The term 'rollback' refers to removing the processing of payment within the system using an offline payment method. 

These payment methods include: Cash, Cheque, Eftpos or Complimentary which means that the 'Rollback' function doesn't work for any credit card payments and can only be done for payments processed by admin users. 

It is also important to note that the rollback function is only available to offline payments that are yet to be invoiced. If the specific payment has already been invoiced, the rollback button will disappear entirely.

To action a rollback, you'll first need to open the relevant payment. You can get to this either via the participant search or most efficiently through the payment search. 

Once you've opened the payment and are on the 'Payment Details' page, your page will look like this. 

From here, scroll to the bottom of the page and simply click 'Rollback'. 

You'll then be asked to confirm that you're wanting to process a rollback via a pop up. Once confirmed, the rollback will be processed and you'll be taken to the Payment Search page and a green banner will show "Rollback is successful" and just like that- you're done! 

Note: Once this has been actioned, the charge items will go back to showing as 'unpaid' and the participant status may change if the registration fee was included in the offline payment that was rolled back.
