Collaborative PM software that can track time across different teams?

As I know there is that functionality in Harvest. But it doesn't equal to Basecamp in other cases.

Maybe that functions are in Confluence.

And definetely you can do that in Comindware Tracker. You should try it on. Maybe it will suit your needs even better than Basecamp does.

Yes, It's possible with Proofhub, a project management software. I am using it for since 2 years and it is surely better than Basecamp. It can do all that basecamp can. You can track time, create to-do's, set milestones, file sharing a lot more.

Infact, Proofhub is the only project management tool to offers real time chat and proofing tool.

I’ve tried several time trackers in the past but stopped with Time Doctor (http://www.timedoctor.com)./ I also used Basecamp for collaboration but its time tracking feature isn’t that much a profit to me.

Time Doctor met all of my needs and was affordable. There are win, mac, and linux versions available so I have never had any issues with computer installations. It takes screenshots every 9min (probably configurable) and allows me to quickly review daily productivity. I get timesheet reports and also the screenshots making weekly payroll a breeze.

If that is the case try Replicon - http://www.replicon.com/

Moreover, they have got integration with top other tools such as Quickbooks, Concur, etc.
