M&A for professional services facing succession and consolidation.

Australian professional services is being reshaped by two converging forces: a generational succession event in legal, accounting and consulting, and active consolidation by mid-tier firms, holding companies, and PE platforms across wealth management, insurance brokerage, and agency networks. Novastrone advises professional services owners and acquirers through these moments — where partner relationships, brand equity, and client trust all have to survive the transition intact.

03 · Value drivers

What buyers actually pay for.

In professional services, the line between the firm and the people is the firm. Buyers pay for the things that survive the partner walking out the door.

  • Recurring or repeatable revenue — retainers, panel appointments, ongoing engagements
  • Partner and fee-earner productivity and leverage
  • Client diversification — no single client > 15–20% of revenue
  • Brand strength in a defined niche
  • Tech stack and IP — especially in consulting and marketing
  • Tenure and retention of fee-earners and partners
Specialist or recurring-revenue models command the premium — generalist practices sit at the lower end. The specialist premium
04 · Mechanics

Common structures, and the traps that come with them.

Earn-outs are universal in this sector — the structure of the earn-out is where the deal is actually won or lost.

  • Earn-outs are almost universal (24–36 months tied to retention and revenue).
  • Equity rollover and partner buy-in structures are common.
  • Vendor finance for partner-track buy-outs.
  • Restraint of trade and non-compete clauses are material to value.
  • Multi-stage earn-outs tied to specific revenue or client retention milestones.
Key-person risk where the founder is the rainmaker is the defining structural challenge in this sector.
  • Key-person risk where the founder is the rainmaker.
  • WIP and accrued income valuation disputes.
  • Client losses during transitionclients who stay because of one specific partner.
  • Trust account or regulatory exposure (legal and financial advice).
  • Pre-existing professional indemnity claim exposure.
