First, stop all work, close repos, etc etc etc. This doesn't help you now, but next time get a deposit of two-months estimated work up front. If they don't want to pay the deposit, don't work with them. Now, if you do two months of work and they happen to not pay you, you stop all work, take the deposit, and you lost nothing. If they want to start work again, charge another 2 month deposit up front and scold them for wasting your time. Time to scold you (sorry)...why the hell did you do 9 months of work without getting paid? What are you thinking?! You have inadvertently taught this company to never pay you, ever. You are now (and most likely always will be) the guys they get free work from. You might have to cut your losses and move on.
