McAdam Siemon Business Advisors

What McAdam Siemon Business Advisors does

McAdam Siemon Business Advisors (legal entity: McAdam Siemon Pty Ltd) is an Australian accounting and business advisory firm headquartered in Upper Mt Gravatt, Queensland, founded in 1996 by Rob McAdam and John Siemon. The firm serves small and medium enterprises, business owners and individuals across Brisbane and the Sunshine Coast through three offices (Upper Mt Gravatt headquarters, Forest Glen, and a by-appointment Noosaville office), with co-founders and partners John Siemon, Sam Hodgetts (Partner since 2010) and Peter O'Rielley each bringing 25-30+ years of experience. Its core offerings group into four general services — External CFO, Business Improvement (accounting and advisory), Tax & Compliance, and Bookkeeping — and six expert verticals: Business Valuations & Improvement, Management Rights, Motels & Accommodation, Online Businesses, SMSF Administration (via wholly-owned SmartChoice), and Wealth Management (via the McAdam Siemon Wealth Management JV with McGregor Wealth Management). All bookkeeping services are delivered via The Bookkeeping Collective, a wholly-owned sister company focused on cloud-based, Xero-integrated bookkeeping, training, and system implementation.

The firm's technology stack is built around the Xero platform (Gold Partner status) with plug-ins for web-based shopping carts and stock control systems, supporting its online-business and management rights workflows. It does not disclose proprietary software, models, or AI/ML capabilities; the client portal is provided by a third-party (Hownow HQ). Revenue is generated primarily through subscription-style recurring engagements (annual tax and compliance with fixed-price upfront quoting and 12-month monthly payment plans), external CFO retainers, SMSF administration subscriptions, wealth management fees via the JV, and project-based professional services such as business valuations and transaction support. Go-to-market is consultative and direct: phone-led (1300 003 421), website enquiry forms, content marketing via news articles and the MSBA newsletter, and industry referrals — particularly within the management rights and accommodation sectors.

The business is privately held with no institutional investors, no parent company, and no disclosed funding rounds or M&A activity. The firm has been recognised as Accountant of the Year at the accommodation industry's leading awards for two consecutive years and was a 2025 ARAMA Management Rights Industry Top Awards finalist for The People's Choice Service Provider of the Year, underscoring its positioning within niche Queensland verticals rather than as a generalist scale player.
