About Marcus Flynn Accounting & AdvisoryMarcus Flynn, CPA

Founder | Financial Systems Architect | Advisor to Business Owners

Welcome. I’m Marcus Flynn

I’m a Certified Public Accountant who helps business owners and executives build financial systems that create clarity, control, and confident decision-making.

Marcus Flynn Accounting & Advisory was founded on a simple idea:

Most businesses don’t have accounting problems.
They have structure problems that show up in their accounting.

I don’t just prepare reports. I design the financial framework that makes those reports meaningful.

With more than 15 years in the accounting profession, my work centers on helping clients move from:

  • Messy books → clean systems
  • Reactive tax filing → proactive tax strategy
  • Confusion → financial visibility
  • Guesswork → informed decisions

What I Actually Do for ClientsI partner with clients to:

Many clients come to me because their numbers are technically “done”… but they still don’t understand what’s happening in their business.

That’s where I come in. 

Who I Work Best With

I work best with:

  • Small business owners who want control over their numbers
  • Executives who need dependable financial oversight
  • Entrepreneurs tired of disorganized books and tax surprises
  • Clients who value clarity, responsiveness, and straight answers

If you want a call center, I’m not your firm.
If you want a CPA you can talk to directly who understands your business, we’ll work well together.

I graduated from Bellarmine University and built my career in financial accounting, system design, and executive advisory.

A Personal Note

I believe good accounting reduces stress.
Great accounting gives you confidence.
