Hire a part-time receptionist or automate the phone

Sooner or later every small shop hits the same week. The phone rings while you’re on a ladder, your best tech is elbow deep in a condenser, and your spouse has already said they’re done answering the business line at dinner. So you start asking around. Somebody’s cousin needs part-time work. A vendor in your inbox says AI can do it for a fraction of the price. Both sound reasonable. Neither one is free, and they solve different problems. This post puts real numbers on the person, says plainly what automation does and doesn’t do, and gives you a way to choose that doesn’t depend on whoever pitched you last.

01What a part-time receptionist really costs

Start with the wage, because it’s the number people get wrong in their head.

According to the US Bureau of Labor Statistics, receptionists earned a median of $18.27 an hour, or $38,010 a year, in May 2025. That’s the middle of the market. Some areas pay less, and a lot of metro areas pay more.

Now do the part-time math. Twenty hours a week at $18.27 is $365.40 a week. Over 52 weeks that’s about $19,000 a year, or roughly $1,580 a month. A full-time person at the median works out to about $3,170 a month.

That’s wages only. It doesn’t include the employer side of payroll taxes, workers’ comp, any paid time off, the hours you spend training them, or the week they’re out sick and the phone goes back to ringing in your pocket. I’m not going to put a number on those extras because they vary too much by state and by how you run payroll. Just know the wage is the floor, not the total.

There’s also a cost that never shows up on a pay stub: your time managing them. Somebody has to show them how you price a service call, which customers get a callback from you personally, and what to say when a homeowner asks if you can come today. For a two or three truck shop, that somebody is you.

None of that makes hiring a bad idea. It just means the honest comparison is about $1,580 a month plus extras plus your time, not “$18 an hour.”

02Which 20 hours you are actually buying

Here’s the part most owners don’t think about until after they’ve hired.

A part-time person covers part of the week. If your phone is live from 7am to 6pm Monday to Friday, that’s 55 hours. Twenty hours of coverage is about 36% of that. A week has 168 hours in total, so even if your business line were only ever called during working hours (it isn’t), you would still have 113 hours with nobody assigned to answer.

So the real question becomes which hours. Mornings, when people discover the leak? Late afternoon, when they get home and notice the AC is blowing warm? Most owners pick the busiest block, which is sensible, and then discover the calls they were losing were spread across the whole day. We wrote about that pattern in the daytime missed call nobody talks about. The short version is that a phone problem in a small shop isn’t usually a single bad hour. It’s a lot of small gaps whenever everyone’s hands are busy.

There’s also lunch. And the day they have a dentist appointment. And the two weeks in summer they’ve had planned since spring. Part-time coverage has holes in it by design, and those holes don’t line up with when customers decide to call.

If you’re not sure where your gaps are, don’t guess. Pull last month’s call log and count. It takes about an hour the first time, and here’s the method. Once you know which hours you’re missing calls in, you’ll know whether a 20 hour person would actually be sitting by the phone when it matters.

03What a person does that software can’t

I’ve built phone systems for trade businesses, and I’ll still tell you this: a good office person does things no answering system will.

They can take a payment in person and chase an unpaid invoice with the right tone. They know Mrs. Alvarez has called four times this year and always wants the same tech. They notice the supplier shorted the order, order the part, and rearrange tomorrow’s schedule around it. They can read a nervous caller and decide this one needs the owner to call back today, not tomorrow. They can tell a customer with a real emergency to hang up and call 911 and then ring you on your cell.

That last bit is judgment, and judgment is the thing to protect. A good hire grows into your business. After six months they know your prices, your crew, your regulars and your bad customers. That’s worth a lot, and no vendor should pretend otherwise.

The catch is that most of that value isn’t about answering the phone. It’s office work. If what you really need is someone to run scheduling, invoicing and parts, hire the person. The phone is part of their job, and they’ll handle it well when they’re at their desk.

But if what you need is mainly “somebody answers when we can’t,” you’d be paying for a whole person to cover one narrow job, and that person still can’t be there at 7pm on a Sunday.

04What automating the phone actually means

“Automate the phone” covers everything from a better voicemail greeting to a fully staffed answering service, so it’s worth being exact about what’s in the box.

Here’s what a decent setup does, and you can use it as a checklist for anybody you talk to. It answers your calls when your team can’t, replies to texts, and helps customers book the next step. The AI handles routine conversations: who’s calling, what’s wrong, the address, when they’re free. Anything that needs attention goes to a person.

If a customer doesn’t book, an approved follow-up asks about the next step, and it stops the moment they reply. If a question needs your judgment, it goes to the person you named, and the answer goes back to the customer.

Here’s what it doesn’t do, and this matters more than the feature list. It doesn’t diagnose a problem. It doesn’t quote a price. It doesn’t promise scope or coverage on your behalf. Appointments wait for you to confirm them, because a fake booking costs you a truck roll and half a Saturday. I explained why that line matters in why an AI should never book a job without confirming it first. It also won’t keep someone talking about a gas smell. It tells them to get out and call 911 or the gas company from outside, and the call goes to a human number.

So automation isn’t a receptionist. It’s coverage. It makes sure the call gets answered, the details get written down, and nobody falls through the crack between “they called” and “someone called them back.” The decisions stay with you.

05Side by side, honestly

Put the two options next to each other and the tradeoff gets clearer.

A part-time receptionist costs about $1,580 a month in wages at the national median, plus payroll extras and your training time. They cover the hours they’re scheduled. They can do office work, take payments and use judgment. They get better with time, and they can quit.

An automated front desk covers the hours a person can’t: lunch, evenings, weekends, the three calls that land at once. It doesn’t take sick days. It also can’t run your office, can’t take a deposit at the counter and won’t make a judgment call. Anything that needs one goes to you or your named person.

On price, I’m not going to put a monthly fee next to $1,580 and say automation wins. They’re different purchases. One buys you an employee for 20 hours a week. The other buys you an answered phone and follow-up around the clock, with no office work at all.

If you want to see where a traditional answering service and plain voicemail fit, we did that comparison in answering service, AI or voicemail. And if you’re curious about the very cheap end of the market, what you get for 29 dollars a month is honest about where the self-serve tools work fine.

One more thing worth saying out loud. Speed matters here, though the best research on it is about web forms, not phones. When Harvard Business Review audited 2,241 US companies on how they handled web inquiries, only 37% replied within an hour and 23% never replied at all. That’s not a phone study, so don’t read it as your answer rate. I mention it because it shows how ordinary it is for a business to let inquiries sit without anyone noticing. Whichever option you pick, the goal is that nobody waits.

06How to decide for your shop

Most owners I talk to land in one of three places.

The first is the shop that’s drowning in office work. Invoices are late, the schedule lives in the owner’s head, and parts orders happen at 10pm. That shop needs a person. Hire the receptionist, give them the phone during the hours they’re in, and make sure your voicemail or your overflow covers the rest so you don’t undo their good work at 5:01pm.

The second is the shop where the office is fine but the phone is the leak. The owner or a spouse handles the books, but calls get missed whenever everyone is on a job. That shop usually doesn’t need an employee. It needs the phone answered when nobody can get to it, and a reliable follow-up for the customers who asked about a job and went quiet. That’s what automation is for.

The third is the shop that needs both, and honestly, that’s common once you get past four or five trucks. A person runs the office during the day, and the automated layer catches the overflow, the lunch hour and everything after close. The person stops being interrupted every six minutes, and the calls they couldn’t take still get handled.

Whichever group you’re in, decide from your own numbers. Count the real calls you got last month, note which ones nobody answered and when, and look at how many of the answered ones turned into jobs. We go through that in the one number every contractor should know about their phone. If most of your misses are during hours a part-timer would be working, the hire might fix it. If they’re spread across evenings, weekends and the middle of jobs, a person won’t be there for them.

And whatever you choose, don’t let anyone, a vendor or an employee, quote prices or promise dates you haven’t approved. That’s the fastest way to turn a missed call into an angry one.

Frequently asked questions

Is an AI cheaper than a part-time receptionist?

Sometimes, but it’s the wrong first question. At the median wage, 20 hours a week is about $1,580 a month before payroll extras. Automated options range from cheap self-serve tools to managed services. Compare what each one actually covers, not just the monthly figure.

Can automation replace my office manager?

No. It answers calls, takes details, replies to texts and follows up. It doesn’t run your schedule, take payments, order parts or make judgment calls. If you need those things done, you need a person.

Will customers know they’re talking to an AI?

They should. The AI says it’s an AI if someone asks, and it should never pretend otherwise. If you want to know how callers tend to react, we wrote about it in do customers mind talking to AI on the phone.

What happens to calls my receptionist can’t get to?

That depends on what you’ve set up behind them. Most phone systems can forward unanswered calls after a few rings to voicemail, another number or an answering system, while your business number stays the same. Check that the overflow actually works before you rely on it.

Can I try automation without committing?

It depends on the vendor. Whoever you look at, ask for a trial on your real calls rather than a slideshow.

The bottom line

A part-time receptionist buys you a person for part of the week, and a good one is worth it if you need office work done. Automation buys you an answered phone whenever your team can’t get to it, plus follow-up, and it leaves every decision with you. Plenty of shops end up with both. Count your calls first and let that tell you which gap you actually have.
