The Flat-Rate Smith.ai Alternative. No Per-Call Fees.

Smith.ai is a virtual receptionist and answering service that pairs AI call answering with North America-based live agents. It answers and screens calls and runs the intake process for law firms, professional services and small businesses. It’s a legitimate, well-run receptionist service — the difference is that Inboxsmith is flat-rate and built only for the home-services trades.

Smith.ai bills per call rather than per minute. Each AI Receptionist plan includes a set number of calls — 50 on the $95/mo Starter plan as of July 2026 — then you pay a charge per call beyond it ($2.40 on their self-serve plans), plus à-la-carte fees for things like booking an appointment (~$1.50/call) or escalating to one of their human agents (~$3/call).

As of July 2026, Smith.ai’s AI Receptionist plans run $95/mo (50 calls), $270/mo (150 calls) and $800/mo (500 calls), with overage billed per call. Their Managed plan — the closest match to a done-for-you service — starts at about $500/mo on a 6-month term for 300+ calls, at their stated ~$1.50 or less per call. Check their site for current pricing.

Not hidden, but à la carte: appointment booking, payment collection, a Spanish line, call recording, and reaching one of Smith.ai’s own human agents are each billed per call on top of your plan. To be fair, transferring a caller to your own crew is included — the per-call charge is for escalating to Smith.ai’s receptionists. Add those extras plus overage and a sticker price can climb well past what you expected.

They’re different pricing structures. Per-call billing charges for every answered call regardless of length — a 30-second wrong number costs the same as a 15-minute intake call. Per-minute billing charges only for the talk time you actually use. Inboxsmith includes about 1,800 minutes per month (approx. 600 calls at average call times), and anything over bills per minute at a flat $0.20 — so short calls barely dent your plan.

Inboxsmith is one flat, done-for-you plan — $397/mo. Your calls are included (~600/mo), and live transfer to your crew, in-call booking, and emergency triage come with it — not as add-ons. That’s roughly twice the calls of Smith.ai’s comparable Managed plan (about $500+/mo for 300+ calls) at a lower price, which works out to about half the cost per call, with no per-call billing.

Overage on Inboxsmith’s plan is a flat $0.20 a minute — never per-call billing, so a 30-second wrong number never costs what a 15-minute intake does. We also size the included ~1,800 minutes so a typical shop won’t hit overage — that’s about 20 three-minute calls a day — and a storm week won’t blow up your bill.

Smith.ai’s AI Receptionist plans come with a 30-day money-back guarantee (up to $1,000, overage excluded) — check their site for any trial offers. Inboxsmith runs a free 7-day pilot on your overflow and after-hours calls — up to 7 days or 300 minutes, whichever comes first. A card on file confirms you’re a real business; you’re never charged during the pilot.

Your call — it’s configured to how you run your shop. Out of the box, Inboxsmith captures the job and offers a time window your office confirms, and it leaves pricing to you. Prefer it to quote your approved price list, or to commit firm appointment times instead of windows? We set that up for you during onboarding. The one thing that never changes: it won’t invent a price or a time it wasn’t given.

No — Inboxsmith is built specifically for home-services contractors: HVAC, Plumbing, Electrical, Roofing, Pest Control and Garage-Door. If you run a law firm or professional-services office, Smith.ai’s legal integrations may suit you better. We’d rather be the best answer for the trades than a generalist.

Yes. We forward your existing business number, so nothing on your trucks, cards or listings changes — and we set it up for you. You can try it first with a free 7-day pilot before you commit.
