On Bookwhen you can restrict how far into the future a ticket can be transferred to a new event, and also whether multiple transfers are allowed for the same ticket.
Firstly head over to Settings then select Booking Preferences:
Then select Edit on the Cancellation section, then tick the Allow ticket date transfers checkbox to view and amend your transfer settings:
Transfers allowed until - This is the period of time that transferring is allowed before the start date and time of the booked ticket. This can be set as minutes, hours, days, weeks or months.
Restrict transfer window to - This setting is how far into the future a ticket can be transferred from the date of the booked ticket to a new date. This can also be set as minutes, hours, days, weeks or months. For days, weeks or months an additional box to the right appears where you can then select the time of day as well. Either box can be left blank to apply no restriction.
Restrict to one transfer per ticket - Ticking this checkbox restricts your bookers to only be able to transfer their ticket once. Leaving this unticked, the booker can then transfer their ticket multiple times.
Allow transfers to different events or ticket types - Ticking this checkbox allows bookers to transfer their ticket to a different event or ticket on your schedule from the originally booked ticket. Please note, transferring is never permitted to a ticket of a higher cost.
