To obtain start-up funding, first you must map out what you need the finance for. You should detail how this money will help the business develop and grow. You'll need to produce forecasts for sales, cash flow and profits.
This will provide a potential source of finance, such as the bank or an angel investor, with an understanding of how the funds will be used. It will show them what the finance will do for the business. Sources of finance could include investors who will look for a form of equity or, a bank in the form of a bank loan. Check carefully for which option suits you best.
