Log heavy equipment usage hours directly from machinery telemetry and generate billing automatically from that verified data. When a machine is shared across multiple contractors on one site, each is charged for the hours the sensor actually recorded rather than a disputed estimate.
Convert raw machine telemetry into signed, per-contractor billing that no party can contest.
01.
Each machine's telemetry unit is registered with a hardware key. Usage records are signed at source, so a billed hour is provably from the sensor rather than a manual logbook.
02.
External Data Oracles stream engine-on hours and operator identity to the contract, building a per-contractor usage tally that updates continuously through the shift.
03.
The Invoices and Billing module converts verified hours into a rate-carded invoice the moment a billing period closes, with no manual meter reading or reconciliation.
04.
When several contractors share one machine, the ledger apportions cost strictly by the hours each operator's credential logged, ending arguments over who used it longer.
05.
The record distinguishes productive hours from idle and breakdown time, so a contractor is never billed for hours the machine sat unusable.
06.
Any gap or rollback in the telemetry stream is flagged on-chain, making meter tampering or after-the-fact edits immediately visible to both hirer and owner.
Follow a shared excavator from sensor registration through per-contractor usage to an automatically generated invoice.

Cerulea decomposes equipment billing into modular contracts. Each layer attests the meter, records usage, reconciles the period, and invoices without any party editing the underlying hours.
Sensor-verified usage billing is a horizontal capability. Here is how different equipment stakeholders put the automated meter to work.
Bill every hirer from signed telemetry instead of shift logs, cutting revenue leakage from under-reported hours and ending the reconciliation calls at month end.
Key Asset Types
Pay only for the productive hours their own operators logged on a shared machine, with idle and breakdown time transparently excluded from the bill.
Key Asset Types
Draw plant costs straight from verified usage into project cost reports, giving an auditable line between machine hours on site and money spent.
Key Asset Types
Whether you are bridging fleet telematics platforms or capturing hours from a machine's onboard unit, Cerulea routes both into one signed billing record.
For rental firms on established telematics platforms. Machine usage feeds translate into signed on-chain usage records through the API gateway automatically.

The legacy timeline reflects IoT and billing integration benchmarks. Attesting each meter, streaming verified hours, and building multi-contractor invoicing 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 metering and billing rules into pre-audited WebAssembly binaries and provisions the oracle and invoicing layers instantly.
