Sign – Off forms

Hi guys,

I need to make a sign off form for a client, but I have no ideas as to the format for a professional sign off form for a completed software project.
So I have decided to place this as an outline to my content, could you guys have a look at this and
shed some light on what I should or subtract ?

1.Company logo and letterhead
2.A description of the project along with screen shots showing what the software programme does.
3.A form allowing the client to write about areas he/she was happy/not happy about and a blank line where the client signs to agree that the software program is satisfactory.
