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
