I wanted help with group storage. I have a group of 10 with individual accounts but we need a way to have more storage and be able to sync with each other etc. Is there a group thing or do we just need to individually pay for storage upgrade annually?
Only one has to buy the extra storage, make a group Library and invite the other members. The other members "share" the storage through the group library.
If you only need storage for one group library, only the owner needs to purchase an individual storage subscription. All storage for items in a group library counts against the owner's storage quota.

If you want to buy storage for multiple users at once, a Zotero Lab plan might be appropriate https://www.zotero.org/storage/institutions
