We are attempting to generate barcodes for the quote PDF when the quote is being generated in CPQ. It will appear in it's own column for the corresponding line-item. 

I've been exploring ways to implement this with apps in AppExchange. I'd appreciate any recommendations from those who have had to create a PDF with barcodes generated for each line item. Which application are you using?

What is the trigger for the application to fire when a quote document is generated?

Thanks!
