**Objective:** Build a combined sales and accounts-receivable profile for the BigCommerce customer with email `{email}`, looking at orders from the last `{lookback-days}` days (default 365).

**Step 1: Find the customer in BigCommerce**

Call `bigcommerce-get-customer` (bigcommerce server) with `email` set to `{email}`. If nothing matches, report that the customer is not in BigCommerce and stop. Keep `id`, `name`, `company` and `email`.

**Step 2: Get their orders**

Call `bigcommerce-get-order` (bigcommerce server) with `customer-id` set to the customer id and `date-created.from` set to the start of the lookback window. Total the order count and `total-including-tax`, total `refunded-amount`, and note the latest `date-created` and any `payment-status` that is not paid.

**Step 3: Find the customer in Dynamics GP**

The two systems share no id, so match on name. Call `dynamics-gp-get-rm-customer` (dynamics-gp server) with `customer-name.contains` set to the BigCommerce `company` (or `name` when company is empty). If more than one customer matches, list them (`customer-id`, `customer-name`, `city`, `main-email-address`), prefer the one whose `main-email-address` equals `{email}`, and if still ambiguous stop and ask. If none match, report the customer as present in BigCommerce and absent from Dynamics GP and skip to Step 5. Keep `customer-id`, `customer-balance`, `credit-limit-amount`, `hold`, `inactive` and `payment-terms-id`.

**Step 4: Get open receivables**

Call `dynamics-gp-get-rm-trx` (dynamics-gp server) with `customer-id` set to the GP customer id. Total `document-amount` by `document-type` and list the oldest documents.

**Step 5: Report**

One block per system: BigCommerce (customer, order count, revenue, refunds, last order) and Dynamics GP (customer id, balance, credit limit, hold flag, open documents). Close with flags: customer on hold in GP but still ordering, balance above credit limit, unpaid BigCommerce orders against a GP balance of zero.

**Rules & Guidelines:**

* `bigcommerce-*` tools run on the bigcommerce server and `dynamics-gp-*` tools on the dynamics-gp server. Both servers must be connected.
* Where a GP tool takes `company`, pass `{gp-company}` when it is given; if it is empty, omit `company`.
* This prompt is read-only. Never call any `bigcommerce-*-add`, `-update` or `-delete` tool, and never call any `dynamics-gp-*-add`, `-update` or `-note` tool.

**Validation:**

* If BigCommerce returns no orders in the window, say so and still report the GP side.
* If the GP match was made on name alone, say it was a name match and not an id match.
