Invite: Bidder Configuration

This screen allows you to configure the lots viewable per bidder, and also apply adjustments per bidder and lot. For example, unchecking the box for ‘Visibility’ next to a lot means that the selected bidder won’t be able to see that lot.

There are two ways to configure the data:

  • Online - use the 'Choose a bidder:' selection at the top left to select a bidder, and then modify the lot visibility and adjustments (explained below).
  • Offline - download an Excel version of this screen by clicking 'Download'. Make your changes in Excel, save the file, and then upload it using the 'Upload' button.

Changing Lot Visibility

Changing the lot visibility means that you want to show or hide a lot from a bidder. By default, all lots are visible to all bidders. To change the visibility:

  • Online - Check the 'Visibility' box for the applicable lot(s). An unchecked box means that the lot won't be visible.
  • Offline - Use the word 'FALSE' in the 'Visibility' column to hide a lot ('TRUE' means that the lot is visible).

Apply Bonus/Malus (Adjustments)

You can also use the ‘% Bonus/Malus’ and ‘Turnover Bonus/Malus’ columns, both online and in Excel, to favor or penalize bids from certain bidders for specified lots:

  • % Bonus/Malus: This is expressed as a fraction, such as 0.50 (50%). A positive value favors the bid by reducing it by that percent. A negative value, such as -0.50 (-50%), penalizes the bid by increasing it by that percent.
  • Turnover Bonus/Malus: This is expressed as a currency value, such as 100.00. A positive value favors the bid by reducing it by that number. A negative value, such as -100.00, penalizes the bid by increasing it by that value.

On the bidder-side screens, the adjustments impact the feedback, which will be based on the adjusted bid. For example, if two bidders enter a bid of $100,000 but Bidder 2 has a malus of 20% (-.20) then, because of the adjusted bid of $120,000 (see Figures 1 and 2 below, both showing feedback for the same bid value - except that the bidder in Figure 2 has the malus applied):

  • Bidder 2 won’t see the winning icon (the default ‘Low Cost Baseline’ scenario will award to the other bidder instead).
  • Bidder 2 will see a lot rank of 2 instead of a rank of 1.
  • Bidder 2 will not meet a reserve price/feedback target of $100,000 with a bid of $100,000 (the reserve will be compared to the adjusted bid).
  • The difference to next rank/first rank will appear as $16,666.67 (16.67%) since a bid of $83,333.33 is needed to equal the other bidder’s bid of $100,000 ($83,333.33 * 1.20 = $100,000).
  • The minimum bid decrement and maximum next bid feedback will be affected if the target value is based on the next ranked lot bid or first ranked lot bid.

As mentioned above, scenario allocations will also be impacted by any bidder adjustments for lots.
