How to choose an AI answering service: the checklist before you card it

Tuesday at 11:40 a.m. you have three tabs open: a logo grid, a pricing page with a green “from” number, and a calendar invite for a demo. You have not written down the one call that costs money when nobody picks up. The demo will sell features. Your invoice will bill whatever unit you never asked about.

The trap is shopping answers before you write the question. Owners compare brands and floors. The leak is still the ring that dies while you are on a roof, mid-adjust, or stuck on a billing hold. Cash floors and shape guides already live elsewhere. This page is the checklist you fill before any card hits the form.

Sibling depth if you need it later: AI answering service pricing, AI receptionist vs live answering service, month-to-month AI receptionist. Shop the aisle at AI receptionists.

Write the one call that dies when unanswered

Not “all our calls.” One scripted scene on one page.

Emergency after hours: burst pipe, no heat, wet ceiling, roadside tow. FAQ and hours: are you open, do you serve my zip, what do you charge for a tune-up. New patient or new matter: first contact that needs judgment, not a FAQ tree.

If the money call is a 2 a.m. emergency that needs a person on the line, a $49 night bot that texts a booking link is the wrong product. If the money call is lunch overflow asking for a link, a live floor at $250 a month for 50 minutes is the wrong meter. Match product to the call that actually leaves, not to the prettiest logo.

After-hours home-service patterns and the five-minute clock sit in after-hours call coverage for home service and speed to lead: first five minutes. Read them after you write your one call.

Pick the shape before you pick the brand

Three shapes. One decision. Do not redo the full compare here.

1. AI-only: a model greets, runs your FAQ, texts a summary or booking link. No staffed human behind it.
2. Live floor: a person answers every ring you buy.
3. Hybrid: AI first, human on transfer or on the hard buckets.

If you need a person at first contact, skip AI-only demos. If after-hours is mostly “are you open,” skip buying a live desk for FAQ. Shape first. Logo second. Full walkthrough: AI vs live vs hybrid.

A phone system with a small AI pack is not an answering service. OpenPhone (Quo) starts at $19 a user a month with shared SMS and a named AI receptionist on credit packs. Fine as the line. Not the same buy as a dedicated answering plan.

Demand this in writing before you card it

Print this. Ask it on the demo. Screenshot the answer.

1. Included unit. Minutes, calls, or unique callers. Rosie sells minutes (Professional $49 for 250). Goodcall sells unique callers (Starter $79 for 100, then $0.50 each). Smith.ai AI Pro is $150 for 75 calls. Same aisle. Different meters.
2. Overage. What happens when you blow the bucket. Frontdesk Business-in-a-Box is $99 a month for 200 voice minutes, then $0.25 a minute (Frontdesk). Do not treat the annual $79 display as monthly cash. Rosie rounds minutes up and can auto-upgrade the plan. Ruby help-center overage on the starter plan is $5.40 a minute. AnswerConnect Entry overage is $2.50 a minute.
3. Hold and wrap. Live desks often bill hold time and wrap after hangup inside the minute. Ask whether dead air counts. Ruby does. That is how a quiet quote becomes a loud invoice.
4. Cancel notice and minimum term. Marketing “cancel anytime” is not the contract. AnswerConnect terms carry a 90-day floor. Smith.ai cancel is email with 30 days’ notice on our card. Rosie cancels in the dashboard at cycle end. Read month-to-month cancel traps before you trust the hero banner.
5. Warm transfer. Can the product put a live person (yours or theirs) on the line when the script hits a refuse bucket. Rosie warm transfer starts at Scale $149. Goodcall transfers to your people, not a staffed backup. Smith.ai sells live-agent transfers on AI plans.
6. Calendar booking vs link. Pickup that texts a link is not the same as booking your calendar during the call. Rosie Professional texts a link. Calendar booking starts Scale $149. Ask which one you are buying.
7. Bilingual if you need it. English and Spanish on every Rosie plan. Confirm languages in writing for any other vendor before you move the public number.
8. Who owns the number. Vendor-issued numbers you put on Google and the truck are a trap if you leave. Port rules and retention windows matter. Do not publish a vendor number as your brand until you have lived with it and know the exit.
9. CRM / Jobber / Housecall Pro handoff. Native connector, Zapier claim, or “we email you a summary” are three different products. Demand a demo into the system you already open. SEO and marketing agencies that send leads into a dead line are helpers on the same owner. Fix the phone catch so their traffic stops rotting.

Cash floors above match live Counter & Crew tool cards as of this draft (2026-10-01). Dollars move. Check the cards again before you buy. Full cash walk: AI answering service pricing. Side-by-side: /compare/.

Walk away from the demo when

Hang up (politely) when any of these show up:

• They will not put the unit, overage, and cancel rule in writing before a card.
• The money call needs a person and they only sell AI-only.
• They sell “unlimited” without defining the meter (minutes vs uniques vs Fair Use).
• Booking means “we text a link” and you needed the appointment on the calendar during the call.
• They want the brand number on day one with no port or retention story.
• The CRM handoff is a slide. Not a live screen share into Jobber, Housecall Pro, Clio, or whatever you actually run.

Cheap AI floors for FAQ overflow: Rosie Professional $49, Goodcall Starter $79, Frontdesk Business-in-a-Box $99. Hybrid door: Smith.ai AI Pro $150 / human Starter $300. Live floors: Ruby from $250 for 50 minutes, AnswerConnect Entry $350 for 200 minutes. Growth and Scale tiers exist above those. Read the review, not the brochure: Rosie, Goodcall, Frontdesk, Smith.ai, Ruby, AnswerConnect.

The seven decisions, then shop

One page. Fill it before any login.

1. The one call that costs money when it dies (write the scene).
2. Shape: AI-only, hybrid, or live.
3. Unit you will buy (minutes, calls, or unique callers) and an honest monthly count.
4. Overage and hold/wrap rule in writing.
5. Cancel notice and any minimum term in writing.
6. Warm transfer and booking type (link vs calendar) you actually need.
7. Number ownership and CRM handoff you already run.

Then open the aisle, not a random ad: AI receptionists. Compare shortlists on /compare/. If you would rather not become the software person, book a fit call or see nationwide installs. We wire the path the caller actually takes, once, and leave.

FAQ

What should I ask an AI answering service before I buy?

Ask for the included unit, overage, hold/wrap billing, cancel notice, minimum term, warm transfer, booking type, who owns the number, and CRM handoff in writing. Do not card a logo demo that will not answer those nine points.

Is the cheapest AI answering plan enough?

Only if your money call is FAQ and overflow, and you will stay inside the meter. Rosie at $49 and Goodcall at $79 fit that lane. Emergencies and judgment calls need hybrid or live (Smith.ai, Ruby, AnswerConnect), not the cheapest bot.
