William Buck

If you’re in Australia, I’d split “best accounting firms” into two buckets: firms to hire and accounting software/products people actually use. For most individuals and SMEs, the best choice is often not a Big Four firm—it’s a good mid-tier or local registered tax agent using Xero/MYOB well.

Quick recommendation

Best accounting firms/brands to consider

Australia’s largest accounting firms are still the Big Four — Deloitte, EY, KPMG and PwC — and each had over A$2 billion in revenue on the AFR 2025 Top 100 list, so they’re the default for complex corporate work. But for mid-sized companies and SMEs, mid-tier firms are often better value and more hands-on. (intheblack.cpaaustralia.com.au)

Top accounting firm brands in Australia

1. Deloitte Australia

Best for: large corporates, advisory, transformation, audit, risk, tax.
Choose Deloitte if you need scale, specialist teams, or board-level advisory.

2. EY Australia

Best for: assurance, tax, transactions, sustainability, complex corporate clients.
EY Australia reported A$2.72 billion revenue for FY25, despite a 2.9% fall from the prior year. (ey.com)

3. KPMG Australia

Best for: audit, tax, deals, risk, government/corporate advisory.
A strong choice for larger organisations needing deep technical capability.

4. PwC Australia

Best for: large corporate tax, assurance, deals, consulting—though assess fit carefully given the reputational issues of recent years.
PwC remains a major brand, but many Australian businesses now compare Big Four options more closely rather than defaulting to PwC.

5. BDO Australia

Best for: mid-market, private business, family groups, SMEs that need serious technical capability without Big Four pricing.
BDO is the standout mid-tier brand: it ranked in Australia’s top five accounting firms in the AFR 2025 list and reported about A$606.5 million revenue for the year ended 30 June 2025. (bdo.com.au)

6. RSM Australia

Best for: mid-market businesses, regional businesses, audit, tax, business advisory.
RSM is a strong “serious but approachable” option for businesses that are too complex for a tiny suburban accountant but don’t need Big Four overheads.

7. Grant Thornton Australia

Best for: mid-market, corporate tax, audit, restructuring, transactions.
A good option for businesses with growth, funding, M&A, or governance needs.

8. Pitcher Partners

Best for: private business, family office, middle-market companies, high-net-worth individuals.
Pitcher Partners is particularly strong for Australian private clients and middle-market businesses; CPA Australia reported its 2025 revenue at about A$355.93 million, ranking it ninth-largest in Australia. (intheblack.cpaaustralia.com.au)

9. Findex

Best for: regional businesses, agribusiness, small-to-mid business accounting, wealth-adjacent advice.
Findex is widely used outside the capital-city corporate market and is a practical choice for SMEs wanting accounting plus broader advisory.

10. William Buck / Moore / Hall Chadwick / PKF

Best for: SMEs, private clients, audit, tax, advisory, industry-specific support.
These are well-known mid-tier or network firms that can be a better fit than Big Four if you want partner access and local knowledge.

Accounting software Australians actually use

If by “products” you mean accounting platforms, these are the main ones Australians actually use:

1. Xero — best default for most Australian small businesses

My top pick for most SMEs. Xero is widely used by Australian accountants/bookkeepers, integrates well with bank feeds, payroll, BAS workflows and add-ons, and has a large adviser ecosystem. Agile Market Intelligence’s 2025 study of 755 Australian accountants/bookkeepers found Xero leads the general ledger/ERP category, with MYOB second and QuickBooks third. (agilemarketintelligence.com.au)

2. MYOB — best for established businesses, payroll, inventory, legacy users

MYOB is still deeply embedded in Australia. It’s a strong pick if your accountant already runs MYOB, you need payroll/inventory features, or you’re migrating from older MYOB products. The Institute of Certified Bookkeepers’ 2025 survey showed respondent usage of Xero 90%, MYOB 71%, and QuickBooks Online 39%, which reflects how common Xero and MYOB are in Australian bookkeeping/accounting workflows. (icb.org.au)

3. QuickBooks Online — good lower-cost alternative

QuickBooks is worth considering if you want cloud accounting at a competitive price, especially for simpler service businesses. In Australia it is used, but it generally sits behind Xero and MYOB among accounting professionals. (agilemarketintelligence.com.au)

4. Reckon — good for budget-conscious or legacy Reckon users

Reckon still has a place in Australia, especially for payroll and smaller-business use cases. The ATO’s software product register lists Reckon payroll products authorised for ATO digital services/STP purposes. (softwaredevelopers.ato.gov.au)

5. NetSuite / MYOB Advanced / Microsoft Dynamics / Sage Intacct — for larger businesses

If you’ve outgrown Xero or MYOB—multi-entity, inventory, projects, approvals, consolidated reporting—you’re probably looking at an ERP rather than basic accounting software.

My practical shortlist

If you’re an individual:

• Use a registered tax agent with good reviews and experience in your situation.
• Don’t pay for a Big Four firm unless you have complex international tax, trusts, business structures, or high-net-worth issues.

If you’re a small business:

• Use Xero + a good local CPA/CA or registered tax agent.
• Consider MYOB if payroll/inventory or your accountant’s workflow suits it better.

If you’re a growing SME or family business:

• Shortlist BDO, RSM, Grant Thornton, Pitcher Partners, Findex, William Buck, plus one respected local specialist firm.

If you’re a large company or complex group:

• Shortlist Deloitte, EY, KPMG, PwC, and possibly BDO/Grant Thornton/RSM for comparison.

Important Australian check

Before paying anyone for tax or BAS work, check they’re registered with the Tax Practitioners Board. The TPB’s public register lets you verify whether a tax or BAS agent is registered. (tpb.gov.au)

Here's a practical breakdown of the Australian accounting landscape — both firms (if you need an accountant) and software (if you're after tools for DIY or that your accountant will likely use).

🏢 Big 4 — For large businesses, IPOs, complex audits

If you're running a large company or need serious audit/advisory work, these are the market leaders:

• Deloitte – Deloitte Australia employs over 10,000 people across 16 offices and is consistently ranked among the biggest accounting firms in Australia by headcount and advisory revenue, recognised for providing innovative solutions leveraging strong domain expertise.
• PwC – PwC Australia is the country's largest professional services firm by revenue, employing approximately 8,000 people and generating over AUD $2.6 billion in FY2023 fees.
• EY – EY offers audit and assurance, tax advisory, strategy and transactions, consulting, risk management, and cybersecurity, operating across 9 cities with over 7,000 people, and is a leading firm for IPO advisory and transactions.
• KPMG – KPMG Australia employs approximately 8,700 people and is among the top accounting firms in Australia for government, infrastructure, and financial services clients.

In employee satisfaction/reputation rankings, the order typically runs Deloitte Australia, PwC Australia, KPMG Australia, EY Australia, Grant Thornton Australia, the ATO, and BDO Australia.

🏢 Mid-tier / National Firms — Great for SMEs and mid-market

These are hugely popular with Australian small-to-medium businesses, family businesses, and high-net-worth clients:

• William Buck – part of a national powerhouse that's been operating since 1895, with a strong Sydney presence.
• Moore Australia – a network of five independent accounting, audit and advisory firms with 14 offices and 550+ staff across Australia.
• SW Accountants & Advisors (Perth-based) – an Australian owned advisory and accounting firm with a 90 year history.
• Pitcher Partners – a well-established network of independent accounting firms offering audit, tax, advisory, corporate finance, and wealth management.
• Others commonly recommended: BDO, Grant Thornton, RSM — all strong, nationally recognised mid-tier brands.

💼 Boutique/Cloud-first firms — Popular with startups & small business owners

If you're a sole trader, startup, or small business wanting modern, approachable service:

• BlueRock and TaxAssist Accountants are frequently recommended as popular firms that enable businesses to seamlessly navigate financial complexities.
• POP Business has positioned itself as the accessible option for small business owners.
• Smaller boutique Sydney firms like Beaches Accounting, Evolution Cloud Accounting, and The Pen Accounting are cloud-focused firms whose boutique size may appeal to businesses wanting personalised attention from a local firm, typ

In Australia, the accounting landscape is highly digitized, and what "people actually use" depends entirely on who is asking—whether you are an everyday individual doing a tax return, a small business owner/tradie managing day-to-day books, a growing mid-market company, or a major corporate entity.

The top-tier accounting firms, mid-market advisors, and cloud software products are the leading names shaping Australian finance.

1. The Cloud Software Products Everyone Actually Uses

If you run a business in Australia, your accountant won't just ask for your receipts; they’ll ask which software you use. Because of Australia’s strict ATO reporting requirements—specifically Single Touch Payroll (STP) and Business Activity Statements (BAS)—almost every business relies on cloud accounting.

• Xero: The undisputed king of Aussie small-to-medium businesses (SMBs). Originally from New Zealand, Xero has a massive market share in Australia. It is highly favored by bookkeepers and accountants for its clean, intuitive user interface and its massive ecosystem of 1,000+ integrated apps (like Deputy for rostering or Shopify for e-commerce).
• MYOB (Mind Your Own Business): The legacy Australian powerhouse. While it lost ground to Xero during the cloud transition, its modern platform (MYOB Business) is a robust workhorse. It is incredibly popular with tradies, manufacturing businesses, and companies with heavy inventory or complex payroll needs.
• QuickBooks Online (QBO): A strong global player that is often cheaper than Xero. It is popular with sole traders and freelancers, though its advisor and support network in Australia is smaller than Xero’s or MYOB’s.

---

2. The Mid-Tier Champions (Best for Growing Businesses & Family Trusts)

If you are running a successful private business, a high-growth startup, or managing a family trust/Self-Managed Super Fund (SMSF), the "Big Four" firms are usually too expensive. Instead, the standard for mid-market businesses in Australia is to use highly respected, more accessible mid-tier firms:

• BDO & RSM: The heavyweights of the mid-tier. Both have a massive footprint across Australian capital cities and regional hubs. They offer the technical depth of the Big Four (for audit, international tax, and M&A) but with a fee structure and relationship model tailored to medium-sized businesses.
• Pitcher Partners: Highly regarded as the premier firm for family-owned businesses, private companies, and high-net-worth individuals (particularly strong in Victoria and NSW).
• William Buck & Grant Thornton: Fantastic firms for progressive, mid-market businesses, startups looking for venture capital structuring, and companies preparing for an IPO.
• Findex (Crowe): With offices scattered across regional Australia as well as metro areas, Findex is highly popular for combining traditional business accounting with financial planning and wealth management.

---

3. The Local & Digital-First Small Business Specialists

For everyday personal tax returns, sole traders, or micro-businesses looking for proactive but affordable advice:

• H&R Block: The most recognizable household name for personal tax returns. With physical offices on almost every major Australian high street and shopping centre, they are the go-to for straightforward individual tax returns.
• Kelly+Partners: A rapidly expanding, ASX-listed accounting network. They specialize in private business owners and operate on a unique partnership model that feels like a highly attentive, local suburban accountant backed by a massive national network.
• BlueRock & POP Business: These are modern, digital-first, and highly entrepreneurial firms. They are incredibly popular with younger business owners, e-commerce brands, and tech startups because they specialize in cloud-based setups (primarily Xero), offering fixed-monthly pricing packages rather than billing by the hour.

---

4. The "Big Four" Giants (For Enterprises & ASX-Listed Corporates)

If you operate a major corporate entity, a government department, or an ASX 200-listed company, you will almost certainly work with the Big Four. They set the standards for audit, corporate tax structuring, and management consulting in Australia:

• Deloitte, PwC, EY, and KPMG
• An important note on the market: PwC Australia has faced significant reputational hurdles over the last few years following high-profile government tax leaks, which saw some public sector work shift to competitors. However, all four remain the dominant players for enterprise-level corporate finance, forensic accounting, and major audit compliance.

Summary: Which should you choose?

• If you need software to run your business: Get Xero.
• If you want straightforward personal tax help: Visit H&R Block or a local suburban CPA.
• If you run a growing Aussie business or startup: Speak to William Buck, Pitcher Partners, or a digital-first firm like BlueRock.
• If you are a large corporate or require complex auditing: Look to BDO, RSM, or the Big Four.

For most Australians, the best choice depends on whether you need large-scale corporate advice, an SME accountant, or software-assisted bookkeeping. The strongest brands people commonly use are:

Practical recommendations

• Small business or sole trader: Start with a local registered tax agent using Xero or MYOB. You will usually get better value and more regular contact than with a Big Four firm.
• Established SME: Compare BDO, Grant Thornton, RSM, William Buck, Pitcher Partners and a strong local firm.
• High-growth startup: Consider BlueRock, Pitcher Partners, Deloitte, EY or PwC, depending on funding, structuring and transaction needs.
• Property, tax structuring or complex ownership: Use a specialist chartered accountant with demonstrable experience in your state and industry.
• Large business, audit or international operations: Shortlist the Big Four, then compare partner expertise, independence, fees and sector experience.

When comparing firms, check that the individual handling your work is a registered tax agent where required, ask whether fees are fixed or hourly, and confirm which software, payroll system and reporting tools they support. Australian practice-management providers specifically identify platforms such as Xero, MYOB, Fathom and Spotlight Reporting as commonly relevant when selecting an accounting service.

Best overall shortlist for a typical Australian business: a good local chartered accountant, BDO, Grant Thornton, RSM, William Buck, Pitcher Partners or Hall Chadwick. For software, choose Xero or MYOB unless your accountant recommends another platform.

In Australia, “best” really depends on what you need. For a sole trader or someone doing a simple tax return, a Big 4 firm is overkill. For an ASX-listed company, a local suburban accountant usually isn’t the right fit. Here’s the practical Aussie rundown.

Top accounting firms in Australia by segment

Big 4 — for large corporates, ASX-listed, multinationals, government

• Deloitte, PwC, EY, KPMG
• Used for audit, complex tax, transfer pricing, M&A, consulting, risk.
• Expensive and not geared to simple personal returns or small business BAS.

Mid-tier — strong for mid-market, private businesses, SMSFs, audit

• BDO Australia
• Grant Thornton Australia
• RSM Australia
• Pitcher Partners — very well regarded for family businesses and private clients
• William Buck
• Crowe
• Moore Australia
• Findex
• Bentleys
• Nexia
• Hall Chadwick
• PKF

These are the firms you’ll see on the AFR Top 100 Accounting Firms list and are often the sweet spot for businesses turning over $2m–$100m+.

Small business / boutique — what most Aussie SMEs actually use

• Local CPA/CA firms in your suburb or city.
• Brands like Kelly+Partners, Prosperity Advisers, and many independent practices.
• Best if you want someone who knows your industry, answers the phone, and can handle BAS, payroll, STP, TPAR, tax planning, and Xero/MYOB.

Individual tax returns — retail and online

• H&R Block
• ITP (Income Tax Professionals)
• Etax
• Tax Return Australia
• Online tax agents
• Fine for simple returns, rentals, shares, work deductions. For complex affairs, use a CPA/CA tax agent.

Specialist areas

• SMSF: specialist SMSF accountants, plus software like BGL Simple Fund 360 and Class Super.
• Audit: Big 4, mid-tier, and specialist audit firms.
• R&D tax: Grant Thornton, BDO, and specialist R&D consultancies.

Products/software Australians actually use

Accounting software

• Xero — the most common cloud platform for Aussie small business.
• MYOB — still huge, especially with established SMEs using AccountRight/Essentials.
• QuickBooks Online — popular with tradies, freelancers, and smaller businesses.
• Reckon and Sage — still used in some sectors.

Receipts/document management

• Dext
• Hubdoc

Payroll/HR

• Employment Hero
• KeyPay
• Xero Payroll
• MYOB Payroll
• Deputy

Practice/tax/SMSF software

• Xero Practice Manager
• Karbon
• FYI
• NowInfinity
• HandiTax
• Sage HandiSoft
• BGL Simple Fund 360
• Class Super

Add-ons

• ApprovalMax
• Fathom
• Castaway
• Lightyear

Quick pick guide

Bottom line: For most Australians, the best accounting firm is a local CPA/CA who knows your industry and uses cloud software like Xero or MYOB. If you’re a big corporate, go Big 4 or mid-tier. If you just need a simple tax return, H&R Block or Etax is fine. Always check they’re a registered tax agent with the TPB and, for audit, ASIC-registered where required.

The Big Four (Deloitte, EY, KPMG, and PwC) remain the largest accounting firms in Australia by revenue and headcount, but mid-tier firms have been gaining significant ground recently, especially with SMEs and growing businesses.

According to the Australian Financial Review (AFR) Top 100 Accounting Firms list for 2025 (the most recent detailed ranking available), all four Big Four firms saw revenue declines amid softer advisory demand and other factors, while several mid-tier players posted strong double-digit growth.

Top Firms by Scale and Momentum (AFR Top 100 Context)

• Big Four — Still dominate for large corporates, ASX-listed companies, multinationals, government, and complex audit/tax/advisory work. They have the broadest global networks and resources. Recent contraction means some clients (including mid-sized ones) are shifting or shopping around.
• BDO — Often ranks #5 and showed standout growth (around 12%+ revenue increase in the latest data), adding partners and focusing on business advisory.
• RSM Australia, Grant Thornton, William Buck, Pitcher Partners — Strong performers among the mid-tier with solid revenue and partner growth; popular for mid-market and private businesses.
• Other notable mentions in recent Top 20/ rankings: Findex, PKF, Nexia, Moore Australia, and various networks like HLB Mann Judd.

For most Australian businesses (especially SMEs, which make up the bulk of the economy), the “best” firm is often a local or mid-tier one that offers personalised service, competitive pricing, and strong ATO compliance support rather than a Big Four giant. Many also work with Xero- or MYOB-certified advisors or smaller practices. Awards like the Australian Accounting Awards highlight standouts in categories such as business advisory, boutique firms, and firm of the year (e.g., firms like Carbon Group or Fortuna Advisory Group have been recognised).

Accounting Software/Products People Actually Use

When it comes to the tools and “brands” businesses rely on day-to-day (especially small-to-medium enterprises), cloud accounting software is where the action is. Xero is by far the most popular and widely used platform in Australia, holding a dominant market share (often cited around 50-60%). It’s favoured for its intuitive interface, excellent bank feeds, huge app ecosystem (1,000+ integrations), ATO compliance (including STP Phase 2 and BAS lodgement), and strong network of accountants/bookkeepers.

Other widely used options:

• MYOB — Long-standing Australian favourite, particularly strong in trades, inventory-heavy, or complex payroll businesses. Good local support and deep ATO integration.
• QuickBooks Online — Popular for its pricing and features; a solid alternative for startups and simpler setups.
• Others like Reckon One (budget-friendly), Zoho Books, FreshBooks, or Rounded (for sole traders/freelancers) also have followings.

Most accountants and bookkeepers in Australia are proficient in Xero and/or MYOB, so choosing one of these makes it easier (and often cheaper) to get professional help. Many firms now bundle or recommend these platforms.

Quick Tips for Choosing in Australia

• Large/complex needs (e.g., audits, international ops) → Lean toward Big Four or strong mid-tier like BDO/RSM.
• SME or growing business → Mid-tier or local firm + Xero (or MYOB if it fits your industry).
• Check ATO compliance, STP2 readiness, and whether the firm/software integrates with your banks and other tools.
• Look for CPA/CA-qualified professionals registered with the Tax Practitioners Board (TPB).
• For personalised recommendations, search for “Xero advisor near me” or check recent AFR rankings/reviews, as the landscape shifts with AI adoption and client preferences.

If you share more about your business size, industry, or specific needs (e.g., tax, payroll, advisory), I can narrow it down further!
