In the English auction (Standard auction), Suppliers reduce their prices based on the specified parameters (in the upper right corner of the screen).
The lower part of the screen displays procurement items (within procurement groups) for which the client is requesting an offer, defined initial unit price, quantity, and other elements.
A notification of the auction start displays in the Supplier Portal after the buyer starts the auction. The auction overview contains general information, procurement items and parameters.
The competitor can submit his offer or bid by entering the desired amount in the "Bid" section, afterwards the "total amount of the offer" is calculated automatically based on the unit price submitted by the competitor.
Clicking the Bid button submits the entered bid.
