     * on advance invoices, including eligibility on generating one; for the most part, they function like
     * any other invoice, except they are issued early and have special behavior upon being voided.
     * A subscription may only have one advance invoice per billing period. Attempting to issue an advance
     * invoice when one already exists will return an error.
     * That said, regeneration of the invoice may be forced with the params `force: true`, which will void
     * an advance invoice if one exists and generate a new one. If no advance invoice exists, a new one
     * will be generated.
     * We recommend using either the create or preview endpoints for proforma invoices to preview this
     * advance invoice before using this endpoint to generate it.
