Track Order Source for Fundraising Program

[mpotts20]

I'm setting up a fundraising program with school clubs where I donate a percentage of sales from each product, and I’m looking for the best way to track orders coming in from each group.
My plan is to have each club send people to landing pages (from both printed materials and digital links) where customers can view the fundraising products.
I know I could set up unique promo codes, but I wanted to see other options where the customers wouldn’t have to do anything extra, and i could just track the sales from a specific link or from each landing page. I know there are probably a few ways to do this, so just looking for suggestions. Thanks!

Did this ever get resolved? We are in the process of doing the same for some schools and would love to know if theres a way to track orders coming from a certain group.

Pinging this as I am looking for a similar solution.

This is also something that would possibly work for what I'm looking at.

Anybody have any ideas?
