PROS: Integrated Assessment Technology for Modern Municipal Government

Developed by GAR Associates, the PROS suite of applications helps municipalities modernize assessment operations, improve public transparency, and streamline day-to-day workflows.

Built specifically for local government, PROS integrates directly with municipal assessment workflows and RPS-related processes, reducing implementation complexity while improving data accuracy, operational continuity, and public accessibility. The platform is designed to scale with your office's needs, so additional tools and features can be added over time without replacing your core system.

GAR Associates has decades of experience supporting municipal assessment operations and served as a contributor to the development of New York’s Real Property System (RPS). That experience gives us a unique understanding of municipal assessment workflows — and it’s what shaped the PROS suite of applications.

Why Municipalities Choose PROS

The PROS Suite

An easy-to-use, web-based portal where the public and municipal staff can search and view property records, assessment data, and parcel details in real time. Advanced search and GIS-based mapping tools let users locate properties by address, owner name, or parcel ID — improving accessibility and transparency for taxpayers, real estate professionals, and researchers alike.

Products Designed for Assessment Professionals

Power Appeal

Power Appeal

An online grievance and appeal management platform. Property owners can submit a formal assessment challenge in a user-friendly digital environment, while BAR members can review and respond to appeals online — improving efficiency and reducing costs for the assessment office.

Val Shield

ValShield

A comparable sales analysis tool built for assessment staff. ValShield combines manual and AI-generated adjustments in an intuitive grid interface, letting users select comparable sales and feature adjustments to reconcile value — then generate a report with comps, adopted value, and a map.

PropNexus

PropNexus

A property data auditing, reconciliation, and quality assurance platform. Assessors can capture photos with a phone or tablet and attach them directly to property records — working in real time or offline, with automatic syncing to the CAMA system in bulk. PropNexus drastically reduces the manual hours required to keep inventory up to date.

AVA™ (Automated Valuation Assistant)

AVA™ (Automated Valuation Assistant)

A virtual assistant that delivers conversational answers to property tax and assessment questions. AVA draws on jurisdiction-specific documentation — Q&A guides, public notices, explanatory handouts — to explain concepts like market value, equalization, exemptions, and millage rates, tailoring answers to property type and assessment year.

Maertellus

Maertellus

Maertellus is a powerful commercial market intelligence platform that gives assessors, municipalities, and appraisal professionals access to verified property data, sales and lease comparables, market analytics, and valuation insights—all in one centralized, cloud-based solution.
