Create Sage Intacct billing projects from Teamwork.com

**Objective:** Create a project in Intacct from Teamwork project `{project-name}`, with Intacct category `{category}`, linked to the matching Intacct customer. Create it only after the user confirms.

**Step 1: Read the Teamwork project**

Call `teamwork-get-projects` with `name.contains` set to `{project-name}`. If more than one project matches, list them and stop. If none match, say so and stop. Keep `project-name`, `company-name`, `description`, `start-date` and `end-date`.

**Step 2: Make sure Intacct does not already have it**

Call `intacct-get-project` with `project-name.contains` set to the Teamwork `project-name`. If a project with the same or a very similar name exists, show it and stop. Do not create a duplicate.

**Step 3: Find the Intacct customer**

Call `intacct-get-customer` with `customer-name.contains` set to the Teamwork `company-name`. If exactly one customer matches, use its `customer-id`. If several match, list them and ask the user which one. If none match, say so and ask whether to create the project with no customer; do not create a customer.

**Step 4: Confirm**

Show the user exactly what will be created: name, category `{category}`, customer, start date and end date (converted to MM/DD/YYYY, which Intacct requires), and description. Wait for an explicit yes.

**Step 5: Create and confirm**

After the user says yes, call `intacct-create-project` once with `name`, `category`, `customer-id`, `start-date`, `end-date` and `description`. Then call `intacct-get-project` with `project-name` set to the new name and report the new `project-id`.

**Rules & Guidelines:**

* `teamwork-get-projects` is on the teamwork server. `intacct-get-project`, `intacct-get-customer` and `intacct-create-project` are on the intacct server.
* `intacct-create-project` is the only tool that may write, and it may be called once, after confirmation.
* Do NOT call `intacct-create-customer`, `intacct-update-project` or any Teamwork action tool such as `teamwork-update-project`.

**Validation:**

* If `{category}` is blank, ask the user for the Intacct project category before Step 4.
* If the create call fails, report the error as returned and do not retry with changed values unless the user asks.
