Compare a Dynamics GP invoice with its AvaTax transaction

**Objective:** Compare Dynamics GP sales document `{sop-number}` with the Avalara AvaTax transaction that has the same code and report any difference in tax, total or lines. If `{sop-type}` is given, use it to pick the right GP document; default to showing every type that matches.

**Step 1: Read the document in Dynamics GP**

Call `dynamics-gp-get-rm-sales-trx` with `sop-number` set to `{sop-number}` (and `sop-type` set to `{sop-type}` if it is not empty). If more than one document comes back, list them and stop. If none, say so and stop. Keep `customer-id`, `document-date`, `subtotal`, `tax-amount` and `document-amount`. Then call `dynamics-gp-get-rm-sales-line-item` with the same `sop-number` and keep each `item-number`, `quantity` and `extended-price`.

**Step 2: Find the transaction in Avalara AvaTax**

Call `avalara-avatax-get-transaction` with `code` set to the GP `sop-number` and `customer-code` set to the GP `customer-id`. If nothing comes back, report the document as present in Dynamics GP and not recorded in AvaTax, and stop. If more than one comes back, list them with `document-type` and `status` and stop. Keep `id`, `status`, `total-amount`, `total-tax` and `total-exempt`. Then call `avalara-avatax-get-transaction-line` with `transaction-id` set to that `id` and keep each `item-code`, `quantity`, `line-amount` and `tax`.

**Step 3: Compare**

Compare GP `tax-amount` against AvaTax `total-tax` and GP `subtotal` against AvaTax `total-amount`. Match lines by `item-number` against `item-code`; for each pair compare `extended-price` against `line-amount` and `quantity` against `quantity`. List lines present on only one side. Treat rounding differences under 0.01 as a match.

**Step 4: Report**

Give the header comparison, a line table with a verdict per line, and the AvaTax `status` (a Saved or Temporary transaction is not yet committed). Finish with a one-line conclusion.
**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:**

* If either system returns nothing, say which and stop.
* If the two systems disagree, show both amounts and the difference; do not suggest which is correct.
