30).Create a Project Agreement

Before starting any project, you must get into the habit of drawing up a project agreement. A project agreement outlines the exact project requirements, your completion schedule and terms pf payment. Most important, though, this will legally bind you and your employer to a project and will be of use in case a dispute arises with your employer. There are three parts to a project agreement:
Buyer/Provider Agreement
This part is a contract that outlines the basic project requirements, terms of payment and project milestones. A project milestone is a date (or multiple dates) of completion of each stage of a project. For instance, if you obtain a project to ghost write an autobiography,you may want to set a completion date of eight months. Then a milestone of 25% completion could be set for every two months after you start. You also set the payment requirement upon completion of each milestone, too. 
Statement of Work
Here, you get down to the nitty gritty and detail the project exactly. This is where you document all requirements the employer has and your methods of completing each one. I cannot stress enough that you take your time to understand every last detail of a project then make note of each one in the statement of work.
The statement of work is not necessary for shorter, simpler projects where all details can be mentioned in the buyer/provider agreement.
Most freelance work exchanges (FWEs) have a tool for you to upload a project agreement which must be agreed upon (online) by the employer before the start of a project. If not, you will have to make sure the employer signs and emails/faxes you the entire agreement. Either way, make sure you have this so you don’t get burned!
Change Order
This will not be a part of the initial project agreement between you and your employer but is necessary if any part of a project requires a change from the original agreement. The change(s) necessary are detailed including any additional costs. Most projects will require some change or another due to things that were forgotten by the employer or a change of taste. The change order ensures the change is fair for both parties.
