An e-tender is an event in which the buyer invites multiple providers to supply various information items, in addition to price, within a set period of time. For example, service capacities, transit times, prices or a complete proposal with creative solutions may be requested. In an e-tendering process, bidders never see which prices are being offered. E-tenders have a longer duration and are more solution-driven than price-driven. Terms such as RFx (Request for Price/Proposal/Information), RFQ (Request for Quote) and RFS (Request for Solution) are frequently used in this context.
