Trace a Chargebee payment through to Intacct

**Objective:** Trace Chargebee payment or invoice `{chargebee-reference}` into Intacct and say whether the cash was received and applied to the matching invoice.

**Step 1: Find the Chargebee side**

Call `chargebee-get-transaction` (Chargebee server) with `id` set to `{chargebee-reference}`. If nothing returns, call `chargebee-get-invoice` (Chargebee server) with `id` and then `chargebee-get-transaction` with that invoice's `subscription-id` and `customer-id` to find its payments. Record customer id, amount, date, status, gateway and payment method.

**Step 2: Find the Intacct receipt**

Resolve the Intacct customer with `intacct-get-customer` (Intacct server) by `customer-id` `{intacct-customer-id}` if supplied, otherwise by the Chargebee company name. Then call `intacct-get-ar-payment` (Intacct server) with `customer-id`, `receipt-date.from` set 3 days before the Chargebee payment date, `receipt-date.to` 10 days after, and `total-amount.min`/`total-amount.max` both set to the Chargebee amount. If nothing matches, call `intacct-get-deposit` (Intacct server) with a `deposit-date.from`/`deposit-date.to` range over the same window to look for a batched deposit.

**Step 3: Find the invoice it was applied to**

Call `intacct-get-invoice` (Intacct server) with the same `customer-id` and check that its `total-due` is consistent with the payment being applied.

**Step 4: Report**

State one of: received and applied, received but not applied, deposited in a batch, not found in Intacct. Show the Chargebee and Intacct amounts, dates and document numbers side by side, and the gap in days.

**Rules & Guidelines:**

* `chargebee-get-transaction` and `chargebee-get-invoice` are Chargebee tools; `intacct-get-customer`, `intacct-get-ar-payment`, `intacct-get-deposit` and `intacct-get-invoice` are Intacct tools.
* Read-only. Never call `intacct-create-order-entry-document` or any other Intacct create or update tool.

**Validation:**

* A failed or refunded Chargebee transaction is not expected in Intacct; say so instead of reporting a miss.
* If more than one Intacct receipt fits, list all of them and do not pick one.
