Stand up automated reconciliation between an employer's actual headcount and the group premium the insurer charges, updated the moment an employee joins or leaves. Civil Registry, Invoices and Billing, and Compliance Attestations keep the enrolled list synchronized so premiums never drift from reality during frequent hiring and attrition.
Turn a manual monthly true-up into a continuous, tamper-evident match between roster and premium.
01.
The Civil Registry module records each joiner and leaver as a signed enrollment event, so the covered list reflects the workforce in real time rather than a month-end snapshot.
02.
Every roster change recomputes the group premium automatically, ending the drift between what the employer pays and who is actually covered.
03.
The Invoices and Billing module prices mid-cycle additions and removals pro-rata, so a hire on day 10 and an exit on day 20 are both billed for exactly their covered days.
04.
Each invoice is anchored to the underlying roster events, so an employer can trace every line to a signed enrollment change instead of contesting a lump-sum bill.
05.
Compliance Attestations confirm that only eligible, active employees appear on the covered list, closing the gap where departed staff stay billed or new hires go uncovered.
06.
Two further Cerulea Studio modules retire the manual monthly reconciliation entirely, replacing spreadsheets and emails with a self-updating shared ledger.
Follow a single roster change from an HR event to an adjusted, anchored premium the employer can trace.

Cerulea decomposes group reconciliation into modular contracts. Each layer records roster changes, attests eligibility, recomputes premium, and anchors invoices without a manual true-up.
Continuous enrollment reconciliation is a horizontal capability. Here is how different actors in group insurance put the shared ledger to work.
Push joiner and leaver events straight from HR and see the group premium adjust in real time, ending the manual monthly true-up and the mismatch between headcount and what is billed.
Key Asset Types
Bill only for eligible, active members on a live covered list, cutting revenue leakage from departed staff and closing the coverage gap for new hires.
Key Asset Types
Administer group accounts against one synchronized roster shared by employer and insurer, replacing reconciliation spreadsheets with a single traceable record.
Key Asset Types
Whether you are bridging an insurer's group billing system or capturing roster changes from an employer's HRMS, Cerulea routes both into one shared reconciliation ledger.
For insurers on legacy group billing platforms. Existing premium and roster records are translated into signed on-chain reconciliation events through the API gateway automatically.

For employers pushing roster changes from HR. A connector signs each joiner and leaver event from an employer wallet and routes it directly to the reconciliation ledger.

Shared Enrollment Record
Building a continuous reconciliation network with live roster sync, pro-rata premium logic, and anchored invoicing from scratch requires specialised engineers and long HR-to-insurer integration cycles. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects group-benefits integration benchmarks. Connecting employer HR systems to an insurer's billing platform, coding pro-rata premium logic, and shipping traceable invoicing for an average network takes a baseline of 6 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your enrollment and billing rules into pre-audited WebAssembly binaries and provisions the shared reconciliation ledger instantly.
