You guys need to have your expectations outlined up front. You shouldn't be hitting them with a bill they don't understand. That is your opportunity to explain (because your the expert they hired) to educate them as to why your hours needed to be more than two on a task.

If you do explain this and you soothe their minds out, they will thank you and respect you even more. If they don't then fire them.

Biggest tip ever you can take away? Stop calling yourself a freelancer. Step up to a tech consultant. People treat freelancers and consultants differently, even if the work is exactly the same. Act accordingly, and use this to your advantage. There is no teacher or boss to tell you must be a freelancer.

Is there some term that lies between freelancer and consultant?

What is there to be afraid of? I don't think anyone should call themselves a "freelancer". It just devalues you. And, when starting your own business: you don't need permission from anyone else to "call yourself something".

Call yourself a "Wordpress Consultant" for example, if you are a WP dev.
