About Us
Our Story
Back Office Bookkeeping and Tax was co-founded by Bill O’Neill and his partner to support small businesses across Western New York with dependable, accurate, and efficient back office solutions including bookkeeping, accounting, and payroll services.
Our mission is to deliver the financial clarity and operational support business owners need, allowing them to stay focused on directing, growing, and strengthening their companies. Clear, reliable financial records also make it easier to secure financing and complete tax filings with confidence.
Meet Bill O’Neill
Bill holds a Bachelor of Science in Business and Economics from Arizona State University and an MBA from the prestigious Thunderbird School of Global Management, one of the most respected business schools in the country. He spent over two decades working in finance and accounting operations across some of the most demanding companies in Silicon Valley, from early-stage startups to publicly traded technology firms, building deep expertise in financial reporting, process improvement, and scaling back-office operations in fast-moving environments.
After years on the West Coast, Bill made the decision to come home. Returning to his Western New York roots to be closer to family, he saw a clear opportunity to bring that same level of financial rigor and operational discipline to the small businesses that are the backbone of this region. Back Office Bookkeeping and Tax is the result of that decision. Built right here, for businesses right here.
His hands-on experience spans bookkeeping, payroll, CFO-level financial strategy, and everything in between. He is committed to delivering the kind of accurate, reliable service that lets business owners breathe easier and focus on what they do best.

The Best of Both Worlds
Years of working inside Silicon Valley gave me a front-row seat to how quickly the right technology can change what is possible. My partner and I have taken those insights and built them into the foundation of our practice, because we believe our clients deserve the benefit of that experience.
We use advanced tools that assist us with reconciliation, transaction categorization, and financial review. These tools move through data quickly, flag inconsistencies, and catch the kinds of errors that are easy to overlook in a manual process. The result is more accurate books, faster turnaround times, and fewer billable hours on your invoice. That savings goes straight back to you.
And here is what sets us apart: every set of financials that leaves our office has been personally reviewed by me before it reaches you. The tools do the heavy lifting and I make the final call. You get the speed and accuracy of modern technology combined with the judgment of someone who has spent over two decades doing this work. That is the kind of partnership we are here to offer.
Bill’s Promise to You
Your books will be accurate. Your questions will be answered. And you will always have a real person in your corner who cares about your business as much as you do.
