Here the common answer I find: Feasibility study
A formal document presenting an overview of your business can help you recruit potential partners, investors or lenders. It should detail the following aspects of your business:
-- The product or service: What are its unique features?
-- The management team: Does your team have experience in the industry?
-- The market: Who are the target customers? How big is the potential market? What are the costs required to reach the target market?
-- The competition: Who are your major competitors? Is your product or service superior to the competition?
-- The costs: What will it cost to start and run your business?
Don't rely on credit cards
Credit cards are a tempting but expensive source of capital for starting a business. If you resort to them for cash, your business plan should include a schedule for paying back that money within a year or so.
