Marie spent nineteen years as a management accountant for a mid-sized manufacturing firm in Dandenong, closing the books every month with the kind of quiet precision that made her indispensable — until the day the finance team was told that a cloud reconciliation platform and two remaining analysts could do the work of eight. She was one of the six who were let go. What that software couldn’t replicate, though, was the thing Marie’s clients had always valued most about her: the ability to sit across the table from a stressed small business owner, translate a wall of numbers into a plain-English decision, and say “here’s what I’d do” with the calm authority of someone who has actually lived through a cash flow crunch. Bookkeeping and accounting software has become extraordinarily capable at data entry and reconciliation, but it still can’t read a client’s anxiety, ask the right follow-up question, or take responsibility for a judgement call.

That gap is exactly why a bookkeeping or accounting practice remains one of the most credible small businesses a displaced finance professional can build. Clients aren’t paying for someone to type numbers into Xero — they’re paying for someone who understands their business, keeps them out of trouble with the ATO, and tells them the truth about their numbers. This guide walks through what it actually takes to set up a bookkeeping or accounting practice in Australia, from registration and insurance through to your first ninety days of trading.

What Does It Take to Start a Bookkeeping or Accounting Business?

The qualifications you need depend heavily on what services you plan to offer. If you intend to prepare and lodge Business Activity Statements (BAS) or provide GST and payroll advice on behalf of clients, you must register as a BAS Agent with the Tax Practitioners Board (TPB). That registration requires a Certificate IV in Accounting and Bookkeeping (or higher), a minimum number of hours of relevant experience under the supervision of a registered agent, and ongoing continuing professional education. If you want to prepare and lodge income tax returns, you’ll need to register as a Tax Agent, which has a higher bar — generally a relevant tertiary qualification (an accounting degree is the common path), along with the required supervised experience and, in many cases, membership of a recognised professional body.

If you’re a qualified accountant, joining CPA Australia, Chartered Accountants Australia and New Zealand (CA ANZ), or the Institute of Public Accountants (IPA) will strengthen your credibility and, depending on the body, may be a pathway requirement for tax agent registration. Beyond the paperwork, the trade itself demands obsessive attention to detail, comfort with ambiguity (clients rarely present their records in a tidy state), and the emotional steadiness to deliver bad news — a looming tax bill, a cash flow problem — without the client feeling judged.

Setting Up the Business

Start by registering for an Australian Business Number (ABN) through the Australian Business Register. Most solo bookkeepers begin as sole traders because it’s simple and cheap to set up, though many later move to a company structure once revenue and liability exposure grow — a company can offer asset protection and a cleaner path if you plan to bring on staff or a business partner. Talk to your own accountant about which structure suits your situation before you lodge anything.

You’ll need to register your BAS or Tax Agent status with the TPB before you can legally charge fees for that work — operating unregistered is a serious compliance breach. Register your business name with ASIC if you’re trading under something other than your own name, and make sure your software (Xero, MYOB or QuickBooks Online are the common choices) is set up with proper client file security. Professional indemnity insurance is essential — it protects you if a client claims your advice caused them financial loss — and most professional bodies and the TPB effectively require it as a condition of registration. Public liability cover is worth adding if you ever meet clients on-site, and cyber liability insurance is increasingly important given how much sensitive financial data you’ll be holding.

What It Costs to Get Started

Bookkeeping and accounting is one of the leaner businesses to launch because your core asset is your expertise, not equipment. Realistic starting costs include: TPB registration fees (a few hundred dollars, renewed periodically), professional body membership (roughly $500–$900 a year depending on the body and your membership grade), cloud accounting software subscriptions and practice management tools ($100–$400 a month depending on client volume and whether you pay wholesale partner rates), professional indemnity and public liability insurance ($800–$2,500 a year depending on cover level), a decent laptop and dual monitors if you don’t already have them ($1,500–$3,000), and basic branding plus a simple website ($500–$2,500). All up, most people can get a bookkeeping practice trading for somewhere between $4,000 and $10,000, with accounting practices at the higher end if you’re paying for more comprehensive practice management and document automation software from day one.

Finding Your First Customers

Your first clients will overwhelmingly come from people who already trust you — former colleagues, past employers, and your existing network — so don’t be shy about letting people know you’re now available. Set up a Google Business Profile immediately; local searches for “bookkeeper near me” or “BAS agent [suburb]” convert well because tax and compliance work is trust-driven and local. Build referral relationships with commercial accountants (if you’re a bookkeeper, accountants are a natural referral source for overflow work), business coaches, mortgage brokers, and solicitors who deal with small business clients — these professionals constantly meet business owners who need a bookkeeper and don’t want the liability of recommending someone unvetted. LinkedIn is genuinely useful in this trade: share plain-English content about BAS deadlines, single touch payroll changes, or common deduction mistakes, and you’ll build authority with the exact audience of small business owners who are searching for help. Local business networking groups, chamber of commerce events, and industry associations for trades you specialise in (hospitality, construction, allied health) are also strong sources of warm referrals.

Common Mistakes First-Time Owners Make

  • Undercharging out of fear of losing clients, which locks you into unsustainable margins and attracts clients who don’t value the work — price for the value and risk you’re taking on, not just the hours.
  • Taking on clients outside your registration scope, such as lodging tax returns without being a registered tax agent, which exposes both you and the client to serious compliance risk.
  • Failing to set clear engagement terms and scope, leading to scope creep where “bookkeeping” quietly expands into unpaid business advice, debt collection, and after-hours phone calls.
  • Neglecting their own compliance obligations — BAS agents and tax agents must keep their own CPE hours, insurance, and TPB registration current, and it’s easy to let this slip once you’re busy serving clients.

Your First 90 Days

Weeks 1–2: finalise your ABN, business structure, TPB registration application (if not already registered), professional indemnity insurance, and your core software stack. Set up your Google Business Profile and a simple one-page website explaining your services and who you work with.

Weeks 3–4: reach out personally to your entire professional network — former colleagues, past managers, family friends who run businesses — and let them know what you’re doing. Ask directly for introductions rather than hoping people remember to think of you.

Weeks 5–8: start building referral relationships with two or three local accountants, a mortgage broker, and a business coach or two. Attend at least one local networking event or chamber of commerce meeting. Take on your first one or two clients, even at a slightly discounted “founding client” rate, to build case studies and testimonials.

Weeks 9–12: formalise your onboarding process and engagement letter template based on what you learned from your first clients. Ask happy clients for a Google review and a referral. Review your pricing based on actual time spent versus what you quoted, and adjust for the next round of clients. By day 90 you should have a repeatable process for onboarding, a small but real client base, and clarity on which niche or industry you want to specialise in.

If this isn’t quite the right fit, GrowOnline’s guides on start a legal practice, consulting business and marketing agency cover similar ground for first-time owners.

Losing a finance role to automation is a genuine blow to confidence, but the skills that made you good at your old job — precision, judgement, the ability to explain numbers to nervous humans — are exactly what small business owners are desperate for and what software still can’t provide. If you’d like a hand with the market research, website, and marketing systems to get your practice in front of the right clients faster, that’s exactly the kind of groundwork GrowOnline helps new practice owners put in place.
