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.
Describe the payment terms for the transaction, including the total amount for the service, how much and when the deposit is due and how much and when the final payment is due. Spell out a time line or milestones. Include specific dates for the delivery of parts of the service or the final deadline for the service to be complete.
