Compare a 2Checkout customer with Business Central

**Objective:** Compare the 2Checkout customer with email `{email}` against the Business Central customer record and report every difference.

**Step 1: Find the customer in 2Checkout**

Call `2checkout-get-customer` with `email` set to `{email}`. If nothing is returned, call `2checkout-get-lead` with `billing-email` set to `{email}` and report that the person is only a lead. If several customers match, list them with `customer-reference` and stop.

**Step 2: Find the customer in Business Central**

Call `business-central-get-customer` with `email` set to `{email}`. If nothing is returned, also call `business-central-get-customer` with `name.contains` set to the 2Checkout company or last name and list any candidates. If several match, list them and stop.

**Step 3: Compare**

Compare 2Checkout `first-name`, `last-name`, `company`, `address-1`, `city`, `country-code` and `credit-limit` with Business Central `name`, `city`, `state`, `country-code`, `credit-limit` and `blocked`. Treat differences in case, spacing and punctuation as matches.

**Step 4: Report**

Give a table of field, 2Checkout value, Business Central value and Match or Differs. Add one line saying whether the customer is present in both systems, only 2Checkout, or only Business Central, and the Business Central `customer-number` and 2Checkout `customer-reference` side by side.

**Rules & Guidelines:**

* Tools named the 2checkout prefix are on the 2checkout server and tools named the business-central prefix are on the business-central server. Both servers must be connected.
* This is a read-only job. Never call any 2checkout or business-central create, update, add, order or subscription action tool.
* Business Central tools take an optional company parameter; only use it if the user named a company.

**Validation:**

* If either side returns nothing, say which system lacks the customer and still report the other side.
* If the two systems disagree on format (for example US versus United States), report the raw values and note the format difference rather than calling it a data error.
