Focus on your business.

Stop stressing about your books.







We develop an understanding of your business, existing processes, personnel involved, current pain points, and what you’d like to achieve.


We discuss and ultimately agree on what services you think you need and what we think makes sense for you, how the work will get done, and who will do what. We establish mutual expectations and discuss pricing as well as timing.


We collect logins to existing platforms. The setup and transition is handled by a designated onboarding specialist who works on your first month’s activity (or catch-up work) under the system designed for your business. Questions and answers occur throughout the period.


We deliver our first financial management report to you after the first month’s activity (or catch-up work) is completed, discuss areas for improvement and pain points that we identified during the onboarding process, strategize based on findings and suggestions, and move forward.


Your existing onboarding bookkeeper continues to work with you or a new and dedicated bookkeeper is assigned to your business. They will maintain your financial matters going forward and will be your main point of contact.

“Michelle and Sheryl from Paul’s team are rock stars. They’ve got my reporting being done in a way I can quickly and easily digest. Paul’s a super sharp guy. He understands my business, and he gives great advice. He definitely cares about his clients and wants to build real relationships, and I appreciate that. I’m looking forward to continuing to work together.

“RuthAnn, Paul and the rest of the team continue to dazzle me by always replying almost instantly. They’re proactive, transparent, and smart. Now, I can finally focus on expanding my business even more. Thanks to Paul and his team, I’ve saved a ton of money – and most importantly – time.”

Mathieu Lam

CEO, Yoodac Web Agency Inc.

“My stress level has reduced significantly. Day to day we work with RuthAnn, who is exceptional. She is available 24/7 and it really feels like she’s in the office with us and part of the team. She’s incredibly responsive and really cares about our business. Looking at the bigger picture and our long-term goals, Paul has helped me with corporate restructuring, tax planning, creating a family trust and holding companies, investing, and more. He put everything together so I know my business can continue to thrive and my family will be taken care of. “

“Deuzeman CPA has become much more than our accountants. Paul, Michelle and Lois have become an integral part of our decision-making and planning for the future. Paul’s always thinking about his clients, and will often have a conversation with us, sleep on it, and call in the morning saying “I had an idea and I think you should…”

Accurate Books Guaranteed: At your request, Deuzeman CPA will review your bookkeeper’s work. If your Deuzeman CPA Bookkeeper made an error that requires re-work to your books for any month, Deuzeman CPA will correct the error for the month that error occurred at no additional charge. Eligible errors include those made by a Deuzeman CPA Bookkeeper. An ‘error’ is a transaction that has been incorrectly categorized to the wrong account, an account balance in QuickBooks that doesn’t match the actual account balance or a transaction that can’t be supported by documentation (including client commentary). If you invoke the guarantee, you’ll need to provide Deuzeman CPA with supporting documentation relating to the item(s) in question. Deuzeman CPA Bookkeepers aren’t responsible for errors resulting from incorrect information provided by you or if you record something in the books. Guarantee may be subject to change without notice.
