Online Payments

Partnering with the TD eBill Solution allows us to provide you with the flexibility and convenience of paying your bills online. The site is a fully secure electronic payment portal that functions just like any other online payment service. You now have the option of direct payments from your bank account (US banks only) or using your credit card (transaction fees apply).

For a guide on how to use the online payments system, click on our Online Payments Guide.

If you have trouble connecting to the system please try using a VPN service.

Online Product Ordering

ISY also has an online system for making purchases in our Spirit Store, ordering food from vendors and this is also being expanded to allow for donations to be made to projects like the United World Schools Project.  For information on how this works please visit our Online Ordering Page.
