A supplier is an individual or an organization capable of providing certain goods and services to buyers who desire to purchase them. A supplier may provide their goods and services directly through a straightforward transaction, but can also serve as contractors who provide goods and services over a period of time. On Tradogram, a database serves as a directory for storing profile information about each supplier. Multiple points of contact can be established when necessary, financial details and be saved for automatic use in transactions, and external files can be uploaded to each supplier profile.
