I have had a potential chiropractic client ask for a tier percentage plan. Basically start charging him 8% and then in 6 months if his receiveables have increased by "x" then his percentage would decrease by "y". I have never worked with this before and I am not sure what the variables should be. I was thinking like if the average monthly was 5k and in 6 months his has increased to 10K reducing the percentage to 7.5%. Does that sound fair? I apperciate any and all input.Thanks!Cara
