The anticipated period of performance starts August 28, 2026, through August 27, 2027, with four one-year option periods. The government is only purchasing maintenance services, not new software development. Interested parties must demonstrate capability to satisfy the requirement, with responses due by 4:00 PM Eastern Time on May 11, 2026. No budget amount is specified, and the location for performance is not mentioned.
