Cloud apps for project management, accounting & job costing?

A recent query from Naomi2000 addressed the need for software with integrted project management and accounting functions (particularly job costing). I felt it necessary to mention the capabilities of a few on-premise applications, but since the prospective user is an IT consultancy, I felt it would be remiss not to suggest potential Cloud solutions.

I know that the IRIS PROJECTminder Cloud application goes part of the way towards addressing the solution (it only outputs data to GL systems rather than handling the accounting itself).

What other Cloud applications are there that might fit the bill. Feel free to discuss their capabilities here, but it would also help to copy suggestions back into the Any Answers thread.
