Check out this live sale I had while out doing my morning route of cleanings. A family drove by and inquired about the service and instead of just giving them a card/flyer and asking them to call me back when they have a chance, I stayed confident, pitched them, and closed them. I was fortunate to get a monthly sale out of it.
Make sure your technicians have the basics down! It's the small things like having your pricing sheet as your lock screen, building social proof with the neighbors, adding value, and hard closing when they've asked enough buying questions that really make the difference.
