A filing-ready package is not a spreadsheet of guesses. It is nine artifacts, each with evidence and version control, closed by a written client certification.

The nine deliverables

1. Normalized packaging bill of materials — one row per separable component per configuration version, mass in grams with evidence and confidence.
2. State-specific assumptions supplied or approved by the client or counsel (producer entity, scope, exclusions).
3. Category mapping with rule citations and version dates per component per state.
4. State-supply aggregation and reconciliation — units by destination state and channel.
5. Fee estimate or range where a usable schedule exists, labeled current-schedule, illustrative, scenario, or unavailable — never “the bill.”
6. Unresolved-issue register with owners (client, counsel, supplier).
7. Draft portal upload/reporting workbook in the PRO’s current template.
8. Client certification/sign-off record covering entities, assumptions, and totals.
9. Evidence archive and change log — originals never overwritten.

The two reconciliations (both must pass)

• Mass reconciliation: product units × component mass equals category totals.
• Commercial reconciliation: reported units reasonably reconcile to fulfillment, sales, returns, and packaging-purchase records.

Then an independent recalculation samples the top five components by fee, top five by mass, all manual overrides, all low/medium-confidence items, and every exemption, credit, bonus, and malus.

Acceptance rule

A package is ready for client approval only when every product maps to a configuration version, every component has mass/material/evidence/confidence, and unresolved legal issues are excluded or answered by counsel. No filing without written client approval of the final data and producer identity.

Data/compliance support only — not legal advice. Method: docs/03-product.md and docs/04-operations.md in this practice.
