Google Forms helps coaches create forms, share them by link or embed, collect responses, view summaries, and send answers into Google Sheets. That makes it useful for the early admin moments of a coaching business: inquiry forms, discovery call applications, client intake, pre-session check-ins, workshop registrations, post-session feedback, and testimonial requests.
Its main advantage is speed. If you already use Google Workspace or a Gmail account, you can create a usable form in minutes. You do not need to design a new landing page or build a database before you start collecting information.
