Three inputs — calls that walk into voicemail in a week, your average ticket, and the conversion rate you want to defend against. The 3-column result row shows the booked jobs your shop is losing per week, per month, per year at that rate.
The same per-call formula the audit reads off your real call log — walked against the numbers you punch in here.
Worked example
Edit any input — the row below computes week / month / year at that conversion rate, in the same line items the per-shop audit will defend.
A burst pipe on Cherokee after 11pm. A sewer back-up before a Sunday tenant move-in. A water-heater swap before an open house on Sunday at 1pm.
Burst pipes after 11pm, sewer back-ups before a Sunday, and water-heater swaps that walk to the next plumber before the dispatcher picks up.
Default $480 reflects the cross-trade mid-band the audit brief publishes — edit for your shop.
Lower for a one-dispatcher shop on a busy storm-front afternoon; higher for a two-line office with after-hours coverage. Stress-test at the rate you actually defend.

Numbers above track 40 missed calls/week × 30% × 4.33-week month and 52-week year constants. The audit pulls ten of your recent inbound calls and your last quarter's ticket values to fill the same inputs from real numbers.
Numbers are a worked illustration, not a guarantee. The audit fills the same inputs from your last quarter of calls and tickets.
Next step
A 20-minute audit pulls ten of your recent inbound calls and your last quarter's ticket values to fill the same inputs from real numbers — no install, no commitment. The figures above are the upper bound; the audit nails it down.
