I'm working on a web application allowing users to plan, organize and book an event for a group of people. Users would like to compare and share different options / packages of the event they are organizing. So we are working on a comparison tool, similar to what you can find in many e-commerce website. But compared to the majority of these comparison tools, users can compare packages of items in our case, which makes ergonomics and understanding much more complicated.
The comparison view isn't the most complicated to design. The most complicated thing is to give the possibility to the user to create a comparison, then to create different packages in this comparison and finally to add items in these different packages.
Do you have any tips, food for thought or know similar products I can benchmark ?
