What document is essential for a contractor engaging in a project?

A written contract is essential for a contractor engaging in a project because it serves as a formal agreement between the contractor and the client. This document outlines the scope of work, responsibilities, timelines, payment terms, and any other specific conditions that govern the project. Having a written contract helps protect both parties by providing clear expectations and legally binding terms, reducing the likelihood of misunderstandings or disputes.

In contrast, a verbal agreement lacks the formality and legal enforceability of a written contract, making it difficult to prove the terms if disagreements arise. A warranty deed pertains to the legal transfer of property ownership rather than the specifics of a construction project, and while a business card may be useful for networking, it does not carry any contractual obligations or details about the work to be performed. Therefore, the written contract is crucial for documenting the agreement and ensuring that all parties are on the same page throughout the course of the project.
