Manual billing workflow

How to find and download OpenAI invoices

First identify ChatGPT versus API billing: use ChatGPT Settings or Workspace settings > Billing > Invoices for ChatGPT, and the API Platform Billing section or Billing history for API payments.

Step by step

Download the invoice from OpenAI

  1. 01

    Identify whether the charge is for ChatGPT Plus/Pro, a ChatGPT workspace, or the OpenAI API.

  2. 02

    For Plus or Pro on the web, open ChatGPT Settings > Account or Billing, select Payment > Manage, and open Invoice History.

  3. 03

    For ChatGPT Business, open Workspace settings > Billing > Invoices as a workspace owner.

  4. 04

    For API billing, sign in to the API Platform as an organization owner and open Billing or Billing history.

  5. 05

    Download the available invoice or receipt for the relevant payment period.

  6. 06

    For Apple or Google subscriptions, use the app-store purchase history instead of the OpenAI web portal.

Older documents

Where historical invoices are stored

Separate ChatGPT account/workspace billing and API Platform Billing history; app-store history for mobile subscriptions.

Missing evidence

What to do if an invoice is missing

Confirm the product, account, workspace, API organization, and purchase channel. Enterprise API invoices can take up to two weeks after month end, while app-store receipts remain with Apple or Google; contact OpenAI Support if the correct portal is empty.

Troubleshooting

Common retrieval problems

  • ChatGPT and API charges are searched for in the same billing portal.
  • The user is signed in to the wrong ChatGPT workspace or API organization.
  • A mobile subscription receipt is expected on the web.
  • A self-serve API payment is expected to produce an Enterprise-style monthly invoice.

Reconciliation

Match the invoice to a card or bank charge

  • Classify the product and organization before matching the amount.
  • For API spend, distinguish prepaid credit purchases, automatic threshold charges, and Enterprise month-end invoices.
  • Match workspace or organization, document date, and total rather than relying on the OpenAI name alone.
