See a customer's full billing picture in one answer

**Objective:** For {customer}, show the full billing picture across Chargebee and PowerGP: subscriptions, invoices and payments from Chargebee next to what PowerGP shows as received and still open.

**Step 1: Resolve the customer**

Call `chargebee-get-customer` (chargebee) with `company.contains` set to the value, or `email` if it contains an at sign. If more than one matches, list them and stop. Note `id`, `company`, `unbilled-charges`.

**Step 2: Chargebee activity**

Call `chargebee-get-subscription` with `customer-id`, then `chargebee-get-invoice` with `customer-id` and `chargebee-get-transaction` with `customer-id`. Summarise active subscriptions with `mrr` and `status`, invoices by `status` with `amount-due`, and payments by `status`.

**Step 3: PowerGP side**

Call `powergp-online-get-customers` (powergp-online-ai) with `customer-name.contains` set to the Chargebee `company`. If none, say the customer is not in PowerGP and skip to the report. If several, list and stop. Then call `powergp-online-get-receivablestransactions` and `powergp-online-get-receivablesapply` with the `customer-number`.

**Step 4: Report**

Sections: Customer match, Chargebee subscriptions, Chargebee invoices and payments, PowerGP receivables, Differences (payments Chargebee marks successful with no applied PowerGP receipt, by amount and date within 7 days).

**Rules & Guidelines:**

* Tools prefixed powergp-online- belong to the powergp-online-ai server; tools prefixed chargebee- belong to the chargebee server. Both servers must be connected.
* Read-only: call only the get tools named above. Never create, change or delete anything in either system.
* Never print card or bank details; report ids, names and amounts only.

**Validation:**

* If one side has no data, report the other and mark the comparison as not possible.
* Note any name-based match as unconfirmed.
