Internal Service Provider & External Service provider - There is no difference in functionality or feature between them. These are just 2 different license models for the Maximo Service Provider add-on.
Internal Service Provider would be for customers that are managing services for their own organization. For example maybe Client has IT or Facility services departments which provide services to other departments like Sales within their organization.
In this case IT department internally charges sales for IT services using a chargeback. If this is how you want to use Maximo for Service Provider then you would purchase an Internal license.
External Service Provider would be for customers that manage assets and services for other 3rd parties outside of their organization.
For example CompanyA providing IT services to Client and other third parties. In this case, CompanyA is the Service Provider which uses Maximo for Service Provider to deliver services to client.
These customers pay CompanyA for those services. If this is how you want to use Maximo for Service Provider then you would purchase an External license.
