I am currently working as a technical freelance writer for a client. He has asked me to write 10 lengthy articles (~2000 Words each) about a technical topic in a "tutorial" fashion. We agreed on a fixed rate of $0.2 per word.
Before I started working on the 10 articles, I outlined the articles in a hierarchy of Article-Sections-Subsections-Brief Description in a document. After I was done, the whole outline document was 600 words.
So my question is, should I ask my client for a payment for that outline? (Given that I spent around 3 hours preparing it).
