Services
The Business Improvement Group, Inc. was incorporated in 2002. Co-founders Jim Bonvissuto and Patti Sours wanted to bring their executive level finance, operations, and turnaround experience at various fortune 500 companies to small and middle market companies at an affordable level.

They were confident that offering their "BIG" company experience to "small" to "middle" market companies would allow these companies to have access to state of the art methods to improve cash flow, revenues and profits.
BIG can ease the burden and increase the chances of success of your start-up by helping with the accounting, operational, strategic planning and tax areas of your new and existing business. The professionals at BIG have many years of experience with small business and also have started their own small business.
BIG has been very supportive to me throughout the process of acquiring a business. I couldn't say enough about how gracious, knowledgeable and encouraging they have been and how I look forward to continuing to work with them. They have been a wonderful teacher and mentor. The knowledge that Jim and Patti have is priceless.
BIG specializes in finding hidden assets, overlooked opportunities and underperforming activities in companies which are growing, changing or in financial distress. Whether the issues are financial, operational or personnel based, we convert problems into opportunities, weaknesses into strengths, and potential debts into valuable assets.
BIG can help to devise practical savings and investment strategies that help you stay on budget, capitalize on your fiscal strengths and address your financial weaknesses. A continuing education requirement keeps CPAs up to date about constantly changing tax laws so they can provide prudent, year-round tax management counsel.

We have used BIG Financial & Advisory Services to complete our tax returns for almost 10 years with great success. Jim and team are extremely knowledgeable in handling complex tax situations involving: rental properties, stock option & grant processing and identity theft tax guidance to name a few. More important, they possess the ability to make the complex simple. Thanks for all the help.

I have successfully run small businesses for over 15 years and have always relied on Business Improvement Group for tax and business accounting advice. I would never know the difference between the advantages of an S-Corp, a C-Corp vs. an LLC without the advice of Business Improvement Group. They set me on the right course, and have continued to be a reliable partner for accounting needs, as well as business strategy advice more broadly.
