The short answer
Cactus is an AI voice receptionist built specifically for home-service trades. It answers 24/7 in English and Spanish, qualifies the caller, and books the job into Housecall Pro or Jobber. It carries a 3x-or-free guarantee, does outbound follow-up calls too, and onboards in 48 to 72 hours. The catch: it does not publish a public price. You get a quote on a demo.
Smith.ai is the more established name. Its AI receptionist answers in English and Spanish and books into Housecall Pro, and its bigger differentiator is an optional human backup that can take over a call the AI cannot handle. It publishes a per-call price, so you can model the cost before you sign.
For a trades shop, the decision is not "which is better software" in the abstract. It is which one matches your CRM, your call mix, and whether a performance guarantee or a human safety net carries more weight for you. Both are real options. They lean in different directions.
What each one actually is
Cactus (built for the trades)
Cactus answers with a natural voice, runs the intake questions a dispatcher would run, and books the appointment straight into your scheduling system. It integrates with Housecall Pro and Jobber, the two CRMs a large share of contractors already run, so a booked job lands in your calendar without anyone retyping it. It answers in English and Spanish out of the box, covers nights and weekends, and will also place outbound follow-up calls. The 3x-or-free guarantee means if it does not return three times the monthly fee in new revenue, that month is free. It does not integrate with ServiceTitan, and it does not list a public price, so you confirm the number on a demo.
Smith.ai (AI plus human backup)
Smith.ai has been in the receptionist business longer than most of the AI-native tools and has the more mature brand behind it. Its AI receptionist answers in English and Spanish, qualifies callers, and integrates with Housecall Pro. The feature that sets it apart is the optional human layer: when a call needs a person, a trained agent can step in. Pricing is published and runs per call, with the AI receptionist starting around $95 a month for 50 calls, so a light-volume shop can predict the bill before committing.
Strip away the marketing and two facts decide most of these calls. Cactus adds Jobber and a revenue guarantee but hides its price behind a demo. Smith.ai publishes its price and adds a human backstop but does not carry a performance guarantee. Everything else, the English-and-Spanish answering and the Housecall Pro booking, both do.
Head to head, point by point
Here is the side-by-side on the things that actually change your revenue and your bill, not the feature-list filler.
| On the call | Smith.ai (AI + human backup) | Cactus (trade-focused AI) |
|---|---|---|
| How it answers | AI voice, human can take over | AI voice, first ring, many calls at once |
| Built for the trades | General business focus | Purpose-built for home services |
| Books into Housecall Pro | Yes | Yes |
| Books into Jobber | Not a stated integration | Yes |
| Bilingual English + Spanish | Yes | Yes |
| Human backup on hard calls | Yes, optional human layer | AI only |
| Performance guarantee | None published | 3x-or-free |
| Outbound follow-up calls | Varies by plan | Yes |
| Pricing | Published, per call from ~$95/mo | Demo-quoted flat fee |
| Time to launch | Days, self-serve setup | 48 to 72 hours, done for you |
The honest read: Smith.ai wins on the human backstop and on price transparency. Cactus wins on trade fit, the Jobber integration, the guarantee, and the hands-on onboarding. Neither one is strictly ahead. They are ahead on different things.
Pricing: per-call vs demo-quoted flat
The two are priced on different logic, and that shapes who each one suits.
Smith.ai bills per call. The AI receptionist starts around $95 a month for 50 calls (per provider, as of mid-2026, confirm current pricing with the provider). That is predictable when your volume is steady and light, and it climbs as calls stack up, so a busy season costs more. The upside is you can put a real number in a spreadsheet before you sign anything.
Cactus quotes a flat monthly fee on a demo. There is no public price, which is the friction point: you have to take the call to learn the number. Once quoted, a flat fee holds steady even when a heat wave triples your call count, and the 3x-or-free guarantee puts the provider on the hook for results rather than just uptime.
| Provider | Model | Entry price | Notes |
|---|---|---|---|
| Smith.ai (AI) | Per call | From ~$95/mo (50 calls) | Published; human backup optional; Housecall Pro |
| Cactus | Demo-quoted flat | Quoted on a demo | Trade-built; Housecall Pro + Jobber; 3x-or-free |
| Goodcall | Per unique caller | $79, $129, $249/mo | Pure AI, home services, unlimited minutes |
| Ruby / PATLive | Per receptionist minute | ~$250/mo and up | Live humans, usually message-taking not booking |
All figures above are per provider, as of mid-2026, and directional for the third-party services. Confirm current pricing with each provider before you buy, because published tiers move. The point of the table is the model, not a to-the-dollar quote: Smith.ai lets you predict a light month, Cactus lets you cap a heavy one.

Get matchedThe human backup question
This is Smith.ai's strongest card, so it deserves a straight look. A pure-AI receptionist is very good at routine intake: what is broken, where are you, when can we come out. It is weaker when a call turns emotional, gets legally sensitive, or veers far off any script it was trained on. Smith.ai can route those calls to a trained human, which is a real safety net.
How much that matters depends on your call mix. If you run a lot of delicate, non-standard conversations, the human layer earns its keep. If your inbound is mostly no-heat, no-water, and no-AC calls that need fast qualifying and a booked slot, the AI handles the volume and the human backstop matters less. Cactus goes the other way: no human layer, but a guarantee that ties the provider's pay to booked revenue. One de-risks the hard call. The other de-risks the outcome.
Bilingual coverage and CRM booking
Two things a lot of trades shops treat as non-negotiable, and here the providers are closer than the marketing suggests. Both Cactus and Smith.ai answer in English and Spanish, which matters in markets where a real share of inbound comes in Spanish and a missed Spanish call goes straight to the next contractor. If bilingual is a hard requirement, either one clears it.
CRM booking is where the daylight opens up. Both book into Housecall Pro, so if that is your system, either works. Cactus also books into Jobber, and it does not integrate with ServiceTitan. Smith.ai's stated fit is Housecall Pro. So the CRM you already run can settle the whole decision: on Jobber, Cactus is the one that books directly into your calendar; on Housecall Pro, both qualify and you weigh the guarantee against the human backup.
I run paid and organic lead gen for home-service shops, so I care about one number: did the call turn into a booked job. When a real buyer with a dead furnace hits voicemail, the ad dollar that generated that call is gone. Between these two, I tell a Jobber shop to look hard at Cactus, because booking into the CRM you already run beats a callback every time, and the guarantee means somebody other than you is on the hook for the result. I tell a Housecall Pro shop that runs a lot of touchy calls to weigh Smith.ai's human backstop seriously. The wrong move is picking on brand name alone. Pick on CRM and call mix.
Lean Cactus when
- You run Jobber, or Housecall Pro, and want direct booking
- Bilingual English and Spanish is a must
- You want a performance guarantee, not just uptime
- You want it live fast, done for you in 48 to 72 hours
- Outbound follow-up calls are part of the job
Lean Smith.ai when
- You want a human to catch the hard, off-script calls
- You want a published price you can model up front
- Your call volume is light and steady
- Housecall Pro is your system and Jobber is not in play
- Brand maturity carries weight in your decision
Why speed-to-lead sits under both
The best-documented finding in lead response: firms that contact a new online lead within five minutes are far more likely to reach and qualify that person than firms that wait, and the odds fall off sharply after that (Harvard Business Review, "The Short Life of Online Sales Leads," 2011). A contractor who returns a voicemail two hours later, after finishing a job, has usually already lost the customer to whoever answered first.
This is the reason to run either one rather than neither. Both Cactus and Smith.ai answer instantly on the AI layer, which is the only reliable way to win that five-minute window on every call. Home-service callers rarely leave a voicemail. A missed call goes to the next company on the list. The choice between these two providers is a refinement. The choice to answer at all is the one that moves your revenue.
There is a money angle underneath it. You already pay for Google Ads, Local Services Ads, SEO, and lead marketplaces to make the phone ring. A missed call wastes the ad dollars that generated it. Either provider protects spend you already committed, which reframes the fee from a new expense into cost recovery. Run the numbers on your own missed calls with the revenue calculator.
The trades pick, and why
Generic AI receptionists answer any business. The trades have specifics: dispatch logic, service-area questions, emergency triage, and the fact that so much revenue rides on booking the job while the caller is still on the line. Both providers here can do trades work. One was built for it.
Among these two, we give the trades pick to Cactus when the fit lines up: it is built for home services, it books into Housecall Pro and Jobber, it answers in English and Spanish, and it carries a 3x-or-free guarantee that ties the provider's pay to booked revenue. That is not a knock on Smith.ai, which is the right call when you specifically want a human backstop on hard calls and a published per-call price. Cactus earns the trades pick on those merits, the CRM fit, the bilingual coverage, and the guarantee, not because this site is referral-supported.
The verdict for a contractor
Pick Cactus if you are a trades shop that wants bilingual booking into Housecall Pro or Jobber plus a performance guarantee, and you can live with getting the price on a demo. Pick Smith.ai if you specifically want a human backstop on the calls the AI cannot handle and a published per-call price you can model before you sign. Both answer instantly, both speak Spanish, and both book into Housecall Pro, so you are choosing between a guarantee-and-Jobber shop and a human-backup-and-transparency shop. Match it to your CRM and your call mix, and the answer usually names itself.
