A small business loan is a source of funding business owners can access to cover the costs associated with operation and growth. Like personal loans, business owners can get small business loans through traditional banks and credit unions as well as online lenders—including those backed by the U.S. Small Business Administration (SBA). Depending on the type of loan, you can use funds for everything from working capital and equipment acquisition to larger purchases like real estate. Small business loans help companies make large purchases and cover the cost of doing business. Loans generally are issued as a lump sum that can be used to make a specific purchase or manage cash flow and then repaid with interest. However, there are other types of small business loans—like lines of credit, merchant cash advances and invoice financing—that can be used to access cash more quickly and on an as-needed basis.
