If it's time for a self-assessment of where your workday time or cash go, 1DayLater can help. If you're a freelancer looking for lightweight client tracking, 1DayLater's also got game. It's a really lightweight, web-based tool for watching where everything goes.
After signing up and signing in, you'll see 1DayLater's basic interface: Value, Project, Date and the optional "Note". If you drove 18km earlier to pick up poster something for a project, simply enter "18km" in Value, "Smith Account" in Project, and "Today" in date, and type in "Poster supplies" in note if you need to. That's it — your data's entered in. If you're about to start working on something right now, there's an on-site timer that automatically plugs your time upon pressing Stop into the Value field.
When you want to get it out, you can export to Office Open XML spreadsheets, which can be opened by most office apps (including Microsoft, OpenOffice and the Apple iWork suite). You can also put together a rather neat-looking graph of your time, money and mileage. More options and tools, including automatic invoices and mileage claims, are coming soon, according to the developers, as 1DayLater is currently an open beta test.
1DayLater is a free service that requires a registration, and would've made a worthy addition to our top 10 tips and tools for freelancers, had we seen it earlier.
