Write or type up the date on the agreement to establish an effective date. List the parties involved in the agreement, using full business or individual names and titles. For example, you may title your business as the "Service Provider" and the customer as "Customer."
Describe your obligations, including the service you must perform to fulfill your obligations under the contract and be as detailed as possible. For example, if you are writing a marketing brochure for a customer, describe the length of the brochure, the purpose of the brochure and establish that you are only responsible for providing the text, and not the layout or design, for the brochure.
