A contract between two parties for services is a written agreement that outlines two or more parties’ expectations with regards to a particular service provided. This contract may cover such areas as quality and quantity of the service required, payment terms, deadlines, responsibilities of both parties, and any other necessary terms or conditions. In essence, it’s a way for businesses to ensure that everyone involved in a transaction is clear on what is expected so that all parties involved are able to deliver the best possible outcome.
