Smith.ai vs Ruby Receptionists: pricing, cost per call and which is cheaper for a law firm

Smith.ai bills per call, Ruby bills per minute, and that single difference decides which one is cheaper for your firm. Read from both vendors' own pricing pages on 30 August 2026, Smith.ai Starter is $300 a month for 30 calls, which is $10.00 per included call. Ruby's entry plan is $250 a month for 50 minutes, which is $5.00 per included minute. Those two rates cross at almost exactly two minutes. If your average call runs longer than that, Smith.ai is cheaper, and legal intake calls essentially never run shorter. If your inbound is mostly quick scheduling traffic from existing clients, Ruby's meter suits you better.

The published prices, side by side

Both companies publish full price cards, which deserves saying plainly: most of this category does not. Lawmatics, Lead Docket and Captorra publish nothing, and Smokeball removed its only figure in August 2026. You can shop these two honestly.

Ruby also sells live chat separately at $143 for 10 chats, $335 for 30 and $520 for 50 a month, and discounts chat by about 20 percent when you bundle it onto a receptionist plan, where the same tiers cost $115, $268 and $416. Smith.ai's top tier, Enterprise, is quoted rather than published.

The crossover sits at about two minutes

This is the calculation that actually decides the question, and neither vendor will do it for you because it involves the other one's price card.

Smith.ai charges the same $10.00 whether a caller talks for thirty seconds or fourteen minutes. Ruby charges by the minute, so the same fourteen minute call costs $70 on its entry plan. Divide Smith.ai's per call rate by Ruby's per minute rate and you get the call length at which the two are identical.

The break even lands between two and two and a half minutes at every tier pairing, which is a remarkably stable answer. Below it Ruby is cheaper. Above it Smith.ai is cheaper, and the advantage compounds because Smith.ai's rate does not move with length at all.

Now ask how long a new client intake call actually takes. Someone describing a car accident, a divorce or a probate matter, being asked what happened and when, and then being booked in, is not a two minute conversation. Five to ten minutes is normal, and the calls you most want to go well are the longest ones. On a five minute average, Ruby's entry plan works out near $25 a call against Smith.ai's $10.00. On a ten minute average it is $50 against $10.00.

Two smaller effects push the same way. Smith.ai does not charge for spam calls at all, while a robocall that reaches a Ruby receptionist consumes billed minutes. And Smith.ai's own marketing leans on this deliberately: it states it will not rush a caller off the phone, which is easy to say when call length is free to you.

Where the comparison turns around: what the price actually buys

If the story ended there Ruby would look badly beaten, and that is not the honest picture. The two vendors sell the plan price very differently.

Ruby's plans are feature flat. In Ruby's own words, the only difference between its plans is the number of receptionist minutes, which means every customer gets the identical feature set whatever they pay. There is no higher tier holding a feature hostage. In a market where tier gating is close to universal, and where we have documented vendors putting HIPAA compliance, intake forms and even a rate card behind a sales call, Ruby not gating anything is genuinely unusual and worth real money to a small firm.

Smith.ai does the opposite and itemizes. The plan price buys an answered call, lead qualification, a dedicated number, the first CRM integration and new client intake capped at five short answer questions. Everything a law firm actually wants on an intake call is priced on top, per call:

Add up the ones a real legal intake call uses, meaning extended intake, four extra questions, a conflict check, booking, taking the deposit, recording, a follow up and one notification, and you get $6.75 of add ons sitting on a $10.00 call. The call costs about $16.75, roughly 68 percent above the headline rate. Our Smith.ai pricing breakdown works through that arithmetic line by line and lists the complete rate card.

Re run the crossover at $16.75 and Smith.ai still wins above about three and a half minutes on Ruby's entry plan. The conclusion survives, but the margin is much thinner than the headline figures suggest, and a firm comparing $300 against $250 is comparing the wrong two numbers.

The questions firms ask before choosing

Is Smith.ai cheaper than Ruby? For legal intake calls, usually yes. Smith.ai's per call meter beats Ruby's per minute meter on any call longer than about two minutes, and intake calls run five to ten. For short, high volume, transactional calls, Ruby is cheaper. The meter matters more than the plan price.

Does Ruby charge extra for appointment booking? No. Ruby's minutes cover whatever the receptionist does during the call, so booking consumes time rather than triggering a fee. Smith.ai charges $1.50 per call to book, plus $1.00 for custom calendaring with more complex rules. For a firm whose whole reason for hiring an answering service is filling the calendar, that fee applies to nearly every successful call.

Which one is better for a solo attorney? Usually Smith.ai on Starter, because a solo practice taking ten to twenty inquiries a month gets 30 calls of any length for $300, and those calls are the long ones. The exception is a solo who wants the warmest possible answer and hates itemized bills, which is exactly what Ruby sells.

Do either of them qualify a legal matter? Partly. Both will screen against criteria you supply, and Smith.ai names lead qualification as an included feature. Neither is running a legal intake in the sense a firm means it: Smith.ai caps free intake at five questions and then charges per question, and Ruby's receptionists take a message and hand off. In both cases somebody at the firm calls back to ask what actually happened.

Are there setup fees? Neither publishes one. Smith.ai states no setup fees, no overseas agents and free porting of your existing number, plus a 30 day money back guarantee that is capped at $1,000. That cap is worth noticing on the Pro plan at $2,100 a month, where it covers under half of one month's spend.

The structural problem neither meter solves

Both of these are good services and either will beat a voicemail box. But look at what the two pricing models have in common: each one puts a meter on the intake conversation itself. Ruby meters the minutes, so a thorough call costs more than a rushed one. Smith.ai meters the questions, so a thorough call costs more than a shallow one.

That has a specific and expensive consequence for law firms. The questions worth asking on intake are not uniformly valuable. Whether the defendant is insured, when the clock on the statute started running, whether the caller has spoken to another attorney: each of these is worth $0.25 on the overwhelming majority of calls and worth an enormous amount on a small handful. Low average value and high occasional value is precisely the profile that per unit pricing trains you to cut, and the calls where you cut it are the ones you needed the answer on most.

The alternative is to take the meter off the conversation. That is what Consultations does: an AI runs the full discovery conversation, asks every question that might matter because the marginal question costs nothing, screens the matter against your criteria, collects the documents, books the paid consultation and hands the attorney a prepped brief. It is priced flat per firm at a planned $49 to $299 a month, though that is planned launch pricing and is not purchasable today. Below roughly ten to fifteen worked calls a month, Smith.ai Starter is genuinely cheaper and we would rather say so than pretend otherwise. We have written up both vendors in more depth on the Smith.ai alternative and Ruby Receptionists alternative pages, including where each of them stays the better buy.

One last thing worth separating out, because firms often blame the answering service for it. Taking a deposit at intake is only the first half of getting paid; the balance still has to be invoiced and followed up, and that is a different job from answering the phone. Practices that stop losing money at this stage generally do it by putting the follow up on a system that chases every unpaid invoice by email and text automatically rather than by asking the receptionist to do more. If your real complaint is aged receivables rather than missed calls, no answering plan on either price card will fix it. And if the complaint is that the calendar keeps filling with people you should never have met, that is a screening problem, which our guide to what legal intake software costs takes apart properly.
