I was going through looking for comment on charging for estimates and came across this.
There is a tremendous variability for us about volume of calls. Some weeks 100 calls, this week 2. That is quite the range...
As far as how many estimates in a week during the busy season, 40 is quite a few and probably average.
The qualifying and pre-interview for me is critical. I know what we sell and if you aren't looking for us, you will be wasting my time. I give the price for anything that is remotely small over the phone - having well established minimums. I am not retentive about this, but I stick by my guns unless there are extenuating circumstances.
Driving is a waste of time. Line them up well. Confirm them. Show up on time or call. Use email if your client uses it. Communicate clearly (about 30% of people cannot be communicated with effectively no matter how clear you are) Appointments have a MUCH higher probability of closure. I have had secretaries schedule days with high amounts of backtracking.
The reason I went looking is exactly what you stated - each estimate takes an hour. 200 estimates X $75 = $15000. Estimating cost for a month. Why exactly do we not charge for estimates? Incidentally, saying there is a charge on the phone tells you whether the potential client is cheap or not. My experience is that they never even ask you how much is the charge. I charge $11 for an estimate to be refunded on the work performed invoice for an "estimate". If you are going to ask me any questions or you aren't sure what to do and need my "professional opinion" the cost is $47 and I am not going to deduct it from the work invoice. I do spend quite a bit of my down time learning as much as I can, so my opinion has some validity - maybe not congruous to everybody else, but my perspective.
