DFAS General Accounting & Finance System - Modernization (GAFS-M)

The Defense Finance and Accounting Service (DFAS) is conducting market research through a Request for Information (RFI) to identify qualified vendors capable of modernizing its General Accounting & Finance System - Modernization (GAFS-M). This RFI, issued under solicitation number RFIHQ04230626 with a NAICS code of 541519, is strictly for acquisition planning and does not constitute a solicitation or obligate the government to award a contract. Vendors are requested to provide non-binding Rough Order of Magnitude (ROM) estimates and demonstrate their ability to refactor and migrate the existing Unisys mainframe COBOL 74 system to a modern technology stack such as Java, Python, or HTML within a Defense Information System Agency (DISA) or IL-7 DoW accredited cloud environment. The system must maintain or exceed the original system’s accuracy in transaction processing, summation, and account balancing, deliver user response times of no more than 2 seconds for screens and 5 seconds end-to-end, achieve 99.5% annual uptime, and process large batch files within five minutes. All deliverables must be Section 508 compliant, support role-based access controls, handle classified IL-7 transactions, and be fully turned over to the government for sustainment. The work must be developed in an on-premise or IL-5 environment and subjected to STIG compliance scanning using HP Fortify or similar tools with zero CAT I or II vulnerabilities. Internal controls must align with the Risk Management Framework (RMF) and Federal Information System Controls Audit Manual (FISCAM), and personnel involved must hold at least a Security+ certification. The government strictly prohibits the use of any provided data, code, or artifacts to train or enhance any vendor AI, ML, or LLM systems. Vendors are required to submit responses via email by June 17, 2026, at 12 PM ET, limiting submissions to five pages and including mandatory identifiers such as CAGE code, UEI, Small Business status, and contact information. Submissions must also include three recent, relevant contracts with details on scope, value, and performance. Responses will not be accepted as offers, and no reimbursement will be provided for preparation costs. The anticipated place of performance is Indianapolis, Indiana, although the overall period of performance remains unfinalized.
