Roofing businesses face unique financial challenges. From large commercial projects to emergency residential repairs, roofers need to manage labour, materials, subcontractors, and administrative tasks while keeping their business profitable. One of the most common problems we see is disorganised bookkeeping — which can lead to cash flow issues, BAS mistakes, GST errors, and payroll headaches.

For roofers across Caboolture, Moreton Bay, North Brisbane, and the Sunshine Coast, staying organised with finances is crucial for maintaining profitability and compliance. In this guide, we’ll outline practical strategies to help roofers stay on top of BAS, GST, payroll, and job costing.

Why Organisation Matters for Roofers

Roofing projects often involve:

  • Multiple jobs in different locations

  • High-cost materials like tiles, metal sheets, insulation, and safety equipment

  • Subcontractors for specialised work

  • Vehicle and equipment expenses

  • Compliance obligations including GST, PAYG, and superannuation

Without proper bookkeeping and organisation, it’s easy for costs to slip through the cracks, invoices to be delayed, and compliance mistakes to occur — all of which can impact profits and risk ATO penalties.

Common Bookkeeping Challenges for Roofers

1. Missing or Delayed Invoices

Roofers often work on tight schedules, climbing roofs and completing multiple jobs daily. Sending invoices can easily be delayed, affecting cash flow and the ability to pay staff or suppliers.

2. Poor Job Cost Tracking

Without tracking the costs of materials, labour, and subcontractors per job, roofers may underestimate project expenses and undercharge clients.

3. GST Errors

Roofing materials and services have GST implications. Misclassifying purchases or sales can lead to inaccurate BAS lodgements and penalties.

4. Payroll and Superannuation Mistakes

If your roofing business employs staff or subcontractors, mistakes in payroll and superannuation payments can result in legal issues and ATO fines.

5. Disorganised Record Keeping

Losing receipts, misplacing paperwork, or not having a clear system for financial tracking complicates BAS, GST, and payroll management.

Simple Ways Roofers Can Stay Organised

1. Implement a Reliable Bookkeeping System

Use cloud-based accounting software like Xero, MYOB, or QuickBooks. These platforms allow you to track income, expenses, GST, payroll, and job costs in one place. Cloud systems also provide mobile access, making it easier for roofers on-site to log materials and time.

2. Track Each Job Separately

Every roofing project should have a dedicated record of:

  • Materials used

  • Labour hours

  • Subcontractor costs

  • Equipment and vehicle expenses

Job-level accounting ensures you know exactly which jobs are profitable and which may need pricing adjustments.

3. Maintain Accurate Receipts and Documentation

Save receipts digitally for materials, tools, vehicles, and business expenses. Accurate records make BAS and GST lodgements simple and support deductions in case of an ATO audit.

4. Send Invoices Promptly

Automate invoicing to ensure clients receive their bills immediately upon job completion. Automated reminders for overdue invoices help maintain cash flow without constant manual follow-up.

5. Separate Personal and Business Finances

Use dedicated business bank accounts to simplify GST tracking and BAS preparation. Mixing personal and business expenses increases the risk of errors and complicates compliance.

6. Use Payroll Services or a BAS Agent

Outsourcing payroll ensures staff are paid accurately, superannuation is calculated correctly, and PAYG obligations are met. A BAS Agent can also handle GST and BAS lodgements for roofers, reducing compliance risks.

Benefits of Professional Bookkeeping for Roofers

  1. Improved Cash Flow: Timely invoicing and expense tracking ensure money is available when needed.

  2. Accurate BAS & GST: Minimise errors and ATO penalties.

  3. Efficient Payroll Management: Staff and subcontractors are paid correctly and on time.

  4. Better Job Profitability Insights: Understand which projects deliver the best returns.

  5. Time Savings: Focus on roofing work rather than paperwork.
