What is the disadvantage of franchising for the one-unit franchisee?

When comparing "single unit franchisees" (i.e., a franchisee operating only one franchise location) to "multi-unit franchisees" (i.e., a franchisee operating more than one franchised location) one "disadvantage" of being a "single unit franchisee" (as compared to a multi-unit franchisee) is the fact that there will be a reduced opportunity for achieving additional profits resulting from the "economies of scale" typically experienced by successful multi-unit franchisees. That is, for the experienced and competent multi-unit franchisee there are certain cost savings and efficiencies generated through the efficient management of multiple locations. In terms of negotiating the terms of the franchise agreement (and your rights as a franchisee) as a "multi-unit" franchisee you may possess more bargaining power as compared to a franchisee purchasing a single unit. An additional benefit of multi-unit Franchising may also relate to the additional protections that you may be afforded in the "protected territory" that may be negotiated and included in your franchise agreement. For example, multi-unit franchisees may possess the advantage of controlling a defined geographic territory and, thereby, minimize competing franchisees from within the same franchise system.
