Computer-Assisted Mass Appraisal (CAMA) System

The Montana Department of Revenue is seeking proposals through the State Procurement Services Division for a replacement Computer-Assisted Mass Appraisal (CAMA) system, with proposals due November 17, 2026 at 2:00 p.m. MST. The source names no set-aside or preference program, and no sole-source or cooperative-purchasing requirement.

The State is replacing its incumbent Orion (AT-Pro) system with a modern cloud-based CAMA solution that meets Montana's statutory property tax administration obligations and supports operations for the next 10+ years. The procurement includes product and service line items structured as lump-sum deliverables. Offerors must complete business information documentation, respond thoroughly to the Scope of Services, and comply with Montana's contract terms and conditions. Compliance obligations include verification of nondiscrimination against firearm entities under Montana Code Annotated 30-20-301, disclosure of artificial intelligence use, Montana prevailing wage requirements, and insurance requirements.

Cost proposals must use the provided Cost Proposal Worksheet and its detailed instructions. Payment terms are Net 30 with no prepayment discounts. Responses containing confidential or proprietary information require a Trade Secret Affidavit and redacted copies.

An optional pre-proposal conference is referenced in the RFP file, and the file names Orion (AT-Pro) as the incumbent system.
