EDUCATION

UTA Dallas CPA Firm Member

Over a decade in tax compliance, international tax, and real estate accounting has taught me one thing: clarity is key. Before founding SDO CPA, I sharpened my skills at top firms like EY and BDO—managing multi-state, partnership, and S-Corp filings. Now, as Managing Partner, I focus on simplifying complex tax laws, automating day-to-day financial tasks, and offering forward-thinking advice so Dallas businesses stay competitive in a fast-paced marketplace. My ultimate goal? Empowering you with data-driven insights to maximize growth and confidently control your financial future.

Frequently Asked Questions

How much does a CPA cost for a business in Dallas?

PA fees vary based on your business complexity, transaction volume, and service needs. At SDO CPA, basic bookkeeping starts around $300–$500 per month for a single entity. Full-service packages that include bookkeeping, tax planning, and advisory typically range from $1,000–$2,000 per month. Dallas businesses with complex operations or multiple entities may require custom pricing.

Do you work with Dallas-based startups and tech companies?

Yes. Dallas is home to a thriving startup ecosystem and major tech employers. We help technology companies with R&D tax credits, equity compensation planning, SaaS revenue recognition, and investor-ready financials.

Can you help with multi-state tax compliance for Dallas businesses?

Absolutely. Many Dallas companies operate across state lines. We help navigate nexus requirements, apportionment rules, and multi-state filing obligations to keep you compliant and minimize your tax burden.

Do you work with professional services firms in Dallas?

Yes. Professional services—including law firms, consulting firms, and marketing agencies—are a core part of the Dallas economy. We understand partner compensation structures, client billing reconciliation, and the unique tax planning needs of service businesses.

What's the difference between a bookkeeper and a CPA?

A bookkeeper records daily transactions and maintains your financial records. A CPA is a licensed professional who can prepare and sign tax returns, provide tax planning advice, represent you before the IRS, and offer strategic financial guidance.

Can you work with my existing QuickBooks or accounting software?

Yes. We work with QuickBooks Online, Xero, FreshBooks, and other cloud-based platforms. We also integrate with payroll platforms like Gusto and expense tools like Ramp.

Do you offer fractional CFO services in Dallas?

Yes. Our fractional CFO services provide cash flow forecasting, budgeting, financial modeling, and strategic planning support—ideal for Dallas businesses that need financial leadership without a full-time hire.
