# Preview the upcoming invoice for a subscription

`GET /v1/subscriptions/{id}/upcoming-invoice`

Computes what the customer's next invoice will look like, including any
usage charges accumulated so far in the current billing period. Read-only —
no charges, invoices, or line items are persisted.

Tax is computed using the same pipeline as the real invoice generator, so
STRIPE_TAX merchants get accurate previews (at the cost of a tiny Stripe
Tax usage call).

Returns 409 NOT_BILLABLE when the subscription is paused, cancelled, or
already past its period end.

## Path parameters

- `id` string, required
