Live Receptionist for a Small Law Firm: Cost and When AI Fits

A live receptionist for a small law firm costs roughly $160 to $2,100 a month from a remote answering service on published plans, against about $4,300 for a full-time in-house hire on illustrative pay. An AI receptionist is enough when calls are routine and no caller needs judgement or reassurance.

Price is rarely the deciding factor. A full-time receptionist covers 40 of the week's 168 hours, a remote service covers all of them, and an AI receptionist covers all of them for far less but can't hear fear in a caller's voice. The useful question is which of your calls need a person, and when.

Vendor figures here come from each vendor's own pricing page, rechecked on 4 November 2026, as USD list prices. Check them before you commit, because per-call add-ons and overage rates can move a real bill by a fifth or more. The in-house figures are illustrative arithmetic, not pay data: replace the hourly wage with what you would actually offer.

One thing sets a law firm apart from a plumber or a salon. The call handler is the first person a prospective client speaks to, so confidentiality and conflict checks begin before any lawyer is involved. Both come after the money below.

Monthly cost at 40, 90 and 200 calls

The table prices five routes at three volumes. For the per-call service it picks the cheapest published plan at each volume, overage included. For the per-minute service it assumes three-minute calls and takes the smallest plan that covers them. Time a sample of your own calls first: intake calls usually run longer than message-taking calls, and per-minute billing charges for every extra minute.

The per-call row follows Smith.ai's published plans. Starter is $300 for 30 calls with extra calls at $11.50, so 40 calls cost $300 plus ten at $11.50, or $415. Basic is $810 for 90 calls with extras at $10.50, which is why it beats Pro ($2,100 for 300 calls) at 200 calls: $810 plus 110 extra calls at $10.50 comes to $1,965. Pro only takes over at roughly 210 calls a month.

The per-minute row uses Abby Connect's published plans: 50 minutes for $164, 100 for $329, 200 for $599 and 500 for $1,380. Its page says overage is billed at your plan's Abby Minute rate but doesn't print that rate, so I have taken it as the plan price divided by its minutes: $3.28 on Starter, about $3.00 on Professional and $2.76 on Growth. Confirm the figure before you sign. Forty three-minute calls need 120 minutes, and Starter plus 70 overage minutes ($394) edges out Essential plus 20 ($395). Ninety calls need 270 minutes, and Professional plus 70 overage minutes comes to about $809, well below the 500-minute plan at $1,380. Two hundred calls need 600 minutes: Growth plus 100 overage minutes, about $1,656. Check your first invoice against this sum, because a different overage rate changes every figure in the row.

The AI row uses Smith.ai's AI Receptionist: free for 25 calls a month and then $3 a call, or Pro at $150 for 75 calls with extras at $2.50. Forty calls cost $45 on the free plan. At 90 calls, Pro plus 15 extras ($187.50) edges out staying free ($195). At 200 calls, the 150-call Pro tier (listed at $1.80 a call, so $270) plus 50 extras at $2.30 comes to $385. The cost side of AI receptionists for law firms is covered in more depth in AI receptionist for law firms: cost and what it must never say.

In-house: the sum behind the headline

An in-house receptionist is the only route whose cost doesn't change with call volume, which makes it look expensive at 40 calls and sensible at 400. The sum has four parts, and a spreadsheet row for each stops the on-costs being forgotten.

Annual cost = hourly pay x paid hours + on-costs + equipment and software + recruiting and training
Monthly cost = annual cost / 12
Hours covered = paid hours on the phone / 168 hours in a week

Take illustrative inputs of $20 an hour, 2,080 paid hours (40 a week for 52 weeks) and on-costs of 25% for employer taxes, benefits, a phone seat and a desk. The annual cost is $41,600 plus $10,400, which is $52,000, or $4,333 a month. At 20 hours a week it halves to about $2,167. Swap in your own figures, and check current pay for the role rather than trusting mine.

Two comparisons matter more than the monthly figure. First, a full-time hire covers 40 of the week's 168 hours, about 24%, and fewer once lunch, holidays and sick days come off, so evenings and weekends still go to voicemail. Second, the hire does other work: greeting visitors, handling post and documents, scheduling. A remote service or an AI does none of that, so the fair comparison is the phone-answering slice of the job, not the whole salary.

That points to a common middle path. Keep a part-time person for visitors and admin, and send overflow and after-hours calls to a service or an AI receptionist. Which one depends on your call mix, as the later sections show.

Answering-service plans: calls versus minutes

Services bill in two ways, and the difference changes which is cheaper for you. Smith.ai charges per call, whatever the length. Ruby and Abby Connect sell blocks of receptionist minutes. Per-call billing protects you from long calls; per-minute billing is cheaper if most calls are short message-taking and dearer if every call runs a full intake.

Read the small print on each. Abby Connect counts a minute answered by its AI as half an Abby Minute, so 200 minutes on a plan stretch to 400 AI minutes, and its page lists month-to-month terms, no setup fee and a free trial on every plan. Ruby doesn't name its plans, so the table uses the page's own descriptions; it lists lead qualification and intake among the included features and says there are no fees for activation, onboarding or setup, but prints no overage rate. Smith.ai is month-to-month, offers new customers a 30-day money-back guarantee (up to $1,000, overage excluded), takes 10% off a 12-month subscription and lets plan changes start the following month.

Smith.ai is the one that prices law-firm extras openly. Lead qualification and new-client intake with five short-answer questions are included, the first CRM integration is free (Clio is named), and its page lists add-ons per call: conflict-check capture at $0.50, six extra intake questions at $1.50, accepting payments at $1.00 and each further CRM at $0.50. A Starter plan with conflict-check capture and extended intake on all 30 calls costs $300 plus 30 times $2.00, which is $360, or $12 a call against the $10 headline. That gap is the fifth the opening warned about.

Four lawyers, 90 calls a month and 30 that go unanswered

Say a four-lawyer firm with no full-time receptionist gets 90 calls a month. The phone log shows 60 from prospective clients and 30 from existing clients and suppliers. Thirty calls a month reach voicemail because everyone is in a meeting or the office is closed, and 18 of those thirty are prospective clients. Assume half of those 18 callers ring another firm, which is nine lost enquiries.

Now add two more assumptions: one in three answered enquiries becomes a booked consultation, and one in three consultations becomes a matter worth $2,500 in fees. Nine lost enquiries then cost about $2,500 a month (9 x 1/3 x 1/3 x $2,500). Every assumption here is a placeholder. The call log supplies the first few numbers, and your intake sheet supplies the conversion rates.

Against that loss, the options look like this. A full-time hire at about $4,333 a month costs more than the whole estimated loss, and a 40-hour contract still leaves evenings and weekends uncovered. A human service on Basic at $810 covers every hour and pays for itself if it recovers a third of the loss. The AI receptionist on Pro at $187.50 costs under a quarter of that and handles the routine calls, but urgent ones need a rule. As a break-even, an $810 plan is covered by one extra $2,500 matter a quarter.

For this firm I would start AI-first with an urgent-call rule (any call touching a deadline, custody or personal safety transfers to a named lawyer and sends a text), read every transcript for the first fortnight, and move to the human plan if several callers a month turn out to need reassurance the AI can't give. A firm with a call log full of distress would reverse that order.

Confidentiality questions to settle before anyone answers your phone

Treat a caller's first minute as confidential from the start. Professional conduct rules can extend confidentiality duties to people who only enquire, so check yours with whoever advises the firm on conduct and brief the provider to match. The working rule for any call handler, human or AI: collect names, contact details and a one-line matter type, and politely stop the story there.

• Will the provider sign a confidentiality agreement before go-live, and does it cover subcontractors?
• Who can listen to recordings and read transcripts, and is that access logged?
• Where are recordings and transcripts stored, for how long, and can you have them deleted on request?
• For an AI service, does any third-party model provider see audio or transcripts, and are they used to train models?
• Are human receptionists employees or contractors, and what training do they get for legal enquiries?
• Does the greeting disclose recording and, for AI, that the caller is speaking to an automated assistant?
• What happens to your data if you cancel?

Ask for security documentation in writing rather than relying on a reassuring sales call. The call handler collects party names; the conflict check itself belongs to the firm, and conflict check software for small law firms shows where AI helps with it. For qualifying enquiries once the call ends, AI client intake for law firms goes further.

An intake script that fits on one screen

A receptionist can't improve on a bad script, and neither can an AI. This one asks six things and nothing more, and it works as a brief for a human service or as the base prompt for an AI receptionist.

Greeting: "Thank you for calling [firm name]. Calls may be recorded. How can I help?"

1. Full name, best phone number (read it back), email address
2. Matter type, one line: [family | estate planning | property | employment | business | other]
3. Full names of any other people or companies involved
   Say: "The lawyers run a routine check before any consultation, so I need the spelling of each name."
4. Any deadline, hearing date or papers served, and when
5. "Is anyone in immediate danger, or is someone in custody right now?" (yes = urgent route)
6. Best time and way to call back, and whether it is safe to leave a voicemail

Never say: whether the firm can take the matter, whether the caller has a case, what a fee will be beyond the published consultation fee, or whether anyone else is a client of the firm.
Close: "A lawyer or the intake team will call you by [time]. If anything changes, call again and say it is urgent."

Three choices in it are deliberate. It asks for other parties' names without explaining more than a routine check, so nobody can be told whether the firm acts for someone else. It reads the phone number back, because one wrong digit loses the enquiry. And the "never say" line is a hard stop, since a call handler who says "you definitely have a case" has given advice on the firm's behalf. Callers in distress need a different opening; AI receptionists for family law firms covers that.

Out-of-hours handover that doesn't drop urgent calls

An after-hours service is only as good as its handover rules. Three categories cover most firms. The response targets are examples; set your own.

Delivery matters as much as the categories. An urgent call should trigger a live transfer, then a text and email to the on-call lawyer, then a second contact after a set number of minutes if nobody responds. A message like the one below gives the lawyer everything in one glance.

URGENT | 21:42 | [first name] [surname] | [phone, read back]
Matter: family | Other party: [name, spelled]
Why urgent: served papers today, response due tomorrow 17:00
Caller safe now: yes | Call back between now and 23:00
Recording: [link]

Keep a one-line log of each urgent call: when it arrived, when a lawyer responded and what happened next. That log is your evidence if a handover ever fails. For callers whose calls went unanswered during the day, a missed-call text-back is a cheap complement to any of the three routes.

When an AI receptionist is enough

The decision rule I would use: if you can list your usual calls on one page and none of the categories needs empathy, judgement or a fast human decision, AI-first is reasonable. If any common call type involves distress, a deadline or personal safety, put a person first, or put the AI first with an automatic transfer to a person. Four typical firms show how that plays out.

A solo estate-planning lawyer in meetings most of the day takes around 25 calls a month, almost all booking requests. An AI receptionist on a free or entry plan costs $0 to $150, and the worst realistic outcome is a rescheduled call.

A four-lawyer general practice with 90 calls a month is the firm in the worked sums above: AI-first, an urgent-call rule, and a weekly transcript review until the rule has proved itself.

A family practice where callers are often frightened or in conflict with a partner should have a person answer first. An AI can catch overflow when every line is busy, but it shouldn't be the first voice someone in crisis hears.

A criminal-defence practice that takes calls at night from people in custody needs a human service with live transfers around the clock. An AI can take non-urgent daytime enquiries, but the night line is the one place a mistake can't be recovered.

Ten scripted calls to test any provider

Before you sign, ring the service yourself, or use the test calls a vendor offers (Smith.ai lists 25 test calls and 50 simulated calls a month on its free AI plan). Keep a score sheet with the ten calls below and a pass condition for each.

1. A routine booking request for a will review. Pass: name, number read back, matter type and a callback time captured in under three minutes.
2. A caller who tells the whole story unprompted. Pass: the handler steers back to the six questions without sounding rude.
3. "Do I have a case?" Pass: declines to assess it and offers a consultation.
4. "How much will it cost?" Pass: quotes only the published consultation fee, or says a lawyer will confirm fees.
5. A caller who says they are frightened for their safety. Pass: urgent route triggered, and the caller is told to contact emergency services if in danger.
6. A caller who names the other side. Pass: spelling captured, no comment on whether the firm acts for anyone.
7. An existing client asking for an update. Pass: message taken and routed to the right lawyer, no matter details given out.
8. A caller with an unusual surname on a poor line. Pass: spelling and phone number read back and corrected.
9. A sales call. Pass: ended politely and not logged as an enquiry.
10. "Am I talking to a robot?" Pass: an honest answer.

Score each call out of ten for accuracy, tone and following the rules, and do not move live until the two crisis-related calls pass. Repeat a shorter version after any change to the script, the provider's settings or your phone setup.

Measuring whether it worked after a month

Choose the measures and targets before the trial starts, so the results can't be argued after the event.

• Answer rate: calls answered by a person or the AI as a share of all calls, from the phone provider's log.
• Enquiry-to-consultation rate for calls the service took, compared with calls the firm answered itself.
• Time from an urgent call to a lawyer's response, from the log you keep.
• Transcript corrections: how many of the transcripts you read needed fixing, and what kind of error it was.
• Caller feedback: any complaint about tone, delay or having to repeat details.

If the answer rate has risen and urgent response times are inside target, the service is earning its cost. If the corrections list shows the same error repeatedly, fix the script first. Only change provider when script fixes stop helping.

Questions lawyers ask before choosing a receptionist

Is an answering service cheaper than hiring a receptionist?

At small volumes, yes. On published plans, 90 calls a month cost $810 through a per-call service, against about $4,333 for an illustrative full-time hire, and the service covers all 168 hours of the week. The hire earns its place when you also need someone for visitors, post and documents, not for calls alone.

Can an AI receptionist run a conflict check?

It can collect the names a conflict check needs, but the check itself, and any judgement about a conflict, belongs to your lawyers. Tell the AI never to confirm or deny whether the firm acts for anyone, and to say only that a routine check happens before every consultation. Review a sample of transcripts weekly to confirm it follows that rule.

Do callers need to be told that calls are recorded or automated?

Say so in the greeting, in one sentence, whichever kind of receptionist you use. Rules on recording consent and on disclosing automation differ between jurisdictions, so check yours with whoever advises the firm on professional conduct, and keep the wording identical across every provider and phone line.

How do I count my calls before choosing a plan?

Export three months of call logs from your phone provider and count calls per month, split by office hours and after hours, plus missed calls and average length. Use the busiest month to size a plan and the quietest to test an AI free tier. If the log doesn't show missed calls, ask the provider for a report.

What if the service can't reach the on-call lawyer?

Agree the sequence in writing before go-live: a live transfer, then a text and email, then a second named contact after a fixed number of minutes, then a final fallback such as a managing partner. Log every urgent call with its times, so you can see exactly where a handover slowed down.
