Background and History

Business Books South West was started in 2012 when the business owner, Mark Jennings, saw a need for a business that could help out other small businesses with the parts of their businesses that owners often struggled with - accounting and bookkeeping. As a qualified Accountant, Mark had seen a number of Mum and Dad business owners who put great energy into the parts of the business they loved, such as being a tradesman, but had little experience with the paperwork side of the business, let alone the enthusiasm to try and tackle the task themselves.

Since then, Business Books South West has been able to assist various businesses and not-for-profit organisations with various aspects of their work, from the day-to-day bookkeeping to setting up efficient systems and structures, evaluation of business systems and assistance with business advice.
