About this list
Plumbers lose work in small ways. A call goes to voicemail while you're under a sink. A quote never gets a follow-up. A bill sits unpaid for weeks. Each tool on this page takes one of those jobs off your plate. The list is in order by job, not by score.
Answering calls and texts: Avoca AI Front Office answers every call day and night and books the job. Avoca's case study says HL Bowman, a Pennsylvania HVAC and plumbing company, cut its cost per new customer from $350 to $215. That is the maker's number, not our test. Front Desk Text Drafter writes a reply to each customer text, and you OK it before it sends. Floods and gas smells go straight to you.
Follow-up: Plumber Follow-Up Bot follows up on quotes, reminds customers before a job, and nudges people who haven't paid. A plumber on Reddit's r/Plumbing said this kind of setup saves 6 to 8 hours a week.
Office help: Claude-Built Zaps comes from 3R Plumbing & Mechanical, which uses Claude to build its Zapier automations. One keeps a call-back list of missed calls and open quotes, updated every 15 minutes. Another emails a morning brief at 6:30 a.m. AI Invoice Review checks each job's invoice before it goes out. It's a ServiceTitan feature that was in beta.
Running the business: Jobber, Housecall Pro, Workiz and ServiceTitan are full field-service apps for quotes, scheduling, dispatch and billing. See Jobber vs Housecall Pro vs ServiceTitan or Jobber alternatives.
Some tools are ready-made apps you sign up for. Others are setups you build yourself with tools like Zapier, Google Sheets or an AI helper. The Setup column tells you which. Not sure missed calls cost you much? Try the missed-call cost calculator.

Price: from the maker’s pricing page when the row links one (read Oct 25–26, 2026), otherwise from our listing for that tool. “See site” means we did not find a clear price. What it does, setup and hours come from our listing and its source. “est.” and “Our estimate” mean our guess from similar tools, not a measured number; maker claims are labeled. The directory is free to search; the tools are made and priced by each maker, and prices change often. None of these links pay us.

Questions people ask
How can a plumber use AI?
Most plumbers start with one job: answering calls, replying to texts, or following up on quotes. Pick the one that loses you the most work and try a tool for that first.
Is there an AI receptionist for plumbers?
Yes. Avoca AI Front Office answers calls and books jobs for HVAC and plumbing shops. Its listing shows no price, so check its site. For more options, see our AI receptionist list.
How much do AI tools for plumbers cost?
Jobber's pricing page shows Core from $29/mo billed yearly, or $49/mo with no commitment. Housecall Pro's Basic plan is $59/mo billed yearly. Workiz, ServiceTitan and Avoca don't show a clear price on our listings. The do-it-yourself setups need paid apps like Zapier or a texting service. The directory is free to search. The tools themselves are made and priced by each maker.
Do I need to know how to code?
No for ready-made apps like Jobber, Housecall Pro and Avoca. The do-it-yourself setups (Plumber Follow-Up Bot, Front Desk Text Drafter, Claude-Built Zaps) take some setup, but each page has the steps in plain words.
Is it OK to text customers automatically?
Texting rules depend on where you work. Check the texting and consent rules for your area before you turn on automatic texts.
How does BusyWorkBots pick these?
Every listing links to a real source, a case study, a builder's post, or the maker's page. Numbers from the company selling the tool are labeled as a maker or vendor claim. We don't test every tool.
