Average. Calls that ring but no one picks up, including after-hours.
What does a typical job invoice for?
Of the calls that DO get answered, what % become paying jobs?
Of new jobs, what % become repeat customers within a year?
A repeat customer is worth this many times the first job (e.g. 3 = $1,050 over time on a $350 first job).

How this calculation works
We multiply your weekly missed calls by your close rate to estimate jobs lost. Each lost job is then valued at your average ticket price, with a multiplier for repeat customers (the long tail of lifetime value most owners forget about). The default 30% repeat rate × 3x LTV multiplier comes from typical home-service industry benchmarks (HVAC, plumbing, cleaning). Your real numbers may be higher, especially for recurring services like pest control or maintenance.

Solo HVAC operator
1 truck, $450 avg ticket, misses ~12 calls/week between job sites.
Loses ~$165,000/year in missed revenue when you add repeat-customer LTV. Even a $300/mo AI receptionist pays for itself 45x over.
Cleaning company with 4 crews
Recurring weekly + biweekly clients, $180 avg, 7 missed calls/week.
$85K+/year in missed revenue because cleaning has long LTV (60% repeat rate, 8x multiplier). One booked repeat client pays for AI for the year.
Plumbing shop, 3 techs
Emergency + scheduled work, $385 avg, calls at all hours.
Most missed calls happen after-hours and on weekends, exactly when emergency tickets are highest-value. 24/7 coverage is where the ROI is.
