You could definitely do that, but really, nobody here should recommend that. Depending on the country being deployed you could put the client in (potentially serious - Singapore - seriouslly?!?!) legal risk. We thought about it too, but ultimately decided that was not a good solution and that we should just wait for the rev and explain it to the client. I'm not sure of your line of business, but in the consulting world that could have terrible consequences for the firm and the client.
MeMeMeMe - think long and hard about doing that before making that decision and make sure that upper level management is in the know if you choose to go that way. I would NOT recommend it.
