Don't get stuck with an inflexible task-centric system that forces you to tie your time entry to one task from a defined set. Tempo uses tags - they're infinitely flexible and provide all the granularity you need.

With Tempo you don't have to be at a computer to track your time. Send short Text messages through Twitter or to your @keeptempo address. Point your phone's browser to m.keeptempo.com for mobile web time entry. Or use your @keeptempo.com address from desktop email too.

Tempo sports a flexible time log interface so you won't find any hard-coded or canned reports you can't use. Choose any projects, people, tags, and date range - the time log will adapt to meet those criteria.

Instantly chart any report to visualize trends, resource utilization, and projects.

View all your project estimates in one place. Tempo's project dashboard gives you a high level red/yellow/green view of your project burn versus estimates.

Tracking time is great but at the end of the month you need to get paid. Tempo isn't an accounting system but we do make it really easy to prepare invoices for your time with two of the best: Blinksale and QuickBooks.

Project setup only takes seconds with Basecamp support. Choose your projects and Tempo will import them and automatically send invitations to your team. Keep time with Tempo, manage your projects with Basecamp!

Every Tempo user has an individual account so they own their time. You can invite anyone to join your project team (even folks on free plans). Time is shared between team members so that everyone can use the same information for billing, estimation, and tracking. Never double enter time again!

As a principal or project manager it can be difficult to stay on top of project billing. Not so with Tempo - all time entries in the system are available as RSS feeds.

Tempo makes it simple to export your data as a PDF file or CSV spreadsheet.
