What are net terms?

Net terms is an agreement between two parties that a payment of the entire invoice amount is required within a certain time period. At UC San Diego, payment terms are set with careful consideration. Our terms have been established based on industry standards and are designed to ensure a smooth operation and maintain a fair and consistent approach for all our clients. Our net terms vary on the payment method selected. For example:

Virtual Card - Net 0

Direct Deposit - Net 45

Check - Net 60 

*Note: Payment terms are net from invoice date. 

Please also keep this in mind when you are looking up the status of invoices and payments. The invoice may be validated and approved but a payment will not be issued until the due date (e.g. invoice date is June 1, 2023, is approved by June 20th, but isn’t due until July 15, 2023, so a direct deposit is sent July 15, 2023 for Net 45 direct deposit terms).
