Pick your trade, set how many calls you miss in a normal week, and see what those calls are worth in booked work. Built on ServiceTitan, Invoca and CallRail data — the conservative end of it.
Count after-hours, lunch, on-a-roof, already-on-another-line. Most 1–3 truck shops land between 4 and 10.
Pre-filled with the service/repair average for your trade — deliberately low. Swap in your own number for a real answer.
A missed call isn't worth a whole job. This model discounts it three times before counting a dollar:
| Step | Value |
|---|---|
| Missed calls that are real leads (not spam, vendors, wrong numbers) | 55% |
| Calls that book if someone answers (ServiceTitan: 42%, Invoca: 46%) | 40% |
| Callers who never come back to you (CallRail: 82% call a competitor) | 50% |
| Net value per missed call | 11% of a ticket |
So a missed call is only counted at $33 here, not the full $300. Monthly uses 4.33 weeks.
Sources: ServiceTitan booking-rate study (3,000+ trade businesses, 42% average — 24% for shops under 5 techs). Invoca 2025 Call Conversion Report (60M calls, home services convert phone leads at 46%). CallRail (1.1M leads: 14% of calls missed during business hours; consumer survey n=1,000: 78% have walked away from a business after an unanswered call, 82% call a competitor).
What's deliberately left out: lifetime value. One booked HVAC customer is worth $15,000+ over the relationship, not one ticket. Every number above ignores that.
Calypso AI builds an AI call agent for your shop that picks up 24/7, qualifies the caller, gives a ballpark range, books the job into your calendar, and texts anyone it couldn't close. First 60 days free — you only pay if it's booking you work.
