Invoice

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.

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.
