AI for Australian tradies: quotes, invoices and enquiries

How can tradies use AI in Australia?

Tradies use AI for the paperwork around the job, not the job itself. Three workflows are worth doing: quote drafts from site photos and a voice memo, polite follow-up on overdue invoices, and after-hours enquiry capture that books work into your job management software. In all three the AI drafts, reminds or acknowledges, and you keep the price, the tone and the final say on who gets booked.

Workflow	What the AI does	What you still do	Setup time (estimate)
Quote drafting	Turns photos, a voice memo and your rate card into a quote draft	Check prices, scope and terms, then send	About 30 minutes, DIY
Invoice follow-up	Writes each reminder about the specific job and stops when the customer replies or pays	Approve the wording once; make the call at step three	A few days to build and test
After-hours enquiries	Replies within minutes, asks the right questions, books into ServiceM8	Handle emergencies and anything unusual	7–10 working days, done for you

Setup times are our estimates for a sole trader or small crew that already has a rate card and uses Xero.

Does ServiceM8 have AI? What about Tradify, Fergus and Xero?

Yes. As at October 2026, every ServiceM8 plan, including the free one, includes AI Smart Helpers: a writing helper for emails and texts, AI quote and invoice drafting, and a voice assistant. Tradify includes AI tools on its Plus plan, Fergus has Fergus AI, and Xero’s JAX drafts invoices and quotes at no extra charge. Switch on the AI you already pay for before buying anything new.

Software	Plans (as at October 2026)	AI included
ServiceM8	Free $0, Starter $29, Growing $79, Premium $149, Premium Plus $349 a month (incl GST)	AI Smart Helpers on all plans: writing helper, quote and invoice drafting, voice assistant
Tradify	Lite $48, Pro $52, Plus $62 a user a month (ex GST)	AI tools on the Plus plan
Fergus	From $53 a month	Fergus AI
Xero	Grow $78, Comprehensive $107, Ultimate $143 a month (incl GST)	JAX categorises and matches bank transactions, answers questions about your numbers, and drafts invoices and quotes

Built-in AI only sees what is in its own app. The gaps are the hand-offs: photos on your phone, a rate card in a spreadsheet, enquiries arriving at 9pm. That is where Claude, ChatGPT or a small custom build fits. On AroFlo or MYOB, check your plan’s current feature list.

What should a tradie automate first?

Start with quote drafting. You read every quote before it goes out, so a bad draft costs you a minute rather than a customer, and quotes are often the paperwork left until late at night. Once quotes are reliable, automate invoice follow-up, which touches money and relationships. Leave after-hours enquiry capture until third, because it talks to new customers while you are not watching.

Can AI write quotes for a plumber or electrician?

Yes, as a draft. Give Claude or ChatGPT four to eight site photos, a 60-second voice memo and your rate card, and it writes the scope, itemises labour and materials, adds GST and your standard terms in a minute or two. It only knows the prices you give it and cannot judge a tricky job, so you check every line and stay the estimator.

The setup that works:

1. One saved project (in Claude or ChatGPT) holding your rate card, quote template, terms and a few past quotes.
2. A hard rule: any item not on the rate card is marked “PRICE NEEDED”, never guessed.
3. On site: photos of the work area, close-ups and model numbers, plus a voice memo of what the customer wants and what you found.
4. Back in the ute: paste the transcript and photos, check prices, GST, deposit terms and scope, then copy the quote into ServiceM8, Tradify or Fergus so your job system stays the record.

The free guide to quote drafting from photos and voice memos has the exact instructions and rate card template. Rough estimate, assuming ten quotes a week and a 30-minute write-up becoming a 5-minute check: about four hours back a week. Keep customer details to what the job needs; see what is safe to put into Claude or ChatGPT.

Can AI chase overdue invoices for tradies?

Yes. Xero can send automatic reminders before and after the due date, and weekly until paid. An AI layer on top writes each reminder about the specific job in your voice, reads the replies, pauses the moment a customer disputes the work or asks for time, and hands the hard cases back to you. The tone matters as much as the timing: a late payer is often busy, not dodging you.

A polite three-step cadence (adjust the days to your payment terms):

Step	When	Tone	What it says
1	3 days overdue	Friendly	Names the job and date, the amount and a payment link: “this may have slipped through”
2	10 days overdue	Clear and polite	Restates the amount, asks whether anything about the job needs sorting, offers a payment plan
3	21 days overdue	Firm, still courteous	Says you will call. The AI stops emailing, alerts you and drafts a short call script

Three rules for the instructions. Name the real job (“the hot water service in Brunswick on 12/09/2026”), never “your account”. No threats: debt collectors and legal action are your call, made in person. Stop on any reply: a question, a complaint or “I’ll pay Friday” goes to you. A trades business lives on repeat work and referrals, so a reminder that reads like a debt notice can cost more than the invoice is worth.

Can AI answer my after-hours enquiries?

Yes, in writing. An AI front desk on your website chat, SMS and email replies within minutes at 9pm, asks what the job is, where and how urgent, answers routine questions such as suburbs covered and the call-out fee, then books the job into ServiceM8 or queues it for the morning. Genuine emergencies get a holding reply with your after-hours number and an alert to your phone.

How it runs:

1. Acknowledge every enquiry within minutes, saying it is an AI assistant for your business.
2. Qualify the job: type of work, suburb, urgency, photos if useful.
3. Book into ServiceM8 inside the windows you set, and confirm by SMS. It never prices the job itself or asks for card details.
4. Escalate emergencies (gas smell, flooding, sparking, no power) and complaints to you straight away, with a one-line summary.

The complete guide to AI receptionists covers costs, the rules and how to test one before customers see it.

Should a tradie use an AI voice agent to answer the phone?

Not as the first step. Phone voice agents still mishear Australian accents, suburb and street names, and trade terms such as “TPR valve” or “the RCD keeps tripping” more often than written channels go wrong, and a misheard address means a wasted trip. Catch enquiries in writing first, then test any voice agent hard against recordings of real calls before it answers a customer.

A common middle ground is a missed-call text-back: the caller gets an SMS inviting them to text the details, and the conversation carries on in writing, where every message is logged.

Do AI follow-up messages have to follow the Spam Act?

Promotional ones do. Messages about a job the customer asked for, such as a quote, a booking confirmation, an “on my way” text or an invoice reminder, are generally not marketing. Anything that promotes your business, such as a winter hot water special, a “book your annual service” offer or a newsletter, is a commercial message under the Spam Act: it needs consent, must identify your business and must carry a working unsubscribe.

Under the ACMA’s Spam Act rules, unsubscribes must be actioned within five working days. Mixing the two is where businesses slip: in March 2026 Lululemon paid $702,900 over more than 370,000 emails, including order emails with marketing content, sent without an unsubscribe. Keep job messages factual and promotions for customers who said yes.

How much does AI cost a small trades business?

Often very little. As at October 2026 the AI inside ServiceM8 and Xero’s JAX is included in your plan, and Claude Pro or ChatGPT Plus for do-it-yourself quote drafting is US$20 a month (about A$33 including GST at checkout; check current pricing). Done-for-you builds from On Autopilot start at $497 one-off, and an after-hours AI Front Desk costs $1,500 to set up plus $199 a month.

Off-the-shelf software subscriptions used in the business are generally deductible operating expenses, per the ATO.

What won’t AI do for a trades business?

AI will not visit the site, make the technical call or carry your licence. It cannot see behind a wall, decide whether a switchboard needs upgrading or which fitting suits an old system, sign a compliance certificate, or do licensed plumbing, gas or electrical work. It drafts, reminds and books. The judgement, the price and anything you put your licence number to stay with you.
