Management of Order

Hello,

For my usage of Project'Or RIA, one important model/object is missing : Order

Most of project start with a customer that send to us an ORDER. with define the perimeters (or type of project, eg: fixe price, ...), the validate man/day, and an amount of money.
That's for me the start. And this is not manage in projector RIA.
If you decide to manage it, it can be solve some problem like :
- how fix the validate work in a project ==> it's simple; it's the sum of charges of all order link to the project.!
- how to calculate a maging ! ==> you have calculated cost on project, and orders of project give the sell price.
- you can give more coherence to terms, by attaching terms to an order.


What do you think about this notion ? have you already think about it and decide for some reason to exclude it for you solution ?

Thanks for you answer.
Best regards,

I already develop this order model, if you want i can give you my code (for information ?)
