About this file

This is a Single Source Determination for Commercial Product or Service issued by the Department of the Interior's Interior Business Center on behalf of the Office of the Chief Information Officer.

The solicitation (140D0426Q0805) seeks renewal of Treehouse Software licenses and maintenance to support critical operations within DOI's enterprise personnel and payroll systems. The software suite comprises three integrated components: N2O (manages Federal Personnel and Payroll System data between development/test environments and provides auditing), Auditre (interrogates Mainframe Adaptable Database System protection logs for auditing and research), and tRelational/DPS (maps ADABAS data to Oracle database targets and extracts information to datamart systems). The contract period runs from October 1, 2026, through September 30, 2027, with four optional one-year renewal periods extending through September 30, 2031. The contracting officer has determined that only Treehouse Software Inc. (located at 2605 Nicholson Road, #1230, Sewickley, PA 15143) is reasonably available as a single source based on exclusive licensing and proprietary data restrictions, compatibility with existing systems, and the absence of alternative vendors capable of meeting federal financial audit and data traceability requirements. Market research of GSA Advantage, NASA's SEWP contract vehicles, and GWAC found no competing products offering equivalent functionality as an integrated suite. The determination was certified by Contracting Officer Maria Norfleet on August 7, 2026.
