About Us

"Our vision is to empower growing businesses with the financial knowledge that turns accounting into a powerful tool to build a successful business.”              

 - Leah Thiss, CEO and President, BBBS Inc.




BBBS Inc. was founded in 1992 when the principals recognized that small and medium-sized businesses needed cost-effective accounting solutions in order to grow and prosper. Since then, our company has delivered on its mission to provide innovative, practical and top-quality accounting services that save time and improve the way people do business accounting.             

Building a long-term relationship with our clients is a key to our success. We have achieved this by adhering to our core values. At BBBS Inc. we are:


  • Committed to making world class business accounting affordable to growing businesses.
  • Committed to protecting the confidentiality and integrity of our clients’ business information.
  • Committed to building professional relationships based on mutual respect.
  • Committed to being a productive member of our community.

Most of our clients are referrals from business analysts and consultants, investment bankers, CPAs, venture capitalists, and banks, as well as, from existing clients. All of our referral sources recognize the value BBBS Inc. can bring to an organization.


BBBS Inc. has offices in California and Arizona from which we service clients located across the United States. Some clients have parent companies we report to overseas. Using today’s technology, we can securely connect to our client and operate as if we are just "next door," regardless of the client’s actual location.


We offer five categories of services: Full Accounting Department; Controller Services, CFO Services, Special Accounting Services, and Bookkeeping Services. Based on your specific requirements, BBBS Inc. will build an accounting system and service package that will cost-effectively deliver the information you need to proactively run your business.
