Standard Rental Agreement Form
If you run a business as a sole proprietorship, it would be appropriate to be identified in the contract as John Jones doing business as Jones Plumbing. If you organized your business as a Limited Liability Company, identifying your participation in the contract by your name could remove any personal liability protection that an LLC provides. Similar issues can arise with a partnership if each individual is identified as a party to the contract.
Define the Scope of the Work - The terms constitute the body of the contract. Start off by clearly defining what it is the scope of the work or service you are to provide, and the timeline you propose to complete the work. Be specific. Don't simply say you will renovate a client's kitchen. Provide details of the cabinet designs, countertops, and other materials and work you will provide. If applicable, give a timeframe for each phase of a project.
