Just discovered you

Greeting everybody on this wonderful Sunday.

I just discovered the Zoho suite of products about two hours and I am very impressed. As a small consulting business that is growing I am not sure I have seen ONE place that has this many useful products. I am especially interested in the Projects and CRM components and have already signed up for those.

How is the integration between these products? Is there (or is there plans) a way to use a single sign in for multiple products/modules.

I'd be interested in hearing about other small businesses and what their experience is with this suite of products.
