Post a WooCommerce order to the right Sage Intacct account

**Objective:** Record WooCommerce order `{order-number}` in Intacct as a `{transaction-type}` document (default Sales Invoice) for Intacct customer `{intacct-customer-id}` (default: found from the order), after confirming it has not been posted already. Write nothing without the user's confirmation.

**Step 1: Read the WooCommerce order**

Call `woocommerce-get-order` with `order-number` = `{order-number}`; if nothing matches and the value is numeric, retry with `order-id`. If it matches more than one order, list them and stop. If the order `status` is pending, failed, cancelled or refunded, report that and stop. Keep `order-id`, `order-number`, `created-date`, `status`, `customer-id`, `customer-email`, `billing-first-name`, `billing-last-name`, `total`, `shipping-total`, `discount-total` and `currency`.

Call `woocommerce-get-order-line` with `order-id` and keep each line's `line-sku`, `line-name`, `line-quantity` and `line-price`.

**Step 2: Check it is not already in Intacct**

Call `intacct-get-invoice` and `intacct-get-order-entry-document` with date ranges covering the order date to 30 days after it. If any document's `reference-number` or `customer-po-number` equals the order number (ignoring a leading `#`), report that document and stop.

**Step 3: Find the Intacct customer**

If `{intacct-customer-id}` is set, call `intacct-get-customer` with `customer-id` = it and use it. Otherwise, if the order has a non-zero `customer-id`, call `woocommerce-get-customer` with it to get the `billing-company`. Then match on the order's `customer-email`:

Try, in order, and stop at the first single match:

1. `intacct-get-contact` with `email` = the WooCommerce email, then `intacct-get-customer` with `customer-name` = the contact's `company-name`.
2. If the WooCommerce customer has a `billing-company` (from `woocommerce-get-customer`), `intacct-get-customer` with `customer-name` = that company.
3. `intacct-get-customer` with `customer-name` = the WooCommerce first and last name.

Treat a match as confirmed when the Intacct customer's `email` equals the WooCommerce email (ignoring case) or is empty. If it holds a different email, report it as a possible wrong match instead of using it.

If nothing matches, or a step matches several customers, list what you found and ask the user for the Intacct customer-id. Never create a customer from this prompt; suggest the sync-customer-to-intacct prompt instead.

**Step 4: Match the items**

For each order line, call `intacct-get-item` with `item-id` = the `line-sku`; if nothing comes back, retry with `upc` = the `line-sku`. Every line must resolve to exactly one Intacct item. If a line has no SKU or no matching item, list it and stop.

`intacct-create-order-entry-document` accepts at most two lines. If the order has more than two lines, report that it cannot be posted by this tool and stop. Do not merge or drop lines.

**Step 5: Confirm, then post**

Show the user: customer id and name, transaction type (`{transaction-type}`, default Sales Invoice), date (the order's created date), reference number (the order number), each line's item-id, quantity and unit price, and the document total against the WooCommerce total. Say plainly that WooCommerce tax, shipping and discounts are not carried across by this tool, so the totals may differ by those amounts.

Only after a yes, call `intacct-create-order-entry-document` once with `customer-id`, `transaction-type`, `date`, `reference-number` = the order number, `customer-po-number` = the order number, `item-id`, `quantity`, `price` and, for a second line, `item-id-2`, `quantity-2` and `price-2`. Leave `state` unset so Intacct applies its default.

**Step 6: Confirm**

Report the returned `document-id`, then call `intacct-get-order-entry-document` with `document-id` and show its total and state.

Then offer to record the posting on the WooCommerce order. Only after a second yes, call `woocommerce-add-order-note` once with `order-id`, `note` = "Posted to Intacct as " followed by the transaction type and document-id, and `customer-note` = false.

**Rules & Guidelines:**

* `woocommerce-get-order`, `woocommerce-get-order-line`, `woocommerce-get-customer` and `woocommerce-add-order-note` are on the woocommerce server. `intacct-get-invoice`, `intacct-get-order-entry-document`, `intacct-get-customer`, `intacct-get-contact`, `intacct-get-item` and `intacct-create-order-entry-document` are on the intacct server.
* The only write tools this prompt may call are `intacct-create-order-entry-document`, once, after confirmation, and `woocommerce-add-order-note`, once, after a second confirmation, always as a private note. Do NOT call `intacct-create-customer`, `intacct-update-order-entry-document`, `woocommerce-update-order` or any other write tool.
* If the user does not know the transaction type, read recent documents with `intacct-get-order-entry-document` and offer the `transaction-type` values in use.

**Validation:**

* If the order currency differs from the customer's Intacct currency, stop and ask the user how to proceed.
* If the create call fails, show the error, do not retry with changed values, and stop. Do not add the WooCommerce note.
