Setting the validity of vouchers
The standard period of time that a voucher is valid for, is an organization setting. The validity of specific vouchers can be edited via the Vouchers index page in the reservations module.
Set default validity period
Go to the 'Other' page in your organization settings. Enter a number of days for 'Voucher validity'.
Here, you can also choose to make vouchers redeemable for all your administrations. This means that a voucher created for a cancelled reservation at one of your administrations, may be applied for a new booking at another of your administrations.
If you leave this input field blank, voucher will have no expiration date.
Editing the validity of existing vouchers
Go to 'Vouchers' in the reservations module. Use the filters and checkboxes to select one or more existing vouchers. Once selected, an 'Edit' button is shown. In the resulting pop-up, the expiration date can be changed.
