“Prequalification” module is designed for those who need to find qualified potential suppliers prior to announcement of a tender. After the prequalification a procuring entity can conduct “Restricted Procedure”, in which only prequalified potential suppliers will be able to submit their proposals. “Restricted Procedure” can be conducted in a form of “One Envelope”, “Two Envelopes” and/or “Reverse Auction”. 

Proposals can be submitted while a prequalification has a status - “submission of proposals commenced”. Suppliers can change or cancel their proposals at any time until the prequalification is finished.
