I would need to look at the whole process, but if you have called to schedule a meeting, then your phone call sale was the meeting, which may or may not close at a higher rate and regardless, you have added an extra step, (phone call to schedule + Meeting + Close vs. Phone call + close).My point was just that phone calls are going to convert a hell of a lot lower.
My lead funnel is setup so that people that are not highly qualified buyers will filter themselves out, by the time I pick up the phone (or more likely they call me) they are foaming at the mouth to sign the deal (my deals are mid 5 figures typically). I may be leaving some deals on the table with this method, but I only have to get my hair cut 2-3 times a year, shave a couple times a week, and wear woot t-shirts most days.
