When I was a CI I basically did glorified hang and bangs. TV installs/SONOS/Home Theaters..
I sold maintenance contracts all day every day.
How/Why can you sell a maintenance contracts for a TV mount? Twice a year come out, take the TV off the wall, air-blow the dust bunnies off the back of the TV, maybe change any programming in the remote that might be needed, make sure IR flashers (in the day) were snug still, clean the screen... done..
We all know that the majority of our customers have housekeepers...But the house keepers can't/don't/won't clean the AV equipment..
Interesting - what was your pricing/tier structure or was it a one size fits all.
