Negotiating is an entrepreneur's most important skill," says Jessica Mah, the 20-year-old founder of the start-up InDinero. Before one buys a business, he or she will need to have a proper negotiation strategy in place in order to get the best outcome from the deal. Indeed, the process is different depending on what type of business you plan to buy, if you intend to purchase the rights to the name of an existing business, whether or not you wish to acquire the contents of the business, or if you want to only purchase a businesses' assets.
