. As with your other plan, it is important to identify any strengths, weaknesses, opportunities and threats that may affect your company's operations.
