Multi-User CRM Design

Hey peoples,

I'm working on a CRM-like solution for my company. Things are progressing well at the moment, but we have an opportunity to share this CRM with other like-companies in our industry. We would likely do a subscriber type setup.

Right now I'm planning on having each "user/company" access a centralized system/application folder, that way when I update any pieces of the application all the subscribers will see it. The issue I'm running into when I think about it is how would I handle a subscriber that might want some more custom tweaks? Is it better for each "user/company" to have their own application folder so I can customize? This seems like it could get messy quick.

Thanks in advance!

James
