The problem

You don't know a job's over budget until it's too late

Job cost data arrives late and lives in five places. Hours sit on a paper sign-in sheet or in WhatsApp, the quote in an estimating tool or Excel, job costs in another spreadsheet. Nobody joins them up until the month-end claim or the last invoice, and by then the overrun is already paid for.

Cost overruns found by accident

"Oh, no. Look at this excel sheet, we're over budget by $20,000 on that project."

Margin invisible until the job closes

"It doesn't tell you your overall margin on the job until the very last invoice."

Variations done, never claimed

"We're just not getting on top of it quick enough, so we miss the window to charge them."

Leakage every day

"That's why the 8 hour job took nine hours." Checked weekly, tracked in someone's head.

For the owner

"I was unaware of that till just now"

Blindsided, and flying blind on the numbers that matter most. "I don't understand how you run a business without completely understanding what your costs are." - Commercial Electrical Contractor, Sydney.

For the PM

"Why are we not progressing against the hours?"

Stretched thin and checking by hand. "We need to manually see… and obviously raise a flag."

It's just wrong

You shouldn't have to wait to find out

Contractors shouldn't have to wait for months or the last progress claim to find out whether a job made money.

Pay rate vs true cost

Is your budget hiding the overrun?

"We might pay a guy $55, but his cost is $92." A budget built on actual rate card can show the difference. Move the sliders to see the labour cost it leaves out each week.

Crew size 30
Pay rate ($/hr) 55
True cost rate ($/hr) 92.70

Labour cost missing from a pay-rate budget, per week (38 hrs per worker)

$42,978

A 69% gap between pay rate and true cost

What you get

An early warning on every job, every day

Your crew's check-ins feed a live budget on every job without admin manually doing it.
AI-agent watches it against the hours you priced and the work done, and tells you while there's still time to fix it or claim it.

A live labour budget on every job

Each GPS check-in lands on the job's budget, at your real cost rate, with approved variations added, so you see daily burn vs quote without admin typing a number.

  • From check-ins
    Built straight from GPS check-ins, no data entry.
  • Real cost rate
    Cost loaded from your rate card, not just the pay rate.
  • Variations
    Approved variations added to the budget.
  • Daily burn
    Hours burned vs estimated on every job.

An AI early warning before a job goes over-budget

The AI compares hours burned with work done and the priced hours. It alerts you and your PM when a job or cost centre is trending over, so you move the crew or fix the problem mid-job, not at the last invoice.

7:15am: "12 Castle St has used 70% of its hours and is 45% done."

A variation catcher

It flags hours booked on day-docket or out-of-scope work with no approved change order, and totals the hours in each claim period, so you claim every hour while the window is still open.

  • Day-docket and out-of-scope hours flagged.
  • Hours totalled for each claim period.

Job costing in one place

Job costing, crew hours, subbie invoices and a live WIP report together, so you know the margin on every progress claim, not just the last one.

The plan

Your first early warning, the same week

  1. 01

    Book a 20-minute walkthrough

    Bring one live job's quote: hours and rate card.

  2. 02

    We load it for you

    Send your estimate or job cost Excel sheet and crew list. We set up the geofence, pay rates and true cost rates.

  3. 03

    Your crew taps check-in

    They get an SMS and register in under a minute. That's all they do. That week you get a daily burn chart on the job, and an alert the moment it starts trending over.

One check-in

One tap for the crew, on every job.

Loaded cost rates

Budget on your real cost rate, entered once.

AroFlo, SimPRO & more

Works alongside the platforms you already have.

Xero & MYOB

Payroll still flows to Xero or MYOB.

Worried it's another system on top of what you've got?

It works alongside AroFlo, SimPRO or any other platform you have, with one check-in for the crew, and payroll still flows to Xero or MYOB. We set it up, the office needs about two hours of training. Try it on 2–3 live jobs first; keep your data and export any time.

We get it

We know what it's like to open the job costing excel sheet  and find you've been losing money for weeks.

And that the variation you could have claimed is already too late. Swift Checkin was built to solve this problem for business owners: a live cumulative cost of every job, from the crew timesheets.

54% of the construction workforce isn't on your payroll

Contractors and subbies now outnumber in-house staff. Their hours are the hardest labour cost to forecast, and the first to blow out. (KPMG, Global Construction survey, 2026).

"That's automatically being updated by the crew clocking in and out. That's really good."

Auto-tracked $10M+ labour cost without any admin effort and made companies profitable.

Budgets built straight from GPS check-ins with no admin data entry. Xero partner and MYOB export.

Before & after

Why Swift Checkin stands out?

Before
After

A quote in an estimating tool or Excel, hours spread across multiple apps and WhatsApp, cost rate in another spreadsheet, and manually build the job costing every week.

One live labour budget per job, fed by every check-in, with variations, daily burn and an early warning

Blindsided. "I was unaware of that $18K overrun till just now." Hoping the job lands on budget

In control. You get an overrun alert while it's still small enough to fix

The PM rings the crew to ask what got done. Admin types hours in from photos. The owner finds the loss at the last invoice or the month-end claim

7:15am: "12 Castle St has used 70% of its hours and is 45% done." The PM moves two guys or raises the variation that day

The owner who tracks it "in his head" and hopes

The contractor who knows the margin on every progress claim, and takes on more jobs with confidence

$18K

Over budget on a commercial job, and the client won't pay it as a variation

It's one extra hour a day across a crew of four. Ten weeks later, that's 200 unbilled hours and $18,540 at true cost. The AI cost predictor flags the drift in week one, while you can still raise the variation or pull the crew back. Construction was 26% of Australian insolvencies in FY24 (Building 4.0 CRC).

FAQs

How does the AI know a job is going over?+

It compares the hours burned with the work done and the hours you estimated, every day. When a job or cost centre is trending over, it alerts you and your PM.

Is this another system on top of what we've got?+

It works alongside AroFlo, SimPRO or any other platform you have. Let the Swift protect your profit and stops cost overruns. Payroll still flows to Xero or MYOB.

Where does the budget come from?+

From your quote or job cost Excel sheet. We load it for you, and every GPS check-in lands on the job's budget with no admin data entry.

Our real costs are higher than pay rates. Does the budget allow for that?+

Yes. You budget on your loaded cost rate, entered once, so the burn reflects what each worker really costs.

How does it help with variations?+

It flags hours booked on day-docket or out-of-scope work with no approved change order, and totals them in each claim period, so you can claim them while the window is open.

I don't have time to learn it. How long does setup take?+

We set it up for you. The office needs about two hours of training, and site crew needs no training. Your crew gets an SMS and registers in under a minute.

Will it work on our jobs?+

Try it on 2–3 live jobs first. You keep your data and can export it any time.

Fix it or claim it before the invoice goes out
