Project Profit

We are considering Zoho Books but have yet to find an easy way to track true Project Profit. We are a consulting firm and need to easily report where we are income to expenses (net profit) on each project. Ideally, the P&L reports would have the ability to customize and filter by project.
What is the status of these additions to your product?
1) Sales Orders "linked" to a project.
2) Invoices created from the Sales Order linked to the project so the revenue is going to the specific project. The ability to invoice from a project only works if you are not using sales orders. *Note: We have not found a report of income by project only (vs. customer).
3) Supplier Purchase Orders "linked" to a project so when we receive the supplier invoice (bill) against the purchase order it is going directly to the project cost.
4) Project Snapshot: ability to capture ALL vs. only the limited time frames provided.
5) Ability to add decimal (.) to hours in project budget for staff hours.

Thank you.
