Manage Stripe Customers & Subscriptions with AI Assistant

Windsor’s Stripe connector can create customers and start subscriptions, not just report on revenue. Once connected, ChatGPT, Claude, or Copilot can create a new customer and put them on a recurring subscription, straight from a chat, with the exact amount and terms shown to you before anything is created.

What you can do

• Create a customer. An email, a name, or both; an optional description and metadata.
• Create a subscription. Billing a fixed amount on a recurring interval for an existing customer, created inline as a new price unless you point it at an existing product.

The two chain together: create the customer first, then pass the customer id it returns into the subscription action.

Prompts worth running

Create a Stripe customer for [email protected], then start a $49/month
subscription for them.

Set up a customer for this new client and bill them $1,200 a year,
due on receipt.

Create a customer named "Acme Corp" with a quarterly subscription at
$2,500, invoiced rather than auto-charged.

Three details worth getting right before you ask for this

Amount is in the currency’s smallest unit. For a currency like USD or EUR, that means cents: 5000 means $50.00, not $50. This is the single most common integration mistake with Stripe’s own API industry-wide, so it’s worth having your assistant read the amount back to you before it creates the subscription, not after.

The default is an emailed invoice, not an automatic charge. Unless you specify charge_automatically, a new subscription defaults to send_invoice, which emails the customer an invoice rather than charging a card on file, and gives them until the due date (0 days, due on receipt, unless you set days_until_due) to pay. If the goal is to charge a saved payment method immediately, that has to be asked for explicitly.

A subscription needs a customer to already exist. There’s no single action that creates a customer and a subscription in one step; the customer id from the first action is a required input to the second. If you’re setting up a new client, expect two actions run back to back, not one.

You’re always in control

Your assistant shows you the exact customer details, amount, currency, and billing terms before anything is created. Nothing runs without your confirmation, and the list of actions available to it is pulled live from Windsor’s API, so it always reflects what your connected Stripe account can currently do.
