With a workforce of 12 full time programmers all working on different projects the amount of hours i wasn't billing for was astonishing, along with missed expenses, the amount i was "losing" each month was probably in the thousands.
After using Clockbase for 2 months, my revenue is up, productivity is up, projects are getting completed much quicker and i get a true representation of what each developer is actually doing.
I would recommend Clockbase to everyone that has staff to manager. Its easy to use, browser based, has a great app, i can auto invoice clients, turn worked hours and expenses into invoices (where before i was just using excel).
There is a free month trial so give it a go now - www.clockbase.co.uk
