Overview

OpenAI does not support changes to invoice dates. Billing cycles and invoice schedules depend on your subscription type and billing arrangement.

ChatGPT subscriptions

For a ChatGPT subscription billed monthly:

• Billing recurs on the date you subscribed.

• For example, if you subscribed on the 12th, you are billed again on the 12th of each following month.

• Invoice dates follow that recurring schedule and cannot be modified.

API billing

API billing is not always postpaid. Accounts can use prepaid credits or automatic card payments, while Enterprise API customers receive invoices.

For Enterprise API customers, invoices cover calendar-month usage unless a different custom billing arrangement is agreed in writing. For example, an invoice covering March usage is issued after March ends.

For prepaid credit purchases, see: Prepaid API billing.
