For entrepreneurs, an SPA is essential for several reasons: 1. Legal Protection: It provides legal protection to both the buyer and the seller by clearly defining the terms of the sale. 2. Clarity: It ensures that all parties have a clear understanding of their rights and obligations. 3. Risk Management: It helps in identifying and managing potential risks associated with the sale of shares. 4. Investor Confidence: It builds confidence among investors by demonstrating that the business is well-organized and legally compliant.
