A recent Forrester study provides eye-opening numbers: 44 percent of B2B buyers are willing to switch suppliers – not because of the product, not because of the price, but because the digital buying experience does not meet their expectations. In 2025, a mid-sized machinery supplier from the Rhineland lost three long-standing major customers to a competitor. The reason: the customers wanted to order online, check availability, and view their order history – functions the supplier could not offer. Cases like this are no longer isolated. They show that the balance of power in B2B has shifted: today, B2B buyers expect digital standards that were common only in B2C just a few years ago.
Why the digital buying experience is becoming a critical competitive factor
B2B purchasing has changed fundamentally. Buyers who order from Amazon in seconds and track delivery times in their private lives will not accept clunky ordering processes at work. They expect self-service, transparency, and speed – whether they are ordering screws, chemicals, or machines. This trend affects mid-sized manufacturers and wholesalers in particular, who have traditionally relied on personal customer relationships and field sales.
The Forrester study shows that companies that neglect their digital sales channels do not just lose new customers. They also put existing customers at risk. While you are still debating whether an investment in B2B e-commerce in 2026 is worthwhile, your competitor has already built a working online shop with customer accounts and real-time availability. Today, supplier changes happen more quietly and more quickly than before – often without any warning, simply because another provider makes the buying process more convenient.
For managing directors and sales leaders, this means the digital buying experience is no longer a nice-to-have. It is a hard competitive factor. If you do not deliver here, you risk measurable revenue loss.
Six concrete expectations B2B buyers will have in 2026
The requirements of B2B buyers are clearly defined. Since 1999, Commerce Partner has observed in more than 2,500 projects which functions really decide whether an order is placed or a supplier is changed. Here are the six most important expectations:
Personalized prices and terms: B2B buyers expect to see their individual contract prices, volume discounts, and payment terms directly in the shop – without having to ask sales. A wholesaler of electrical engineering products was able to reduce internal sales inquiries by 60 percent and at the same time increase order frequency by 35 percent by implementing customer-specific pricing. The ROI was reached after just eight months.
24/7 self-service: Buyers do not want to depend on office hours. They order in the evening, on weekends, or between appointments. Companies that offer self-service functions such as order history, invoice downloads, and delivery status tracking record average order volumes per customer that are 40 percent higher. The reason: customers order more often because the process no longer creates friction.
Mobile-first instead of desktop-only: More than half of all B2B research now starts on a smartphone. Buyers check availability, compare specifications, and place orders on mobile – often directly from the production floor or the construction site. An unoptimized shop leads to drop-offs and frustration. Companies with responsive B2B shops report 25 percent higher conversion rates among mobile users.
Real-time availability and delivery dates: "Is the product in stock, and when can I get it?" That question decides whether you get the order. B2B buyers no longer accept vague information. They expect precise delivery dates, ideally at item level. By integrating ERP data into the shop, a building materials wholesaler was able to reduce follow-up questions by 70 percent while increasing customer satisfaction by 45 percent.
Easy reordering and order templates: Repeat orders must be possible with one click. Features such as "repeat last order" or saved carts save time and reduce errors. Companies that implement such features see repeat purchase rates increase by up to 30 percent – while also easing the burden on sales.
Deep product data and technical documentation: B2B buyers need detailed information: technical drawings, data sheets, certificates, safety instructions. Companies that provide this data in a structured and searchable way reduce follow-up questions and speed up buying decisions. After integrating a Product Information Management system (PIM), a manufacturer of industrial components recorded a 50 percent reduction in support requests.
Typical traps mid-sized companies fall into
Despite clear expectations, many B2B e-commerce projects fail in the mid-market. The most common mistakes: companies start without a clear strategy and get lost in technical details. They choose systems that do not fit their processes, or they underestimate the integration with ERP and inventory management. Another classic mistake: trying to implement every function from the start instead of launching with a minimum viable product (MVP) and generating first sales quickly.
Many managing directors hesitate because they fear high investment costs or internal resistance. But while they wait, they lose market share to competitors who are already selling. The solution is not perfect systems, but pragmatic steps: start fast, learn, optimize. Over 26 years, Commerce Partner has learned that companies that set up a working shop in six weeks are more successful than those that plan for two years and then fail.
Another mistake is a lack of resources. Mid-sized companies rarely have an e-commerce department. They expect marketing or IT to handle it on the side – and then wonder why nothing moves forward. Here, only an honest decision helps: either create internal capacity or bring in external expertise that takes responsibility.
Conclusion: Act now – or lose customers
The numbers are clear: 44 percent of B2B buyers are willing to switch if the digital buying experience falls short. For mid-sized manufacturers and wholesalers, that means: if you do not sell digitally in 2026, you will lose revenue to competitors who do. The good news is that you do not have to start perfectly, but you do have to start. A working B2B shop with personalized prices, self-service, and mobile optimization can be set up in six weeks – if you work with experienced partners who know what matters.
