Insights

Growth Opportunity Mergers and acquisitions activity is highlighted by the TC Group merger in 2025, signaling a growing demand for integration advisory, due diligence, and post-deal accounting support to scale senior advisory services.

SMB Advisory With a small team and revenue under 1M, Leonherman represents a classic target for outsourced finance leadership (FD services) and scalable advisory packages to drive growth, efficiency, and board-level reporting for owner-managed businesses.

Service Expansion Their broad service mix from real-time bookkeeping to outsourced FD, tax, audit and advisory creates cross-sell potential to clients seeking a one-stop shop for strategy, compliance, and financial operations during growth or transition.

Tech Enablement Existing tech stack (Google Cloud, WordPress, analytics tools) offers a foundation to upsell data-driven reporting, KPI dashboards, and cloud-based advisory platforms to differentiate in a competitive market.

Client Loyalty High client retention suggests opportunities to formalize scalable retainer-based advisory programs, such as ongoing M&A readiness, due diligence coaching, and periodic financial health reviews for long-term value.
