Texas companies face these challenges in an unusually active business environment. Dallas-Fort Worth, Houston, Austin, and San Antonio support substantial concentrations of technology, energy, manufacturing, healthcare, real estate, financial services, construction, and professional services companies. For a growing mid-market organization, that makes the choice of CPA firm less about finding someone to handle compliance and more about finding expertise that can remain useful as the business changes.
9 CPA Firms Serving Growing Texas Companies
1. Bennett Thrasher
Bennett Thrasher combines audit, tax, and advisory capabilities with a Dallas presence built around the needs of companies navigating transactions and business growth. Its Texas team works with privately held businesses, investors, and portfolio companies across industries including technology and SaaS, manufacturing and distribution, construction, healthcare, professional services, and business services.
That combination is particularly relevant for mid-market businesses because accounting requirements rarely grow in isolation. An acquisition may create financial due diligence, tax structuring, purchase accounting, and post-close reporting needs at the same time. Expansion into additional states can introduce nexus and sales tax obligations. International growth can create new tax and reporting questions.
Bennett Thrasher’s Dallas practice has particular depth in transaction advisory and Quality of Earnings work. Its professionals support buy-side and sell-side transactions, tax diligence, post-close opening balance sheet and purchase price accounting, and related advisory requirements. These capabilities can support both companies pursuing acquisitions and owners preparing for a potential sale.
For a growing Texas company, the value of this breadth is continuity. A business can begin with a specific tax, audit, or transaction requirement and draw on additional specialists as its operations become more complex, without treating every new growth issue as a separate accounting relationship.
2. Whitley Penn
Whitley Penn has unusually deep roots across the Texas market, with established operations in Austin, Dallas, Fort Worth, Houston, and other locations. In 2026, the firm appeared on the largest accounting firm lists published by the business journals serving Austin, Dallas, Houston, and San Antonio, reflecting its substantial presence across the state’s major business centers.
Its services span audit, tax, and advisory, allowing growing businesses to address both recurring financial requirements and more complex events such as transactions, expansion, and organizational change.
For mid-market companies, local scale can matter. A business may begin in North Texas and later add facilities, employees, or operations in Houston, Austin, or San Antonio. Working with a firm that already has professionals across those markets can provide continuity as the company’s footprint changes.
Whitley Penn also serves a broad mix of industries, which is useful in a state where growth companies can look very different from one another. Technology businesses have different accounting and tax priorities from energy companies, manufacturers, real estate organizations, or financial services firms.
3. Weaver
Weaver is headquartered in Houston and maintains a significant presence across Texas, including offices in Austin, Dallas, Fort Worth, Houston, Midland, San Antonio, and The Woodlands. The firm provides audit, tax, and advisory services, combining Texas market knowledge with a broader national practice.
Its experience is particularly relevant to mid-market businesses moving through multiple stages of growth.
Weaver’s private equity practice, for example, supports portfolio companies across the transaction lifecycle. Pre-acquisition services include Quality of Earnings, financial and tax due diligence, transaction structuring, technology due diligence, and data analytics. After a transaction, the firm can assist with purchase accounting, financial transformation, tax remediation, cybersecurity, and integration-related requirements. During the growth cycle, its services extend into financial audits, internal controls, tax structuring, CFO support, and other operational areas.
That lifecycle approach is useful beyond private equity. Many of the same challenges arise when privately held companies make acquisitions, prepare for outside investment, professionalize financial reporting, or build infrastructure for an eventual exit.
4. RSM US
RSM’s positioning is unusually straightforward for this particular list: the firm explicitly focuses on the middle market.
Its Texas practice includes offices in Austin, Dallas, Fort Worth, Houston, and San Antonio, providing audit, tax, and consulting capabilities across the state’s major business markets. RSM describes its middle-market focus as central to its operating model rather than simply one client segment among many.
That focus becomes important when a company reaches the point where standard compliance services are no longer sufficient but its needs still differ from those of the world’s largest public companies.
Growing businesses may need assistance with financial reporting, technology implementation, tax transformation, transaction planning, cybersecurity, risk, international operations, and other projects that require specialists outside the internal finance department.
For companies firmly within the middle market and expecting their accounting needs to become more multidisciplinary, RSM offers a model specifically organized around that stage of business.
5. Forvis Mazars
Forvis Mazars combines a national CPA and advisory platform with a significant Texas footprint. The firm has offices in Dallas, Houston, Austin, San Antonio, and Fort Worth, giving growing companies access to local teams across several of the state’s major commercial centers.
Its Texas offices provide audit, tax, and consulting services across industries including financial services, construction, real estate, manufacturing and distribution, and nonprofit organizations.
For mid-market companies, the breadth becomes particularly useful when growth introduces events that sit outside routine accounting.
M&A is one example. Forvis Mazars maintains transaction advisory capabilities serving private equity groups and corporations, including buy-side and sell-side due diligence, tax due diligence, and transaction structuring. Those services can become relevant whether a Texas company is making its first acquisition, pursuing a broader consolidation strategy, or preparing for investment or sale.
6. BDO USA
BDO has substantial operations in both Dallas and Houston, two markets that capture very different parts of the Texas economy.
Its Dallas practice works with companies in manufacturing and distribution, natural resources, technology, healthcare, private equity, and other industries. The Houston office provides assurance, tax, and business advisory services while bringing particular industry depth in natural resources and energy, manufacturing and distribution, private equity, and technology.
That industry coverage is useful for mid-market businesses because growth challenges are often sector-specific.
A software company’s revenue recognition, multistate sales tax, and equity compensation requirements look different from the issues facing an energy business or manufacturer. Private equity-backed companies introduce another set of expectations around reporting, transaction readiness, integration, and eventual exit.
BDO’s multidisciplinary structure allows businesses to access specialists as these requirements emerge.
7. CLA
CLA, or CliftonLarsonAllen, has built its practice around privately held businesses, owners, and organizations that often require more than a conventional annual accounting engagement.
The firm has a presence in Texas, including the Dallas area, and combines audit, tax, advisory, wealth advisory, and outsourcing capabilities. Its model is particularly relevant to mid-market businesses that need to expand the capacity of their finance function as they grow.
That need can appear well before a company is ready to build every financial specialty internally.
A growing business may have a capable controller but lack a CFO-level resource for a specific strategic project. Another may need stronger financial reporting, cash-flow planning, or accounting processes before pursuing financing or an acquisition. Others need additional tax expertise as operations expand across state lines.
8. Grant Thornton
Grant Thornton has an established presence in the Texas accounting market, including Dallas and Houston, and offers a broad combination of audit, tax, and advisory services.
For growing mid-market companies, its relevance becomes particularly clear when accounting decisions begin intersecting with broader business transformation.
An organization preparing for a transaction may need financial and tax diligence. A company modernizing operations may need technology or risk advisory alongside financial reporting. Expansion can create additional tax jurisdictions, new regulatory responsibilities, and pressure on internal controls. Private equity investment can accelerate many of those changes simultaneously.
Grant Thornton’s service portfolio allows companies to draw on specialists across these areas without treating them as unrelated projects.
The firm can also be relevant to companies moving toward more demanding financial reporting environments. Growth may introduce lender requirements, outside investors, acquisition accounting, or preparation for capital-market activity, each of which raises expectations around the quality and consistency of financial information.
9. Baker Tilly
Baker Tilly provides another national accounting and advisory option with an established Texas presence. Its North Texas operations include Frisco, and the firm’s expanded organization provides access to audit, tax, consulting, transaction, and industry-focused capabilities. Recent North Texas market data places Baker Tilly among the larger accounting practices operating in the region.
For mid-market businesses, the firm’s broad advisory model can become useful when growth requires both accounting support and operational change.
Consider a manufacturer expanding production capacity. The immediate accounting questions may involve tax and financial reporting, but the broader project can touch incentives, supply chain, technology, workforce, and capital planning. A company pursuing acquisitions may similarly need diligence, tax structuring, integration assistance, and stronger post-close reporting.
For organizations reaching that stage, access to specialists outside the company’s original Texas market becomes increasingly useful.
Why Mid-Market Growth Changes the CPA Relationship
The right accounting relationship for a $20 million business may look very different when that company reaches $100 million.
This is not simply because there are more transactions to record. Growth changes the types of financial decisions management has to make.
A company operating from one Texas location may initially have relatively concentrated tax and accounting obligations. Add employees in several states, remote sales, new legal entities, acquisitions, investors, and international customers, and the finance function begins managing an interconnected set of requirements.
Four transitions tend to matter particularly quickly.
-
Compliance becomes multijurisdictional. State and local tax obligations can expand as a company hires, sells, acquires, or establishes facilities outside its original market.
-
Financial reporting becomes more important to outsiders. Banks, investors, private equity sponsors, boards, and potential acquirers may require more formal and timely financial information.
-
Transactions become part of growth strategy. Companies that previously grew organically may begin evaluating acquisitions, recapitalizations, or outside investment.
-
Internal processes need to scale. Accounting workflows designed for a smaller organization can become inefficient or unreliable as transaction volume and organizational complexity increase.
This is why mid-market companies often need more than a larger version of the same accounting service they used as a small business. They need access to different specialties at different points in the growth cycle.
Five Questions to Ask a Texas CPA Firm Before the Next Growth Stage
A firm may offer audit, tax, and advisory services on paper without necessarily having the right depth for a particular business. The evaluation process should therefore focus on how those capabilities would work in practice.
-
Who will actually work with our company? Understand the expected involvement of partners, specialists, and day-to-day team members.
-
Which clients have growth patterns similar to ours? Industry is important, but so are ownership model, transaction activity, geographic footprint, and organizational complexity.
-
What happens when we acquire a company? Even if no transaction is imminent, the answer reveals how well tax, diligence, accounting, valuation, and post-close capabilities work together.
-
Can the firm support expansion outside Texas? Multistate and international resources become increasingly relevant as geographic reach expands.
-
Which services can be added without rebuilding the relationship? A company that begins with tax may later need an audit, Quality of Earnings, SALT analysis, valuation, technology advisory, or outsourced finance support.
The answers provide a better picture than a service list alone. A growing mid-market company needs a CPA firm that can understand the business at its present stage while having enough depth to remain relevant when the next stage introduces a completely different set of questions.
Frequently Asked Questions
What should a mid-market company look for in a Texas CPA firm?
A growing mid-market company should consider audit and tax capabilities alongside transaction experience, SALT expertise, industry knowledge, advisory resources, and geographic reach. The appropriate mix depends on how the company expects to grow. Businesses pursuing acquisitions, entering additional states, accepting outside investment, or expanding internationally may require specialist capabilities well beyond recurring tax compliance and financial statement preparation.
When should a growing company consider changing CPA firms?
A change may become worth evaluating when the existing firm no longer has the technical resources required by the business. Common triggers include acquisitions, new audit requirements, private equity investment, multistate expansion, international operations, increasingly complex tax issues, or a need for specialized advisory support. The question is less about company size alone and more about whether accounting requirements have outgrown the existing relationship.
Why is SALT expertise important for Texas companies?
Texas-based companies can develop tax obligations outside Texas as they add employees, customers, inventory, facilities, or acquired businesses in other states. Economic nexus rules can also create obligations without a traditional physical location. SALT specialists can help evaluate nexus, sales and use tax, income and franchise tax, property tax, incentives, registrations, historical exposure, and the multistate implications of business expansion.
Do mid-market companies need transaction advisory services?
Not every company needs transaction advisory continuously, but the expertise becomes important when acquiring or selling a business, raising investment, or preparing for an exit. Services can include Quality of Earnings, financial and tax due diligence, working capital analysis, transaction structuring, purchase accounting, and post-close support. Companies pursuing acquisition-led growth may use transaction advisors repeatedly as part of their broader growth strategy.
