Are you old enough to remember when the only thing you expected your Techs to do was show up to a customer’s house, do only the work requested, and then let you know what that was so you could send the customer a bill in the mail at the end of the month?
Ah, the bad old days…
Why bad? Because the customer doesn’t know the systems in their home the way your Techs do.
The good news is Tech’s don’t really have to “sell,” at least not in the stereotypical way. All they really need to do is communicate what they know and practice ethical selling principles. If they do that, the sales will follow naturally and will be a win for the customer first, a win for the company second, and thirdly a win for the Tech.
