Dear Buyer, prepare the listing of items that you wish to purchase through reverse auction, the unitary max prices and the purchasing volume on specific period (monthly/annual).
Calculate auction Base Value
Having the weighing
Suppliers who participate on reverse auctions for lots, will bid only ONE VALUE. This amount corresponds to the sale value of the lot in the considered period (one month in this example).
Auction Base Value
Weighing % of Total
With the subsequent offers presented by invited suppliers (each one the lowest), You will be able to determine the new unitary prices, based on weighing %s of each item.
Auction with several items
- Easy to carry out if a clear (and single) Base Value for the auction is determined .
- To obtain a better economy of scale, buyer should consider an important period of time (one year or one month of purchases).
- Buyer needs to establish the way unitary prices will be calculated once auction finishes (this example - weighing %), and comunicate the chosen procedure to invited suppliers.
- Auction lowest value (winner) could be composed with different unitary prices, therefore buyer (auction owner), needs to define clear rules about expected unitary prices variations.
