Track job costs, manage payroll, control cash flow, and stay compliant with Australian tax obligations.

Contracting businesses operate on tight margins, multiple job sites, subcontractors, and staged payments. Without accurate financial systems, project overruns, cash flow gaps, and tax issues can quickly arise.

Collab Accounting Australia provides specialised bookkeeping and accounting services for contractors across construction, trades, and project-based industries. We help you track job costs, manage payroll, control cash flow, and stay compliant with Australian tax obligations.

Job Costing & Project Tracking

We allocate labour, materials, equipment, and overhead costs to each project. Accurate job costing ensures you know which jobs are profitable and where costs are rising.

Progress Billing & Invoicing

Manage milestone billing, variations, and retainage with clear documentation. We help reduce payment delays and maintain steady cash flow.

Payroll & Subcontractor Management

Process payroll accurately, manage superannuation, and track subcontractor payments. We ensure compliance with Australian employment regulations.

BAS, GST & Tax Compliance

We prepare and lodge BAS, manage GST obligations, and track deductible expenses to keep your business compliant with ATO requirements.
