Selling a business often involves hiring a business broker to manage the process. Brokers typically charge a commission based on the final sale price. This fee, ranging from 8% to 12%, compensates for their expertise in valuing the business, finding qualified buyers, and negotiating deals. Some brokers may also request an upfront fee or a monthly retainer to cover initial costs or marketing efforts. The commission is usually negotiable and can vary depending on the size and complexity of the business.
