A site for service pros to rate a customer?

No offense - I think this would be a waste of time and resources. Sure there would be exceptions but generally this would just turn in to just a place to complain about bad customers and probably not talking about good people. Customers aren't going to give two thoughts about changing their behavior because we all got together and tried to rate them. This tool would need to be adopted on such a wide spread level for it to be useful, and I feel like the juice would not be worth the squeeze. You probably need millions just to dump in to development, then in to marketing for this to be somewhat useable.

I may be wrong, but it sounds like we are looking for a way to better vet customers. In my opinion, the best way to do this is with a solid discovery call where you spend a few minutes getting to know them and what their problem is instead of a canned phone call where you are looking for an opportunity to plug your services. You're a pest control company so that's lower tickets, so I'd imagine the onboarding timeline is probably faster than my business. That being said, I still think we need to take a deep breathe and listen to what these people are saying, build better processes, build better contracts, and always take a credit card on file.
