Payment methods

Payments via the internet can be made using either a credit/debit card or an eCheck.  The university accepts Visa, MasterCard, Discover, JCB, and American Express credit cards.  All credit card transactions are charged a 2.95% service fee on the amount of the transaction.  There is a $3.00 minimum service fee.

eCheck payments will require the following information: your bank routing number and your checking account number.  There is no additional cost to pay with eCheck.  We encourage payers to speak with their bank and verify their account numbers.

If you have a LOUIE User ID, use LOUIE to pay charges. This system will immediately post payments to your account.  Holds will be released overnight.

NAU partners with Flywire for students to send international payments to the university.  Flywire offers excellent foreign exchange rates that will help to lower your cost of attending.  As a student you can find the link to Flywire on your LOUIE account by clicking the Account Inquiry/Make a Payment link under the Finances section, or visit the Flywire website.  Flywire offers 24/7 support in multiple languages.

Check payments may be mailed directly to Student and Departmental Account Services.  Please make checks payable to NAU and be sure to include the Student ID Number on the check and mail to:

Paying with a 529 Prepaid or College Savings Plan

NAU accepts payments from 529 Prepaid and College Savings Plans through several convenient methods. Contact your 529 plan to confirm the options they offer:

Electronic Payments

• Preferred method for fast, secure transfers (2–3 business days).
• NAU partners with Flywire for direct electronic payments. Check if your 529 plan works with Flywire.
• Some plans allow payments directly through the student’s LOUIE account. Visit the Transact payment portal under the “Financial Account” tile in LOUIE to check availability. A processing fee may apply.

Paper Check

• Request a check from your 529 company and have it mailed to NAU.
• Include your 7-digit NAU ID number.
• Request funds early—allow at least 2 weeks before the tuition deadline to avoid delays or late fees.

Third-Party Billing

• If your 529 requires an invoice, provide NAU with your plan’s benefits, restrictions, and invoicing instructions.
• Plan benefits should be sent to SDAS@nau.edu.
• NAU currently invoices for:
  • Nevada Prepaid Tuition Program
  • College Illinois
  • Texas Guaranteed Tuition Plan
  • Michigan Education Trust
  • Florida Prepaid College Program

For those whose attendance is sponsored, provide our office with the authorization to bill an outside organization.
