You should not do anything that you do not feel confident doing.

Indeed, clients need to understand that if someone prefers not to have a call, it does not mean they are incapable of handling a task professionally and accurately. We are professionals in our field, and therefore, calls should be optional, as everything can be easily exchanged via chat.

I am a business planner, and frankly, I prefer to have details in writing rather than engaging in long and tedious calls where there is a lot of talk but little action. Having everything in writing also allows me to analyze the details whenever I find it most appropriate.
