ISI utilizes Invoiced billing and portal solutions to generate monthly invoices, enable autopay for payment plans, and give families the ability to view invoices and make payments online.

about INVOICEd

Billing Cycle

The Invoiced system provides a more predictable billing cycle. 

  • Monthly payers will receive invoices on the fifth of each month
  • Semi-annual payers receive their invoices on June 5 and November 5 
  • Annual payers will be invoiced June 5

Electronic Invoices

All invoices are issued electronically via Invoiced.  

Each ISI student has at least one parent/guardian set up as an authorized payer. Authorized payers will be notified of all bills with an email notification from to the email address on file with the registrar (reflected in your SchoolAdmin account).

Invoice emails will contain a securely generated URL, known as a “magic link” to sign authorized payers into their family’s account. By first clicking the button that says, “view invoice” followed by “pay now” you will be able to proceed to your payment portal.

How to Access your Invoiced Account 

Authorized payer(s) can visit the ISI Invoiced portal directly at and request a sign in link by simply entering in the email address utilized by ISI. You will then receive an email from Invoiced with a Sign In button. We will only send a sign in link to the email address that is on file with the ISI Business Office and where invoices are currently being sent.
