-**CRITICAL:** Always use `mode="delete"` and reverse order.
+**CRITICAL:** Always use `mode="delete"`. Site Impex `services.xsd` requires this sequence: `service-credential`, then `service-profile`, then `service`. Use the **same element order for install and uninstall**. The platform processes elements in document order; putting `<service>` first makes the uninstall file invalid against the XSD, so services are not deleted. Impex is safe deleting credentials and profiles first because ORM nulls `SERVICE.CREDENTIALID` / `PROFILEID` when those objects are removed.
+
+**BM UI vs Site Impex:** Business Manager UI still requires deleting the service first (`RemoveServiceProfile` / `RemoveServiceCredential` refuse delete while a service references them). That UI rule does **not** apply to CAP uninstall IMPEX.
