For calls, a built-in agent such as Jobber's Receptionist or Housecall Pro's CSR AI, or a standalone one such as Smith.ai, suits small trades firms. For texts, use a missed-call auto-reply or the built-in agent. For website chat, a free or low-cost chat tool that hands leads to you is enough. A support-desk suite is more than you need.
Each channel needs something different. A call needs booking rules and an escalation phone; a text needs a registered number and short messages; a chat needs a hand-off to you and a rule against quoting prices. Plan limits matter just as much: Jobber counts conversations, Tidio's free plan gives 50 AI conversations in total, and Botpress's free plan stops at 100 a month.
What each channel needs from you before a tool can help
A trades business gets customers on three channels, in descending order of urgency. The phone is where emergencies arrive, texts are where people send addresses and photos, and website chat catches the visitor who would rather not ring. No tool can fix a channel you haven't prepared.
| Channel | What the customer wants | What the tool needs from you | What typically goes wrong |
|---|---|---|---|
| Calls | An answer now, a booked visit, or a person if it is urgent | A number the agent can answer, booking rules, an escalation phone that differs from the main line | Invented prices, wrong transfers, no plan for an unanswered hand-off |
| Texts | A quick reply, a time or a link; may answer hours later | A number that can send business texts, short plain wording, a person who can take over | Landline callers never get the text; long messages are split; customers expect a human reply |
| Website chat | An answer without making a phone call, often late in the evening on a phone | A short list of questions, a way to send leads to you, a no-prices rule | Leads sitting unread; the plan's cap reached mid-month; the bot answering beyond what you told it |
Notice that none of the failure modes is about how clever the AI is. They are about the owner's set-up, which is why the sections below spend as much time on limits and wording as on features.
Calls: a built-in agent or a standalone one?
Job-software agents have one big advantage: the booking lands in the calendar you already use. Standalone products win when you don't use job software, or when theirs doesn't offer an agent. As of October 2026 these are the published details, taken from each vendor's own pages.
| Tool | Price as published | Texts and chat | A limit to know |
|---|---|---|---|
| Jobber Receptionist | $29 a month add-on with 30 conversations, then $0.79 each; unlimited on the Plus plan | Answers calls and texts; can text back callers who hang up; the product page doesn't mention web chat | Needs a dedicated number even when you forward; online booking must be on for rescheduling |
| Housecall Pro CSR AI | 24/7 call answering is a paid feature; no price on its pages | Chat is included on all plans; texts are listed as coming soon | If it can't book a job it notifies you and you call back |
| Workiz Genius Answering | No price on its page | Answers calls, emails, texts and web forms; the page doesn't mention web chat | Its FAQ limits live transfers to business hours |
| Smith.ai AI Receptionist | Free for 25 calls, then $3 a call; Pro $150, $270 or $500 for 75, 150 or 300 calls, with extra calls at $2.50, $2.30 or $2.17 | Phone answering; Pro lists custom SMS branding, but the page describes no two-way texting | Every answered call counts; calls from known spammers don't |
| Quo (business phone) with its Sona agent | Seats $15, $23 and $35 a month billed annually ($19, $33, $47 monthly); Sona from $0 for 10 calls, then $25 for 40 calls | Texting and auto-replies on every plan; Sona answers calls | Call transfers aren't on the Starter plan |
One detail in that table is worth a second look. Housecall Pro's FAQ puts its chat agent on every plan and treats round-the-clock call answering as the paid part, which is worth knowing if chat is the channel you care about. Jobber's help article, updated on 28 October 2026, says a call counts towards the allowance only when the agent actively engages with the caller, and that spam doesn't count. If you would rather have a person on every call, Smith.ai's human receptionist plans show the size of the gap: $300 for 30 calls, $810 for 90 or $2,100 for 300, with extra calls at $11.50, $10.50 or $8.50 each. For how the transfers and keywords work in each, the tutorial on built-in against standalone AI receptionists for trades goes further, and so does the one on which Workiz Genius add-ons are worth it.
Texts: missed-call text-back and two-way replies
Text-back has two forms, and they behave differently. The first is a fixed auto-reply: Quo's page describes auto-replies that answer "texts, missed calls, or voicemails with pre-defined messages", on every plan. That is reliable because you wrote every word, and limited for the same reason. The second is an agent that writes its own replies. Jobber's page says its Receptionist answers texts and can text back callers who hang up, and that you can watch text conversations live and take over. Workiz's page lists texts among what its agent answers and says it can follow up on unanswered messages; its FAQ includes a question about stopping it from answering emails and texts during business hours.
The limits are mostly practical. Housecall Pro lists text answering as coming soon. Jobber's page describes booking "during the call", so booking by text isn't explicit. A text-back to a landline never arrives, so it can't be your only response to a missed call. Quo's page lists a one-time carrier registration fee of $19.50 for business texting and a monthly messaging fee of $1.50 to $3, which is a reminder that sending texts at all can involve registration and fees whichever tool you pick. Some carriers split a message longer than 160 characters, and an emoji or a curly apostrophe can cut that to 70, so keep text-back wording short and plain. Consent rules for texting differ from place to place, and your adviser should tell you what applies and how an opt-out should work. The tutorial on setting up missed-call text back for a service business covers the set-up steps.
Website chat: the limits that decide the cost
With chat, the plan limit is the whole story, because a chat widget that stops answering mid-month is worse than none. These are the entry-level limits on the pages I read.
| Tool | Entry price | What is counted | At the limit |
|---|---|---|---|
| Housecall Pro CSR AI chat | Included on all plans, per its FAQ | Not stated | Not stated |
| Tidio with Lyro AI | Free plan, with the first 50 AI conversations free in total; the standalone AI agent starts at $32.50 a month for 50 conversations | Conversations; Starter at $24.17 a month includes 100 billable conversations | Higher quotas sit on its Plus and Premium plans; removing Tidio branding is a $16.67 add-on on the Growth plan. The page has a monthly or annual toggle and doesn't label which rate these figures are, so check before you budget |
| Botpress | Free plan with 100 conversations a month; Plus at $150 a month billed annually with 250 | Conversations | Free is hard-capped with no top-ups; Plus buys 100-conversation packs ($65 each) automatically at 95% of the allowance |
| Chatbase | No free plan; Hobby is $32 a month billed yearly for 700 message credits, with a 7-day trial | Message credits | The page doesn't say; it describes optional auto-recharge at $40 per 1,000 credits |
Two points follow. The "free" chat plan that lasts for ever doesn't exist here: Tidio's 50 free AI conversations are a lifetime allowance, so a firm with 20 chats a month spends it in under three months and then pays. And the build-your-own tools, Botpress and Chatbase, suit an owner who enjoys tinkering. For most trades firms the simplest route is a chat that is already part of the software they use, or a short hosted widget with a fixed list of questions. How the options differ for a roofing company in storm season is in the tutorial comparing roofing chatbot platforms.
Why support-desk lists suit teams, not a small trades firm
Search for AI customer service tools and the lists you find compare helpdesks built for support teams. They assume agents with seats, a ticket queue and an onboarding project. HubSpot's Service Hub Professional, for example, lists at $90 a seat a month on annual billing ($100 monthly) plus a $1,500 onboarding fee. Intercom's Fin charges $0.99 per outcome, where an outcome can be a resolved question or a completed workflow, including a hand-off. Those prices make sense for a team answering hundreds of tickets a day.
A trades firm is the opposite case. It has one office person or the owner, enquiries that need a job, a visit or a quote at the end, and a phone as the main channel. The test for any tool in this category is simple: does the enquiry end up in your job software as a request, a job or a task? If it ends up in a separate inbox, you have bought a second place to look.
A five-person plumbing firm's month: 60 calls, 25 texts, 15 chats
Here is an invented but plausible month for a five-person plumbing firm. The agent engages with 60 callers, 25 customers text back or text in, and 15 visitors use the website chat. Three builds follow, priced from the published figures above.
| Build | Calls and texts | Chat | Monthly total |
|---|---|---|---|
| A. On Jobber: Receptionist add-on | 60 calls plus 25 text conversations is 85 conversations: $29 plus 55 at $0.79 is $72.45 | Tidio free for about three months, then $32.50 | $72.45, then about $105 once the free chat allowance is spent |
| B. Quo: two Business seats at $23 and Sona | Seats $46; Sona for 60 calls is $25 plus 20 extra at $0.75, so $40; auto-replies cover texts; plus a messaging fee of $1.50 to $3 | Same Tidio route | About $87 to $89, then about $120 |
| C. Smith.ai AI plus separate texting and chat | Free plan: 25 calls included, then 35 at $3, so $105; the $150 Pro plan (75 calls) adds onboarding and an account manager | Same Tidio route | $105, then about $138, with no two-way texting included |
The ranking changes with volume. Double the traffic to 120 calls and 40 text conversations and Build A becomes $29 plus 130 at $0.79, which is $131.70, while Build B's Sona cost is $49 plus 20 extra at $0.65, so $62, plus $46 in seats for $108. Smith.ai's 75-call Pro plan would be $150 plus 45 extra at $2.50, or $262.50, just under the $270 of its 150-call tier and below the $285 the free plan would charge. So Jobber's add-on is cheapest at low volume if you already use Jobber, the phone-system route overtakes it as calls grow, and the agent that bills per call becomes the most expensive of the three. Housecall Pro and Workiz don't publish a price for their call agents, so the honest line in a comparison like this is a question mark, and the right move is to ask for a written quote at your volume.
One build changes if the firm is already on Housecall Pro: chat is included on every plan, so only the 24/7 call answering is an add-on, and the sum becomes "what does Housecall Pro charge for it?" rather than a comparison of vendors.
Missed-call text wording that works, and one that doesn't
For an electrical contractor, the text a missed caller receives is the first message the firm ever sends them. This version is plain, short and promises nothing the firm can't keep:
Hi, this is [business name]. Sorry we missed your call. Reply with your
address and what's wrong and we'll reply today. Emergency? Call [number].Compare the version an eager owner writes at 11 pm:
Thanks for calling! We'll be with you in 15 minutes! Prices start at $49,
no hidden fees!!The second message promises an arrival time that the firm can't guarantee at night, quotes a price for a job nobody has described, and invites an argument about "hidden fees" before the first visit. It is also long enough, with punctuation, to risk splitting on some carriers. A useful habit is to read every automated message as if a customer will screenshot it for a complaint, because some will. If your product lets you set different text-back messages for open and closed hours, use that: during hours, "we'll reply shortly"; after hours, "we'll reply when we open at [time]".
Chat rules for a roofing company in storm season
A roofing company's chat will be asked three things after a hailstorm: can you give me a price, will insurance pay, and can someone come today. The rules should answer none of them with a promise. An invented exchange, with what I'd change in it:
Visitor: Hail damaged my roof. Can you give me a price?
Chat: I can book an inspection so someone can look properly. What's your
address, and is any water coming in right now?
Visitor: A bit in the hallway.
Chat: Thanks. Active leaks go to our office team straight away. Can I take
your name and phone number so they can call you? If anyone is at
risk, please call the emergency services.That exchange is close to right. The chat doesn't quote a price, it asks about an active leak before anything else, and it hands over to a person. I would still change two things. It shouldn't say "straight away" unless someone will genuinely call back quickly, and it should have a firm line on insurance: "I can't advise on claims, but the office can explain what we document". Chats that wander into claims advice create liability for the firm.
A cleaning company's chat intake, field by field
A cleaning company shows the other side of chat: not emergencies, but a quote that depends on six facts. Compare the standard contact form, which asks for a name, email and "message", with a chat that collects the facts a person needs to price the job.
- Type of clean: regular, one-off deep clean, end of tenancy or after building work.
- Size of the home: bedrooms and bathrooms.
- Frequency: weekly, fortnightly, monthly or once.
- Pets and anything the cleaners should know on arrival.
- Access: someone at home, a key safe or a code.
- Preferred days and a phone number, so someone can confirm.
The chat should give no price. Its job is to turn "how much for a clean?" into a request a person can quote in a minute, which is the same logic as the tutorial on choosing between an AI receptionist and a chatbot for a cleaning company. If a visitor refuses to answer the size question, the fallback is to take a phone number and stop, not to guess.
Test messages to send before go-live
Test every channel the way a customer would, from a phone and a browser the system doesn't know. Calls have their own routine in the 15-call test for plumbers; these are the checks for texts and chat.
- Ring your business number from a mobile and hang up. Does a text arrive within a minute, and is the wording what you wrote?
- Reply to that text with an address and a problem. Does a person or the agent answer, and does a request appear in your job software?
- Reply "STOP". Does the messaging stop, and can you see that the customer opted out?
- Open the website chat and ask for a price. It should decline politely and offer a visit or a call-back.
- Type "water coming through the ceiling". It should ask whether anyone is at risk and hand over to a person.
- Ask for something you don't do, such as a swimming pool. It should say so or hand over, not invent an answer.
- Complete the chat with a phone number. Does the lead reach your job software or inbox within a minute?
Write down each result. The failures cluster in the same places every time: a message that goes nowhere, an answer given outside what you told the tool, and a lead that lands in an inbox nobody opens.
A first-month scorecard for calls, texts and chat
Each channel needs three numbers, and the products differ in how easily they give them to you. Jobber logs every call and text with a short summary, a full transcript and, for calls, a recording. Housecall Pro's call details show the customer's information, a summary and the urgency of the call. Where a vendor's page doesn't say what reporting you get, ask before you rely on it.
| Channel | Count these | What a poor result tells you |
|---|---|---|
| Calls | Conversations the agent had, bookings made, transfers, messages, callers who hung up first | Many hang-ups mean the opening line or the price answer is putting callers off |
| Texts | Text-backs sent, replies received, replies that became a request or a visit | Almost no replies means the wording is wrong, or many callers are on landlines |
| Chat | Chats started, chats that left a phone number, leads that became a visit | Plenty of chats but few numbers means the questions come before the value, so ask for the number earlier |
Read the transcripts as well as the totals. A booking count can look healthy while the agent is quietly promising times you can't keep, and only the text of the conversations shows that.
Choosing by channel: a one-page decision
| If you already use | Calls and texts | Chat |
|---|---|---|
| Jobber | Receptionist add-on; it answers calls and texts, so watch the conversation count | Ask Jobber whether Receptionist can answer chat on your website; its product page doesn't say |
| Housecall Pro | CSR AI 24/7 call answering; ask for the price in writing, and don't count on texts yet | CSR AI chat is included on every plan |
| Workiz | Genius Answering; ask what it costs and whether business-hours-only transfers suit you | Its page doesn't mention chat; use a separate widget |
| None of these | A business phone such as Quo for texts and auto-replies, plus Sona or a standalone agent such as Smith.ai for calls | A short widget such as Tidio, with five fixed questions and a hand-off to you |
Whichever column you land in, run the same two checks before paying. First, put your real month's volume through the sum, because the cheapest option at 60 calls is not the cheapest at 120. Second, send yourself a missed-call text, a chat message and a call, and read the three records that arrive in your job software. If any of them lands somewhere you wouldn't look, fix that before anything else.
Questions trades owners ask about AI customer service tools
Do I need a different tool for calls, texts and chat?
Not always. Jobber's Receptionist covers calls and texts, Workiz's Genius Answering lists calls, emails, texts and web forms, and Housecall Pro's CSR AI covers calls and chat, with texts listed as coming soon. Website chat is the channel most likely to need a separate tool, so check which channel your current job software leaves out before buying anything.
Can AI text back customers who call and hang up?
In some products, yes. Jobber's page says its Receptionist can text back callers who hang up, and Quo's auto-replies respond to texts, missed calls or voicemails with predefined messages. Landline callers can't receive texts, so a text-back never replaces answering the call, and your adviser can tell you what consent and opt-out rules apply where you work.
Is a free website chatbot good enough for a plumber?
It can be, if the job is narrow: collect the problem, address and phone number, answer five fixed questions and pass emergencies to you. Check the cap first. Tidio's free plan covers the first 50 AI conversations in total, and Botpress's free plan is hard-capped at 100 conversations a month with no top-ups.
Why not buy a helpdesk such as HubSpot or Intercom?
Those are built for support teams with agents, ticket queues and onboarding projects. HubSpot's Service Hub Professional lists at $90 a seat a month billed annually plus a $1,500 onboarding fee, and Intercom's Fin charges $0.99 per outcome. A three-person trades firm needs the request to land in its job software, not in a queue nobody has time to work.
What happens when I reach the plan's conversation limit?
It varies, so read the page. Jobber lets an admin choose between paying $0.79 for each extra conversation and pausing the agent, and a paused agent takes messages but can't book. Botpress's free plan has no overages, while its paid plans buy 100-conversation packs automatically at 95% of the allowance. Chatbase's page doesn't say what happens at the limit.
