ESAP is an electronic procurement platform that brings purchasing and supply activities together in one system. It provides open access to a catalog of procurement lots and supplier products, as well as buyer announcements. Visitors can review lot terms and details without signing in, while submitting offers and managing company procurement, proposals, and orders requires an account. Companies can register as either buyers or suppliers, with their role selected during registration.

The platform supports the procurement process from identifying a need through delivery and acceptance. Users can form and approve requirements, publish lots, collect and evaluate offers, formalize agreements through contracts and orders, and monitor fulfillment. Electronic trading options include reverse auctions and sealed-envelope bidding. ESAP also features total cost of ownership (TCO) assessment to support offer evaluation. Lot listings can be browsed by status, including open offer periods, completed submissions, and results. By consolidating these stages and tools, ESAP offers organizations a digital workspace for coordinating procurement, supplier proposals, contracting, and delivery.
