Do you want to franchise a restaurant, or do you wanr to buy a franchised restaurant ?
Most established restaurants in South Africa request an upfront fee for their franchise documentation.
This can be anything from ZAR 150,000 to ZAR 1 Miillion. This payment is then offset against the Franchise Fee if you buy a franchise. Otherwise you loose it.
This documentation has full guidelines and criteria.
I was involved some time ago in preparing a Business Plan for an O' Hagans Restaurant.
