Budget estimate

$500,000 – $3,000,000

Based on typical municipal tax‑software implementations, total contract value is likely to include a multi‑year software license, implementation services, data migration, training, and 24/7 support. Comparable projects in similar U.S. counties range from $0.5 million for a basic license up to $3 million for a fully customized, integrated solution with extensive support. The estimate assumes a 3‑5 year contract term, with licensing fees constituting the larger share and implementation/training comprising the remainder.
