Find Dynamics GP invoices that are missing from AvaTax

**Objective:** For Dynamics GP customer `{customer-id}`, find sales documents dated from `{from-date}` to `{to-date}` that have no Avalara AvaTax transaction with the same code. If `{to-date}` is empty, use today.

**Step 1: List the GP documents**

Call `dynamics-gp-get-rm-sales-trx` with `customer-id` set to `{customer-id}`, `document-date.from` set to `{from-date}` and `document-date.to` set to `{to-date}`. If nothing comes back, say so and stop. If the result hits the record limit, say it may be truncated and narrow the date range. Keep `sop-number`, `sop-type`, `document-date`, `tax-amount` and `document-amount`.

**Step 2: Look each one up in Avalara AvaTax**

For each GP document, call `avalara-avatax-get-transaction` with `code` set to its `sop-number` and `customer-code` set to `{customer-id}`. Record the match as found, not found, or several, with the AvaTax `status` and `total-tax`. If `customer-code` finds nothing at all, retry once for the first document without `customer-code` before concluding that the customer code differs between systems.

**Step 3: Report**

Give a table of `sop-number`, type, date, GP `tax-amount`, AvaTax `total-tax`, AvaTax `status` and verdict (matched, missing from AvaTax, tax differs, not committed). Put the missing and differing ones first and give counts at the end.
**Rules & Guidelines:**

* Tools whose names start with avalara-avatax- are on the avalara-avatax MCP server; tools whose names start with dynamics-gp- are on the dynamics-gp MCP server. Both servers must be connected.
* This prompt is read-only. Never call any create, update, delete, add, void, commit, adjust, post or other action tool on either server.
* Report what the two systems show. Do not present results as tax advice or as a filed return.

**Validation:**

* Quotes and orders may legitimately have no AvaTax transaction; say that rather than calling them errors, and group them separately from invoices.
* If the customer has no documents in the range, say so and stop.
