A pre-qualification list is a term used to define a series of suppliers who are confirmed as being able to deliver particular goods or services of a quality that meet outcome expectations. A pre-qualification list can be populated from pre-existing transactions and work arrangements with suppliers, or acquired from new suppliers through the use of pre-qualifying documents such as a request for qualification. On Tradogram, suppliers can be categorized, assigned with different types, and have evaluation scores associated with their profiles. Flexible request documents can also be issued to suppliers of interest to gather additional information.
