Running the numbers
Start with average job value by trade. HVAC repair averages $350 to $600 per service call. Plumbing ranges from $200 to $800 depending on complexity. Roofing replacements average $8,000 to $15,000 but the first contact is still a call. Electrical service calls run $250 to $500. Even at the low end, these are not trivial transactions.
Close rate on inbound calls from people who actually reached you runs 30 to 50 percent for most service trades. That means if you miss the call entirely, you lose 100 percent of a lead that was already halfway to becoming a customer. They were calling because they had a problem and they needed help. The only thing that stopped the conversion was you not answering.
Do the math: 8 missed calls per week at a 40 percent close rate and a $400 average ticket is $128 per call in expected revenue loss, or $1,024 per week, or $53,248 per year. For a plumbing company with higher tickets, that figure doubles. For a roofing company where one missed call might be a $12,000 job, even a single missed lead per week represents $240,000 in annual pipeline loss.
The compounding effects that do not show up in the math
The direct revenue loss is only part of the picture. Missed calls also affect your review velocity. A customer who could not reach you and booked a competitor leaves zero reviews for you and possibly a negative one. Over time, that drags your local search ranking, which reduces inbound volume, which means even more missed calls.
There is also a referral effect. Service businesses live on word of mouth. The customer whose emergency you handled well at 8 PM on a Saturday refers you to three neighbors. The one who called and got voicemail tells their neighborhood Facebook group to avoid you. These are not hypothetical scenarios — they are the normal operating reality for any trade that handles emergencies.
Customer lifetime value magnifies everything. In HVAC, a homeowner who books a repair may also book seasonal maintenance, eventually a full replacement, and stay with you for 10 to 20 years. That first missed call could represent $8,000 to $25,000 in lifetime value, not just one $400 ticket.
What the fix actually costs compared to the problem
AI phone coverage that eliminates missed calls runs $150 to $300 per month depending on the platform and feature set. At 8 missed calls per week recovered at typical close and ticket rates, the payback period is measured in days, not months. Even if you only recover 30 percent of what you were missing, the economics are strongly positive.
The more relevant comparison is what you are already paying for marketing. Most service businesses spend $500 to $2,000 per month on Google ads, SEO, or lead generation services. All of that spend is undermined if calls generated by those campaigns go unanswered. Fixing the front office before adding more top-of-funnel spend is the highest-ROI move most service operators can make.
Track your missed call rate for one week. Count the calls that went to voicemail and were not returned the same day. Multiply by your average ticket and close rate. That number is the cost of the status quo. The fix is a fraction of it.
