I am an independent mechanical design and engineering consultant. I develop many products for entrepreneurs with the next "million" dollar idea. It seems that I can never do enough to ensure payment fromthese customers. No matter how attentiveI amto my customers' needs, and no matter how awesome the design and prototypes function, all-to-often it seems that they still want to "stiff" me. When the job is complete, they try to negotiate price. Even after I get 50% down, they risk losing their inital 50% and stilltry to negotiate price (my terms are 50% down and payment of balance upon completion of work). When I ask fora bank check, they become offended. And the story goes on and on...
HOW CAN I CREATE EXPIRATION DATES ON PRO|E FILES?????? This is the big question?What if they pay me and then cancel the check (this has never happened to me, but it is only a matter of time)? How can I make it so that they have to come begging back? LOL!!!
Passwords are okay, but still not fullproof enough. If I could set a1 weekexpiration date on files untilthe customers'payments clear, then that would be great. Furthermore, I either need to restrict the ability to copy the files, or clone the expiration dates and/or passwords with any copies of those files.
By the way, this is not a huge problem; however, it is bothersome enough to inquire about the possiblities and options. I don't want to have to take customers to small claims court. This is a complete waste of time. Judgements against my customers are easy, but collections are still nearly impossible.
I never have these problems with corporate customers. I come from corporate America, and my corporate customers are very professional in the way they process my quotes, purchase orders, etc.

In Wildfire 4.0, PTC has added an optional Rights Management module that allows you to do exactly what you are asking to do. It allows you to give variable levels of permissions (Open, Print, Save, Copy) to named individuals, and to expire those permissions anytime you'd like. If your customer won't pay you, you can turn off his access to your work.
