Door hangers
You leave hundreds of door hangers, and the calls come in while you're in the middle of another water test. You can't answer, and that lead is gone.
Krone: An AI receptionist answers every door-hanger call and books the appointment on your calendar.
The in-home demo
You run the test with strips and notes on paper. You leave, and the customer has nothing to show their spouse except "I'll think about it."
Krone: A guided water test on your tablet, with photos, signatures and a diagnostic PDF the customer keeps.
The follow-up
The "I'll think about it" customers go cold, and nobody calls them back.
Krone: A 7-touch follow-up plan, with the AI voice agent calling back for you.
The leads
You pay for ads and get plenty of leads, but many aren't ready to buy, and the good ones wait too long for an answer.
Krone: The WhatsApp bot answers right away, qualifies each lead and books the ones ready to buy.
The territory
You don't know which streets you've already covered, so you knock the same doors twice and miss others.
Krone: Every door on the map, with territories and optimized routes.
Referrals
Your happy customers would refer their neighbors, but there's no system, and referrals get lost in notes.
Krone: A built-in referral program with points and payouts, so every customer brings the next one.
