If the 26th of the month falls on a Saturday, Sunday or federal holiday, payment requests must be made on the preceding Friday. The Payment Management System will re-open for NASA drawdowns on the first business day of each month. For questions, please contact your NASA Center point of contact or your PMS Liaison Accountant.
