Most core insurance systems stop at billing and hand the numbers to an external ledger. SISos carries every policy, claim, commission and reinsurance movement through to the general ledger inside one system — which is what turns IFRS-17 and regulatory reporting into a query rather than a reconciliation project.

Accounting in SISos is a module of the core, sharing one data model with underwriting, claims, finance, commissions and reinsurance. There is no nightly extract, no mapping layer, and no second chart of accounts to reconcile. A reserve movement and its accounting entry are the same event, recorded once.
Dynamic accounting posts entries as business events happen, across every line of business held in the same instance — life, non-life, health, annuities and pensions. IFRS-17 measurement, regulatory accounting reports, KYC, AML and the actuarial engine all read that same ledger. The figures in a filing and the figures in the core are the same figures.


A core built for a single line of business can add an accounting module and still be a single-line core. A core that hands off to an external ledger can improve the handoff, but the handoff remains. SISos was built command-based and API-first, across all lines, with accounting inside the boundary — the 11th generation of a suite in continuous development for more than 30 years. That is a property of the architecture, not an item on a roadmap.
