Internal Billing is the process of billing and collecting for goods or services transferred from one UMD department or unit to another. In the context of internal billing, one unit acts as a supplier while the other unit acts as a customer.


  • Internal Service Provider – An Internal Service Provider is a UMD department or unit that provides goods or services to another department or unit.
  • Internal Service DeliveryInternal Service Delivery is Workday’s term for “internal billing.” It is the financial transaction resulting from the Internal Service Provider billing and collecting for goods or services sold to another UMD department or unit. Only Internal Service Providers (not the receiver of goods or services) can initiate the internal service delivery process.
  • Internal Catalog – Internal Catalogs are lists of goods/services and their descriptions, unit costs, spend categories, and lead times. Internal catalogs are created by the department’s Internal Catalog Data Entry Specialist and must be approved by the Controller’s Office. An internal catalog is specific to one Internal Service Provider. One Internal Service Provider, however, may have multiple catalogs.
