Key Takeaways
- A full-time receptionist costs a small trades company roughly $40,000 to $46,000 a year in the worked example below, and covers only about a quarter of the hours in a week.
- A part-time hire at 20 hours a week costs about $23,000 a year in the same example and covers about 12% of the week.
- An AI receptionist is usually a flat monthly fee. At a hypothetical $300 a month, that is $3,600 a year with coverage on nights, weekends, and every overflow call.
- A human is still better for complex customers and in-person front-desk work. Many small trades companies get the best result by letting AI take the first call and keeping a person for escalations.
- Missed calls are the real cost driver. Research on lead response shows speed decides who wins the job.
What is an AI receptionist, and how is it different from hiring one?
An AI receptionist is software that answers inbound calls, texts, and messages for a business, collects the caller's details, books appointments, and routes urgent requests to a person. It runs around the clock and handles many conversations at once. A hired receptionist is one employee who works set hours and handles one conversation at a time.
For an HVAC, plumbing, or electrical company, the difference shows up in three places: what you pay, when the phone gets answered, and what happens when two customers call at once. The rest of this post puts numbers on each.
How much does a part-time or full-time receptionist cost a trades company?
A part-time receptionist at 20 hours a week costs about $23,000 a year in the example below, and a full-time one costs about $46,000. Wages are only part of the bill. Payroll tax, paid time off, workers' compensation, and equipment all add to the total.
Here is a worked example. The $18 an hour wage and the 15% overhead figure are assumptions for illustration, so swap in your own local rate. The BLS Occupational Outlook Handbook publishes median pay for receptionists if you want a benchmark.
| Cost line | Part-time (20 hrs/week) | Full-time (40 hrs/week) |
|---|---|---|
| Wages at $18/hour | $18,720 | $37,440 |
| Employer payroll tax at 7.65% | $1,432 | $2,864 |
| Other overhead at an assumed 15% of wages | $2,808 | $5,616 |
| Estimated yearly total | about $22,960 | about $45,900 |
The 7.65% figure is the employer share of Social Security and Medicare tax, as described on the IRS Topic 751 page. Benefits and insurance vary by state and employer, and the BLS Employer Costs for Employee Compensation release shows that benefits are a meaningful share of total compensation. Hiring and training time come on top of those figures.
How much does an AI receptionist cost?
An AI receptionist is typically priced as a flat monthly subscription, sometimes with a usage allowance for call minutes. Say a plan costs $300 a month. That is $3,600 a year, or roughly 8% of the full-time example above. Actual prices vary by vendor and volume, so treat $300 as a placeholder for your own quote.
Costs to check before you sign up:
- Whether call minutes, texts, and extra phone numbers are included or billed separately.
- Setup or onboarding fees.
- Whether the plan covers text and email follow-up or only voice.
- Whether it connects to your calendar or job management software for booking.
, for example, pairs an AI voice agent with missed call text back and two way texting, so a caller who hangs up still gets a reply. Compare that kind of bundle against any hire, because the hire also has to cover texts and web inquiries.
How many hours of the week does each option actually cover?
A full-time receptionist covers about 24% of the 168 hours in a week, and a 20-hour part-timer covers about 12%. An AI receptionist covers all 168. The gap matters for trades because emergency calls tend to arrive in the evening, on weekends, and during extreme weather.
| Option | Hours covered per week | Share of the week | Handles two calls at once? |
|---|---|---|---|
| Part-time receptionist (20 hrs) | 20 | about 12% | No |
| Full-time receptionist (40 hrs) | 40 | about 24% | No |
| AI receptionist | 168 | 100% | Yes |
Vacation, sick days, and lunch breaks lower the human numbers further. To reach full coverage with people, you would need several staff or an after hours cover service on top.
What does a missed call cost an HVAC or trades business?
Each unanswered call risks a lost job, and slow replies lose jobs even when the customer leaves a voicemail. A 2011 Harvard Business Review study of online sales leads, available on ResearchGate, found that firms contacting a lead within an hour were nearly seven times as likely to qualify it as firms that waited even one hour longer. Lead response time is the variable that decides who gets the work.
Here is an illustrative calculation, not real data. Say your crew is on roofs and in crawl spaces and you miss 8 calls a week. If half are real jobs, that is 4 opportunities. If you would have closed half of them at an average ticket of $350, that is 2 jobs, or $700 a week, or $36,400 a year in lost revenue.
In that example, the lost revenue is larger than the cost of the part-time hire (about $22,960) and close to the full-time hire (about $45,900), and it is many times the $3,600 AI plan. It also shows why the cheapest option is not the one with the lowest payroll line. It is the one that stops the phone from ringing out. InstantReply.ai's missed call text back is built for that gap: a caller who hangs up still gets a text reply while your crew is on the job.
When is a human receptionist still the better choice?
A human receptionist is the better choice when your business needs in-person greeting, complex judgment calls, or emotionally sensitive conversations. An AI receptionist handles repeatable intake well, but it is not a good fit for every situation a front desk faces.
A person is worth the cost when:
- You run a showroom or shop where walk-in customers need a greeting.
- Your callers are mostly existing commercial accounts who expect a named contact.
- Dispatch is complicated and needs real-time negotiation with technicians.
- You handle billing disputes or warranty arguments that need empathy and discretion.
Many small companies use both. The AI answers first, books routine service calls, and sends emergencies straight to an on-call tech. A part-time person then handles the exceptions and the paperwork.
How does an AI receptionist compare with a traditional answering service?
A traditional answering service uses live human agents who take messages or follow a script for a per-minute or per-call fee. It costs less than a hire but usually does not book directly into your calendar or send follow-up texts. An AI receptionist can do both, and often costs less per month for a busy line.
Established providers include Ruby and Smith.ai. Both offer live-agent options and publish their plans, which is a fair benchmark for what a human-assisted service costs. Live agents can be a good fit if you want a person on every call and your volume is modest. Check each vendor's current pricing, since plans and minute bundles change.
How should a small trades business decide?
Start with the number of calls you miss and the value of each job, then compare that to the yearly cost of each option. If missed calls cost you more than the AI plan, start with the AI. Add a human only for work that software cannot do.
- Count missed calls and unanswered texts for two weeks, including after hours.
- Multiply likely jobs by your average ticket to estimate lost revenue.
- Price a part-time hire, a full-time hire, and an AI plan using your own wage and quote.
- Test an AI receptionist such as InstantReply.ai on after hours and overflow calls first, then expand.
- Review booked appointments, no show recovery, and customer feedback after 30 days.
Adding appointment reminders and quote follow up to the same setup also protects revenue you have already earned. A reminder text costs almost nothing compared with an empty slot on the schedule.
