Now here's a data point for franchisors: Whatever you think it'll cost you to start franchising your business, you may want to double that. Many factors can impact the amount of startup capital you'll need, including the industry you're entering, the amount of experience you have, the speed at which you want to grow, and endless outside factors from real estate (if you're entering a brick-and-mortar business) to the cost of labor (if you need employees). And if you plan to work with an FSO, broker, or other third-party seller, make sure you have even more cash on hand. You'll need it.
