Simple Operating Agreement
Legal Contracts - Under state laws, only a few category of contracts must be in writing, such as a mortgage contract or contracts covering more than a year. It's still a good idea, however, to have a written agreement for business transactions beyond an ordinary sale of goods. There is no law requiring a lawyer to write your contract. If the transaction is relatively simple, the contract can also be simple. But you also have to pay attention to certain details to avoid issues arising later.
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.
