The clawback language is the whole ballgame and I'd bet it was buried in the indemnification clause not the referral section, which is why people miss it. I've had staging vendors try similar moves on me in maricopa county and the answer was always the same: I stopped signing anything that tied my fee to final sale price and started tying it to close of escrow, full stop. If the deal closes, I get paid, period, arv is somebody else's problem. The 2,800 out of pocket for staging on a 281k sale is actually not the injury here, that margin math was broken before you ever called the stager. Next time pull the net sheet before you refer anyone and make sure your fee is a flat dollar amount triggered by recordation, not contingent on seller proceeds hitting a number.
