Packaging records / source evidence / state reporting

Packaging reporting should be reproducible.

Westover EPR connects packaging records, source documents, calculations, and state requirements into one review-ready reporting system.

Westover EPR is designed so each material total in an approved preparation record can be traced through its sales record, packaging version, component measurement, source, calculation snapshot, and human approval.

01 / Packaging records

Build the packaging ledger before you build the report.

Capture products, SKUs, components, material categories, suppliers, packaging levels, and effective dates in a record that can survive a packaging change halfway through a reporting period.

02 / Evidence and provenance

Replace the scavenger hunt with a source index.

Link supplier declarations, customer confirmations, measured values, imported rows, and expert determinations to the exact facts and conclusions they support.

Initial review architecture

Structure each jurisdiction as a dated review record.

The initial product architecture covers California, Oregon, Washington, Colorado, and Maryland preparation workflows. This is not a determination that a company is obligated in a state or that every state-specific legal rule is implemented.
