Accounts Payable FAQs

Vendor – General Questions

The Comptroller’s Debt Setoff (CDS) program, also known as the Vendor Setoff program, is authorized by the Code of Virginia, Sections 2.2-4800 through 2.2- 4808. Under the CDS program, payments made to individuals, businesses, and other entities who may owe money to the Commonwealth of Virginia, can be withheld, in full or in part, to satisfy the debt owed the State. The Commonwealth also participates in the federal government-wide debt collection program (TOP). TOP matches individuals and businesses who owe delinquent debts to federal government agencies and recover the debt by offsetting the payment. 

The Commonwealth will not release the details to George Mason University on why part or all of our payment to you was withheld. Please contact the Virginia Department of Accounts or call them at 804-367-8037 or cds@doa.virginia.gov.  For the TOP program, the payee will receive a letter identifying the TOP offset amount and the federal agency(ies) to which the debt was applied. Please check out the following link for more information: https://fiscal.treasury.gov/top/

No. PCO stands for “payment card order,” which means that a payment was already processed using a university credit card (P-Card). If you have questions about a credit card payment please contact the person that placed the order with you.
