FAQs
What is ISI Core and how is it different from other policy administration systems?
ISI CoreTM is a unified insurance platform that brings policy administration, underwriting, billing, claims, accounting, reinsurance, analytics, and portals together in a single system. Unlike PAS solutions that rely on multiple add-ons or loosely connected modules, ISI CoreTM uses one data model with real-time financial posting across the insurance lifecycle. This reduces complexity, improves accuracy, and helps insurers launch products and make changes faster with a lower long-term cost of ownership.

Is ISI Core the same as ISI Enterprise?
Yes. ISI Enterprise was rebranded as ISI Core in 2025. While the name has changed, the platform continues to deliver integrated policy, billing, claims, accounting, reinsurance, analytics, and configuration capabilities under the ISI Core brand.

ISI Core combines property and casualty insurance software capabilities with a connected architecture that brings policy administration, billing, claims, accounting, and reinsurance together in one platform.

Can ISI Core be tailored to our workflows and products?

How does ISI Core ensure smooth upgrades and platform evolution?
ISI CoreTM follows a structured release roadmap supported by backward compatibility and controlled upgrade paths. Enhancements are informed by P&C insurer input through ISI’s Customer Council.

How does ISI Core improve operational efficiency for P&C insurers and MGAs?
ISI CoreTM supports operational efficiency by automating key processes across rating, underwriting workflows, billing schedules, document generation, claims routing, financial posting, and reinsurance calculations.
