Are reviews play an important role for B2B SEO?

Hey everyone! We are a backpack manufacturer, and we're in the process of relaunching our website. I'm new to SEO. We don't sell individual products; instead, we specialize in prototyping and bulk manufacturing based on customer requirements. From what I understand, reviews and structured data are typically more useful for businesses that sell products individually. Does this approach still work for a business like ours? How can we collect reviews for our website to get higher ranking on Google? Thanks for your advice in advance!
