AI receptionists by industry
What an AI receptionist actually has to handle in your industry — the calls that come in, what it must never say, and which vendors document the features that job needs.
Dental
$334.51 to $763.99 in gross billings per patient visit, the interquartile range for solo general practitioners (median $480.75, average $576.26; ADA Health Policy Institute 2025 Survey of Dental Practice, Table 9). A patient who stays with the practice is worth more than one visit: people with any dental visit averaged $887 in dental expenditures in 2021 (AHRQ MEPS), and the average income for GP dentists was $215,320 in 2025.
A dental phone rings hardest at exactly the times nobody can pick it up: 7 a.m. before the first patient is seated, over the lunch hour when the front desk is at lunch too, and after 5 p.m. when a crown comes off or a tooth cracks. The only person who normally answers is the one front-desk coordinator who is simultaneously checking in a patient, running an insurance eligibility check, and collecting a copay, so a second inbound call goes to voicemail by default. A missed call is not one lost cleaning, because a new patient calling around for a practice that takes their plan will book with whoever answers, and the practice loses the repeat hygiene visits and the restorative work that follow. The average new patient already waits 16 days for a first appointment with a general dentist, so a caller who does not get through simply dials the next practice on their insurance directory.
Electrical
$163 to $538 for a routine electrician service call (national average $351), rising to $518 to $2,192 for an electrical panel replacement (national average $1,346) and up to $4,500 for a full amperage upgrade
Electrical call volume splits into two streams that are handled very differently. One is safety escalation: a burning smell at an outlet, a buzzing or scorched panel, arcing, or a partial outage after a storm, and those arrive at any hour from a caller who will not wait on hold. The other is a planned-project pipeline (panel upgrades, EV charger circuits, standby generators, rewires) where the homeowner is calling three or four contractors and the first one to call back usually books the job. The person who would normally answer is a licensed electrician who is on a ladder, in a crawlspace, or has gloves on inside a live panel, which is exactly why the phone rings out during the working day.
HVAC
$130 to $2,000 for an HVAC repair (national average $350, on top of a $100 to $250 initial service call fee), rising to $5,000 to $12,500 for a full system replacement (national average $7,500)
HVAC demand is weather triggered, so it does not arrive as a steady trickle. The first hard freeze and the first sustained heat wave put a season's worth of no-heat and no-cool calls into about 48 hours, and a large share of them land overnight, on weekends, and before 7 a.m., because that is when a household notices the house is cold or the air handler is blowing warm. The people who would normally pick up are the same technicians the Bureau of Labor Statistics describes as on call for emergencies and working irregular schedules during peak heating and cooling seasons, which means that during a surge every one of them is in an attic, on a roof, or under a house with the phone in the truck. A missed no-heat call in January is usually not a lost $350 repair; it is a homeowner who dials the next company on the list, buys a $7,500 replacement system from them, and takes the maintenance agreement with them.
Law Firm
$135 to $461 per billable hour is the national spread of average lawyer hourly rates by practice area, from juvenile at the low end to corporate at the high end; the national average across all lawyers is $349 and the average blended rate a firm charges, counting non-lawyer time, is $311 (Clio, 2025 rate data). A state survey gives the same shape by field: the State Bar of Michigan 2026 Economics of Law Practice Survey puts the median at $350 with a 25th percentile of $275 and a 75th percentile of $465. No neutral body publishes a national average value for a single legal matter, so this range is deliberately one hour of billable work, the floor of what a retained matter is worth. A firm running an ROI number should substitute its own rate and the hours its typical matter actually takes.
Legal calls arrive at the worst moment in someone's life and almost never during a quiet hour: after an arrest, after a crash, the afternoon a process server hands over a complaint, the day a spouse moves out, the week before a filing deadline. The person best placed to answer is the lawyer, and the lawyer is in a deposition, in front of a judge, or in a meeting where picking up the phone is not an option, so the call lands on a paralegal who is also covering three other matters. A missed call is rarely recovered because the caller works down a list of firms until someone picks up, and the caller who reaches a human first usually signs. Intake also has a legal cost the other trades do not have: whatever the caller says is confidential from the first sentence, and if the firm captures enough detail before running a conflict check it can disqualify itself and every other lawyer in the firm from the matter.
Medical Practice
$105 to $214 allowed per new-patient office visit under Medicare, using 2024 national averages: 99203 $105.33, 99204 $160.28, 99205 $213.67. Average submitted charges for the same three codes were $267.25, $410.82 and $560.92. Routine follow-up allows less: 99213 $85.37 and 99214 $119.71. Commercial contracts normally pay above the Medicare allowed amount and any procedure, imaging or lab billed at the same encounter adds to it, so a practice should substitute its own contracted rate before running an ROI number.
Almost every call to a medical practice contains protected health information from the first sentence, which makes the phone a compliance surface as much as a revenue channel. Volume is front-loaded and unforgiving: Monday mornings, the hour after a practice reopens, and the hour after each specialist's clinic ends, all landing on a front desk that is also rooming patients, chasing prior authorizations, and working a fax queue. The person who normally answers is a medical assistant or receptionist with no clinical authority, so a caller describing chest pain, a post-operative fever or a suicidal thought is being triaged by whoever happened to pick up. A missed call is worse than a lost booking, because the caller either goes to an urgent care or an emergency department or waits, and with the average new-patient wait already at 31 days across six specialties in 15 large metro areas, they have every reason to try a different practice instead.
Plumbing
$182 to $500 for a typical plumber visit (national average $340, with a $100 to $250 service call fee that usually covers the first hour, plus $100 to $300 or more outside regular hours), rising to $881 to $1,826 for a water heater replacement (national average $1,346)
Plumbing is the trade where the caller is usually watching the damage spread while the phone rings. A burst supply line, a failed water heater or a sewage backup gets measurably worse every minute, so the value of the call decays by the minute in a way a scheduled fixture install never does. The Bureau of Labor Statistics describes plumbers as often on call to handle emergencies with night and weekend work common, which in a small shop means the owner is the after-hours answering service and is asleep, driving, or already under someone else's sink. The number at stake is not the $340 service call: insurers put the average water damage and freezing claim at $13,954, and the contractor who picks up first is the one who gets to stop the loss, then quote the repipe and the restoration referral that follow it.
Roofing
$395 to $1,966 for a roof repair (national average $1,173), rising to $5,902 to $13,373 for a full roof replacement (national average $9,607)
Roofing demand is not a trickle, it is a switch. NOAA's Storm Prediction Center logged 5,432 hail events of one inch or larger in 2025, and 902 of them were in Texas alone, so a single afternoon of hail can drop a market's whole quarter of calls into the following 48 hours. Nobody staffs a phone room for that: in most shops the owner and one or two estimators are already up on ladders running free inspections when the surge hits, and the overflow rings out while out-of-state storm crews knock the same streets. Wind and hail is the most common homeowners claim there is, averaging $13,511 per claim, which makes every unanswered call in a storm week a five-figure job that goes to whoever answered.
Salon and Spa
$35 to $150 for a haircut and $151 to $319 for color or highlights (midpoint $219) on Thumbtack's national cost estimates, with balayage at $167 to $358. On the spa side the industry-wide average is $123.10 of revenue per visit in 2025, up 2.3 percent year over year (ISPA and PwC, 2026 U.S. Spa Industry Study). A retained client is worth several of these a year: US consumer units spent an average of $978 on personal care products and services in 2024 (BLS Consumer Expenditure Survey).
In a salon the person who would answer the phone has both hands in someone's hair, and in a small spa the therapist is inside a treatment room where a ringing phone is the one thing the client is paying not to hear. Calls come in exactly when the floor is busiest: Thursday and Friday afternoons, Saturday mornings, and the evening hours after clients finish work, which is also when a stylist working behind the chair cannot stop. The loss is doubled, because a missed call is usually both a booking that goes to the salon down the street and a chair that sits empty at that hour with the stylist still on the clock. Bookings are also personal rather than generic: a client wants their stylist, not any stylist, so a message taken without checking that specific column tends to become a cancellation rather than an appointment.
