SaaS insurance software, or software-as-a-service, is a model in which the provider handles updates, upgrades, and patches. For insurers, that moves the work of keeping core systems current from internal IT teams to the vendor. Insurers already feel the pressure to make that move, driven by aging systems, costly upgrades, and a growing list of capabilities the business wants. Every insurer knows the cycle. A core system runs for years, a major upgrade becomes unavoidable, and the project absorbs downtime, budget, and the attention of the IT team. Then it’s time for the next upgrade and it starts all over again. What SaaS Means for Insurance Software Insurers comparing cloud vs on-premise insurance software weigh three deployment models. On-premise systems run on infrastructure the insurer owns and manages. Cloud-hosted systems run in a provider’s managed environment, but the insurer still handles updates, upgrades, and patches. SaaS systems also run in the provider’s environment, and the provider takes responsibility for keeping the software current. That last difference shapes who does the work. In a cloud-hosted model, the insurer’s IT team still schedules and tests each upgrade. In a SaaS model, the provider releases updates on a shared platform. SaaS is designed for multitenancy, meaning one software product serves many clients. Development effort focuses on a single codebase, which reduces compatibility problems and spreads the cost of improvements across the client base. For a mid-sized carrier, that design matters. Capabilities such as analytics and AI arrive through a subscription the vendor maintains, which lets the carrier access what once required a multiyear internal build. Where Insurers Stand on Core Modernization Insurers are already moving. Adacta surveyed more than 100 senior executives at European insurers between October and December 2024. Its 2025 findings show that 51.8% of organizations are engaged in core system modernization projects, and another 27.3% plan to begin within 12 months. Of the approaches under consideration, 58.1% favor replacing legacy systems with a single unified system covering policy administration, claims, and billing. North American carriers show similar pressure. BriteCore’s 2025 report, based on 60 P&C carriers, found that two-thirds see modernization as essential to staying competitive, and only 56% are satisfied with their current systems. BriteCore sells cloud-native core platforms, so its findings reflect a vendor’s view of the market. Market estimates point the same direction. TrendX puts the global P&C core insurance software market at about $9.45 billion in 2025, growing roughly 9.4% a year. It attributes much of that growth to carriers moving from legacy mainframes to API-first SaaS platforms. Interest in insurance core systems SaaS is growing for that reason. How SaaS Changes the Cost of Running Systems A core system’s cost extends well beyond its license. In on-premise and cloud-hosted models, the insurer pays for infrastructure, IT staff, and periodic upgrade projects. Each upgrade requires testing, downtime planning, and internal resources that could otherwise support underwriting, claims, or product development. SaaS changes the structure of those costs. The insurer pays a subscription, and the provider carries the infrastructure and most of the upgrade work. Budgets become easier to plan because upgrades no longer arrive as large, unscheduled projects. The savings depend on how the insurer uses the platform. Configuration within the vendor’s supported settings lets updates arrive with little disruption. Heavy custom code brings back the upkeep SaaS was meant to remove, because each custom change must be retested against every release. For example, a regional carrier might build a custom claims workflow directly into its core system. Each vendor release triggers a review of that code, and internal developers return to the upgrade cycle. A carrier that meets the same need through configuration tools receives updates with far less internal effort. What to Weigh Before Moving to SaaS Moving to SaaS changes the operating model, so a few questions clarify fit. Ask about the provider’s release cadence and how it communicates changes, because that schedule shapes the insurer’s testing plan. Ask how much work the platform handles through configuration and how much requires custom development, since that determines how much upkeep stays internal. Review data migration and integrations early, because they often set the timeline more than the software does. Finally, ask how the provider manages security, including its certifications and incident response. Origami Risk’s policy, billing, and claims solutions are cloud-native and run on one connected platform for risk, insurance, and compliance, so insurers can evaluate each function on its own timeline. Insurers that treat SaaS as a way to shift upkeep to the provider get the most from the decision. Insurance is moving toward faster product changes, new data sources, and AI-driven decisions. Insurers that define their update requirements now will be better positioned to choose a platform that keeps pace. Download the guide to see what future-proof really requires for insurance platforms. Frequently Asked Questions What is SaaS in insurance? SaaS, or insurance software as a service, is a subscription model in which the software provider manages updates, upgrades, and patches. Insurers use it for core functions such as policy administration, billing, and claims without maintaining the underlying infrastructure. How is SaaS different from cloud hosting? In cloud hosting, the software runs in a provider’s environment, but the insurer still schedules and manages updates. In SaaS, the provider manages the software itself, so the insurer’s IT team can focus on integrations, data, and business needs. Learn more about the difference here. Why are insurers moving core systems now? Aging systems make major upgrades costly and disruptive. A 2025 Adacta survey found that about half of the organizations it surveyed were already in core modernization projects, and the growing need for new data sources and AI capabilities adds urgency. Does SaaS reduce the need for internal IT support? Yes, for software maintenance. The provider handles upgrades and patches, which frees internal IT to support integrations, data quality, and the business teams that depend on the system. What should insurers ask a SaaS vendor? Ask about release cadence, how configuration differs from custom development, data migration support, integration options, and security certifications. The answers show how much upkeep will stay internal after the move. Is SaaS a fit for smaller insurers? For many, it is. Subscriptions give smaller carriers access to advanced capabilities without building the infrastructure and internal IT staff those capabilities require.
