How does credit card pre-authorization work?
The pre-authorization checkbox is located on Setup > Payments.
How it works
If pre-authorizaion is enabled participants will be required to connect a digital wallet or enter credit card details before placing a bid in an auction or making a donation or purchase on an item where pay now is disabled.
Pre-authorization is not applicable to buy now items such as raffle tickets as payment is required at the point of purchase.
To check if pre-authorization is enabled on your campaign and to edit the setting go to Setup > Payments.
Note that credit cards are not automatically charged when the campaign closes. By default, notifications (including a link to pay) will be sent to participants with amounts owing. Proccessing payment is a one click process for participants. Alternatively they can choose to pay using a different card/method.
If required, end of campaign notifications with payment links can be disabled in Auction Controls.
How to manually charge cards
Note: The feature to manually charge participants cards is only available on the 4.9% Software Fee pricing option
Campaign administrators can charge individual credit cards manually. You may need to upgrade your GalaBid account to charge cards.
This is the process. Go to the Checkout Console, search for the winner name. If the card is already on the account 'Charge card' will appear next to the participant's name and clicking this will charge the card on their account.

Alternatively, you can click VIEW INVOICE to charge the pre-authorized payment method.

Best Practice Communication with Participants
Campaign administrators planning to charge credit cards manually should alert campaign participants by adding information about the process to the Terms and Conditions and or Item Descriptions. Edit Terms and Conditions in Setup > Registration. Here is an example of the potential wording.
When participating in this campaign you will be required to connect a digital wallet or add a card before placing a bid. At the auction close you will receive a link to view and pay your invoice. Note that credit cards are not automatically charged however, the auction manager reserves the right to process any payments outstanding more than 72 hours after the auction has closed.
Legal Considerations
Note that GalaBid is not able to provide legal advice. Consult a legal professional in your state or country to ensure you are comply with local laws.
