GST from their ABN: “Tax Invoice” only for GST-registered subbies

Approve 9 clean invoices

The problem

Every invoice arrives in a different format

Pen and paper, part PDF, part Word doc, and often not ATO-compliant. Someone in the office has to reconcile or reformat every one before it can be paid.

Hours don’t match the site

Invoices are reconciled over email and messages, so mismatches turn into disputes.

No proof they were there

With no subbie time tracking there’s nothing to compare, and overbilling eats fixed-price profit.

Not the agreed rate

Rate changes often aren’t recorded in the system or the contract.

Late, or not at all

Forgotten invoices miss the pay run and give you a misleading labour cost.

In the office

A three-way check every pay run

Invoice, timesheet and supervisor, all checked by hand, plus hours reported by phone that get missed or forgotten.

How it feels

Paying on trust, and stuck being the one who argues

You approve invoices hoping they’re right, and every mismatch means another awkward call with a subbie you need back on site on Monday.

It’s just wrong

An invoice shouldn’t be taken on trust

Contractors shouldn’t have to take a subbie’s invoice on trust, or pay someone to rebuild it before it can be paid.

What you get

Invoices that fill themselves, and check themselves

Subbies invoice from their phone in your format, and an AI invoice agent checks every line against site hours and the agreed rate before you pay.

Invoices raised from the subbie’s phone

In your format, so every invoice arrives complete, on time and ready to pay.

  • Your format
    One invoice template for every subbie.
  • Filled from their timesheet
    Line items come from approved hours.
  • GST from their ABN
    “Tax Invoice” only when GST-registered.
  • Sent from their phone
    App Store, Play Store or mobile browser.

An AI check on every line

Hours are compared with GPS site hours and the rate with the agreed rate, so you only pay for hours that happened, at the rate you agreed.

Any mismatch shows the hour and dollar difference. Hours with no check-in behind them are flagged.

Corrections and approvals in one place

Send a correction request with a reason. The subbie fixes and resubmits from their phone, and every step is logged, so a dispute takes a tap, not an email chain.

Costs land on the right job

Once approved, the invoice is allocated to the project budget with the hours behind it, so every job shows its real labour cost.

  • Approved hours allocated to the project budget.
  • Works with Xero and MYOB.

The plan

Checked subbie invoices in three simple steps

  1. 01

    Add your subbies

    Name, mobile and agreed hourly rate. We set up your invoice template and sites during onboarding.

  2. 02

    Subbies check in on site

    Their GPS-checked hours build the timesheet the invoice is drawn from.

  3. 03

    They tap invoice, you approve

    At the end of the week, hours and rate fill in and they submit from their phone. You open one screen: clean invoices ready to approve, mismatches flagged.

No double handling

The invoice fills itself from hours already clocked.

Easy for subbies

They only check the invoice and tap send.

Only the mismatches

Your team checks the lines that don’t match, not every invoice.

30-day trial

Start with 3–5 of your regular subbies.

Worried it’s double handling, or that your subbies won’t do it?

The invoice fills itself from the hours they’ve already clocked, so subbies only check and tap send. Your team only looks at the lines that don’t match. Start with 3–5 of your regular subbies for a 30-day trial.

We get it

We know every pay run means a three-way check of invoice, timesheet and supervisor.

So we built an AI invoice agent that compares subbie invoices with the hours recorded on site, and highlights mismatches in hours and rates.

“None of them really offer the built-in invoicing and AI automation. That’s something that captured our attention.”

Trade contractor, comparing tools

“They can’t check in or check out unless they’re within the vicinity of the project.”

Trade contractor, on GPS-checked hours

“It’s much better… there’s been lots of improvements.”

What you have

A pile of PDFs, Excel sheets, handwritten invoices and emails, a timesheet in another system, and a spreadsheet to match them

What you have

One invoice per subbie, raised from their phone, already matched to their site hours and agreed rate

How it feels

Paying on trust, and dreading the mismatch conversations

How it feels

Confident. You know what you’re paying for, and the evidence is on screen if a question comes up

An average day

Chasing late invoices, reformatting them, checking every line against timesheets, emailing variances, then keying payments into Xero and the bank

An average day

Open the invoice screen, approve the clean ones, and send the flagged ones back with a reason

A year of rounded-up hours from 10 subbies, without a single dodgy invoice.

A subbie who rounds up half an hour a day at $55/hr costs you $137 a week, about $6,600 a year. Billing $60 instead of the agreed $55 adds $40 on an 8-hour day, or $9,600 a year per subbie. And if the only record is a sign-in sheet or a WhatsApp message, you can’t prove the hours either way, so you pay what’s invoiced.

FAQs

Can't find the answer you're looking for? Chat to our team.

Do subbies need to download an app?+

No. Swift Checkin is on the App Store and Play Store, but it also runs in a mobile browser.

Where do the invoice line items come from?+

From the subbie’s approved timesheet, built from their GPS-checked hours on site. Hours and rate fill in; they check them and submit from their phone.

How is GST handled?+

GST is worked out from the subbie’s ABN, so “Tax Invoice” appears only when they’re GST-registered.

What does the AI check?+

Every line. Hours are compared with GPS site hours and the rate with the agreed rate. Any mismatch shows the hour and dollar difference, and hours with no check-in behind them are flagged.

What happens when an invoice doesn’t match?+

You send a correction request with a reason. The subbie fixes it and resubmits from their phone, and every step is logged.

Does it work with Xero and MYOB?+

Yes. And once an invoice is approved, it’s allocated to the project budget with the hours behind it.

Every subbie invoice paid once, correctly

On time and in your format, checked line by line against site hours and agreed rates, without anyone rebuilding it or arguing over it.
