For US plumbing and electrical contractors

AI for plumbing and electrical contractors that chases open bids, unpaid invoices, permits and annual test reminders.

Written for owners and office managers of US plumbing and electrical companies with two to thirty field staff, including shops that run both trades. Most of what ranks for this query is a vendor selling an AI phone answering service or a trade article listing what AI might do one day. The question an owner actually has is narrower. Who follows up the panel upgrade bid sent last Thursday, who chases the general contractor at day 60 for a progress payment with retainage, and who reminds the property manager that the backflow test is due before the water utility sends a notice, when the office is already full.

In short

AI for plumbing and electrical contractors pays back on the paperwork around the work, not the work. A briefed agent follows up every open bid and service estimate on a schedule, drafts payment reminders for aged invoices and progress billings, tracks permit and inspection status from your records and flags what is stalled, sends annual backflow, water heater and panel inspection reminders to maintenance customers, assembles utility and EV charger rebate paperwork from job notes, and writes the weekly report of open bids, receivables and expiring licenses. It drafts, you approve, and nothing goes to a customer without your click. WorkAgent does this for a flat $149 a month with no per-user fee.

Housecall Pro: Basic $59 a month billed yearly ($79 monthly) for 1 user; Essentials $149 ($189) for 5 users; Max $299 ($329) for 8 users, extra users $35 a month (vendor site)
Jobber: Core $49 a month for 1 user; Grow $299 a month for 5 users; extra users $29 a month (vendor site, monthly rates)
WorkAgent: $149 / month, flat, no per-user fee

What it handles

What a plumbing or electrical owner actually hands over

The bid follow-up, permit tracking and collections that pile up while the crews are on site, and what a briefed agent takes off an owner's week.

Bid and estimate follow-up

A water heater replacement quote, a 200 amp panel upgrade or a bathroom rough-in bid goes out and then nobody touches it. The agent reads your open estimates, drafts a follow-up at day two, day seven and day fourteen in your voice, mentions the scope and the financing option you quoted, and tells you which customers replied. Most bids that die were never followed up, not rejected.

Progress billing and aged invoices

On commercial and remodel work you wait on general contractors and property managers. The agent keeps a list of what is invoiced, what is past 30, 60 and 90 days, drafts the reminder with the invoice and any lien waiver or retainage note attached, and gives you a short call list of the accounts that need a human.

Permit and inspection tracking

Permits sit with the city or county and nobody owns the follow-up. From your job records and inbox the agent keeps a status list, flags permits with no inspection scheduled, drafts the note to the inspector's office or the customer, and tells you which jobs cannot be invoiced until the final passes.

Annual test and inspection reminders

Backflow preventer tests, water heater flushes, panel and smoke detector checks are recurring revenue that lapses because no one sends the reminder. The agent builds the due list from last year's jobs, drafts the notice 45 days out and flags the customers who ignore it. Many water utilities require an annual backflow test on commercial accounts, so these reminders also keep your customers compliant.

License, insurance and certificate paperwork

Contractor license renewals, continuing education, workers comp and general liability certificates all have dates. The agent keeps the calendar, drafts certificate requests to your insurance agent when a general contractor asks for one, and warns you 60 days before anything expires.

Rebate and incentive packets

Heat pump water heaters, EV charger installs and panel upgrades often qualify for utility or state rebates that need the invoice, model numbers and photos in a set format. The agent assembles the packet from job notes, lists the gaps, and drafts the submission for you to check.

Supplier price checks and the weekly report

It compares a supplier quote against your last three purchases of the same item and flags the jumps, then writes a Friday report of open bids, receivables, permits and expiring documents so you start Monday knowing what to chase.

Why it works

Why plumbing and electrical owners look at an agent rather than another app

The software holds the record, nobody holds the follow-up

Your field service app knows the job, the customer and the invoice. It does not read a stalled permit, remember that the backflow test was due in March or chase a general contractor with the right retainage language. That is a person with a list, and the person is busy.

Seasonal peaks and emergency calls eat the office

A burst pipe or a failed panel pushes everything else back by a day. Follow-up that depends on spare office hours simply does not happen in the weeks that matter most.

You approve what customers see

The agent drafts and prepares. It does not dispatch, take card payments, pull permits or send a message to a customer unless you approve it, so tone and commitments stay yours.

Four ways to get bid follow-up, collections and compliance reminders done

Compared on follow-up and back-office work only. None of these replaces the crews or the dispatcher.

Where the office hours go in a plumbing or electrical company

The revenue sits in a few piles. There are bids waiting for an answer, invoices waiting for a check, permits waiting for an inspection, and annual tests waiting for a reminder. Each pile is worth real money and each needs a small, repeated nudge. The nudges are what get skipped when a crew calls in from a job with a surprise behind the wall.

None of that is skilled trade work. It is reading a list, writing three sentences and sending them at the right time, then noticing who answered. That is the job an agent does without getting tired in January or July.

The arithmetic on one pile

WorkAgent Starter is $149 a month, which is $1,788 a year month to month or $888 billed yearly. A panel upgrade or repipe bid is often several thousand dollars, so one extra job closed from a bid that would have gone cold covers the year. So does one aged progress payment collected a month earlier, or a handful of backflow tests that would have lapsed and been booked by a competitor instead.

Against an office hire the comparison is hours. If you or your office manager spend ten hours a week on follow-up, collections and paperwork, those are the hours to brief the agent with first. Keep the person for the phones and the schedule; move the chasing.

What the agent does not do

It does not answer your phones, dispatch crews, take card payments, pull permits, size a load calculation or give code advice to a customer. It does not replace a licensed person signing off work. It does not contact customers on its own; whatever it drafts goes out under your name only after you approve it.

Where it reads your records depends on where they live. If your jobs are in Housecall Pro, Jobber, ServiceTitan or QuickBooks, the agent works from their exports and from your inbox, calendar and shared drive. If your leads sit in a sales CRM it connects on the Pro plan and works as an AI CRM assistant.

Pricing for a plumbing or electrical company, and how it compares

WorkAgent is $149 a month on Starter, $499 on Pro and $1,299 on Scale, month to month, flat, with no per-user fee. Yearly billing halves that: Starter is $888 for the year. A company with twenty field staff and three in the office pays the same as a two-van shop.

Keep your field service software. At $59 to $299 a month for Housecall Pro or from $49 for Jobber, it holds the schedule, the invoice and the customer, and the agent does not replace that record. What the agent replaces is the follow-up that nobody has time for. If you run HVAC alongside the other trades, the same setup is described on our page about AI for HVAC companies, and the field service software comparison is in HVAC software pricing.

How to brief it for the first month

Start with three jobs: follow-up on every bid older than three days, a reminder sequence on invoices past 30 days, and the list of annual tests and inspections due in the next 60 days. Give the agent your estimates and invoices export, last year's job list and one follow-up message you actually like. Approve everything it drafts in the first two weeks.

Add permit tracking and rebate packets once the first three jobs run without supervision. Owners who hand over everything in week one spend week two correcting tone. Owners who start with bids, invoices and annual reminders usually see money move inside the first month.

FAQ

Questions plumbing and electrical contractors ask

What is the best AI for plumbing and electrical contractors?

It depends on the job. An AI phone answering service is right for catching calls and booking. Field service software is right for scheduling, dispatch and invoicing. For bid follow-up, collections, permit tracking and annual test reminders, an AI agent that works across your exports and inbox does more. Many contractors end up using two of the three.

How can plumbing and electrical companies use AI?

The practical uses are answering calls, following up bids, chasing unpaid invoices, tracking permits and inspections, reminding customers of annual tests, preparing rebate paperwork and writing weekly reports. AI does not diagnose a job or replace a licensed tradesperson. It handles the repeated office tasks that get skipped when crews are busy.

Can AI automate bid and estimate follow-up for contractors?

Yes. An agent reads your open estimates and drafts follow-ups at the intervals you set, mentioning the scope and financing you quoted. You approve the messages, or let a proven routine send on a schedule, and the agent reports which customers replied so you only call the ones who did.

How much does AI for a plumbing or electrical business cost?

Housecall Pro lists $59 to $299 a month billed yearly depending on the plan, and Jobber starts at $49 a month, both with AI features on some tiers. A phone answering service is usually a monthly plan plus per-call fees. WorkAgent, which does the follow-up and paperwork, is a flat $149 a month or $888 billed yearly.

Will AI replace my office manager or dispatcher?

No. A dispatcher handles live calls, crew availability and judgment under pressure, and AI does none of that well. What it replaces is the repetitive follow-up that office staff fit in around the phones, so the same people have time for the work that needs a human.

Will the agent contact my customers on its own?

Only if you tell it to. By default it drafts every follow-up, reminder and notice for your approval and sends on your click. Once a routine is working, such as the 30-day invoice reminder, you can let it send that routine on a schedule. It never takes a payment or books a job.

Does it work with Housecall Pro, Jobber or ServiceTitan?

It works from what those systems export and from your inbox, calendar and shared drive. It reads the estimates and invoices exports to know what is open, drafts the messages, and gives you back a list of what to update in the job record.

Is it worth it for a small plumbing or electrical shop?

Usually most of all. A two or three van shop has no office staff, so follow-up happens at night or not at all. At $888 billed yearly the agent costs less than the margin on one typical panel upgrade, and one recovered bid or invoice often covers it.
