Workers are the best source for identifying the business services that your target organization utilizes. Some information on suppliers may be available on Form 990. Section B of Part VII of the 990 lists the five highest compensated independent contractors. In some instances this may include a major supplier of goods or services. Candid, the National Center for Charitable Statistics (NCCS), and the Economic Research Institute all provide access to Form 990 as well as summary information on nonprofit organizations. Also check the New York Charities Bureau.
