Write a termination clause that explains the steps that one or both parties need to take in order to terminate the contract. For example, you may say that either party can terminate the agreement with a written 15-day prior notice to the other party. Also, include payment terms for any work completed to date that the customer is responsible for paying for this portion of the work. Write a dispute clause to establish the handling of a dispute between the two parties. For example, arbitration is one method the parties can agree to in the case where a dispute arises between them.
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.
