There is no such product available. Case closed! (Although there is a product to color the water in your pool for a short period of time, although, alas, it is merely for decor.)

Billing targets can vary, but some firms have established goals for associates to clock about 1,500 to 1,600 hours a year, while certain New York firms have set the bar much higher for associates at between 2,000 and 2,200 hours.
Example: Let's say your firm's current billing efficiency is at 65% (24 hours out of a 40 hour work week). Capturing and billing an additional 20 minutes/day equals an increase in billable efficiency of only 1.25% - the effect on the bottom line however is an increase of over $12,000/year per employee!
