OpenAI flexible billing

OpenAI has rewritten how large ChatGPT workspaces pay, letting Business, Enterprise, and Edu customers sign annual deals that bill monthly instead of all at once. (help.openai.com) The new help documentation says those plans can use an annual commitment with monthly invoicing, and OpenAI can add a true-up charge when a workspace goes above its contracted seat count. The article was crawled in April 2026 and also notes new “standard ChatGPT” and “Codex-only” seat types for Business and Enterprise as of April 2, 2026. (help.openai.com) OpenAI also drew a sharper line between its two billing systems. Its billing guide says ChatGPT at chatgpt.com and the application programming interface at platform.openai.com are separate platforms, with separate charges, billing history, and workspace or organization settings. (help.openai.com) That distinction addresses a common point of confusion for companies buying both products at once. A paid ChatGPT workspace does not automatically include application programming interface usage, and being added to a ChatGPT Enterprise workspace does not automatically grant access to the application programming interface organization with the same email address. (help.openai.com) OpenAI is also treating ChatGPT Business more like a workplace software product that changes every few weeks. The company now maintains a dedicated ChatGPT Business release-notes page, published last week and updated yesterday, with dated entries for features such as shared Outlook mailbox actions and shared calendar actions. (help.openai.com) The pricing page shows why billing mechanics now matter more than they did when ChatGPT was mainly a consumer subscription. OpenAI sells ChatGPT Business as a per-user workplace plan, while ChatGPT Enterprise is sold through sales, and the public plans page says Enterprise customers can use invoicing rather than only credit cards. (chatgpt.com) The flexible-pricing document also ties billing to feature access. It says credits can unlock extra use of tools such as Deep Research, Thinking models, image generation, Advanced Voice, and Codex, with usage models that vary across Business, Enterprise, and Edu plans. (help.openai.com) OpenAI has kept a public changelog for ChatGPT itself for years, but the company is now doing the same for the business workspace product. The main ChatGPT release-notes page was updated 10 hours ago, while the separate Business notes track admin and workplace integrations on their own timeline. (help.openai.com)
