Owning an audit firm requires planning, hard work, perseverance, and investment. Most accountants start by either starting from scratch, having a part-time practice, finding a partner, or buying an existing practice. Developing a comprehensive business plan is important, outlining goals, services, marketing strategy, costs, and financial projections. Significant financial resources are needed as new businesses experience cash flow issues in the startup phase until established. Initial costs include office space, equipment, software, staffing, and licenses.
