Not sure if this is the right place. Hope someone will have an answer.
Someone has asked me to help them set up a basic accounting spreadsheet and help them on a monthly basis to maintain the data. As I'm new to this I'm not sure how much to charge for this work. In case it is relevant, I'm based in North London. I've already spent 1.5 hours working on this. I don't want to overcharge as I don't want to scare away a potential client. On the other hand I also don't want to underestimate the value of my time.
Can anyone help?
