Data shows that over 80% of B2B buyers use mobile devices at work, and more than 60% say mobile played an important role in their most recent purchasing decision. This means your product information, inquiry entry points, and order confirmation processes need to work smoothly on mobile devices—not just be "accessible." In practice, you need to prioritize checking a few things: whether your website has responsive design, whether load times are reasonable on 4G connections, and whether filling out an inquiry or confirming an order requires screen zooming to operate. If customers abandon the process halfway through because the interface isn't mobile-friendly, you'll likely lose that deal. Mobile optimization is no longer a bonus—it's a baseline requirement in B2B e-commerce.
