Turn any product into a live auction. Bids land in real time and the winner is invoiced for you.
Hammerdown turns any product in your catalog into a timed auction, without moving your store anywhere else. Shoppers bid from the product page and watch every bid land in real time. Buyers can set a private maximum and let the app bid on their behalf. A bid in the closing seconds pushes the end time out, so an auction ends when the bidding does. When it closes, the winner is invoiced automatically at the price they won, and the product cannot be bought at its catalog price by anyone else.
