South Denver's bookkeeper for real estate investors and growing businesses.
Clean books are just the beginning. Kellcat builds the complete financial system — monthly bookkeeping, custom dashboards, bi-weekly advisory, and accounting architecture for tech-enabled startups. Where Accounting Meets Engineering.
Not just a bookkeeper. A financial systems partner.
Most bookkeepers reconcile your accounts and send you a report. Kellcat builds the entire financial back office — from the monthly close to a live dashboard that answers your questions in seconds, to bi-weekly advisory sessions where Brian reviews your numbers with you and helps you make confident decisions. For tech-enabled startups, Kellcat also designs the accounting architecture your engineering team builds to before the first transaction posts.

What South Denver clients are saying.
“My books were a complete disaster. Brian from Kellcat helped me clean them up and also showed me which metrics I should be tracking. His knowledge of QuickBooks blew my mind. He showed me stuff I didn't even know was possible. I would highly recommend working with him.”
“Brian has been very great to work with and help refine our QuickBooks Online. I'm working on flipping houses, and Brian has reviewed our settlement statements to track everything properly as well as provide some insight into how others track costs to optimize reporting and visibility.”
“I had a fantastic experience with Brian from Kellcat. His knowledge in the field was truly impressive. I left feeling confident and well taken care of, knowing that my financial records are in good hands. He is absolutely a pleasure to work with.”
