AI Voice Agent / 24/7 Call Answering
How much revenue am I losing from missed calls?
Missed-call revenue loss equals missed calls per week multiplied by the percentage that are real buyers, multiplied by your close rate, multiplied by your average job value. A contractor missing 15 calls per week, with 40% being real buyers, a 30% close rate, and a $7,000 average job, loses $12,600 per week — $655,200 per year — to unanswered calls. Most contractors underestimate this number significantly.

How to calculate your missed-call revenue loss
How to calculate your missed-call revenue loss
Pull your call log for the past 30 days. Count calls answered versus missed (including voicemails not returned within 2 hours and after-hours calls). Estimate what percentage of those missed calls were from real buyers — homeowners with an active project, not solicitations or wrong numbers. Apply your typical close rate and average job value. The result is your monthly missed-call revenue leak.
Why after-hours calls matter most
After-hours calls — evenings, weekends, and storm-event surges — are typically higher-intent than daytime calls. A homeowner calling at 9pm about storm damage is motivated by urgency; they will call three to four contractors and hire whoever calls back first. Missing an after-hours high-intent call is not just a missed call — it is a missed job that will close with a competitor within hours.
What this compares to in other costs
Contractors spend $3,000–$15,000 per month on advertising to generate inbound calls. Missing 30% of those calls means 30% of the ad spend produced zero return. Fixing the call-answering gap recovers revenue from advertising already paid for — without additional ad spend. It is the highest-ROI fix available to most contractors because it converts existing, paid-for demand.
What is realistic for a $5M roofing company?
A $5M roofing company receiving 120 inbound calls per month and missing 25% — 30 calls — with 35% being real buyers, 28% close rate, and $9,000 average job: 30 × 0.35 × 0.28 × $9,000 = $26,460 lost per month. $317,520 per year. Recovering half of that through 24/7 AI answering — $158,760 — against an $800 per month system cost ($9,600 per year) produces a 16.5× annual ROI.
Common questions
How do I know how many calls I am missing?
Most phone systems log missed calls. Check your phone log for calls that went to voicemail, calls outside business hours, and calls during your busiest periods when the line was engaged. If you use a cloud phone system (RingCentral, Google Voice, CallRail), the missed-call report is typically under Analytics or Call History. The number is almost always higher than business owners expect.
Does missed-call revenue loss apply to weekend and evening calls?
Especially so. In service industries, a disproportionate share of high-intent calls arrive outside business hours — homeowners discovering a problem in the evening or weekend and calling immediately. These calls have the highest intent and the highest likelihood of being missed, making the after-hours window the largest single source of missed-call revenue loss for most contractors.
What is the fastest way to stop missing calls?
Missed-call text-back — an automated SMS to every unanswered call — goes live in 24–48 hours and is the fastest single fix for missed-call revenue loss. The SMS asks the caller what they need and routes real buyers back into the queue. Full AI call answering, which answers live and qualifies, takes 48–72 hours to configure and goes deeper.
