Profit You Can See Per Job

We set up job costing so every site shows its own margin. You stop guessing which contracts are carrying you and which are quietly losing money.

What Construction Businesses Ask Before They Switch

Do you lodge the Taxable Payments Annual Report (TPAR) for me?

Yes. If you are in the building and construction industry and you pay subcontractors, you must lodge a TPAR each year by 28 August. We prepare it straight from your Xero or MYOB file, reconcile it against your subbie payments, and lodge it with the ATO on time so you are never chasing it at the last minute.

Can you set up job costing so I know which sites are profitable?

Yes. We build tracking categories in Xero for each job or site, code your income, materials, labour and subcontractor costs to them, and give you a profit read per project. You stop finding out at year end that a job you thought went well actually lost money.

How do you handle retentions and progress claims?

We account for progress claims as you invoice them, hold retentions correctly on the balance sheet rather than recognising them as income too early, and track work in progress so your reports reflect what you have actually earned. It keeps your GST and your tax position accurate as jobs run over multiple quarters.

Should my construction business be a sole trader, company or trust?

It depends on your income, your risk and whether you take on staff. Construction carries real liability, so once you are earning well or hiring, a Pty Ltd or a trust structure usually protects your assets and saves tax. We run the numbers on your situation before you commit to anything.

I have unlodged BAS and returns. Can you catch me up?

Yes, we clear construction backlogs every week. We lodge the oldest first, work forward in sequence, and negotiate an ATO payment plan if there is a debt. Most clients are fully caught up within 60 days and then kept current from there.
