What do you like best?
I work with 10-15 clients at a time, and Clockk automatically tracks and assigns tasks to each client. I benchmarked Clockk against my existing workflow, and it finds me around an hour a day of billable time I forgot or underestimated.
What do you dislike?
Given its low price point, there's not much I dislike. It's simple and does what I need.
That said, I would be interested in an integration with Xero so I could automatically generate an invoice at the end of each month. Right now I just pull the totals and make my own invoice, which takes all of 2 minutes per client.
What problems are you solving with the product? What benefits have you realized?
Time tracking has always sucked. You have to consistently stay on top of it during your day before you lose track and have to make it up at the end of the day.
With Clockk, you work your day normally without even thinking of time tracking. At the end of each day, you get a visual review of everything you did, and Clockk auto assigns most tasks to clients. If a task isn't assigned yet, (or assigned wrong), it provides you enough info about that task to easily assign it to the correct client. Nothing is ever missed or lost, so I never have to guess on timesheet entries.
I spend 3 minutes a day on Clockk, and it finds me thousands a month in unbilled or underbilled time. It also gives me a history of each day, so if a client ever questioned my billing, I can pull it up a day in the past and defend my #'s with confidence.
Seems like a total no brainer if you like accurate billing and making more money.
