Auction software

Auction software is a type of computer program that helps you to run auctions. With auction software, you can set up an auction online, which means that people can place bids on items without having to show up in person. You can also track the bids and see how much money each item is being bid on. The software also stores information about the bidder, such as their name and address. With this information, you can call the high bidder after the auction is finished and let them know they've won the item.
