An insurance core system is the main software of an insurance company. It writes every policy the insurer sells, collects the premiums, and records and pays every claim. It is the insurer's equivalent of a bank's core banking system. Like banks, most insurers buy their core from software companies rather than build it themselves.
The core has three main parts, which are often sold together as one suite. The policy administration system creates each policy and records every change to it. Premium billing collects the premium, the regular payment for the insurance, and follows up when a payment is missed. Claims management records every loss that a customer reports and pays the agreed amount. Life insurers often use a separate core for life and annuity policies, because those policies run for decades.
Consider a family that insures its flat in Kochi against fire and flood for ₹6,500 a year. The policy administration system creates the policy with the flat's address and value. Billing collects the ₹6,500 through a payment gateway. In the monsoon, water damages the flat's floor and furniture. The family reports the loss, and claims management opens a claim. After the damage is assessed, it pays ₹82,000 into the family's bank account. All three parts read and write the same policy record.
Policies reach the core from many places. They come from an agent's insurance agency management system, from an insurance comparison marketplace, or from a checkout that sells embedded insurance. The core also sends figures to the regulator through regulatory reporting software.
Each insurance product needs thousands of rules: who may buy it, how its price is calculated and what it covers. In America, the rules must also match what the insurer filed with each state's regulator. Changing these rules in an old core is slow and expensive. AI models now read a new product's filing and draft its rules, and an employee checks them. Many insurers are also moving from old cores to new cloud cores, much as banks do in core banking modernisation. Several of the largest insurance core systems are built by engineers in Bengaluru, Mumbai and Delhi.
