The United States Postal Service Office of Inspector General (USPS OIG) is soliciting proposals through its Fiscal Year 2025 Broad Agency Announcement (BAA) for professional, consultant, and support services aimed at enhancing OIG operations. This BAA, which supersedes all prior announcements, invites submissions on a rolling basis for various services, including legal counsel, research solutions, investigative support, auditing, IT services, and mission support functions, with the potential for contract awards throughout the solicitation period. The initiative is crucial for advancing transparency and accountability within postal services, and all proposals must comply with specific evaluation criteria and legal provisions, including the Vietnam Era Veterans' Readjustment Assistance Act for contracts exceeding $150,000. Interested parties can reach out to USPS OIG Contracting at contracts@uspsoig.gov, with the solicitation period running until September 30, 2025.
