Most events do not have "Transition to Live Auction" enabled. Rather, at the online auction close time, TravelPledge Auctions automatically sends each winning bidder their invoice.
Suppose, however, that you want to accept online bids for a period of time, after which you will promote some or all of the items to in-person attendees with a live auctioneer.
Before your bidding period:
In your Auction Settings, check the box for "Transition to in-person auction."
Finalize your other Auction Settings and save.
Upload your auction items and share your Auction Site with supporters.
After your bidding period:
TravelPledge Auctions automatically disables online bidding at the end of your auction period. After which, an auctioneer then presents one or more auction item to your in-person audience, where they bid via paddle raise or other "offline" method.
For each item that fetches an "offline" bid, record the winning bid manually in your TravelPledge dashboard.
Once you've recorded all your "offline" winning bids, return to your Bid Report and click Close in-person bidding and send invoices. This will send each winning bidder their invoice.
