How to get this live in your business
Free. The Knowledge Base Build Standard: the objects, the checks in order, and the pass test.
Ready for
The job is finished, the customer is happy, and the invoice is a photograph of a docket sitting in somebody’s phone. None of that is unusual and none of it is free. Every week it stays there is a week the money is yours on paper and somebody else’s in the bank.
In short
The problem
The inbox is doing the job of a job management system. Dockets, photos, approvals and invoices arrive in one place with no structure and no status.
Why it persists
Nothing about it fails loudly. Every week a docket sits there is a week the money is yours on paper and somebody else's in the bank.
What we would automate
Capture out of WhatsApp and email, the job record built from whatever arrived, and the chasing that follows, without new software or new logins.

1. The Invoice Sitting in Your Phone
It’s 8pm on a Thursday. You finished a $12,400 re-roof three days ago. The client’s happy. The job’s done. But you haven’t invoiced yet because you need to check the final measurements against the quote, add the variation for the extra flashing, match up the three subbie invoices that came in this week, and figure out whether the skip bin charge was for this job or the one in Capalaba.
So the invoice doesn’t go out tonight either. Maybe this weekend. Probably next week.
Meanwhile, your scaffolder has texted you a photo of a handwritten invoice. Your gutter subbie emailed a PDF from Xero that went to your spam folder. And your tiler left a voicemail saying “mate, that job was $2,200 not $1,800 like we quoted. Had to cut extra tiles for the valleys.”
This isn’t a discipline problem. It’s a systems problem. Add up two numbers tonight: the completed work you have not invoiced yet, and the subbie and supplier invoices waiting to be matched to a job. Most owners who do it are surprised by the first one.
The bottom line
Those two totals are money in paperwork limbo, costing you cash flow, margin visibility, and hours of admin every week. This applies to roofers, electricians, plumbers, plasterers, painters: any trade doing work under builders.
2. Why This Hits Every Trade That Works Under Builders
Every trade that does work for restoration companies and builders (roofers, electricians, plumbers, plasterers, painters, carpet layers, fencers, gutter installers) has the same structural problem: they’re caught between doing the work and doing the admin that gets them paid for the work.
Some trades have it worse than others. A roofer might manage 5 subbies per job. A plasterer might work solo but across 30 active jobs. An electrician might have fewer jobs but stricter compliance documentation requirements.
But the core workflow is identical:
- ✓Job comes in via phone/email/WhatsApp, no structured capture
- ✓Work gets done
- ✓Invoice needs to be sent, but admin loses to being on the tools
- ✓Subbies/suppliers need to be paid, but their invoices arrive randomly
- ✓Builders chase for paperwork: invoices, photos, SWMS, compliance docs
- ✓Cash flow suffers because invoicing is always weeks behind
The smaller the operator, the worse this gets. A two-person electrical business doesn’t have office staff. The “office” is the electrician’s wife processing invoices at the kitchen table after the kids go to bed. Or more often, it’s nobody, and the invoices pile up.
3. The Real Cost of the Inbox System
When your email inbox is your job management system, five things happen, regardless of what trade you’re in:
1. Invoices get lost
A subbie or supplier sends their invoice to your personal email. It arrives between a Bunnings receipt and a newsletter. You don't see it for a week. Meanwhile, the subbie thinks you're ignoring them.
2. You can't see your margins
Without all costs matched to each job, you genuinely don't know whether a job made you 60% margin or 30% margin until your accountant tells you months later. By then it's too late to adjust your pricing.
3. Cash flow bleeds
Every day a completed job goes uninvoiced is a day you're funding someone else's project. Add up the jobs finished but not yet invoiced: that total is a loan you are carrying, interest free, and it belongs in your bank account.
4. You're always behind on builder paperwork
When you work under a restoration company or builder, they need your invoice, SWMS, and photos on time. If you're the subbie who's always late, you stop getting the calls.
5. Every builder chases you the same way
You might work under three to five different builders. Each one has their own supervisor chasing you for the same things: invoices, compliance docs, status updates. That's three to five people texting and calling about paperwork while you're on the tools.
The total cost
Most of it never shows as a line on a statement: the time, the late invoices, the margins you cannot see, the builder who quietly rings someone else. It shows as friction, delay, and work that goes elsewhere.
4. What an AI Job Manager Actually Does
An AI system built for trade businesses isn’t a chatbot. It’s not an app. It’s not another piece of software to learn. It’s an intelligent layer that sits on top of the tools you already use (WhatsApp and email) and does the organising that nobody has time to do.
Here’s what a typical day looks like with the AI running (the example uses a roofer, but the flow is identical for any trade):
6:00 am
Morning briefing lands on WhatsApp
"Good morning Dave. Active jobs: 18. Completed this week: 3. Revenue invoiced: $24,600. Needs attention: Creek Rd complete 8 days, not invoiced ($8,200). Smith St gutter invoice 5 days overdue. I've sent a reminder. Jones Ave scaffolder invoice $200 over quote. Approve or query?"
You glance at it over coffee. Reply "draft creek rd invoice." Move on.
9:15 am
Subbie sends a photo of an invoice via WhatsApp
The AI reads it instantly. Extracts: AAA Scaffolding, $1,800, 18 Jones Ave. "This is $200 above the quoted $1,600. Want me to file it as-is, or flag it for discussion with AAA?"
You reply "file it, he mentioned extra height." Done.
2:30 pm
Supervisor texts the AI number
"jones ave stripped, sarking going on tomorrow, found some rotten battens need replacing." The AI updates the job record and messages you: "Jones Ave update from Mike: strip done, rotten battens found. This may need a variation. Want me to add a variation line item?"
5:45 pm
Daily wrap-up
"3 subbie invoices received and matched. 1 variation flagged (Jones Ave battens). Creek Rd invoice drafted, ready for your review. Outstanding: Dave's Guttering still hasn't sent invoices for 2 jobs (reminders sent)."
Your part today: a handful of WhatsApp replies.
5. The Technology Without the Jargon
You don’t need to understand how this works. But here’s the short version for the curious.
Computer Vision
Reads invoices from any format: PDFs, photos of paper invoices, even a blurry photo of a handwritten receipt. Extracts amounts, dates, supplier names, and job details automatically.
Natural Language Processing
Understands text messages and voice notes. When your supervisor texts "jones ave done, starting boundary tomorrow," the AI updates both job records automatically.
Pattern Matching
Connects invoices to jobs by address, supplier name, amount, and historical patterns. After a few weeks, it matches invoices automatically without asking.
Automation Engine
Sends reminders, chases invoices, and generates daily briefings without anyone pressing a button. Works 24/7.
All of this runs through WhatsApp and email. Nothing to install. Nothing to learn. It works alongside the job tool you already run, or just a phone.
6. What It Costs and How to Count the Return
Two parts, priced differently. The calls around the paperwork are ready-made products with a monthly price. The inbox layer in sections 4 and 5 is built to your subbies and your jobs, so it is scoped before it is priced.
$199
Get Paid, per month
Overdue invoices rung against your Xero and the promised date written back; quiet quotes followed up the same way. 30-day free trial.
$119
Booked After Hours, per month
The new job taken on your number out of hours and written into ServiceM8 or Simpro during the call. Flat, no call caps.
The return is yours to count, and you can do it in a week without buying anything:
| Measure | How to count it |
|---|---|
| Completed work not yet invoiced | Add up every finished job with no invoice out, today |
| Days to invoice after completion | For the last ten jobs, the gap between finishing and invoicing |
| Subbie invoices waiting to be matched | Count them, and how long the oldest has sat |
| Owner hours on admin | Log a week of evenings and weekends spent on paperwork |
If those numbers are small, your admin already works and this paper is not your problem. If they are not, the first column says where to start.
7. What It Doesn’t Do
It doesn't replace your accounting software
Xero, MYOB, and QuickBooks handle your BAS, payroll, and tax. The AI handles the messy front end (capturing, matching, and chasing invoices), so the data that reaches your bookkeeper is already clean and organised.
It doesn't replace a job management tool
It works alongside the job tool you run. Where that tool has an open API (ServiceM8 and Simpro do; Tradify has no public API) it can write into it. If you run nothing, it keeps its own record. It doesn't force you onto new software.
It doesn't handle complex disputes
If a client is arguing about a variation or a subbie is contesting a scope, that's a human conversation. The AI gives you all the data (original quote, scope, invoice, timeline), so you walk into that conversation informed.
It doesn't work perfectly on day one
The first weeks are a learning period. The AI needs to see your subbies, your jobs, and your patterns before it can match invoices on its own, and until it has, it asks rather than guesses.
8. The Builders Are Watching
Here’s the uncomfortable truth for every trade that works under builders and restoration companies: those builders are starting to track which subbies get their paperwork in on time and which ones don’t.
A restoration company managing 100 active insurance claims can’t invoice the insurer until every subbie invoice is in. If your invoice is the one that’s 3 weeks late, you’re not just slow; you’re costing them cash flow across the entire job. They notice. They keep a list.
This applies equally to the roofer, the electrician, the plasterer, and the painter. The trade that’s on top of their admin gets more work. The one that’s always chasing paperwork gets fewer calls.
The competitive advantage
The trades using AI to manage their admin aren’t just saving time; they’re becoming the preferred subbie for every builder in their network. That’s a competitive advantage that compounds over time.
9. Where to Start
Not with the inbox. Most trade businesses need the same things first: the phone answered, the quotes followed up, and the money chased. Those are already built and run on the systems you have.
- ✓Get Paid rings the overdue invoice and the quiet quote, and records the promise to pay as a date in Xero.
- ✓Booked After Hours takes the new job out of hours and writes it into ServiceM8 or Simpro before the caller hangs up.
The WhatsApp and inbox layer in this paper is the part that genuinely is custom. Run it through the 8-minute diagnosis once the calls are running, and it will say whether it is worth building for you.
