An **invoice** is a uniquely numbered, dated list of sold items and services issued to a customer. Invoices are produced automatically on subscription renewals and on demand via [Generate Invoice](https://www.fenerum.com/en-DK/docs/api/account.md#generate-an-invoice-for-an-account).

`GET /api/v1/invoices/` (schema: https://app.fenerum.com/api/swagger/?format=openapi)

## Field notes

**`pdf_base64`** — present on the detail endpoint (`GET /api/v1/invoices/{uuid}/`) only. The list endpoint omits this field to keep responses small.

**`status` values**:

- `open` — issued, not yet due.
- `due` — past `due_date`, still unpaid.
- `paid` — fully settled.
- `nonpayment` — flagged as uncollectible.

**Filtering by date** — the `since` query parameter is deprecated. Use `date__gte=YYYY-MM-DD` (and the analogous `date__lte`, `created_date__gte`, `due_date__gte` parameters) to filter list results.
