Stripe wants to turn your AI costs into a profit center

Stripe on Monday introduced a preview of a new feature designed to help AI startups and other businesses address one of the biggest challenges in the space: passing along the underlying costs of AI model usage to their customers.

What makes the new Stripe feature notable is that it goes beyond simply passing token costs. It also allows startups to apply a markup percentage on top of token usage. That means a company could, for example, automatically charge customers 30% more than what the startup itself pays to the model provider for those tokens.

As Stripe explained it, “Say you’re building an AI app: you want a consistent 30% margin over raw LLM token costs across providers. Billing automates the process.”

The billing tool allows a startup to choose which AI models it relies on. It then monitors API pricing for those models, tracks the number of tokens customers use, and automatically applies the selected profit-margin markup.

As previously reported, AI startups are experimenting with a range of pricing models for their services. Many companies offer monthly subscription tiers with usage caps, and once a customer exceeds those limits, additional fees may apply.

Cursor, for example, changed the pricing on some of its plans last year, moving away from unlimited usage and instead introducing rate limits, with added charges for additional consumption.

Without a usage cap, customers can incur very high costs for a startup through heavy model usage, potentially forcing the company to operate at a loss. That issue becomes even more serious for agentic startups. The more customers rely on their agents, the more tokens those agents consume from the underlying model providers, whether that is OpenAI, Google Gemini, Anthropic, or others. That makes pricing decisions and business model design especially important.

Stripe has also launched its own AI gateway, a tool that gives users access to multiple models so they can choose whichever one best fits a given task. According to a post on X by Stripe product manager Miles Matthias, the billing feature also works with widely used third-party gateways, including Vercel and OpenRouter.

Other startups are already offering AI model cost-management tools through their own gateways. OpenRouter, for instance, gives access to more than 300 models and charges a flat 5.5% markup over token costs on its entry-level plan, while also providing budget controls.

Stripe is not currently adding its own markup to the gateway. The new feature remains on the waitlist for now. If Stripe can make it easy for startups to track, bill, and profit from AI usage costs, the feature could prove highly significant. Stripe did not immediately respond to a request for comment about when the feature might become generally available.
