How do commissions work? How does the currency change? How does one person run multiple platforms and accounts? How does one person change their time, talk to customers to prevent escalating any communication issue, what does an invoice look like, how does one convey prices as simply as possible and how is time managed to make room for commissions, rates, durations, extra things? What are the terms I should be looking up because I don't know any useful term other than "commission rates"?This is all confusing for me!
