Canceled Calls

New Contributor

I run a 25 tech plumbing company. We have anywhere from 900-1200 calls per month with a 92% booking rate.  I would like to know what is  the average canceled calls % to booked calls regardless of reasons. Also what to you is an acceptable reason and what is not? I get that some calls are booked incorrectly or duplicate calls. Problem fixed itself is a big one in the drain business. 

My point is how can we get a simple metric that we can live with. Thanks for your input.
