I think I may be missing something here.  Is the client actually releasing funds into an escrow account, to be held until the agreed upon payment date?  And, if so, who controls the escrow account(s)?  Is that how the client commits to payment?

If the client is required to release funds prior to downloading the search, then the money's gone.  So why not pay the abstractor right then and there?  Why wait until some future date?  Unless, that's how you would earn your profit, from interest on the account(s), in which case, I applaud your ingenuity.

I doubt, however, that it will ever get off the ground.  There are any number of reasons why the client does not pay the abstractor up front.  And I don't think adding an extra step for them to get their product is going to do much to induce them to turn their accounting systems upside down, as well as their order production and management systems - which often involve the abstractor typing the report directly into their system. 

I would not be the first to sign on to your program, because then I, and those who join me as your clients, are going to lose half of our customers right off the bat. 

And what about this?  If you control all that money destined for abstractors, what's to stop you from running off with it at some point?  Wouldn't be the first time an escrow account was raided.

Nice idea.  And good for you, thinking outside the box.  Unless I'm misunderstanding how it would work, which would not be the first time, it ain't gonna happen.
