About DMO Accounting

At DMO Accounting, we specialize in helping contractors, startups, and family-owned trades simplify their finances and grow with confidence. From HVAC and plumbing to electricians, landscapers, remodelers, and builders, we provide accounting and tax solutions designed for the trades.

I am Derek Orendorff, CPA and founder of DMO Accounting. With over a decade of experience, I bring accuracy, clarity, and responsiveness to small business accounting. My focus is helping trades owners gain financial control through job costing, payroll, cash flow planning, tax strategy, and succession planning.

What makes DMO different is our client-first approach. Contractors cannot wait weeks for answers, especially when payroll or job costing questions arise. I respond quickly, deliver on time, and provide proactive advice that helps my clients stay ahead of problems rather than reacting to them.

I believe that trades businesses are the backbone of our communities and the heart of America. Contractors keep our homes comfortable, our lights on, our water running, and our buildings safe. They work long hours, take risks, and provide good jobs that support families. Many of these companies are small, family-owned operations built on grit, trust, and reputation. Some are passed down from one generation to the next, while others are just starting their journey with the hope of building something lasting.

My mission is to stand beside these businesses as a trusted partner. I want to give trades owners the financial clarity and confidence they deserve, so they can focus on running their crews, serving their customers, and building stronger communities for all of us.

At DMO Accounting, you get the efficiency of modern cloud-based tools combined with the trust that comes from personal service and a handshake when it matters most.
