Small Business Accountant for Tradies

How this usually works

A focused “for tradies” process starts with a short review: business structure, software stack, job flow, invoicing, payroll, and any ATO deadlines. From there, work splits into three layers.

1) Immediate triage. Fix urgent issues such as overdue BAS, payroll/STP errors, missing super, unpaid invoices, or TPAR preparation. Where needed, clean up bank feeds, GST codes and account mapping so BAS figures reconcile.

2) Process design. Map how quotes, purchase orders, timesheets and supplier bills move through your tools. Connect field apps (ServiceM8, Tradify, simPRO, Fergus, AroFlo, Buildxact) to Xero/MYOB/QuickBooks. Set rules for GST, materials vs labour, deposits, progress claims and retentions.

3) Ongoing review. Monthly or quarterly check-ins for BAS, payroll, super, job profitability, WIP, and cash flow. You should know which jobs make money, which clients pay slow, and which crews are over hours.

Australian context to keep in view

• BAS and GST. Most tradies lodge quarterly. Accurate GST coding on fuel, materials, tools, licences and vehicle expenses prevents “BAS surprises.”
• TPAR. If you pay subcontractors in building and construction, you likely need to lodge the Taxable Payments Annual Report.
• Payroll and super. STP reporting, super guarantee, apprentices/trainees and allowances need correct setup in your payroll system.
• Vehicles and tools. Ensure logbooks, cents-per-km or business-use percentage are applied consistently. Track assets and warranties.
• Job costing and WIP. Split labour and materials, handle deposits and progress claims, and reconcile supplier bills to jobs to protect margin.
• Structure and risk. As profits and risk grow, compare sole trader vs company/trust with a registered tax agent. Time any change to reduce disruption.

What to compare before you commit

Common scenarios we help tradies with

• Start-up setup. ABN, GST, software, chart of accounts, receipt capture and quoting-to-invoice workflow. See also: new business accountant.
• Cleanup and catch-up. Reconcile months of bank feeds, fix GST codes, rebuild payroll, lodge overdue BAS and prepare TPAR. See: BAS agent services.
• Job profitability. Implement job costing, WIP and progress claim tracking so pricing stays sharp and margin is clear.
• Payroll and apprentices. STP, super, allowances, leave and award settings with simple approvals. See: payroll services.
• Switching providers. Handover plan, document review and a clear first-90-days roadmap.
• Tax planning. Structure reviews and timing of major purchases for cash flow and tax benefits. See: tax accountant.

Best next steps

Write the outcome you want in one sentence: “Clean BAS and payroll,” “Quotes and progress claims that reconcile,” or “Job profitability by crew.” Shortlist providers against that outcome, not just a job title.

Ask each provider to outline the first 30–90 days, what they will automate, who does what each week, and how you will see results. Review sample reports and a real-world example of job costing for tradies.
