If you have a proven track record -- usually 3 years of financial statements and a profitable future -- you have more options and opportunities to get money from lenders and investors. Banks are more likely to offer you loans and investors are more interested in putting their money into companies with solid financial and business histories.
You have the option of borrowing money from a small business loan organisation or a bank. Banks basically offer three loan products: overdrafts, term loans and mortgages. You need to know the difference between them and how to protect your own assets when taking a loan.
If you just need a small loan you could consider microfinancing.
