While you may have to spend money to make money, you don't have to spend it for Flat Rate Plus at Easy Street, Inc. (Mr. HVAC). Their roots are in HVAC, and it doesn't translate well. If you've ever seen a tin-bender wire an air conditioner, you know what I mean.
I'm going to start a new thread on creating your own sales book for a flat-rate system in the hopes that you don't go through the disappointment I did with Flat Rate Plus at Mr. HVAC.
BTW, the gentleman that runs Mr. HVAC and Easy Street, Inc. is a top quality businessman. He has wonderful ideas on the video that came with Flat Rate Plus. These same ideas are at pmmag.co , a magazine for plumbers with many articles on using a flat-rate system.
Things like...have a nice uniform, clean truck, look people in the eye, act professional, be on time, keep your promises, warranty your work, return your calls, be available, etc. Good business translates to any business.
As far as price goes, do you want to be a package of freeze-dried coffee at the supermarket, or a $2 cup at the mall. People buy both willingly. Of course a $2 cup better come with clean shoes and a smile.
Set your rates wherever they need to be for your business to be profitable. The typical fear that your customers will abandon you if you raise your rates...typically don't happen at all.
