During your intro calls, always discuss with a client directly how you plan to work together.
If you plan to deliver coaching outside of live sessions, such as for resume reviews or essay edits, please make sure your clients are aware prior to purchasing time. Communicate how you'll use time asynchronously in the intro call and provide a written explanation in your conversation with the client or in the details of a package.
You should not log coaching time for time spent upskilling or researching the topics you coach for.
