Just getting set up for the first time. 

We have a business partner that wants access to their pipeline. We have 3 x pipelines and only want to give them access to one. How do I do this - under Teams? 

We are on the lowest plan so assume we have to upgrade. Do external users also have to pay the upgraded sub price? 

PS - I don't want to have to add them to each opportunity as a follower - too high maintenance
