I was wondering if I could use your forms to build a member portal site/technology that I could add to my site, to enable clients to log in and access their billing data. In short, I want to be able to make specific files available to specific accounts. Example "Client A" logs in and sees "Invoice A1, A2 and A3." The "Client B" logs in and sees "Invoice B1, B2 and B3." So I can upload specific files to specific accounts. Can your technology accommodate this?
