In addition, the auctions are also displayed on the home page (HOME) in the dashboard (see 2.1) as colored tiles “New auctions” or can be viewed via the COCKPIT (see 2.2) by clicking on the number of queries displayed. 

The order auction (Reverse Auction) is a form of negotiation in which the buyer requests a service and suppliers undercut each other in price for providing this service. The reverse auction on Newtron can be carried out as a price, ranking or traffic light auction. In individual cases, the auction types can be combined. 

The client is partially not not obligated to choose the supplier with the lowest price. He is free to decide which supplier to award the contract to (good evaluation, proximity, etc., are also very important). No automatic contract allocation takes place. The award procedure communicated by the purchaser applies. 

1. Receipt of invitation mail after opening of auction by buyer

2. Log in to Newtron to see auction details

3. Confirm or cancel your participation on Newtron

4. Independent training in a test auction or together with Customer Services

5. Creation of a bid template for extensive price items

6. Timely bidding of the 1st bid -> contact Newtron immediately in case of problems (see 9).

7. Submit desired follow-up bids, taking into account the remaining time

8. At the end of the auction, the buyer independently evaluates the auction.

-> Please contact the purchaser directly with regard to the award of the contract! 

a)Price auction 

The price auction is very transparent for suppliers because the bidders see the competitor prices directly. However, the market situation is usually only visible after the first own bid has been placed. One or more items can be assigned completely (m2s auction) or different packages can be negotiated (m2m auction). In the case of a package auction, a bid must be submitted for each package individually. You can, but do not have to bid on all packages. Partial bids within a package are not possible. 

b)Ranking auction 

In a ranking auction, the supplier receives a direct ranking display, e.g. rank 3, after submitting his first bid. This means that two bidders have placed cheaper bids. The difference to the best bid is not displayed to the vendor. One or more items can be assigned completely (m2s auction) or different packages can be negotiated (m2m auction). In the case of a package auction, a bid must be submitted for each package individually. You can, but do not have to bid on all packages. Partial bids within a package are not possible. 

c)Traffic light auction 

The traffic light auction is a special form of ranking auction in which the supplier’s ranking is not displayed directly but as the color status of green, yellow or red. The auction is also called target price auction because the purchaser enters a target price , the achievement or non-achievement of which is displayed to the supplier. One or more items can be assigned completely (m2s auction) or different packages can be negotiated (m2m auction). In the case of a package auction, a bid must be submitted for each package individually. You can, but do not have to bid on all packages. Partial bids within a package are not possible. 

The bidder receives feedback on his bid with the color status: 

RED: The bid is far from the target price; bad bid compared to the competition 
YELLOW: The bid is in midfield. 
GREEN:  The supplier is the best bidder AND has reached the target price. 

In most cases, target price information is displayed. As soon as you have reached the target price, the display changes from “Target price deposited” to “Target price reached”. 

You are in the Request overview (see 6.1 “Where can I find the auctions to which my company is invited?”). Click on the ID number to get to a detailed view of the individual requests, e.g. “lsa126028”. 

The color icon to the left of the request number shows you the current negotiation status: 

Yellow bordered = not started 
Partly yellow = will start shortly 
Red = expired 
Green = currently running (test auctions usually run for several days until the start of the live auction) 

In Auction view you will find different tabs in the Auction Data area below Header Information, Opener and Runtime: 
The “Mode” tab displays information about the auction type and renewal modalities. 
In the “Item data” tab you have an overview of all items for which a price must be submitted. Partial bids are not possible in an auction.  
In the case of a package auction, the tab is called “Packages”. It gives you an overview of all packages and all items per package. You can, but do not have to bid on all packages. Partial bids within a package are not possible. 
To view further details such as conditions, delivery and contract data, please click on the respective tab. There is often little data stored here because it should be known from the call for tenders. 

The different areas, such as auction data or activities, can be minimized or maximized by clicking on the arrow symbol on the right side of the line.  
If the auction is already running, the auction data area is minimized and the activities area below it is maximized, since bidding takes place here (see point 6.9 Bidding).  
In the case of a package auction, you will find a package overview here, where you can see the runtime of the individual packages or click on the package names or the hammer symbol to access the respective packages.  

Please inform the buyer via Newtron in good time before the auction starts whether you would like to participate in the auction or not. To do so, in the auction view (see 6.4) , under PARTICIPATE, select the item “Accept participation”. 

If you cannot or do not want to participate in the auction, please select”Cancel participation” in the auction view at the bottom right. On the following page, select a reason for rejection and then click on “Send rejection”. 

In most cases there is a test auction parallel to the real auction.  

This test auction is for practice only and has the same auction mode and structure as the live auction. The item data, quantities & prices are fictitious. All test bids are absolutely non-binding. 

The test auction is indicated as such in the overview by a corresponding symbol in front of the title and in the auction details by the text reference “Test auction”. In addition, you will find corresponding information on the Conditions tab and in the item data. 

You can place an unlimited number of test bids until you feel familiar with the auction process. The Customer Services Team will be happy to assist you (see 9 contact data Newtron). 

The creation of a bid template before the auction starts is optional and recommended when numerous items are being negotiated. It means that you can set your prices in the system before the auction starts, so that you can then quickly send the 1st bid at the start of the auction. 

You are in the auction view (see 6.4 auction details). Now select “Create bid template” and click on “Run”. Open the item view by clicking on the folder symbol on the left. After you have entered your price, click on “Save partial bid”. To save the bid template, click on “Create bid template”. 

Important: When the live auction starts, you must submit your bid online! The text indicates the start of the auction. 

Note: If the auction was created on Newtron from a previous bid invitation, the action “Transfer last bid from pre-negotiation” is displayed. Click on “Execute” before you enter the prices again. 

You are in the auction view (see 6.4 auction details).

To upload your Excel bid, locate your saved file using the “Browse” button and then click “Upload”. 

After checking your bid, click on “Submit bid”. You will receive a confirmation and then click on “Continue to the auction view”. 

With a price auction without packages, you will see your best bid and the best bid of the competition (if available), including the difference between your bid and the best bid directly in the bid monitor. In a price auction with packages, you can see the current best bid per package in the “Current packages” view. In a price auction, in addition to the bid monitor, you can follow the course of the auction in a graphic. To do this, click on “Chart” at the bottom left. Green points in the chart are separate bids. All competitor bids are displayed anonymously in purple. 

In a ranking auction without packages you can see your ranking directly in the bid monitor. In a ranking auction with packages, you can see your ranking per package in the “Current packages” view. If you are rank 1, it is displayed in green. 

With a traffic light auction without packages you can see your color status directly in the bid monitor. In a traffic light auction with packages you can see your color status per package in the “Current packages” view – for further information, e.g. regarding reaching the target price, click on the package name. 

The information from the bid monitor is also displayed in a monitor on the right-hand side of the screen. 

Various notices, warnings or error messages may appear during the bidding process. Here is an overview of the most important messages: 

Maximum price 

The auction often sets a maximum price. This means that higher prices can not be given.  
If your bid is more than 10% below the maximum price, you will receive a message which you must answer with “YES” (I really want to give such a low price) or “NO” (I mistyped). 

Minimum bid difference 

If you want to submit further bids after bidding, you must pay attention to the minimum bid difference. The total price of your new bid must be less than your last bid minus the minimum bid difference. 
In the case of a price auction with a standard setting, you must underbid the best price of the competition minus the minimum bid difference from the second bid in order to be able to submit the bid. 

Possible lifetime extension of the auction 

Depending on the mode set and the associated options, the entire auction or certain packages can be extended when new bids are received. This gives you the opportunity to send another bid if, for example, you have been underbid shortly before the end of the auction.  

The settings for extension defined in the respective auction can be viewed in the “Mode” tab under Auction renewal . 

Automatic screen refresh 

Once you have reached your desired color status, ranking or best bid, you can continue to monitor the course of the auction. Please note that the check mark in the lower right corner is set in front of “Update”, so that the auction view is automatically updated every 30 seconds. 

In the auction view (see 6.4) please switch from the bid monitor to the tab “Sent bids”. Here you can see your own bids and all anonymous competing bids in a price auction.  

For an auction with packages, first go to the “Package overview” and click on the respective package name. In the package view, please switch from the bid monitor to the “Bids” tab. 

To view the details of a specific bid, click directly on the bid number (e.g. “b135439”). At the bottom left you will see the button “Print offer”. If you want to print out all items including specification texts, you can activate the print settings at the top of the print view by ticking the box “Show many details”. Now click on “Update print preview”. You can then print out the offer by clicking on the corresponding button. 

Once the auction has expired, you can call up the auction in two ways:
