See a customer's billing in Stripe and Business Central at once

**Objective:** Build a billing overview of the customer `{customer}` (a Business Central customer number, an email address or a name) from Business Central company `{company}` (default: the default company) and from Stripe.

**Step 1: Find the customer in Business Central**

Call `business-central-get-customer` with `company` set to `{company}`. If `{customer}` contains `@`, filter by `email`. Otherwise try `customer-number` first, then `name.contains`. If more than one customer matches, list them and stop, asking the user which one they mean.

**Step 2: Open receivables in Business Central**

Call `business-central-get-posted-sales-invoice` with `sell-to-customer-number` set to the customer's number and `remaining-amount.min` set to 0.01. Note which are past their `due-date`.

**Step 3: Find the same customer in Stripe**

Call `stripe-get-customer` with `email` set to the Business Central customer's email. If the email is empty or finds nothing, try `name` with the Business Central name. If Stripe still finds nothing, report the Stripe sections as "not found in Stripe" and go straight to Step 5.

**Step 4: Stripe billing detail**

With the Stripe `customer-id`:

* `stripe-get-subscription` for its subscriptions (status, current-period-end, cancel-at-period-end).
* `stripe-get-invoice` with `status` set to open, for unpaid Stripe invoices.
* `stripe-get-charge` with `status` set to failed, for failed payments.
* `stripe-get-payment-method` for saved cards; flag any card whose expiry is within 60 days of today or already past.
* `stripe-get-upcoming-invoice` for the next amount Stripe will bill.

**Step 5: Report**

A short header (Business Central customer number and name, Stripe customer-id, email), then:

1. Business Central: balance-due, credit-limit, blocked, and a table of open invoices (invoice-number, due-date, remaining-amount, overdue yes/no).
2. Stripe: delinquent flag, subscriptions, open invoices, failed charges in the list returned, cards and their expiry, next invoice amount and date.
3. Attention: a bullet list of anything that needs action, such as an overdue Business Central invoice, a delinquent Stripe customer, an expired card or a subscription set to cancel.

**Rules & Guidelines:**

* Tools whose names start with business-central are on the business-central server; tools whose names start with stripe are on the stripe server.
* This prompt is read-only. Do NOT call any Business Central create or update tool, including `business-central-update-customer`.
* Stripe amounts are in major currency units, the same as Business Central. Show each amount with its currency.

**Validation:**

* If the customer is not in Business Central at all, try Stripe directly with `{customer}` as an email or name, report what Stripe holds, and say it has no Business Central record.
* If the Business Central and Stripe names differ for the same email, show both names in the header.
