Brentnalls WA

What Brentnalls WA does

Brentnalls WA (legal entity: Brentnalls Management Services (WA) Pty Ltd, ACN 613 295 480) is a privately held chartered accounting and business advisory firm headquartered in Mount Hawthorn, Perth, Western Australia, operating under a sales-led go-to-market model that targets established owner-managed businesses across Western Australia. The firm was founded in 1993 by Tony Monisse, who remains a director alongside Managing Director Chris Mandzufas and Director Chris Smith, and operates with a headcount of 17 employees. It is a registered Tax Agent (TAN 25491624) and operates under the Tax Agent Services Act 2009.

The firm runs a multi-service delivery model built around four core offerings: Business Advisory (anchored by structured Quarterly Business Review meetings and exit and succession planning), Accounting and Taxation compliance, Tax Advisory, and an add-on Wealth Services module. Underlying the advisory work is a proprietary methodology productised through four diagnostic tools — the Change Success Diagnostic, Growth and Profit Solutions Business Diagnostic, Business Scale Up Diagnostic, and Value Builder Questionnaire — supported by the proprietary Blue Ocean Game Plan client portal used for document collaboration. Technology stack consists of Xero and MYOB as cloud accounting platforms, with no mobile app or public API offering.

Revenue is generated entirely through professional services fees, structured as ongoing advisory retainer arrangements or project-based engagements; pricing is not publicly disclosed. Customer acquisition combines direct engagement via strategy sessions, professional adviser referrals (lawyers, finance brokers, financial planners, business coaches), Mindshop workshops, and the Business Growth Network (BGN) peer community. The firm is a member of the Brentnalls National Alliance, which historically ranked 34th in the BRW Top 100 accounting firms and provides a national cross-referral channel beyond the WA core market. Client concentration is distributed across multiple industries (Mining Services, Construction and Earth Moving, Building Materials, Professional Services, Engineering and Fabrication, ICT, Automotive), with named long-tenured case study clients including Action Glass & Aluminium, Austim, and Ledge Finance.
