The Certified Payments STI Interface website imposes a 20 minute time limit for you to respond to each page during the payment process. You have taken longer than 20 minutes to respond to a page and so you will need to start the payment process again. Please close and re-open your browser.

After submitting a payment, hitting the back button and re-submitting your payment information may result in duplicate electronic check payments. If you are unsure if your payment has been processed, you may review your payment history at www.CertifiedPayments.net by selecting Search Now under Review Payment History.
