Home improvement sales run on activity now and revenue later. If you only score closed deals, reps go quiet during the long stretches. The fix is to gamify the leading activities too.
Score the leading indicators
Run contests on demos set, inspections booked, and follow-ups made, not just signed contracts. Those are the actions that produce next month's revenue.
Use teams across crews
Pit offices or crews against each other. A little rivalry between locations drives more effort than a company-wide average ever will.
Put it on the floor TV
Reps come and go between appointments. A big-screen board in the office means the standings are the first thing they see when they walk back in.
