how should I set up to track additional oders after 1st sale is won?
Create a separate pipeline to put the deals after the 1st sale
You just create new deals for additional orders. What do you mean by tracking Separate from first one? if You want to distinguish between an initial sale and additional ongoing my recommendation would be a deal details field rather than a separate pipeline.
Thank you for the feedback, I am new to Pipedrive but really like it so far!
