See the real margin on a client from Rillet and Teamwork.com

**Objective:** Estimate the margin on `{company-name}` between `{from-date}` and `{to-date}` (default today) by setting Rillet revenue against Teamwork delivery cost.

**Step 1: Find the client and its projects in Teamwork**

Call `teamwork-get-companies` with `name.contains` = `{company-name}`. If several match, list them and stop. Call `teamwork-get-projects` with that `company-id`.

**Step 2: Read delivery cost and effort**

For each project, call `teamwork-get-time` with `project-id`, `time-logged.from` = `{from-date}` and `time-logged.to` = `{to-date}`, with no billable filter. Total hours, `cost-total`, `billable-total`, and the billable share of hours. Note entries where `cost-total` is zero; the person has no cost rate.

**Step 3: Read revenue in Rillet**

Match the Teamwork company to a Rillet customer. Call `rillet-get-customers` (it takes no filters and returns every customer) and compare its `name` and `invoicing-name` to the Teamwork company `name`, ignoring case, punctuation and legal suffixes such as Inc, LLC, Ltd, Corp and GmbH. If no name matches, call `teamwork-get-people` with the Teamwork `company-id` and compare each contact's `email` with `email` from `rillet-get-customer-emails`; the same address, or the same company email domain (never a public domain such as gmail.com or outlook.com), is a match. State which rule produced the match. Call `rillet-get-invoice-lines` and total `line-total` for that `customer-id` whose revenue period overlaps the review period (use `invoice-date` if there is no period). Subtract matching lines from `rillet-get-credit-memo-lines` with the same `customer-id` and date range.

**Step 4: Report**

Per project: hours, cost, billable value. Then the client total: revenue (Rillet), cost (Teamwork), margin and margin percent, effective revenue per hour (revenue / total hours), and billable value not yet invoiced (Teamwork billable total minus Rillet revenue, if positive). List any people with hours but no cost rate, and say the margin is overstated by their time.

**Rules & Guidelines:**

* Tools starting teamwork- are on the teamwork MCP server; tools starting rillet- are on the rillet MCP server. If a tool from either server is unavailable, say which server is not connected and stop.
* This prompt is read-only. Do NOT call `rillet-add-invoice`, `rillet-update-invoice`, `rillet-add-customer`, `rillet-update-customer`, `rillet-add-credit-memo`, `teamwork-create-company`, `teamwork-update-company`, `teamwork-create-time-entry`, `teamwork-update-time-entry`, or any other tool on either server whose name starts with add, update, create, apply, set or record.
* Never convert between currencies. If Teamwork and Rillet amounts are in different currencies, report both side by side and say the comparison is not like for like. Teamwork's site currency is `currency-code` from `teamwork-get-account`.
* Revenue is invoiced revenue, not recognised revenue. Say so.

**Validation:**

* If no customer matches in Rillet, report the cost side only and say revenue could not be found.
* If no time is logged, report revenue only and say there is no delivery cost to compare.
