Why Trinity

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.

  • Longevity that compounds

    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.

  • Everything under one roof

    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 pick up the phone

    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 specialist accounting matters

Why every accountant for retail businesses must understand inventory

Retail businesses run on inventory turnover, gross margin, and the cash flow gap between buying stock and selling it. E-commerce adds platform fees, shipping costs, and the GST treatment of cross-border sales. Each channel has different margin profile, different fees, and different reconciliation work.

Add inventory accounting that tracks COGS at the SKU level. Add multi-platform sales requiring reconciliation. Add seasonal patterns and the cash flow tied up in stock. The financial work behind a retail business is sector-specific.

A general accountant can mishandle inventory accounting, miss legitimate deductions, or fail to reconcile platform sales correctly. Specialist retail accounting understands the inventory work, the platform fees, and the multi-channel patterns of the sector.

  • Inventory invisibility

    Without SKU-level inventory tracking, the retail business cannot see margin per product or identify slow-moving stock.
  • Platform reconciliation

    Shopify, WooCommerce, Amazon, and eBay each report differently. Without reconciliation, sales numbers drift from bank deposits.
  • Online sales GST

    GST on imported goods, exported goods, and digital products has specific rules generalists often miss.
  • Multi-channel reporting

    Revenue split across retail, online, and wholesale needs separation to see what is actually paying.

About Trinity Accounting

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.
