Accountant for Tradies and Builders in Sydney
Specialist accounting, bookkeeping, and tax services for builders, electricians, plumbers, and subcontractors. Job costing, GST on materials, subcontractor PAYG, and long payment cycles handled.
Three reasons our clients stay.
We’re a boutique accounting practice built on long-term client relationships, offering personalised tax, accounting, and advisory services to businesses and organisations across Sydney.
Twenty-three years in practice as of 2026. Same firm, same principal, same standards since 2003. Some clients have been with us almost the whole way. The work compounds, and so does the trust. Over four hundred SMSFs managed and thousands of tax returns lodged.
Tax, books, advisory, SMSF, Xero. One team that knows your business. No handoffs between firms, no missed details between specialists, no questions you have to answer twice. Numbers flow cleanly from books to BAS to tax return because the same people are looking at all of them.
We are old-fashioned about this. You get a name, a direct line, and someone who actually knows your file. We watch for trends, flag issues before they become fines, and call when something needs attention. Most clients hear from us between quarters, not just at lodgement time.
Why every accountant for tradies must understand job costing
Trade businesses run on materials margin, labour rates, and the cash flow gap between starting work and getting paid. Each job has its own cost structure: materials, labour, subcontractors, equipment, and overhead. Without proper costing, the builder cannot tell which projects are actually profitable and which are bleeding money.
Add subcontractor PAYG-W. Add GST on materials that needs to flow through correctly. Add equipment that depreciates and needs replacing. Add the long payment cycles of construction work. The financial complexity behind a trade business is well above generic small business.
A general accountant can miss legitimate deductions, mishandle subcontractor PAYG, or fail to track job profitability. Specialist trade accounting understands the cost structure, the workforce arrangements, and the cash flow patterns of the sector. Trinity has been doing this for years.

A small firm by design.
Trinity Accounting Practice opened in Beverly Hills in 2003. Ramy Hanna, a registered tax agent and Fellow of three Australian accounting institutes, has run it since. The firm has stayed deliberately small, deliberately local, and deliberately senior. The principal you talk to today is the principal who will be reviewing your return next October.
Most of our work comes from referrals. Most clients have been with us for years, some for decades. We think that says more about the work than any award would.
The reviews speak for themselves.
Sole traders, growing companies, and trustees who keep coming back. Here’s why.

What trade businesses ask before engaging us.
The questions trade businesses most often have before working with us. Same answers we give in person, just in writing.
Pricing depends on size, transaction volume, and engagement scope. Sole traders typically start at a fixed monthly fee. Larger builder operations are quoted as a package.
Yes. PAYG withholding on subcontractors is part of standard bookkeeping and BAS service. Reporting is prepared and lodged on schedule.
Yes. Project costing showing materials, labour, subcontractors, and overhead is part of advisory and bookkeeping engagements where it adds value.
Tools, vehicles, and equipment are depreciated correctly with instant asset write-off applied where it fits.
Long payment cycles are modelled against fixed costs and supplier credit so tight periods are anticipated rather than discovered when the bills arrive.
Yes. Single-trade contractors through to multi-staff builder operations all within scope.
