The Payment Services division of the Procurement Service Center is comprised of the Payable Services team and the Commercial Card team.

The Payables team is responsible for the processing of all invoice payments against existing purchase orders, processing payments on various forms, and processing reimbursements for eligible business expenses. The team is responsible for auditing and processing all payments in compliance with applicable rules and regulations, and in a timely manner. All invoices, credit memos and other payment forms are processed within 10 business days of submission. 

The Commercial Card team is responsible for administration and maintenance of University-issued Procurement and Travel Cards, as well as monitoring for overall program compliance. The Commercial Card team supports campus departments who approve faculty and staff to apply for and utilize a University-issued credit card. The team processes account applications and updates, advises on compliance and use issues, and periodically audits campus cardholders to monitor and provide feedback on overall department program adherence.
