Match a Chargebee customer to the right Intacct customer

**Objective:** Find the Intacct customer record that corresponds to Chargebee customer `{chargebee-customer}` (a Chargebee customer id, email or company name) and report how well the two match.

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

Call `chargebee-get-customer` (Chargebee server). If `{chargebee-customer}` contains "@" filter by `email`; if it looks like an id filter by `id`; otherwise filter by `company.contains`. If more than one customer matches, list them (id, name, company, email) and stop.

**Step 2: Find the customer in Intacct**

Call `intacct-get-customer` (Intacct server) with `customer-name.contains` set to the Chargebee company name (or the person's full name when there is no company). If `{intacct-customer-id}` was supplied, call it with `customer-id` instead. Also call `intacct-get-contact` (Intacct server) with `email` set to the Chargebee email to see whether a contact carries that address. If Intacct returns several customers, rank them by how closely name, city and state agree with Chargebee and show the top 3.

**Step 3: Report**

Show the two records side by side: name, company, email, billing city/state/country, status, and the open balance on each side (Chargebee unbilled charges, Intacct total due). Give a verdict: exact match, probable match (name the differences), or no match in Intacct.

**Rules & Guidelines:**

* `chargebee-get-customer` is on the Chargebee server; `intacct-get-customer` and `intacct-get-contact` are on the Intacct server.
* Read-only. Never call `intacct-create-customer`, `intacct-update-customer`, `intacct-create-contact` or `intacct-update-contact`.
* Never state that two records are the same customer on a name match alone when the email or address disagrees; call it probable.

**Validation:**

* If Chargebee returns nothing, say so and stop.
* If Intacct returns nothing, report the customer as present in Chargebee and absent from Intacct, and suggest checking spelling variants such as "Inc" or "LLC".
