If you want to hang a banner, it means it. What audit companies fear most is that your standards are too poor. As a customer, he wants to give you a certificate, but he is afraid of smashing his own brand. So as long as you do a little better, find the correct answer to the question of understanding the system, take the auditor to the place you want him to know, and avoid the place you don't want him to know.
Everything will be fine.
