Your CPA, Without the Wait
I’m Derek Orendorff, CPA and founder of DMO Accounting in East Peoria, IL. I partner with small businesses to deliver secure, cloud based accounting that is accurate, timely, and easy to understand. While my systems let me work with clients anywhere, I maintain strong connections in Central Illinois, the Quad Cities where I grew up, and the Dallas Fort Worth (DFW) area where I regularly spend time with family. This approach gives you the efficiency of modern technology along with the trust that comes from real, face to face relationships and a handshake when it matters most.
Here is how I combine modern tools with personal service to give you the best of both worlds:
Cloud-based CPA firm for speed, accuracy, and convenience
Modern receivables and payables to get paid faster and simplify bill payments
Cash flow analysis to keep your business healthy
Bookkeeping, monthly reviews, and clean financial reports for small businesses
Startup support - affordable setup and guidance with the goal of building a long-term partnership
Payroll processing and bookkeeper training to maintain accurate, tax ready files
Business tax support for S-Corps, partnerships, and sole proprietors
