Requirement-led, not catalog-led
The starting point is the buyer's actual need—not whatever happens to be listed in a storefront.
Options stay comparable
Domestic inventory, made-to-order, factory-direct, exact-match, equivalent, faster, and lowest-landed-cost routes can be shown as distinct options with their own assumptions.
Confidential information stays separated
Buyers do not see internal cost or margin. Suppliers see only assigned bid information. Organization and role boundaries are enforced on the server.
Approval history survives revisions
Clarifications, documents, quote versions, samples, and acceptance events remain tied to the right record.
