Trenary & Company LLP is a mid-sized accounting practice in Oklahoma City serving closely held businesses, partnerships, and individual owners who need tax planning integrated with ongoing accounting management, not just annual filing. The firm works primarily with entities structured as S-corporations, LLCs, and partnerships across construction, real estate, healthcare, and professional services industries.
The firm offers tax preparation for business entities and individuals, bookkeeping and general ledger management, payroll processing, and year-end accounting advisory. Because pricing depends on business structure, revenue, complexity, and whether clients bring pre-organized records or require significant cleanup work, hourly rates and engagement fees vary substantially.
For a typical S-corporation with clean records brought in mid-year, expect engagement costs in the $2,000 to $5,000 range for annual tax preparation and related returns. LLCs and partnerships with multiple members or pass-through tax implications run higher. Bookkeeping and compilation services are quoted based on transaction volume and frequency; many clients use these services on a monthly or quarterly basis to prepare for the firm's year-end tax work. Request a specific estimate based on your business structure and current record-keeping state.
The firm is staffed by CPAs (Certified Public Accountants) licensed in Oklahoma. CPAs must maintain continuing education and are held to a professional code of conduct, which provides a higher standard of accountability than non-credentialed bookkeepers or preparers. Trenary & Company structures engagements as ongoing advisory relationships rather than transactional once-a-year filings. This approach allows the firm to assess quarterly tax liability, recommend timing of income recognition or deductions, and advise on entity-level decisions like equipment depreciation strategy or retirement plan setup before the tax year ends. Clients with volatile or seasonal revenue benefit most from this proactive stance.
The Oklahoma City market includes large regional firms (Moss Adams, Grant Thornton) that focus on larger corporations and organizations; small solo-CPA practices that operate part-time or handle primarily individual returns; and mid-market firms like Trenary & Company that occupy the middle ground. Choose Trenary & Company if you operate a closely held business with annual gross revenue between $500,000 and $10 million and need both compliance (tax filing, bookkeeping) and strategy. A larger firm may feel overscaled and charge $10,000 to $20,000 per engagement. A solo practitioner may be less expensive but offer limited availability during tax season and fewer resources for complex entities with multiple owners or state compliance needs. Trenary & Company fills the gap: deep expertise on business entities and active tax planning without enterprise-level overhead costs.
This practice is designed for business owners who want to reduce their own accounting workload and ensure tax liability is managed throughout the year, not discovered in April. It works especially well for firms with owner compensation decisions, equipment purchases, retirement plan contributions, or state apportionment questions. Partners in professional service firms or real estate investors with multiple properties benefit from the firm's focus on pass-through entity taxation.
It does not suit individuals with only W-2 income and a mortgage, who can use tax software or volunteer-run VITA programs for under $200. It is also not the right fit for publicly traded companies or nonprofits, which require specialized audit and compliance skills and are best served by firms with those designated practices.
Initial consultations are typically free or low-cost and allow the firm to understand your business structure, tax history, and current bookkeeping method (or lack thereof). Bring any prior tax returns, bank statements for the current year, a summary of significant transactions or planned purchases, and clarity on who owns what percentage of the business. If you have not worked with a CPA before, be prepared to discuss whether your entity is properly structured for your situation. The firm will then outline a scope of work and provide a fee estimate. Engagements typically begin with a planning meeting in late fall or early winter so the firm can advise on year-end actions.
Confirm current office hours and phone number directly, as accounting firm hours often shift seasonally during tax season (January through April). Most engagements are coordinated via phone, email, and secure document sharing rather than in-person visits, though the firm maintains an Oklahoma City office for clients who prefer face-to-face meetings.
Trenary & Company has built a base of long-term clients in Oklahoma City by combining compliance competence with genuine advisory partnership, making it a logical anchor for an owner-operator deciding whether to invest in year-round accounting support.
