those contracting with the writer for work also benefit from a professional contract. contracts protect both sides of the agreement. a description of the work requires the one contracting with the writer to define what is expected of the writing project, including research and quality requirements. the agreement contracts the writer to keep the information that they know about the client’s proprietary business information private. this clause means that if one part of the contract is considered invalid, the rest of the contract is still valid. one contract that you’ll use often is a consultant agreement. it includes agreements about the scope of work and payment schedules.
