Tailored CPA Services for Attorneys, Consultants, Agencies, and Professional Firms


Orsak CPAs supports professional service firms in Houston, Texas—including law, consulting, and design practices—with precise accounting, tax, and advisory services. We help service businesses strengthen financial systems, reduce tax burdens, and focus on growth.

Professional service firms — from law offices to marketing agencies and IT consultants — operate on trust, reputation, and billable hours. But behind that expertise is a business that still needs solid financial systems, accurate reporting, and proactive tax strategy. At Orsak CPAs, we help service-based businesses across Texas focus on what they do best, while we handle the financials that keep things running smoothly.

Whether you’re a solo attorney, managing a small creative agency, or scaling a multi-partner consulting firm, we provide specialized accounting and advisory services to support your growth, protect your compliance, and optimize your earnings.

Serving a Wide Range of Professionals and Firms


We work with:

  • Legal and accounting practices
  • Marketing and design agencies
  • IT and business consultants
  • Engineering and architectural firms
  • Private practices and freelance professionals

Our services are designed to help you track revenue by client or project, manage subcontractor payments, reduce tax liability, and keep your business in good standing with Texas and federal agencies.

Built for High-Skill, Low-Asset Businesses


Unlike retail or manufacturing, professional service firms often don’t deal with inventory or equipment-heavy operations. Your value lies in your people, your ideas, and your client relationships — and your accounting should reflect that.

We help service firms:

  • Track income by retainer, hourly billing, or project milestones
  • Manage contractor and employee payrolls
  • Stay compliant with 1099 filings and reasonable compensation rules
  • Forecast revenue and overhead for sustainable growth

Whether your firm is scaling up or streamlining, we tailor our services to fit your size, stage, and specialization.

Financial Simplicity for Complex, Client-Facing Work


Professional service firms live by relationships and reputation — but success also hinges on smart business systems. From tracking time and invoicing clients to managing contractor payments and forecasting revenue, it’s critical to have financial infrastructure that supports your expertise. At Orsak CPAs, we help Texas-based professionals stay organized, compliant, and profitable.

Whether you run a boutique law firm or manage a remote-first creative agency, we provide tailored support that reflects your billing model, staffing setup, and long-term goals.

Flexible Support for Flexible Business Models


Professional service firms often operate across a mix of:

  • Hourly, retainer, or milestone-based billing
  • W-2 employees and 1099 subcontractors
  • High-income owners needing compensation planning
  • Multiple lines of business or service categories

We help you set up your books to track performance by project, client, or service type — offering real insights into your profitability and cash flow.

We also support:

  • Revenue recognition for retainers or staged project payments
  • Year-end planning for high-earning partners or solo owners
  • Payroll processing for internal teams and contractors
  • Reporting for banks, grantors, or investors (when applicable)

Clear Reporting for Confident Decision-Making


We don’t just handle compliance — we help you build a business around your expertise. Whether you're expanding, hiring, or preparing for succession, we offer:

  • Cash flow forecasting for cyclical income
  • Monthly or quarterly reporting for internal use
  • Financial statement preparation for banks or strategic planning
  • Oversight of bookkeeping and accounts payable functions

Many of our clients start small and grow into needing more structure — and we scale our services accordingly, from hands-on advisory to CFO-level support.

Built for Solo Pros and Multi-Partner Firms Alike


Whether you’re a one-person consultancy or a growing firm with multiple partners, we adapt our services to your structure. We assist with:

  • Profit allocation for partners and member-owners
  • Reasonable salary analysis for S-Corp owners
  • Multi-entity structure for growing client segments or spin-offs
  • Succession and exit planning for senior professionals

You bring the expertise — we bring the structure that helps you build a business around it.
