Overview
Fleet reporting could summarize approved vehicle-related costs and mileage by entity or period. A finance report should not imply real-time location or operational driving analysis.
Key concepts
Define ownership scope, eligible expense states and distance units. Keep personal-vehicle claims distinguishable from company-vehicle costs.
Implementation considerations
Synthetic report values are examples only. Reconcile source claims and avoid counting both a mileage allowance and the same underlying cost twice.
Illustrative data model
This local fixture shows a possible representation for the concepts above. It is not an endpoint response, production configuration or a claim that the described capability is implemented.

}Design review checklist
- Document which organization owns the fleet reporting representation and which actor may view or change it.
- Test the boundaries of vehicle id, subsidiary id, start date, end date, metric using synthetic values, including missing or inconsistent references.
- Before future implementation, obtain an approved contract and review failure behavior. This documentation does not authorize production activation.
Proposed data types
| Name | Type | Description |
|---|---|---|
| vehicle_id | string | Stable fictional vehicle reference; not a secret and not evidence that a resource exists. |
| subsidiary_id | string | Stable fictional subsidiary reference; not a secret and not evidence that a resource exists. |
| start_date | string (date) | Synthetic calendar date in YYYY-MM-DD form; period inclusivity must be defined by the future contract. |
| end_date | string (date) | Synthetic calendar date in YYYY-MM-DD form; period inclusivity must be defined by the future contract. |
| metric | string | Illustrative metric value; interpret it only within the proposed topic-specific model described above. |
