When a user logins, they're directed to the Companies page. In the companies page there is a side panel organizing all the companies into groups, and within each company there are links to the company's contacts, tasks and documents. New companies can be added directly on this page. New groups are added when you necessary in the creation of a company. Within each sub-item(item being contact, task, or documents) of the company are buttons to add new items affiliated to each company. After clicking such buttons, a window will pop-up where information will be entered and then saved. The other links in the navigation bar links to a page that shows all the items that have been entered so far. For example the Tasks link will show all the tasks in a table that is sortable and filterable. Within this link an user can add a new task, and a similar window will show up, with an additional field to link the task with a company. The contacts and documents page will have a similar format. However, for documents it probably isn't necessary to force a link with a company. To make changes to previously entered information, there will be an edit link that appears close to the item . The link shows up after hovering over it with a mouse, or by clicking on the item in some casesin the Contacts field, and in the Company info pages. To edit tasks and documents clicking on them will open a button allowing some information to be changed.
Design notes:
Instead of an extra level in the side panel tree, there could be tabs within the main panel after selecting the company. The windows that appear will be dialogs within the page, not those annoying browser based pop-ups. However, if that is hard to implement, it could be a separate page that redirects to the existing page after the window is saved or canceled.

She then selects tasks, which looks very similar to the empty contacts page with just a button that says +Task. She clicks it an a new window appears.
