The Main Street CPA, built for today

We’re the CPA firm Main Street used to have: we know you by name, pick up when you call, and sit down with you in person when we can. And because we’re a modern firm built on today’s tools, less of our time goes to paperwork and more of it goes to you.

Know You by Name

A licensed CPA who knows you, your business, and your story, year after year.

Call or Text Us

You always connect with your CPA, who already knows your situation. No getting rerouted to junior staff or outsourced personnel.

Meet in Person

Over coffee, at our Charlotte office, or at your place of business when we can.

Built on Today’s Tools

Professional-grade tax software, cloud accounting, and automated workflows handle the routine work, so our time goes to strategy.
What you get

Full-service CPAs. A focus on tax strategy.

We act as your proactive tax strategist, working alongside your other advisors throughout the year, with the same team preparing your returns, so nothing falls through the cracks.

Tax is our focus, but it’s not all we do. Quarterly or year-end financials, loan packages, cost segregation studies, and more are there whenever you need them.
Included in every engagement

Clear fees. Ongoing support.

One fixed fee, agreed upfront in writing, and a CPA you can reach whenever you need one.

Your Tax Returns

Business and owner returns prepared and filed by a licensed CPA, with a clear explanation of what we're seeing and recommendations for the year ahead.

Meetings Throughout the Year

We meet with you multiple times a year to plan ahead — estimated payments, year-end moves, and big decisions — so the proactive moves happen before deadlines, not after.

Advisory Hours

Call or email with questions as they come up without getting a bill. If something grows into its own project, we scope it with you before any work begins.

Audit Support

If a return we prepared is examined, audit support is included for three years after filing. Larger matters are scoped separately.
How it works

We scope it right from the start

Before we quote anything, we review your actual returns and records, so your fixed fee reflects your real situation.

Step 1

Intro Call

A conversation about you, your business, and what's on your mind.
Step 2

Diagnostic Review

We request prior-year returns and anything else we need, and a CPA reviews them for errors, missed strategies, and structure issues.
Step 3

Fixed-Fee Proposal

After we have your documents, you get our findings and a fixed-fee proposal for the work ahead.
Step 4

Foundation, Then Year-Round

We complete the foundational work, meet with you throughout the year, and prepare your return.
Your first year usually starts with foundational work: fixing what’s been missed in the past, putting new strategies in place, and streamlining how the business runs day to day.
Who we serve

Main Street businesses, and the people who own them

Owner-led businesses across the Carolinas, along with individuals and families whose finances have outgrown a once-a-year preparer, and trusts and the fiduciaries who manage them
