Who we serve

Deep expertise across the industries that drive Tulsa's economy.

What to expect when you work with us.

Transparency is part of the plan. Here are answers to the questions we hear most.

Ask a question

We serve both business owners and individuals. Many of our clients are business owners who need personal tax planning alongside their business services. We also work with professionals, real estate investors, and retirees who need specialized tax guidance.

Our pricing is transparent and based on the scope of work, not hidden hourly rates. After an initial consultation, we provide a fixed fee quote so you know exactly what to expect. We offer monthly retainer packages for ongoing services and project-based pricing for one-time needs.

We work with all major accounting platforms including QuickBooks Online, Xero, Sage, and NetSuite. Our team can help you choose the right software for your business and provide training and ongoing support to ensure you get the most out of your system.

Absolutely. With former IRS management on our team, we have insider knowledge of the audit process. We handle IRS correspondence, represent you during audits, and negotiate settlements when needed. Our 100% audit success rate speaks to our expertise in this area.

We can typically schedule an initial consultation within one week. During that meeting, we will learn about your situation and outline a plan. For urgent matters like IRS deadlines or audit responses, we prioritize immediate support.

Let's build a smarter tax strategy.

Tell us what you're working on. We'll respond within one business day.
