Where I'm coming from: my company handles phones, dispatch, and office work for home service businesses, so I'm not a neutral party. That's why every price below links to the vendor's own page, and there are no affiliate links in this guide.
If you run an HVAC, plumbing, or cleaning company, you already know the problem. The phone rings while you're on a job, with a customer, or driving, and you can't pick up. Hiring a full-time person feels like a big step, so most owners start looking at virtual receptionists and answering services. Then they find out the pricing is hard to compare.
I've spent more than 25 years in customer service, sales, and operations. In this guide I'll walk through what the published prices actually are, how each company bills you, and how to estimate your own monthly cost before you talk to a salesperson.
The short answer
- Live virtual receptionists: Ruby's published plans run from $250 a month for 50 minutes to $1,725 a month for 500 minutes. Smith.ai's live receptionist plans run from $300 a month for 30 calls to $2,100 a month for 300 calls.
- AI receptionists: Smith.ai's AI receptionist has a free plan for 25 calls a month, and paid plans start at $150 a month for 75 calls.
- An in-house receptionist: the U.S. median wage was $18.27 an hour, or $38,010 a year, in May 2025 (BLS). That's before payroll taxes and benefits.
The three ways you get billed
Answering services don't all bill the same way, so comparing their headline prices directly can mislead you. Before you look at any price, figure out which of these models you're looking at.
- By the minute (live people). Ruby sells plans by receptionist minutes per month. Long calls use up your plan faster. If a customer takes four minutes to describe a problem and give an address, that's four minutes.
- By the call (live people). Smith.ai's live receptionist plans include a set number of calls, with a per-call charge above that. Extras like booking appointments or a dedicated Spanish line are charged per call on top.
- By the call (AI). AI receptionists like Smith.ai's AI plan charge a much lower per-call rate. You can pay extra to send a call to a live person when the AI can't handle it.
Published prices, side by side
These are the monthly list prices on each company's pricing page as of October 23, 2026. Taxes, discounts, and custom plans aren't included.
Ruby (live receptionists, billed by minutes)
| Plan | Monthly price | Effective cost per minute | Each extra minute |
|---|---|---|---|
| 50 minutes | $250 | $5.00 | $5.40 |
| 100 minutes | $395 | $3.95 | $4.50 |
| 200 minutes | $720 | $3.60 | $4.40 |
| 350 minutes* | $1,210 | $3.46 | $4.25 |
| 500 minutes | $1,725 | $3.45 | $4.00 |
Per-minute cost is my math (price divided by minutes), assuming you use the whole plan. Ruby's pricing page says 24/7 coverage, bilingual answering, scheduling, and payment collection are available on every plan with no setup fees. Ruby's help center lists the overage rate for each plan (the "each extra minute" column) and says calls are billed in 60-second increments, rounded up, so a 10-second call counts as a full minute. *The 350-minute plan is listed in Ruby's help center but not on its main pricing page.
Smith.ai (live receptionists, billed by calls)
| Plan | Monthly price | Calls included | Each extra call |
|---|---|---|---|
| Starter | $300 | 30 | $11.50 |
| Basic | $810 | 90 | $10.50 |
| Pro | $2,100 | 300 | $8.50 |
Per-call add-ons listed by Smith.ai include appointment booking ($1.50), a dedicated Spanish line ($1.00), and text or email follow-up ($0.50). Smith.ai says it doesn't charge for spam calls on these plans, the service is month-to-month, and paying for 12 months gets a 10% discount.
Smith.ai AI receptionist (billed by calls)
| Plan | Monthly price | Calls included | Each extra call |
|---|---|---|---|
| Free | $0 | 25 | $3.00 |
| Pro | $150 | 75 | $2.50 |
| Pro | $270 | 150 | $2.30 |
| Enterprise | $500 | 300 | $2.17 |
| Enterprise | $800 | 500 | $2.10 |
Smith.ai bills a live-agent add-on at $3.00 per call, only on calls where it's used. Cancelling an AI plan takes 30 days' notice. On AI plans, answered calls count toward your quota, but you can remove up to 10% of them each cycle as spam.
What an in-house receptionist costs
The Bureau of Labor Statistics reports a median wage of $18.27 an hour ($38,010 a year) for receptionists in May 2025. That's the national median. South Florida wages can be higher or lower, and the CareerOneStop salary tool linked in the sources lets you check by ZIP code.
Wages aren't the whole cost. BLS also reports that in private industry in June 2026, wages and salaries made up 70.0% of what employers spend on compensation, and benefits made up the other 30.0%.
Rough estimate, not a quote: if a receptionist's benefits followed that same 70/30 split, $38,010 in wages would mean about $54,300 a year in total compensation cost ($38,010 ÷ 0.70), or about $4,525 a month. Your real number depends on the wage you pay, your benefits, and your taxes. This also leaves out hiring, training, and covering sick days and vacations.
One person also covers one shift. Calls at 7 p.m. or on a Saturday still need a plan, and those are often the calls home service customers make when something breaks.
How to estimate your own monthly bill
The most useful number here is one you already have: your own call volume. Here's how I'd work it out.
- Pull 30 days of call history from your phone carrier or business phone app. Count all incoming calls, including ones you missed.
- Note the average call length if your carrier shows it. This decides whether per-minute or per-call pricing is cheaper for you.
- Mark which calls come after hours and on weekends. Those are the ones you'll most want covered.
- List what you want done on each call: take a message, book the job, quote a service fee, or send emergencies to the on-call tech. Each one can change the price.
A worked example (made-up numbers, for the math only)
Say your call log shows 120 calls a month that average 3 minutes each, or 360 minutes in total. These are example numbers, not industry averages. Using the published prices above:
| Option | How it's calculated | Monthly cost |
|---|---|---|
| Smith.ai AI receptionist | Pro 150-call plan covers 120 calls | $270 |
| Smith.ai live, Basic | $810 for 90 calls + 30 extra calls × $10.50 | $1,125 |
| Ruby, 350 minutes | $1,210 for 350 minutes + 10 extra minutes × $4.25 | $1,252.50 |
| Smith.ai live, Basic, booking every call | $1,125 + 120 bookings × $1.50 | $1,305 |
| In-house receptionist (estimate) | BLS median wage plus the 70/30 benefits split above | ~$4,525 |
On Ruby's other plans, the same 360 minutes would cost $1,424 on the 200-minute plan ($720 + 160 × $4.40) or $1,725 on the 500-minute plan. The Ruby figures assume 360 billed minutes; because Ruby rounds each call up to the next minute, your billed total can be higher than your call log's average suggests. Change any input and the ranking can change, so run your own numbers.
An in-house person costs the most, but they can also do much more than answer phones. That's the real decision: are you buying call coverage, or someone to run the office?
Questions to ask before you sign
- What's the overage rate, and what happens when I go over? Do I get bumped to a bigger plan?
- Do spam calls, wrong numbers, and robocalls count against my minutes or calls?
- How do you handle after-hours emergencies? Can you reach my on-call person, and what happens if they don't answer?
- Can you book jobs directly into the software I use (Jobber, Housecall Pro, ServiceTitan), or only into a general calendar? Smith.ai lists Calendly and Acuity, for example.
- Is Spanish included or extra? In South Florida, this matters.
- What are the contract and cancellation terms, and is there a money-back period?
- Will callers hear my business name and get the same answers my team would give on pricing and service area?
What an answering service usually won't do
A virtual receptionist solves the phone problem. In my experience, missed calls are only part of what keeps owners in the office at night. Here's what usually falls outside a standard answering plan, so check before you assume it's included:
- Deciding which tech goes where and rearranging the day when a job runs long
- Following up on estimates that haven't been approved
- Sending invoices and chasing unpaid ones
- Asking happy customers for reviews
- Keeping customer records and job notes clean in your field service software
If all you need is someone to pick up and take a good message, one of the services above may be the most affordable fix, and I'd tell you that. If the phones are just the start, it's worth comparing those prices with having one team handle calls, dispatch, follow-ups, and invoicing together.
