Here are some terms which will be used throughout the ELMA manuals.

A company that connects organizations to the Peppol network. A service provider is associated with one or more domains, and participants registered by the provider will only be approved for message exchange within the provider’s domain(s).
Access point (AP)
Represents a physical access point service endpoint, accessible through one or several URLs.
An access point has one or more physical endpoints represented by a URL and transport profile.
Transport profile
The transport method that must be used for communicating with a given AP. AS4 is an example of a transport profile.
Access point provider (APP)
An access point provider operates APs that the SPs can use by making an agreement.
An agreement between an SP and an APP for usage of a specific access point.
Standardized, maintained collections of document types used in e-procurement.
Organizations that are connected to the Peppol network. (An organization might act as its own SP.) You can think of this as a “contract” between an organization and an SP, that connects the SP’s customer organizations to the Peppol network by means of the SP’s associated APP’s AP.
