Creating pages for clients to view account history, notes, etc.

Hi,

I own a small technology consulting firm, and use wordpress for very basic sites for clients that request one. I’ve been able to accomplish most of what they (and I) need by googling and experimenting up until this point.

I’d like to give each client an account to log into my wordpress site, and view their payment histories, notes about past work I’ve done for them, details of the tech they own, etc..

Is there a plugin that can assist with this kind of thing, or is this something that just needs to be done page-by-page manually?

Thanks in advance!
