I work as web consultant (freelancer). I work basically from home at an hourly rate. In my contract which was mostly through email, I am supposed to charge in increment of 30min. If something takes less than in 10 min. to fix, a charge for 30min will apply. If something gets fixed in 40min, charges of 1 hour will apply.
My question is about email support. I often get email from clients asking about various questions and the work that I do. These are not tasks for me but something like, this is not working, the page is broke, it does not work on my pc etc etc. My question is, is technical support chargeable as freelancer?
One might suggest to just add up these hours. However it does not take that long to answer these email, something around 1min to 10min, but it does interrupt my regular work.
