Fellow designers, what kind of tool do you use for client information intake or requests?

Hello guys and gals. I’m curious on this topic cause asking in my immediate circle I’ve gather information ranging from using Google Docs in a spreadsheet and asking the client to put his information in the corresponding cell to using a more elaborate process in a mix between Microsoft Forms connected to Microsoft Teams and Planner. Is there a tool you particularly use for client intake and requests? I’ll love to read from you, thanks!
