Smith.ai, Ruby, GoodCall, and human services compared by pricing model: per-call, per-minute blocks, flat monthly, and pay-as-you-go AI at ~6¢/min.

If you are shopping for Smith.ai alternatives, Ruby Receptionist alternatives, or GoodCall alternatives, the brand names matter less than the billing model underneath them. Per-call plans, per-minute subscription blocks, and flat monthly services nearly all charge you for capacity whether your phone rings or not — Smith.ai's free AI tier, capped at 25 calls a month, is the one exception here. Pay-as-you-go AI charges only for answered seconds, which is why the same quiet month can cost $5.50 against plan minimums that run from $79 to $300.

Nobody shops for an answering service alternative because things are going well. Something specific happened: an invoice arrived with spam calls billed at full rate, a quiet month still cost the full plan minimum, or a caller got a message taken when they wanted an answer. The switch decision gets easier once you name which of those it was, because each competitor's pricing model produces a different failure mode.

This article compares the four models on the market, with the vendors who use each, honestly, including what they genuinely do well.

## Per-minute subscription blocks: Ruby and the human receptionists

Ruby built its name on warm, professional human receptionists who learn your business and sound like your front desk. That is a real product and they are good at it. The billing model is a monthly bundle of receptionist minutes: $250 a month for 50 minutes, $395 for 100, $720 for 200, verified on Ruby's own pricing page on 19 August 2026. Past the bundle you pay an overage rate Ruby does not publish anywhere — its FAQ says only that additional minutes are billed at the rate associated with your plan, so the cost of your 51st minute is not knowable before you sign.

The failure mode that sends people shopping: the bundle charges in quiet months and the overage charges in busy ones, and human minutes are priced like human wages because they are. If your calls genuinely need a familiar human voice (sensitive legal or medical intake, clients who expect a named person), Ruby earns the premium. If most of your calls are "what time do you close" and "can I book Thursday," you are paying human rates for machine-simple work.

## Per-call plans: Smith.ai and the hybrid model

Smith.ai prices per call, on tiers that bundle a number of calls per month, and it sells two separate products that most comparison pages collapse into one. The AI receptionist tiers are $0 a month for 25 calls, $150 for 75 and $500 for 300, with extra calls at $3.00, $2.50 and $2.17. The human virtual receptionist tiers are $300 for 30 calls, $810 for 90 and $2,100 for 300. That free tier is a real plan rather than an expiring trial, and under 25 calls a month it is the cheapest thing in this article. What Smith.ai does well beyond price is integrations: their receptionists plug into CRMs, calendars, and intake workflows deeply, and for a business living in its CRM that plumbing is worth real money.

The per-call failure mode is the unit itself. A wrong number, a robocall, and a four-minute intake can all count as one billed call, and short calls get no discount. Businesses whose phones attract junk feel this first, because a third of the invoice can be calls nobody wanted answered.

## Flat monthly AI subscriptions: Goodcall and the per-caller meter

GoodCall represents the newer shape: an AI agent on a flat monthly subscription at $79, $129 or $249 a month per agent. What it meters is unusual and worth understanding — not minutes and not calls, but unique callers. Minutes are unlimited, and one phone number that rings you nine times in a month counts once, with $0.50 for each unique caller past the plan's allowance of 100, 250 or 500. The AI handles the routine call types well and the flat price is predictable, which is the pitch. Predictability cuts both ways, though: you pay the tier in the slow month, and a wide funnel of first-time callers burns the allowance fast even if none of them talks for long. On the $79 Starter tier, spread across its full 100-caller allowance, [the break-even against per-second billing](/hub/dial-milo-vs-goodcall) works out to about 13 minutes of talk time per caller — below that, pay-as-you-go is cheaper outright.

## Pay-as-you-go AI: the outlier

The fourth model drops the subscription entirely. Dial Milo bills per second of answered call time at about 6¢ a minute on a US number (roughly 2.6¢ carrier plus 3.5¢ AI), with no monthly minimum and no charge for missed, blocked, or spam calls. A dedicated number costs $3 a month, or forward your existing one free. Sixty 90-second calls in a month is 90 answered minutes: about $5.50, total.

The trade is that there is no human in the loop. What you get instead is an AI that answers on the second ring in multiple languages, books into your connected calendar, answers questions from documents you upload, refuses to quote prices it was not given, and texts you a summary the moment a call is urgent. For businesses whose call volume is unpredictable, which is most small businesses, funding zero idle capacity is the whole argument.

## What a switched call sounds like

A caller who used to reach your old service's message-taker:

> **Milo:** Thanks for calling Hartley Electrical, this is Milo. How can I help?
>
> **Caller:** Hi — do you guys do EV charger installs, and what does that run?
>
> **Milo:** We do install EV chargers. I don't have a price I can quote you for it, since it depends on your panel and the run to where you park, but I can book you a free estimate. Would that help?
>
> **Caller:** Yeah, okay. Sometime next week?
>
> **Milo:** I have Tuesday at 10am or Wednesday at 2pm with Dan. Which works?
>
> **Caller:** Wednesday.
>
> **Milo:** Booked for Wednesday at 2pm. Can I grab your name, address, and the best number in case anything changes?

Two things the old message-taker did not do: it declined to invent a price rather than guessing one, and the caller hung up with an appointment instead of a promise someone would call back. That difference, not the voice, is usually what makes the switch stick.

Do not switch away from a human service if your calls genuinely need one. HIPAA-regulated intake, distressed callers, high-stakes legal screening: a trained human earns its rate there, and saving $390 a month on the wrong call is expensive. The switch case is routine volume, which is most of what most small business phones actually carry.

## What to test before signing

  
    Take last month's answered minutes and calls. Price them per call, per minute, and per second at ~6¢. Ten minutes with your own numbers beats any comparison page, including this one.
  
  
    Not "what are your hours" but the question that made a caller hang up last month. Watch whether the answer comes from your information or gets invented.
  
  
    Ask directly: do spam calls, wrong numbers, and hangups bill? Get it in writing. This single line item is where most switch decisions start.
  
  
    Contract terms, notice periods, and whether you can forward away in five minutes. A service you can leave freely is a service that has to keep earning you.
  

## What this costs in practice

[Dial Milo](/pricing) is the pay-as-you-go outlier in this comparison: about 6¢ per answered minute billed per second, no subscription, no monthly minimum, nothing charged for missed, blocked, or spam calls, and a $1 trial credit that buys roughly 16 minutes of real answered calls. Forward your existing number free and you can run it alongside your current service for a week without canceling anything, which is the lowest-risk way to compare.

The broader us-versus-traditional picture, including where human services genuinely win, is in [Dial Milo vs. a traditional answering service](/hub/dial-milo-vs-answering-service). If your last invoice had a minimum you paid in a month the phone barely rang, multiply your answered minutes by 6¢ and look at the number.

## Frequently asked

**What is the best alternative to Smith.ai?**

Depends on why you are leaving. If per-call billing on short calls is the problem, look at per-second pay-as-you-go AI services like Dial Milo, where a 40-second call bills 40 seconds rather than a full call unit. If you want more human involvement rather than less, Ruby's per-minute receptionist plans go the other direction. Switch on the pricing model, not the brand.

**Can I switch answering services without changing my business number?**

Yes, and you should. Nearly every service, Dial Milo included, works through call forwarding from your existing number, so switching means changing where the forwarding points rather than porting anything. You can run the old and new service side by side for a week by forwarding only unanswered calls, then cut over when the new one proves itself.

**Are Ruby Receptionist alternatives actually cheaper?**

Per-minute human reception is the most expensive model in this market by design, since you are buying a trained person's time, so almost any alternative is cheaper on paper. The honest question is whether your calls need what Ruby sells: warm, familiar humans on sensitive intake. For bookings, hours, pricing questions, and message capture, AI handles the same calls at roughly a seventieth of the cost: 90 minutes of talk is $395 on Ruby's 100-minute plan and $5.50 at Dial Milo's per-second rate.

**Will my callers notice when I switch from a human service to AI?**

They will notice the phone getting answered on the second ring instead of the eighth, and getting answers instead of a message taken. What they notice less than you fear is the voice itself, provided the AI answers from your real information rather than a generic script. Test it yourself with your hardest real question before deciding.

**Can I keep my current service and add an AI service just for overflow?**

Yes, and this is often the smartest switch path. Keep the human service for business hours if you like it, and forward unanswered or after-hours calls to a pay-as-you-go AI. Since per-second billing costs nothing when no calls arrive, the overlay adds coverage without doubling your fixed spend.
