You should start your selling journey from the perspective that the buyer wants to know everything you know about your business, staring with your reason for selling. Accordingly, the valuation you assign to your business must be well formed and documented. The financial package of information that needs to be provided must be bullet proof, without gaps. It is most likely you will need a business broker and whilst he will derive a significant commission a good broker will be well worth the savings from less distractions, he will sort the tyre kickers, identify targets and negotiate the best possible result for your business sale.
