What is reverse auction?
A reverse auction is a procurement method wherein a buyer posts what goods or services they require which attracts potential suppliers or service companies to offer their bids with progressively lower prices. The contract is eventually awarded to the supplier or provider who has the lowest price listed in the bid. Reverse auctions are usually used by large companies and the government.

The process of a reverse auction for buyers is as follows:
- Prepare for the auction: what procurement requirements need to be listed, scope, and criteria
- Invite suppliers to participate, this can be done via online auction platforms or specialised platforms. The buyer invites a group of specific suppliers that meet their requirements.
- Auction parameters – buyer arranges parameters of the reverse auction such as start and end times, starting prices, and any other rules that may apply.
- Monitoring the live bidding – and respond to queries as and when they occur.
- Evaluation – Buyers evaluate bids mostly based on price but on other factors stated in the criteria as well.
- Contract award
