Why Franchise? Franchising (from the French for free) is a method of doing business wherein a franchisor licenses trademarks tried and proven methods of doing business to a franchisee in exchange for a recurring payment, and usually a percentage piece of gross sales or gross profits as well as the annual fees. (from Franchise PH) This is like starting a business by copying a successful business concept. That how business works, this is the reason Jollibee has many branchs and this is why many fast food brand comes popping out, they're copying how Jollibee started but with different brand and product lines.
Franchise brand has a ready market, therefore the franchisee have an instant brand name recognized with created customers. A franchisee also has a back-up support from the franchiser when ever he needs it. Franchiser provide training from facilitating plans, operation, inventory, maintenance and specially the accounting system (proper documentation) This is where most business failed by tracking it's earning from the owners expenses. Ever wonder how market "palengke" vendors keep on making loan to loan sharks like "bumbay" to refurnish their capital.
The best reason it is a minimum risk business (nothing is 100%, even Big fast food franchise fail also) But with a franchise business the future of your business is clearer. Some of the in demand franchises are Bakery (Julies Bakeshop, love the pandesal here) and Parlor (Reyes Hair Cutter). Computer internet cafe are also in demand right now, check out this Google Page i've created. For more list or directory of franchises click here.
