The Commercial Accounts Receivables Office, within the Office of the Bursar, collaborates with NIU departments to bill outside clients for non-student related charges such as (but not limited to) room charges, catering charges or services rendered. Each department is assigned a unique three-letter "bill type" to distinguish itself on the invoices. If you are unsure of your department’s three-letter bill type, or the setup of the cost center, contact the Commercial Receivables Office.
Customer account numbers for outside clients can be requested by e-mailing a UpdatedRequest to Add/Update Customer Record (XLS). All request forms must be filled in completely and include a telephone number and an SSN, TIN or FEIN for the customer. A SSN, TIN or FEIN is necessary for state and federal reporting purposes.
Invoices are created, usually within a week, after receipt from the department of a UpdatedRequest to Generate a Customer Invoice (XLS). The invoice will contain information referencing the services or items purchased and their related cost. An invoice copy, called a "proforma," will be sent to the billing department to maintain a record of your billings. The department has the option of having Commercial Receivables mail out all of its invoices or having all the invoices returned to the department.
Statements are mailed out the last day of each month. The statements will show any new transactions during the month and provide the current balance due on the account.
