Client-centered

I decided to start CAPLS office (Gyouseisyoshi Office) on 3rd November. Since this is my second business, I would like to plan and prepare better than the other business.
I am considering the three basic concepts: Advanced, Affordable and Agile.
-I will use advanced tools to work effectively.
-I set affordable fees for clients.
-I will work agilely to have clients’peace of mind.
Anyway, client-centered thinking is important.
Referring to others’ practices, I would like to add my own ideas to fulfill these three concepts.
