You need to write a questionnaire in the form of a Google Form.
Use a combination of :-
closed questions - multiple choice questions
open questions - text or paragraph questions.
Try to use a combination of both types so you get a good range of information.

You can either send this questionnaire to your customers before you talk to them so they can see the questions and be prepared, or you can ask them the questions verbally and fill in the answers yourself while you are talking to them.
