“I have known, and benefited from the knowledge and experience of, Shirley Wood, since 2010. Over the next 13-ish years, while serving in two different non-profit ministries, I was in charge of the finances and bookkeeping, and I greatly appreciated knowing that I could always rely on Shirley to help me with some of the more complicated aspects of the job, and, more specifically, QuickBooks. Not once did she ever say, “I don’t know…you might need to contact QB Support”! Shirley was always there for me when I needed her – whether it be a QuickBooks challenge, questions about certain IRS forms, helping us file tax returns, etc.

She was also incredibly helpful with the extremely complicated 501c3 application process, that I was also in charge of completing, for one of those ministries. The depth of her knowledge, her reliability, and her swift responsiveness were absolutely invaluable to me, as well as the non-profits I worked with. I cannot recommend her services enough – she is simply the BEST at what she does!”

Kim Thomas, Dir. of Operations/CFO Avid Virtual Services

“It is my privilege to recommend to all of our ministry partners the resource of Calculating Business Solutions and its CEO, Dr. Shirley Wood.

We have known Dr. Wood for over 20 years. She has worked within our organization with great results and as owner of her own company has provided and continues to provide a wealth of services.

I have referred many of our LGN ministries and Non-profits to CBS.

Dr. Wood and her team have the knowledge and skill to assist and aid you in solving those accounting and IRS issues that come your way.”
