# Adds Billie company details and reference properties to Quote Preview Invoices

## What’s new

Adds the [company_details](https://docs.stripe.com/api/quote-preview-invoices/object.md?api-version=2026-09-30.preview#quote_preview_invoice_object-payment_settings-payment_method_options-billie) and [reference](https://docs.stripe.com/api/quote-preview-invoices/object.md?api-version=2026-09-30.preview#quote_preview_invoice_object-payment_settings-payment_method_options-billie) properties to the Billie payment method options on [Quote Preview Invoice](https://docs.stripe.com/api/quote-preview-invoices/object.md?api-version=2026-09-30.preview#quote_preview_invoice_object) objects. These response properties expose Billie-specific company information and the transaction reference in invoice previews.

## Impact

You can now inspect `company_details` and `reference` in the Billie payment method options on Quote Preview Invoice responses. Existing Payment Intent, Invoice, and Subscription request behavior is unchanged. See [Billie payments](https://docs.stripe.com/payments/billie.md) for integration guidance.
