Insights

Construction focus TYS highlights over 60 years of construction market experience and strong relationships with construction bankers and bonding agents, presenting a clear entry point for expanding audit, tax, and advisory services to construction companies and specialty contractors.

Fixed-rate value The firm markets services at fixed rates to guarantee predictable results, which can be leveraged to upsell bundled services (audit, accounting, tax, and advisory) to clients seeking cost certainty and scalable engagements as their businesses grow.

Advisory stance Position TYS as trusted advisors who proactively flag issues and opportunities, offering consultative selling opportunities around process improvements, internal controls, and strategic planning for closely held and family-owned businesses.

Growth potential A smaller but growing firm (~11-50 employees) with plans to add professionals suggests opportunities to target mid-market clients in need of scale, specialty construction expertise, and broader service lines beyond core accounting.

Staff expertise Recent hires and the emphasis on high standards for employees indicate a strong service quality narrative; leverage this to differentiate in competitive bids and to win work requiring seasoned CPA expertise in tax, auditing, and business consulting.
