# List companies the authenticated user may bill a signing to.

`GET /epost/signing/billing-companies`

## Request

- Base URL: `https://api.klara.ch`
- URL: `https://api.klara.ch/epost/signing/billing-companies`
- Auth: one of:
  - API key in header `X-API-KEY`
  - HTTP bearer

Returns the companies the authenticated user is allowed to charge a signing request to — i.e. where the user holds the <code>DOCUMENT_SIGN_BILLING</code> company role in the KLARA web client role system. Used by the UI to render the selection. A user can hold the role in several companies. The returned <code>companyTenantId</code> values are valid inputs for <code>billToCompanyTenantId</code> on <code>POST /signing/processes</code>. luz-documentSign only checks the role and holds no own mapping; revoking the role later does not affect already-submitted processes.

## Response `200`

Companies the user may bill to.

- BillingCompany[]
  - `companyTenantId` string: Tenant id of the company. Pass this value as <code>billToCompanyTenantId</code> on submission.
  - `name` string: Company name — display value only.
