# Invoice Items

Invoice Items represent the component lines of an [invoice](https://docs.stripe.com/docs/api/invoices.md). An invoice item is added to an invoice by creating or updating it with an `invoice` field, at which point it will be included as [an invoice line item](https://docs.stripe.com/docs/api/invoices/line_item.md) within [invoice.lines](https://docs.stripe.com/docs/api/invoices/object.md#invoice_object-lines).

Invoice Items can be created before you are ready to actually send the invoice. This can be particularly useful when combined with a [subscription](https://docs.stripe.com/docs/api/subscriptions.md). Sometimes you want to add a charge or credit to a customer, but actually charge or credit the customer’s card only at the end of a regular billing cycle. This is useful for combining several charges (to minimize per-transaction fees), or for having Stripe tabulate your usage-based billing totals.
