I've been a software engineer for 4 years and I've recently picked up a side gig doing some contract work for another company.
I've had a few initial introductory and knowledge transfer meetings. I plan to bill for these. Is this appropriate? I'm not physically writing code, but this is required before I am able to, same as any other job.
How can I determine what are appropriate tasks to bill for and what are overhead tasks that are my cost of doing business?
