Starting bids and increment amounts are crucial to maximizing silent auction proceeds.
When creating an auction item, there is a 'Set Pricing' button to the right of the Fair Market Value. This button will pull from two percentages (set in your Fundraiser Settings/Auction Settings section) and auto-populate the starting bid and increment fields.
These are percentages so they won't always look pretty but they give you a starting point. From there, you can edit the values accordingly.
If you're unsure where to start, we recommend a starting bid between 35-50% of value and an increment amount of 10% of value.
