How Our Fixed-Fee Engagements Work

Clarity, Trust & True Value

Why Melbourne Businesses Choose Fixed-Fee Accounting

You know the fee before any work starts, and what it covers.

Every engagement starts with a written proposal. It sets out the work included, the fixed fee and how often it is billed, so you can plan the cost for the year.

Recurring services, such as bookkeeping, BAS lodgements, year-end financial statements and tax returns, are priced as a fixed monthly or annual fee. Projects, such as a restructure, a business purchase or a response to an ATO review, are quoted separately. We confirm the fee for any work outside the agreed scope, and you approve it before we start.

Third-party costs, such as ASIC lodgement fees, are shown separately in the proposal. We review the scope with you as your business changes, rather than billing for each call or email.

How it works

  1. Introductory meeting. 30 minutes, online or at our Chadstone or Moorabbin office, at no charge.
  2. Written proposal. The agreed scope and fixed fee, in writing.
  3. Onboarding and ongoing support. Identity verification, ATO agent linking and Xero access, then a primary CPA contact for the year.

Changing accountants? We contact your previous accountant and arrange the handover of your records, so you do not have to. See how switching to 42 Advisory works.

Recent Engagements

Civil Contractor: Valuation and Sale Readiness

A founder-led civil contractor wanted an indicative value ahead of a possible sale. We normalised three years of EBITDA, separated the plant entity at commercial lease rates and modelled a realistic deal structure. The result was an enterprise value range of about $35–47 million, with a 12-month sale-readiness roadmap.

Fitness Group: Management Equity

A subscription fitness business needed a market value so key managers could become shareholders. We assessed maintainable earnings from recurring memberships and concluded an equity value of about $3.8 million on a cash-free, debt-free basis.

Straight Answers, Real Transparency

Frequently Asked Questions About Accounting & Tax Services in Melbourne

Answers to the questions Melbourne business owners ask most about our fees, switching accountants and getting started. Last reviewed: September 2026.
How much does an accountant cost for a small business?

Fees depend on the scope of work, the entities involved and how complex your affairs are, so we do not publish a single price.

After a 30-minute introductory meeting at no charge, we send you a written proposal with the scope and a fixed fee. Recurring work is billed monthly or annually. Projects are quoted separately, and you approve any change before work starts.

Read more about fixed fees and hourly billing

How does fixed-fee accounting work?

Fixed-fee accounting means you pay a set monthly or annual fee, agreed upfront, rather than being billed by the hour.

At 42 Advisory, fees are based on the scope and complexity of your business, not the time spent responding to questions. This allows you to contact us when needed, plan costs with certainty, and avoid unexpected invoices.

The scope is reviewed regularly to ensure the service remains appropriate as your business changes. Read more about fixed fees vs hourly rate

What is included in the fixed fee, and what costs extra?

The proposal lists every service included, such as bookkeeping, BAS lodgements, financial statements, tax returns and scheduled advisory meetings.

Work outside that list, such as an ATO audit, a restructure or a business acquisition, is quoted separately. Third-party costs, such as ASIC fees, are shown separately. You approve any additional fee before we start.

How do I switch accountants to 42 Advisory?

You do not need to contact your current accountant. Once you accept our proposal, we complete identity verification, link your ATO record to us as your tax agent and request your records from your previous accountant under the professional ethical clearance process.

Your ATO lodgement history stays intact. See the full switching process.

How long is the introductory meeting?

The introductory meeting is typically 30 minutes, online or at our Chadstone or Moorabbin office, and there is no charge.

We discuss your business, your current accounting and tax position, and the support you may need. It is not formal advice. If we are the right fit, we outline the next steps.

What happens after the introductory meeting?

If we are the right fit, we send you a written proposal with the agreed scope and fixed fee. There is no obligation to proceed. Once you accept, we begin onboarding and assign you a primary CPA contact.

What does a business accountant do for small businesses?

A business accountant keeps your tax, BAS and financial reporting compliant, and helps you plan. At 42 Advisory, that includes tax planning before year-end, cash flow forecasting and regular reviews of how the business is performing.

See how 3-way forecasting supports growth

How do I choose the right accountant for my business?

Look for:

  • A registered tax agent and CPA-qualified advisers
  • A written scope and fee before work starts
  • Experience with businesses like yours and with cloud accounting software
  • Planning and advice during the year, not only at lodgement time

You can check a tax agent's registration on the Tax Practitioners Board public register.

What does a Virtual CFO service include?

A Virtual CFO service provides senior financial oversight without the cost of a full-time CFO.

At 42 Advisory, our Virtual CFO service typically includes 3-way financial forecasting (profit & loss, balance sheet, and cash flow), scenario modelling, budgeting, and performance reporting. We help you understand how today’s decisions affect future cash flow, profitability, and financial position.

The service is advisory-led and tailored to your business stage — whether you’re planning growth, managing cash flow, preparing for funding, or improving margins.
