Labor and material costs are also directly proportionate to sales. These are things that go directly into the making of the product or into doing the service. a. Labor cost is the actual direct labor used in the making of product or doing the service. The cost would also include all the fringe benefits like social security, payroll taxes, vacation pay, holidays, sick pay days, etc. b. Material costs are all the materials used in the making of product or in doing the service. In the lawn mower service as an example it would be the gasoline used in the mower and any other materials used directly in that service. For producing a product it would be all the materials used in the product that is sent to the customer including all the packaging materials.
I mentioned that the 'writing of a business plan' as one of the pivotal steps involved in setting up a successful business. By now you should understand the need for writing a business plan. Writing a business plan, for a traditional brick and mortar business, will probably take a lot of time. It may take up to 100 hours or even more. For obvious reasons, a new business needs to carry out a lot of research before a business plan can even be developed.
