Small businesses support local economies by creating jobs and providing products and services, yet 50% of them fail within 5 years and only 30% of them survive for 10 years or more. The purpose of this qualitative explanatory case study was to explore how bookkeeping strategies helped 1 small business owner to sustain business growth over time. The sample was comprised of 1 small business owner who has been in business at least 5 years, experienced success, and achieved sustainability in Wake County, North Carolina. Systems theory served as the conceptual framework for this study. The data were collected through a semistructured interview and review of company documents. Transcript review and member checking were completed to strengthen credibility and trustworthiness. Based on methodological triangulation of the data sources collected, 3 themes emerged: the accountant as an advisor, the accounting system and processes, and the relationship between owner and accountant and between accountant and employees. The findings from this study may contribute to social change by providing insights and strategies for small business owners, accountants, and academics to rethink how to approach business. Accountants with advisory and management accounting skills could benefit small business owners. Future accounting students could prepare to help small business owners by gaining advisory and management accounting skills. The data from this study may contribute to the success of small business owners' growth, sustainability, and prosperity and, subsequently, benefit their local economies.
