Mark A Stiles CPA, PLLC
MASCPA is a modern, virtual CPA firm specializing in fractional CFO services, strategic bookkeeping, and tax planning for growth-focused small businesses.
Rooted in our proprietary Box Method, we help business owners build a stable, scalable financial foundation by ensuring that every critical side of their “business box” — Operations, Marketing & Sales, Finance & Strategy, and People & Leadership — is fortified with clear systems and practical insight.

We go beyond compliance: MASCPA acts as your strategic partner, combining sage-level expertise with an approachable, down-to-earth style. From day-to-day bookkeeping to proactive tax strategy and high-level financial forecasting, we deliver clarity, consistency, and confidence so you can stop operating in the dark and start leading with presence.

Our mission: To demystify accounting, amplify your decision-making power, and protect your business legacy — one system, one SOP, one conversation at a time.

Services include: Fractional CFO, strategic bookkeeping, tax planning and preparation, WIP and job costing advisory (for construction and trades), and financial systems implementation.

If you’re ready to fill your box, strengthen your cash flow, and scale with integrity, MASCPA is your trusted guide.

Clients who would be a good fit

Our ideal client is a growth-minded small business owner often in construction, professional services, retail/e-commerce or trade who’s ready to stop guessing about their numbers and start leading with clarity.
They value integrity, want clean systems, and know they’ve outgrown DIY bookkeeping or a generalist accountant. They’re not looking for just tax prep, they want a proactive partner to build a strong financial foundation, manage cash flow wisely, implement real job costing or WIP reporting (when relevant), and make smarter, data-backed decisions.

They care about legacy, their team, and doing things the right way and they’re ready to invest in a relationship with an advisor who cares just as much about their success as they do.

Clients who wouldNOTbe a good fit

If you see your accountant as a once-a-year tax filer instead of a strategic partner; we’re probably not for you.
If you’re unwilling to follow systems, share information on time, or adopt the right tools; you’ll fight the very structure that protects your business box.

If you want to cut corners, hide income, or bend the rules; respectfully, we’re not your firm.

And if you just want “cheap and fast”, there are plenty of cookie-cutter tax shops for that. We’re here for owners who care about clarity, integrity, and building something that lasts.
