A supplier master is the controlled set of core data that identifies and describes suppliers used by an organization. In manufacturing, it commonly supports purchasing, receiving, supplier quality, traceability, and ERP or MES integration.
A supplier master record may include supplier names, addresses, contacts, payment terms, supplier codes, approved status, commodity or process scope, quality classifications, certifications, and links to customer or program requirements. The exact fields depend on the business system and the controls applied to supplier data.
The supplier master is not the same as a purchase order, contract, approved supplier list, or supplier performance report. Those records may reference supplier master data, but they serve different purposes. In regulated or quality-sensitive operations, changes to supplier master data can affect downstream workflows such as purchasing authorization, receiving inspection, source traceability, and first article inspection review.
