CUSTOMERS WANT IT!
A recent survey of the buying public found that 91% would rather buy a service that had an upfront price (or flat rate) than have service performed on a time and material basis. Since we are in the service business it should be very important to deliver what the customer wants.
In our busy society time is important, and consumers do not want to spend their time watching the clock on a service technician making a repair. Consumers do not like open ended repair bills, but prefer overwhelmingly to know the total price up front with no hidden surprises. This menu pricing as it is sometimes called is used in many businesses today and if you look you will find flat rate everywhere.
Doctors flat rate office visits, lawyers flat rate divorce and bankruptcies, home services such as pest control, lawn service, and others are flat rate, automotive repair has been flat rated by major manufacturers for over 60 years, dentists, restaurants, and a host of other services are provided by a fixed price delivered before the service is performed.
If customers are more comfortable with flat rate pricing it makes good business sense to give them a pricing method they will accept with less anxiety.
