Is a major reason why business fail financially?

A major reason businesses fail financially is poor cash flow management, which can stem from overestimating revenues, underestimating expenses, or not effectively managing accounts receivable and payable. Additionally, a lack of market research and understanding of customer needs can lead to ineffective product offerings and decreased sales. Inadequate financial planning and budgeting further exacerbate these issues, ultimately jeopardizing the business's sustainability.
