Who We Are

We are a very unique team of individuals who are well established in the Canadian bookkeeping industry and have a passion for educating those who wish to be better bookkeepers as well as small business owners who wish to understand more about their own books. We advocate for qualified, certified bookkeepers and believe that small businesses deserve skilled professional bookkeepers who can assist them in learning more about their company’s financial health.
We created Trifold Bookkeeper Advisors to promote progress in the profession. Here are the major players in that endeavor:
