About Us

             Anna Tai, Pam Carroll, Pat Carroll, Bill Singh

Pat founded Bookkeeping Plus in July of 1999. Prior to starting Bookkeeping Plus, she worked for 25 years in the auto dealer industry, including spending 15 years as Controller for a large dealership in the Chicago suburbs. Pat relocated to San Francisco in 1995, where she continued to work in accounting for 4 years, before she realized she had a great desire to help small businesses. She saw a need for small businesses to have a partner in all bookkeeping aspects, a role that often isn’t full time in smaller companies, yet is essential in running an efficient company. This vision held true, she often realizes that the biggest hurdle for a new company, and some established ones,  is the need for a financial partner as most “creatives” don’t have the accounting or organizational background that a company needs to grow and thrive.

Pat feels very blessed to be working with a very dynamic team of individuals who share her sense of high integrity, professionalism, united vision, and who work together impeccably.

In her spare time, when she is not being entertained by, or walking her rescued Maltese, Aspen, Pat enjoys spending time with her family, including her 2 daughters and 3 grandchildren. Her ‘hidden’ passion is to be a member of a dynamic, performing Improv Group again. In the quiet moments; her spirituality is an important aspect of her life and spends time each day contemplating her own personal growth and the importance of compassion and understanding for all beings.

In 2018, after serving her clients with high integrity and professionalism, Pat decided to retire. However, she wanted the successor to possess the utmost level of integrity, skillset that meets the client expectations and willingness to take the company to the next level.

Bill Singh spent most of his career in public accounting, consulting with clients on their processes and accounting needs. He helped shape the entire front and back office functions of many of the companies he has worked with, giving him a unique insight into the often complex and multifaceted stages of starting, growing and maintaining a small business.

Bill completed his undergrad work at San Jose State University and soon after he got placed in a regional CPA firm in Dallas, Texas, where he worked for next few years in public accounting and earned his CPA designation before he decided to succumb to his adoration of the San Francisco Bay Area.

Bill is particularly skilled in accounting correction or catchup projects, corporate tax and individual tax planning & preparation and IRS notice resolution.

Bill is an avid tennis player and he enjoys spending his free time with his two daughters and his tan rescued chihuahua, Dodi.

She came to Bookkeeping Plus from Las Vegas where she worked for over 10 years as the Operations/Office Manager for an Electrical Contractor; prior to that she worked over 10 years as the bookkeeper for a very busy Ophthalmology office.
