AI agents for tradies · The Back Office

Not a chatbot. A team.

A whole back office for your trade business, run from the same WhatsApp thread you already live in. Four AI agents handle the money, the admin, the marketing and the overview. You stay on the tools.

Straight answer

Most "AI for tradies" is a receptionist: it answers the phone. Useful, but the phone was never the whole problem. The problem is the two hours of admin after knock-off: the invoices, the quote that never got a follow-up, the Xero mess before BAS, the Google presence you have not touched since 2023.

The Back Office is an AI team, not a chatbot. Four agents with real jobs: Finance, Operations, Marketing and a CEO agent that keeps the overview. You run them from WhatsApp, and nothing ever reaches a customer without your thumbs up.

What is the difference between an AI team and an AI receptionist?

The AI receptionist category is crowded and it does one thing: it picks up when you cannot, takes the caller's details and books the job. That is answering the phone. It sits at the front of the business.

An AI team runs the business behind the phone. When the job is booked, someone still has to invoice it, chase the payment, reconcile it in Xero, follow up the quote from last Tuesday, ask the happy customer for a review and tell you how the month is tracking. In most trade businesses that someone is you, at the kitchen table, after dinner.

That is the work The Back Office takes. It is not a voice on your phone line and it never talks to your customers. It is the office staff you have not been able to justify hiring, delivered as AI agents you direct from your ute.

If all you want right now is the phone answered, that is a different product and an honest read on it is here: AI receptionists for Australian trades, what they do and cost.

What do the four agents actually do?

Agent 01 · Finance

The money agent

Invoicing, payment chasing, receipts and supplier bills coded into Xero, books kept BAS-ready for your accountant, and a Monday morning money report so you start the week knowing exactly where you stand.

On the toolsYou finish a switchboard upgrade in Randwick, message "invoice that one, 4 hours plus the board". A drafted invoice comes back for your thumbs up, then it lands in Xero and goes out. Ten days later, if it is unpaid, a polite chaser is drafted and waiting for your approval.

Agent 02 · Operations

The admin agent

Scheduling, job admin and the quote follow-ups that quietly die in your sent folder. It keeps the pipeline honest: every quote has a next step, every job has its paperwork.

On the tools"Quote for the Maroubra reno went out 6 days ago, no reply. Here is a short follow-up text for the builder, send it?" One thumbs up from smoko and the quote is back in play instead of forgotten.

Agent 03 · Marketing

The presence agent

Content drafts, Google review requests after finished jobs, and keeping your online presence alive so you are not invisible the next time someone in your suburb searches for your trade.

On the toolsJob wrapped and paid? It drafts the review request for that customer and a short before-and-after post from the photos you took, then waits. Nothing is posted, nothing is sent, until you approve it.

Agent 04 · CEO

The overview brain

The one you actually talk to. It sees what the other three are doing, answers plain questions about your business and flags what needs your attention before it becomes a problem.

On the toolsYou ask "how are we tracking this month?" and get a straight answer: what is invoiced, what is owed, which quotes are still open, what is booked next week. One question, one thread, no logging in to anything.

The Thumbs-Up Rule

Nothing reaches a customer without your approval. Every invoice, follow-up, review request and post is drafted, shown to you in WhatsApp, and held until you give it a thumbs up. The agents work for you. They never speak as you without your say-so.

What does a day with an AI back office actually look like?

Here is a realistic day for a sparkie running a one-man-and-an-apprentice operation out of the Eastern Suburbs, entirely from the WhatsApp thread in his pocket.

6:40 AM
Coffee, ute, Monday money report. The Finance agent has the week's picture waiting: what got paid, what is outstanding, what is due out. Two minutes of reading instead of half an hour in Xero.
7:15 AM
Driving to the first job. The Operations agent confirms today's run and flags that Thursday has a gap since a job pushed back. It suggests offering the slot to the quote that is waiting on a start date. Thumbs up at the red light.
9:50 AM
Smoko. Two drafts waiting: a chaser for an overdue invoice and a follow-up on a quote that has gone quiet. Both read like he wrote them. Two thumbs up, back to the switchboard.
12:30 PM
Trade counter run. He photographs the supplier receipt and drops it in the thread. The Finance agent codes it against the job in Xero. No shoebox, no lost GST claim at BAS time.
2:20 PM
A customer asks to move Friday's job. He forwards the text. Operations checks the week, proposes a new slot and drafts the reply. He approves it and keeps working.
4:45 PM
Job done, photos taken. "Invoice it" is the whole instruction. Finance drafts the invoice, Marketing drafts the review request for once it is paid. Both queued for his thumbs up.
5:30 PM
Knock-off. The CEO agent sends the day's wrap: what went out, what came in, what is waiting on him tomorrow. The laptop stays in the bag. The evening is his.

No part of that day required a login, a dashboard or a desk. The admin still happened. It just happened in the gaps of the day instead of eating the night.

Who is it for, and who is it not for?

Built for you if

You run a trade business in Australia: sparkie, plumber, chippy, builder, painter, landscaper, cleaner, HVAC
You are the one doing invoices and quote follow-ups at night
You use Xero, or you know you should
You live in WhatsApp already and want zero new software
You want help with admin but want final say on everything a customer sees

Not for you if

You already have a full office team and the admin is under control
You want an AI to answer your phone: that is a receptionist product, not this
You want a fully autonomous system messaging customers without your approval: we will not build that
You are looking for a cheap DIY chatbot template to configure yourself

How does it fit the tools you already use?

The Back Office is built around the standard Australian trade stack, not against it.

Tool	How the team works with it
Xero	Core to the Finance agent: invoicing, payment chasing, receipt and bill coding, books kept clean and BAS-ready for your accountant. Your accountant stays your accountant; they just inherit tidier books.
ServiceM8 / Tradify	If your jobs live in a job management app, the team is scoped around it during setup so scheduling and job admin work with what you have rather than forcing a migration.
WhatsApp	The entire interface. Reports come to you there, drafts wait for approval there, and "invoice that one" is a complete instruction.
Google presence	The Marketing agent drafts review requests and content to keep your profile alive, all held for your approval before anything goes public.

Frequently asked questions

What is the difference between an AI agent and a chatbot?

A chatbot waits for a message and answers it. An AI agent does work: it reads your Xero, drafts the invoice, notices the quote that got no reply and prepares the follow-up. The Back Office is a team of four agents with defined jobs, run by you from WhatsApp. You approve, they execute.

Do my customers talk to the AI?

No. The Back Office is owner-facing. Your customers deal with you, the same as always. The agents work behind the scenes on invoices, scheduling, follow-ups and content, and under the Thumbs-Up Rule nothing is ever sent to a customer until you approve it in WhatsApp.

Does it work with Xero, ServiceM8 or Tradify?

Xero is core: the Finance agent works directly with your Xero for invoicing, payment chasing and keeping the books BAS-ready for your accountant. If you run jobs through ServiceM8 or Tradify, the team is set up around your existing stack rather than replacing it. Setup is scoped to your tools during onboarding.

Do I need to be good with technology to use it?

If you can use WhatsApp, you can run the team. There is no dashboard to learn, no software to install and no logins to remember. You message the team like you would message an office manager, and you approve work with a thumbs up.

Can the AI send an invoice or message a customer without my approval?

No. The Thumbs-Up Rule is built into the system: any invoice, quote follow-up, review request, social post or customer message is drafted and shown to you in WhatsApp first. Until you give it a thumbs up, it does not go anywhere.
