When someone registers online and makes an optional donation during the registration process, they are limited to paying immediately by credit card. Immediate payment is required, as a tax receipt is automatically issued for the amount of the donation after the registration process has been completed.

The system is designed to prevent your organization from issuing a tax receipt, when you have not yet received payment for the donation.

If a registrant wishes to pay by cheque, then they should not make an additional donation during the registration process.
