Have anybody created a script for delivery notes/coli's? that can generate PDF's or similiar. Or is there a known add-on to NS that is suitable for creating delivery notes automatically?

N/render Module is the usual for pdf generation

Ye thanks, i am aware of the pdf generation, but if there already exists a pdf generation for shipping notes that would be nice

as in a packing slip?

Yes

thats the keyphrase you want to search the help for
