Fleet fuel cards generate transactions across many stations that must be reconciled against expected consumption per vehicle and trip to catch fraud like a driver fueling a personal car. Cerulea anchors each fuel transaction alongside vehicle and trip data, flagging fills that break the expected pattern.
Replace an after-the-fact exception report with continuous, verified fuel-to-trip matching.
01.
Capture every fill at source. External Data Oracles ingest fuel card transactions from each station feed, binding volume, price, and location to the card in real time.
02.
Know what a trip should burn. The contract holds expected consumption per vehicle and route, so each fill is judged against a realistic baseline rather than a flat threshold.
03.
Surface suspicious fills instantly. The Audit Logs module flags a transaction whose volume, timing, or location does not match the vehicle's trip, routing it to an administrator to review.
04.
Reconcile card charges to reality. The Invoices and Billing module matches each fuel charge to the vehicle it was assigned to, exposing fills that cannot be tied to a legitimate trip.
05.
Stop cross-vehicle abuse. Each card is bound on-chain to its vehicle, so a fill at a location the truck never visited is immediately detectable.
06.
Preserve the audit record. Every transaction and flag is anchored immutably, giving finance a defensible fuel history for cost control and fraud investigation.
Follow a single fuel card transaction from the pump through consumption matching to an anomaly flag.

Cerulea decomposes fuel reconciliation into modular contracts. Each layer ingests, binds, evaluates, and records a fill without any single system quietly overwriting the fuel record.
Verified fuel reconciliation is a horizontal capability. Here is how different fleet actors put the shared record to work.
Match every fuel card fill to a real trip and catch personal fueling or skimming as it happens, cutting fuel leakage that manual exception reports miss for weeks.
Key Asset Types
Publish signed transaction feeds fleets can reconcile trustlessly, reducing chargeback disputes and strengthening confidence in card usage across their stations.
Key Asset Types
Book fuel spend from a tamper-evident source tied to vehicles and trips, giving auditors a clean trail and a defensible basis for fraud recovery.
Key Asset Types
Whether you are bridging fuel card provider systems or pulling station transaction feeds, Cerulea routes every source into one reconciled fuel record.
For fuel card and station networks on legacy systems. Existing transaction feeds are translated into signed on-chain fuel records through the API gateway automatically.

Reconciled Fuel Record
Building a fuel reconciliation platform with station feed ingestion, per-trip consumption modeling, and real-time anomaly flagging from scratch requires specialised engineers and long integration cycles. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects fleet fuel-analytics integration benchmarks. Connecting each card provider feed, building custom consumption modeling and anomaly-detection logic, and shipping a review workflow for an average fleet takes a baseline of 7 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your consumption and anomaly rules into pre-audited WebAssembly binaries and provisions the shared fuel ledger instantly.
