Jira Service Desk - Clients should have a reporting feature

Hello Team

Our Company wants to use the JIRA Service Desk for all our clients. So we are talking about 50-500 Clients/Organizations (with 100-10000 employees) each using the customer portal to raise their Support Tickets. We want to give them an efficient Ticket Management system/Portal. So our intention is to let each Client (1-2 Admins) be able to review reports on all their tickets raised with us. We think its too much manual work for us to generate each type of report they require fortnightly/monthly for 500-1000 organizations. It seems like a lot of unnecessary manual work.

We understand JSD Agents only have that permission. We are ready to purchase JSD Agent license for 1-2 people for each organization BUT we want to restrict their access from editing workflows , viewing our internal communication , work logs, etc. Basically we just want them to be able to see issues raised by their own organization and create reports based on them.

Do you think this is possible? My first alternative was to give them JIRA License but they can still see our internal communication and worklogs which is bad We cant seem to attach our server related attachments to the support Ticket , hiding it from the client. I dont think we want to create duplicate tickets in a different project every time and work on those duplicated tickets rather than the original.

Can you please suggest a solution or suitable alternative solutions ?

Thank you for your time and support.
