What is the best answering service for a small business?

For most salons, clinics, trade businesses and restaurants that take bookings by phone, the best value is an AI answering service that books straight into your calendar. Published plans from Dialzara, Rosie, Goodcall and Smith.ai run from $0 for 25 calls to $800 for 500 calls a month. Choose a live human service such as Ruby, Smith.ai or AnswerConnect when a caller needs a person: a clinical after-hours line, an upset customer, or a consult that takes judgement.

The way to decide is the cost of each appointment that actually lands on your calendar, not the cost per minute. A $99 plan that books 30 visits beats a $720 plan that hands you 30 messages to return, unless the people behind the $720 plan win bookings the software would have lost. This guide gives five tests, the published prices, who each service suits, and a worked example you can redo with your own numbers.

How to choose an answering service

Run these five tests against your own phone line before you compare vendors.

1. Do your calls end in a booking or a message? Pull two weeks of calls and sort them. A dental practice's after-hours calls are often pain, insurance and callback requests. A barbershop's are almost all "can I get in Saturday". If most of your calls are booking requests, a service that only takes messages leaves the real work for the next morning, by which time some callers have booked elsewhere.

2. What share of missed calls come after close? If the desk misses calls mainly at lunch and checkout, you need a few hours of overflow cover. If most misses come after close, you need evening and weekend cover. Human services charge the same rate either way, so heavy after-hours volume makes them expensive fast.

3. Can it write into the booking system you run? Most comparisons skip this test. The integrations named on these pricing pages are mostly general schedulers. Smith.ai's human booking add-on names Calendly, Acuity, Appointy and Harmonizely, and its AI plans name Calendly "& more". My AI Front Desk connects through Zapier. Dialzara names Google and Outlook calendar sync, starting on its $99 Pro plan. Rosie's help centre names Google Calendar, Calendly, Acuity and Appointlet (Rosie scheduling help, checked 2026-10-27), and Ruby names no calendar at all. If your book lives in Vagaro, Square Appointments, Booksy, Mindbody, Jane or OpenTable, ask each vendor to show a booking landing in that system, with the right service length and staff member, before you pay.

4. Which languages do your callers use? Rosie lists English and Spanish, and Dialzara adds Spanish from its $99 Pro plan. My AI Front Desk claims "20+ languages". Ruby offers Spanish and bilingual handling, and Smith.ai's human plans charge $1.00 per call for a Spanish line. If a third of your callers speak Vietnamese, most of this list fails, so ask that question first.

5. What does each booked appointment cost? Divide the monthly bill by the appointments that end up on your calendar from those calls. That one number lets you compare a per-minute human plan with a per-caller AI plan fairly.

Published prices side by side

The billing units matter more than the headline prices. Our AI receptionist cost guide explains each one, plus the overage, SMS and setup costs outside the plan card.

The live human services

Ruby suits an owner-run business whose callers expect a warm human voice and whose volume is low and steady. It answers live 24/7, including weekends and holidays, and lists no fees for activation, onboarding or setup (ruby.com/pricing, checked 2026-10-26). The minute bundle is the weak spot. The 50-minute plan works out at $5.00 a minute and the 500-minute plan at $3.45, and no overage rate is published. Get that rate in writing, and ask which booking systems Ruby's receptionists can schedule into.

Smith.ai's human receptionists suit longer, more involved calls, because a one-minute call and a twelve-minute call cost the same. New-patient intake at a clinic or a contractor scoping a job fits that shape. Plans are staffed 24/7 with no setup fees, and spam is not charged if the forwarded line passes caller ID (smith.ai/pricing/receptionists, checked 2026-10-26). The CRMs it names are HubSpot, Salesforce and Clio, which places its core market closer to professional services than to a nail bar.

AnswerConnect has the lowest published per-minute price of the three human services. One detail is worth knowing. The $395 Growth plan carries 300 minutes, no setup fee and a $1.85 overage, while the $350 Entry plan carries 200 minutes, a $49.99 setup fee and a $2.50 overage. Unless you are sure you will stay under 200 minutes, Growth is the better first month. AnswerConnect rounds every interaction up to the next whole minute, so a 70-second call bills as two (answerconnect.com/plans-direct, checked 2026-10-26). Its plans page does not mention Spanish.

The AI answering services

Smith.ai's AI Receptionist suits a quiet line that wants a human safety net. The free plan covers 25 real calls a month, and Smith.ai says a complex call can be transferred to a live receptionist in North America at any hour. It requires 30 days' notice to cancel (smith.ai/pricing/ai-receptionist, checked 2026-10-26). Per-call pricing makes it one of the dearer AI options as volume grows.

Dialzara has the cheapest paid entry and lists no setup fees. Google and Outlook calendar sync and English and Spanish answering start on the $99 Pro plan, not the $29 Lite plan (dialzara.com/pricing, checked 2026-10-26). It suits a solo operator or small trade business with short calls.

Rosie suits a bilingual English and Spanish line with high minute volume. Watch the tier split. The $49 plan texts the caller a booking link, and booking directly on your calendar starts at $149 (heyrosie.com/pricing, checked 2026-10-26). For an appointment business, $149 is the real starting price, and our Rosie vs LLDTEK comparison lists the four schedulers that plan books into.

My AI Front Desk suits a business that wants voice, chat and SMS in one plan and already runs its tools through Zapier (myaifrontdesk.com/pricing, checked 2026-10-26).

Goodcall suits a line where regulars call more than once about the same visit. It counts each phone number once a month and ignores spam and wrong numbers (goodcall.com/pricing, checked 2026-10-26), so a client who rings to book, again to move it, and again about parking counts once.

What is the cheapest answering service for a small business?

On published prices, the cheapest AI option is Smith.ai's free plan if you take fewer than 25 calls a month, then Dialzara at $29 for 60 minutes, though that plan cannot sync a calendar. The cheapest human plan to start is Ruby at $250 for 50 minutes. Per minute, AnswerConnect's Growth plan is the cheapest human service here, at about $1.32 a minute against $3.60 on Ruby's 200-minute plan.

A cheap plan only saves money if it does the job. Rosie's $49 plan sends a link instead of booking, and a link the caller never opens is a lost appointment. For a booking business, the cheapest plan worth considering is the cheapest one that writes the visit into your calendar at your real volume.

A worked example of cost per booked appointment

This business is a composite example built from common setups, not a named LLDTEK customer. Every volume figure is an assumption chosen to show the method.

A two-practitioner physiotherapy clinic sends 80 calls a month to its answering service: lunch, overflow while both practitioners are with patients, and calls after close. Calls average two and a half minutes, or 200 minutes in total, and come from 70 different numbers. Forty are booking requests. Assume 30 of those end on the calendar, whichever service answers.

The AnswerConnect line assumes each call rounds up to three billed minutes. The Smith.ai human line assumes the $1.50 booking add-on applies only to calls where an appointment is booked; confirm that with Smith.ai. All rates come from the pricing pages above, checked 2026-10-26.

The table is not the verdict, because equal bookings across every service is the assumption doing most of the work. A good human receptionist may keep a caller who would have hung up on software. So ask how many extra bookings a month the human service must win to cover its price gap.

Take Ruby against Dialzara. The gap is $621 a month. If an average visit is worth $85 (an assumption, so use your own figure), Ruby has to win about eight more appointments a month than the AI to break even. Some businesses clear that easily. Our missed-call revenue calculator estimates what your missed calls are worth now, which tells you how much room there is. And if only 10 of your 80 calls were booking requests, the AI's advantage shrinks, and a human taking good messages may be the simpler buy.

When a human service is the better buy

Buy the human line when the conversation is the job, rather than the booking.

A clinic's after-hours line where callers describe symptoms needs a trained person who follows your on-call protocol and pages the clinician. Software should not triage that call. We cover that split in An answering service takes a message. A clinic needs a booked room.

A human service also wins when calls are rarely bookings, such as a plumber whose callers want to describe a leak, or a business whose callers are often upset. It wins when you take a handful of calls a month and want a person answering in your name with nothing to configure. And it wins when an insurer or medical director requires a person on certain calls.

Many businesses run both: a human service on the urgent path and an AI on the booking line. That only works if "press 2 if this is urgent" reaches a person every time.

Where LLDTEK fits

LLDTEK runs AI agents for appointment businesses. The front desk agent answers calls and texts when nobody on staff is free, and works the booking system or POS you already run, such as Vagaro, Square, Booksy, Zenoti, Mindbody or OpenTable. Voice, SMS and web chat share one thread, so a caller who switches to text does not start over. We set the agents up with you, so you never write prompts, and your desk person stays.

We do not publish a price. We quote after a 30-minute demo against your own book that covers your hours, call volume, languages and which calls should go to a person. Bring the languages your callers actually use, and we test them on the call. Nobody is billed until you have seen the agents run a live day with us.

That model costs you half an hour before you see a number, while every AI plan in the table shows its price up front. If you take 30 calls a month into a single calendar, a self-serve plan will probably be quicker and cheaper. If your clinical line needs a human, buy the human service for that line. LLDTEK fits best where several staff calendars, service lengths and languages make a wrong booking expensive, and where you want the system that holds your book to stay in charge. Whatever you shortlist, run the calls in What to test on an AI receptionist demo first.
