Before you list your business for sale, you need to think of what are you trying to accomplish. Are you trying to realize some or all of your capital in your business to fund your retirement? Do you want to retire as soon as possible or do you still want to continue working in the business? Does the business need more financing to grow the business? How will selling your business affect other shareholders, the employees, customers and suppliers?
If you have enough money already, do you want to pass the business to your children and get paid over time? Do you want to sell to your managers? Will you have to assist them in financing by providing a vendor take back loan? Do you take the company public but in the current market conditions, this may not be a viable option at the moment.
