Citadel Security Systems
Online Bill Pay Service

Welcome to Citadel Security Systems' online bill pay service! The button below will take you to a secure third-party server set up specifically to process credit card transactions on behalf of Citadel. Please have your invoice ready to reference bill amount, ARS customer #, and invoice number, as well as your means of payment. We accept Visa, Discover, MasterCard, and American Express. If you would like a receipt, feel free to enter your email address; it is not required simply to submit a payment.


We will never, under any circumstance, save your credit card information.


If you have any questions, or would feel more comfortable giving us your payment information directly,
please feel free to call our office during business hours at 215-357-3434.
