Small business funds are a primary source of financing for entrepreneurs and small business owners. These funds can be used to develop a new business, bring a business idea to life, or grow an existing company. Businesses need small business funds for a variety of reasons. For instance, some require fresh funds to finance their long-term growth; others only need to cover an unexpected cost (like small infrastructure repairs or a larger-than-normal utility bill), while others need funds to cover cash flow gaps or even to take up an unexpected opportunity.
