# Customer Statement

`GET /companies/{company_id}/ar/customers/{counterparty_id}/statement`

## Request

- Base URL: `https://app.zeno-works.ch` (the document declares no server; this is the origin it was published from)
- URL: `https://app.zeno-works.ch/companies/{company_id}/ar/customers/{counterparty_id}/statement`
- Auth: none declared

One customer's open items + totals (the aging row's drill-down).

``as_of`` mirrors ``GET …/ar/aging`` — set, it reconstructs the items open at
that date so the statement agrees with a historical aging report.
