Hey, @HB2023
Happy to help! When you say you want the app broken down on the backend? Are you referring to say the individual inventory of each item that make up the bundle?
For example if you sell a bundle pack of shirts (say 10 different colors), when one of those packs are purchased, that 10 of the individual shirt color inventory goes down one each?
If there is anything else I can help you with, please let me know.
