A law firm answering service costs roughly $250 to $2,100 a month in published US pricing, depending on how many calls or minutes you use. Ruby charges $250 a month for 50 receptionist minutes and $1,725 for 500. Smith.ai charges $300 a month for 30 calls and $2,100 for 300. Several legal-specific providers, including Answering Legal and Alert Communications, do not publish a number at all and quote after a form. Those are the real 2026 figures, read off each vendor's own pricing page, and the spread between them is mostly about how the meter runs rather than how good the service is.

What law firm answering services actually charge
The category splits into two billing models, and the model matters more than the sticker price. Live receptionist services bill by usage: minutes at Ruby, calls at Smith.ai. AI answering services usually bill per call. A small number of intake platforms bill a flat rate by firm size. Here is what is publicly published as of July 2026.
| Provider | Published monthly price | What you get |
|---|---|---|
| Ruby (live receptionists) | $250 / 50 min, $395 / 100 min, $720 / 200 min, $1,725 / 500 min | Live US receptionists 24/7, your greeting, messages forwarded. Chat plans from $143/mo |
| Smith.ai (human receptionists) | $300 / 30 calls, $810 / 90 calls, $2,100 / 300 calls | Live humans; intake capped at 5 questions; extras billed per call |
| Smith.ai (AI receptionist) | $150 / 75 calls, $270 / 150 calls, $500 / 300 calls | AI answering, billed per call |
| Answering Legal | Not published, form-gated quote | Legal-specific live answering; pricing shown only after you submit a form |
| Alert Communications | Not published | High-volume legal intake center, quoted per firm |
| In-house receptionist | About $45,000 salary, $55,000 to $75,000 loaded | Roughly 40 hours a week, one call at a time, no nights or weekends |
| Consultations | $49 solo, $129 up to 5, $299 up to 20 | AI runs the full intake, screens the matter, books the consult, briefs the attorney. Flat per firm |
Two things stand out in that table. The first is how many legal-specific vendors will not tell you a price without a sales conversation, which makes budgeting a research project. The second is that the published prices are for answering, not for intake. That distinction is where most firms get the math wrong.
The per-call extras nobody quotes you up front
The headline price buys someone picking up the phone. Anything resembling actual intake is usually metered on top. Smith.ai publishes its add-on rates openly, and they are a good map of how the category prices the work: booking an appointment adds $1.50 per call, a conflict check adds $0.50, taking a payment adds $1.00, and extended intake beyond the included five questions adds $1.50 for the next six questions and then $0.25 per additional question after that.
Read that again, because it explains the whole economics of the category. Five intake questions are included. A real legal intake, the kind that establishes practice area, what happened, when it happened, whether a deadline is near, who the opposing parties are, and what documents exist, is fifteen to twenty-five questions. Metered per question, a properly qualified call costs several dollars more than an unqualified one, so the service is financially discouraged from doing the thing you actually want. Firms respond by keeping the script short, which produces messages instead of qualified matters.
Why minute-based pricing punishes your best months
The other trap is that usage-based pricing scales with your marketing, not with your revenue. A firm running $6,000 a month in advertising generates calls, and a good month generates more of them. At $250 for 50 minutes, a burst of interest after a campaign flight or a local news story pushes you into a higher tier, and the answering bill goes up in exactly the month you spent the most to make the phone ring. If those calls converted, fine. If half of them were people outside your practice area, you paid by the minute to have a stranger take a message from someone you were never going to represent.
This is worth modeling before you sign. Take your call volume from the last three months, take your average call length, and price it against the tiers. Then ask what happens above the tier, because overage rates are frequently not published. Ruby's pricing page states there are no activation, onboarding, setup, or customization fees and lists plans by included minutes, but does not publish an overage rate, so get that number in writing. The same goes for how partial minutes are rounded, whether spam and wrong-number calls are billed, and what the minimum billable increment is. Those three details routinely move a real invoice 20 percent above the quoted plan.
Answering versus intake: what the money is really for
A missed call is not the expensive part. The expensive part is the delay between the call and a qualified answer. A prospective client with an urgent legal problem calls several firms and retains the one that responds first with something useful. If your answering service takes a message at 7pm and your paralegal calls back at 10:40 the next morning, you have paid for coverage and still lost the race.
| What happens on the call | Live answering service | AI intake agent |
|---|---|---|
| Someone picks up 24/7 | Yes | Yes |
| Full intake questions asked | Usually capped, then metered per question | Yes, as many as the matter needs |
| Matter screened against firm criteria | No, you screen on the callback | Yes, during the call |
| Conflict-check names captured | Often a paid add-on | Yes, and flagged at the top of the brief |
| Documents collected | No | Yes, requested and chased |
| Consultation booked | Sometimes, billed per booking | Yes, on the right attorney's calendar |
| Cost of a high-volume month | Higher | Unchanged |
That is the honest comparison. A live service wins on warmth, and a caller in distress can usually tell they are talking to a person, which matters more in some practice areas than others. An AI receptionist for law firms wins on completeness: it asks the full set of questions, applies your screening rules identically every time, and books the meeting rather than handing the task back to you. If you want a side-by-side on the specific vendors, our Ruby Receptionists alternative comparison lays out where each model actually fits.
How to price this for your own firm
Work it out per signed matter rather than per month, because that is the only number that tells you anything. If you take 120 inbound calls a month, 30 are in your practice area, and you sign 6, then a $720 answering plan costs $120 per signed matter. That is cheap if your average matter is worth $8,000 and expensive if you run a high-volume, low-fee practice. Run the same math against a flat-rate intake platform and against the loaded cost of a receptionist, which is not the $45,000 salary but the $55,000 to $75,000 you actually spend once payroll taxes, benefits, equipment, and paid time off are counted. Then compare what each option leaves on your desk at the end of the call.
One more line item people forget: what you spend generating the calls in the first place. Before you optimize a $400 answering bill, check whether the campaigns feeding it are producing inquiries in your practice area at all. Firms that see exactly which ads their competitors are running often find the cheaper fix is upstream, in the targeting, rather than in the cost of answering calls they should never have received.
Questions to ask before you sign anything
The vendors that publish pricing openly, Ruby and Smith.ai among them, deserve credit for it. For everyone else, insist on written answers to these before a contract: What is the overage rate, exactly? Are minutes or calls the billing unit, and what is the minimum increment? Are spam calls, wrong numbers, and hangups billed? How many intake questions are included, and what does each additional one cost? Is appointment booking included or an add-on? Is there a setup fee or a term commitment, and what does cancellation require?
Six clear answers to those questions will tell you more about your real annual cost than any published starting price. And if a vendor will not answer them in writing before you sign, that is itself the answer. For the broader category, including intake platforms rather than answering services, our guide to how much legal intake software costs covers the vendors that sell the software rather than the phone coverage. If you are weighing AI coverage against a live service or a hire, we put every published price in the category side by side on the best AI receptionist comparison, and worked through the loaded cost of a front desk hire in how much a receptionist costs.
