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."
Establish ownership rights to the work. Even in service situations, a product is sometimes the result of the work, so you should also include which party retains ownership rights. For example, the copywriter can state that she turns over all rights to the writing of the brochure to the customer and that she makes no claims of ownership to the writing once the customer pays for the written product. Add signature and date lines. Be sure to provide a space for each party to sign and date.
