Get executive-level financial expertise — without the full-time overhead. At Orsak Langner & Barthel PLLC, we offer flexible, part-time Controller and CFO services to help Texas businesses and nonprofits improve financial visibility, make confident decisions, and build scalable systems for long-term success.

Most small to mid-size organizations don’t need a full-time CFO — but they still face big financial decisions. From managing growth and cash flow to preparing for investors or audits, our part-time Controller/CFO services fill that leadership gap with expert guidance tailored to your size and needs.

We help clients:

• Create and manage budgets, forecasts, and cash flow models
• Review and present financial statements to stakeholders
• Guide strategic decisions around expansion, financing, or investment
• Oversee internal controls, policies, and reporting processes
• Act as liaison with bankers, auditors, and board members

Whether you're a growing business, a mission-driven nonprofit, or a founder juggling too many financial responsibilities, we provide the insight and structure to help you operate with confidence.

• Privately held businesses experiencing rapid growth or operational complexity
• Nonprofits that need strategic oversight but can’t justify a full-time CFO
• Family offices or real estate firms managing multiple entities or large capital projects
• Entrepreneurs and owners seeking to elevate financial strategy and reporting

With Orsak CPAs, you gain an experienced financial leader — on your terms and your timeline.
