I was responsible for SPS and the Payment Automation Manager (PAM) the application or engine that processes payments.

I retired in July of 2024 from Fiscal Service and was the Director of the division having responsibility of the domestic payment applications. What do you want to know?

SPS does have separation of duties. It requires two individuals from an agency to process payments. A Data Entry Operator(DEO) and a Certifying Officer(CO) are required for every payment.
