Manage a business. The Lemonade Stand has been a business simulation developed in many different versions. We believe this is the first time that it has been created as a spreadsheet simulation. If you are a young entrepreneur who wants to learn how a business works and how you can use spreadsheets to improve your business we encourage you to try our spreadsheet lemonade stand. It is based on standard business practices and shows you how to build a business model and simulate its profitability.
