I'm interested to use Zoho CRM + Project + Invoice, but I'm the following questions:

Do they share data? For example, I create a new account in CRM, then I win the project. 

- Do it pass to Zoho Project?

- Can I invoice the project from Zoho Invoice?

- Can I share contacts between CRM, Project and Invoice.

- Can I sync calendar with Google Calendar?

- The account that I created in CRM, Is it available from Invoice? or should I create it again?

Thanks you very much.
