# What is missing before profit is trustworthy

`POST /pnl/costs/coverage`

The SKUs that sold and the products that shipped samples in this window with no cost on file, ordered by how many units each one represents — the worklist for making ``POST /pnl/profit`` complete, biggest impact first. ``coverage_pct`` is by units, not by SKU count, so one missing best-seller outranks fifty missing long-tail SKUs.

## Request body

- PnlCostCoverageRequest — POST /pnl/costs/coverage request body — what is still missing.
  - `start_date` string, date, nullable — Inclusive window start (YYYY-MM-DD).
  - `end_date` string, date, nullable — Inclusive window end (YYYY-MM-DD).
  - `sample_basis` 'shipped' | 'approved' | 'requested'
