One of our customers kept entering their Basecamp time into Quickbooks and into a spreadsheet by hand. That was unacceptable. We fixed it for them.

Our solution is SignalTime—a Basecamp data extraction tool allowing exporting of time entries in Quickbooks IIF or as a tab separated file. Also, it has some handy views to show you how all your data is related.

As usual, you must have API access enabled for it to work. Give it a try and let us know what you think: http://genges.com/istore/product/signaltime
