Billing time to clients is something every agency has to deal on a regular basis. I find the process tedious and susceptible to forgetfulness but it has to be done. At Torchbox our minimum billable time is 15 minutes which can fly by if you're flowing on something, or a group of related somethings, which perhaps affect several clients. It can be several hours before you raise your head and realise you haven't billed a single minute, nor can truly account for which of those multiples of 15 can really be attributed to which client. I've written a little bit of software for Torchbox to help monitor this, which I thought deserved a brief blog entry.
