Principia College PrinBill Guide

PrinBill is Principia’s online bill payment service. Monthly billing statements must be viewed online. Payments can be made electronically with secure online access from a U.S. checking or savings account or by credit card. No paper billing occurs with PrinBill, so you must be on the lookout every month for PrinBill e-mail notifications.

Student Login

College students access PrinBill through their BannerWeb account with their personal, secure login. New students will receive their login and password information during the college admission process.  Continuing students will use their existing BannerWeb login and password to access PrinBill.  Please remember to protect this login as it provides access to any stored account numbers.  

Authorized User Login—Parent Access

College students may grant authorized user access to parents and/or other family members or friends assisting with payments. Students can grant authorized user access by going to the Authorized User link on the student home page of their PrinBill account and entering the person’s email address. The personal secure Authorized User login and temporary password will be emailed to that person. This access must be authorized by the student for PrinBill information only, and does not allow access to grades, registration or other student information.  

Monthly Billing Statements

Important:  The “New PrinBill eStatement Available” e-mail summary you receive each month is NOT the actual monthly statement.  You must log in to the student PrinBill account to view the statement which includes all account details. Billing statements are generated on the last business day of each month. Up to 18 months of monthly billing statements are available in the drop down menu.

Payment Methods

Available online payment methods include electronic bank withdrawals (ACH debits) and credit cards. Credit card payments incur a convenience fee of 2.85% ($3.00 minimum per transaction). There are no fees for paying by electronic ACH, and this is Principia’s preferred payment method.

Monthly Installment Payment Plan

College charges may be paid over four months during the college semester.  There is no fee for the use of the installment plan. The payment plan starts in August, with the first payment due by August 15. Each subsequent payment is due by the 15th of the month. A late charge of 1% will automatically apply to accounts for installment payments not received by the due date. 

Payment Plan Due Dates:

Fall Semester
August 15
September 15
October 15
November 15

Spring Semester
December 15
January 15
February 15
March 15

***The student or the authorized user who will be making the payments on the PrinBill account should be the one to enroll in the payment plan each new semester***

Important: If the authorized user wishes to receive all PrinBill email late notices and reminders he/she must enroll in the payment plan by August 10.  After that date our office will automatically enroll the student and authorized users may not receive PrinBill late notices and reminders.

Charges added to a PrinBill account will be included in the payment plan. If charges are incurred during the semester they will be added to the plan and spread out over the remaining months of the payment plan. Note: New charges added to accounts during the semester will increase all remaining unpaid monthly installments resulting in larger monthly installments for the remainder of the payment plan.

International Payments

Options for international payments include wire transfer, credit card, or checks payable in U.S. dollars. For wire transfer instructions and answers to any questions you have about international payments please contact Billing Services.
