Last week I was asked by one of my Twitter followers;
Any suggestions for an online Project Management Tool? Happy to pay and need to to incude scheduling, milestone / task tracking and have an online document store
The project management scene on Twitter is a vibrant one, just check out some of the latest tweets (messages) from the Project Management on Twitter (#pmot) stream at the moment. When I put that question to the 
community, and as you probably might expect, there were lots of suggestions, recommendations and ideas. Here’s the list and recommendations for you to check out;
Try out DeskAway and let us know what u think? http://deskaway.com/
You can use SharePoint online for your Project Management needs http://office365.com and here’s a video on how you can use SharePoint for Project Management
Check 5pm for an online project management tool www.5pmweb.com
Best PM? For integrated project tracking, communication, collaboration see Traction TeamPage and see Traction TeamPage videos on integrated action tracking and project management http://t.co/jAVPX8i
We use Open Air for scheduling, timesheets control and billing. Sharepoint for document approval and storage http://www.openair.com/Products/PSA-Software-OpenAir
I’d strongly recommend TeamWorkPM for small project teams …despite lack of issue log! For Agile IT projects see JIRA
Internally we use SharePoint, externally we use basecamp from 37Signals. http://basecamphq.com/
Try Teambox too! http://teambox.com/
WORKetc is a powerful integrated solution, doing all you’ve listed above + other things. See this: http://t.co/lccIpCn

GantProject is another one tool,
Twitter: doolphy
Hello!
Can I suggest adding Doolphy to your list?
WORKetc is gaining a lot of steam and it integrates collaborative project management features with additional small business management tools such as CRM, support, and billing.
I think the reason why it’s gaining so much steam is because of how costly and inefficient integrating multiple systems has become. Trying to use 3 separate apps to run a SMB is inefficient and outdated, and WORKetc combats this by putting all SMB needs into one web based system.
