Selling in B2B is different. It must inform, persuade, and differentiate. I believe that if there is flexibility in the listing price on your website that would help you more than just mere listing the price. If the list price is "firm," it means that the seller is not willing to negotiate. I believe the CTA via enquiry form is a best option as it gives some degree of flexibility.
