Can I use Sharetribe for a bidding or auction marketplace?
Unfortunately at this time we do not offer this functionality. On a Sharetribe marketplace the price need to be fixed.
Some marketplaces have used the comment section for the listings as a workaround. Users gives their bid as a comment and when the bidding is over the seller contacts the winning user. The seller then changes the price for the listing to the winners bid and only accepts the transaction from the winning user.
If the bidding is silent the direct message system can be used.
