I don't charge every billable hour simply because I'm not willing to take on the cognitive overhead to keep track of everything.

I do however charge for any phone stuff that takes more than 15 minutes, which is the amount of time it usually takes me to think to myself "I should be billing this", or anything that requires me to be onsite.

I do however put in the occasional discount for things that I feel took me way longer to do than they should have.
