Stripe Billing Operations

Execute billing and payment operations on Stripe: customers, products, invoices, payment links, subscriptions, refunds, and disputes.

MCP is optional. This skill works with MCP (auto), Stripe CLI, or Dashboard. See BACKENDS.md for execution options.

Three Hard Rules

1. Read before write — Before creating customer/product/price, check if it already exists to avoid duplicates
2. Money operations require confirmation — Refunds, subscription changes, dispute updates must be confirmed before execution
3. When in doubt, search — If unsure about object ID or parameters, search first, don't guess

Security Rules

Dangerous Actions (Require Confirmation)

Before executing these operations:

1. Display — Show object ID and key fields
2. Explain impact — Amount, timing, consequences
3. Await confirmation — Wait for explicit "confirm"/"yes"/"proceed"
4. Execute and receipt — Return result + object ID + status

Example confirmation prompt:

About to execute refund:
- PaymentIntent: pi_xxx
- Amount: $50.00 (full amount)
- Reason: requested_by_customer

Reply "confirm" to proceed, or "cancel" to abort.

Common Workflows

Create Customer

1. Search/list to check if customer exists (by email)
2. If not exists, create_customer(name, email, metadata)
3. Return cus_xxx + key info

Create Product and Price

1. List products to check if already exists
2. create_product(name, description)
3. create_price(product=prod_xxx, unit_amount=cents, currency)
4. Return prod_xxx + price_xxx

Create and Send Invoice

1. Confirm customer ID (list_customers if unknown)
2. create_invoice(customer=cus_xxx, collection_method, days_until_due)
3. create_invoice_item(invoice=inv_xxx, price=price_xxx, quantity)
4. finalize_invoice(invoice=inv_xxx)
5. Return inv_xxx + hosted_invoice_url

Create Payment Link

1. Confirm price ID (list_prices if unknown)
2. create_payment_link(line_items=[{price, quantity}])
3. Return payment link URL

Refund (Dangerous)

1. list_payment_intents to find target payment
2. Display pi_xxx + amount + customer info
3. Request user confirmation
4. create_refund(payment_intent=pi_xxx, amount?, reason)
5. Return re_xxx + status

Cancel Subscription (Dangerous)

1. list_subscriptions(customer=cus_xxx) to find target
2. Display sub_xxx + status + next billing date
3. Ask: cancel immediately or at period end?
4. After confirmation, cancel_subscription(subscription=sub_xxx)
5. Return cancellation result

Default Configuration

• Currency: Use user-specified; else use existing object's currency; else ask
• Amount: Accept decimals, auto-convert to smallest unit (e.g., $19.99 → 1999)
• Output: Object type + ID + key fields + next steps

Limitations

These operations are NOT available via standard tools:

• ❌ Create PaymentIntent / charge directly
• ❌ Create subscription (only list/update/cancel)
• ❌ Create Promotion Code (only coupon)
• ❌ Delete objects

For these, use Dashboard or API directly.

File-based Pipeline

When integrating into multi-step workflows:

runs/<workflow>/active/<run_id>/
├── proposal.md                # Requirements / objective
├── context.json               # Known IDs (customer, invoice, etc.)
├── tasks.md                   # Checklist + approval gate
├── evidence/stripe-actions.md # Operations to execute (money ops written here first)
├── evidence/receipt.md        # Results + object IDs
└── logs/events.jsonl          # Optional tool call summary (no sensitive data)
