For a COM component to work with the pipeline it MUST
implement all or some of these interfaces

IPipelineComponent (mandatory)
IPipelineComponentAdmin (mandatory)
IPipelineComponentDescription (mandatory)
ISpecifyPieplineComponentUI (optional if you're using
custom properties)
and a few more like IPersistDictionary etc

Check the help file for Commerce Server on Custom Pipeline
Components and you find all this information, code samples
and such.

Have fun !
