Requirement
Requirement
A buyer’s structured need: the item or outcome, quantity, location, timing, acceptable alternatives, and constraints. A requirement can begin with unknowns, but those unknowns stay visible.
Canonical product
Canonical product
A supplier-independent identity based on the manufacturer and manufacturer part number. A distributor stock code or listing title can point to the product, but does not replace its identity.
Listing
Listing
A source’s published description of an item. A listing is evidence of a possible route, not proof of current stock, condition, or authority to sell.
Offer observation
Offer observation
A dated record of price or availability reported by a source in a stated market. It is useful for research and comparison, but it is not a current quotation or reservation.
Quotation
Quotation
A supplier’s current commercial terms for a specific recipient and scope. Check validity, quantity, delivery, tax, exclusions, and who is authorised to rely on it.
Approval
Approval
A responsible person’s decision on an exact next step. Research, rankings, drafts, and API responses do not count as approval.
