The B2B ecommerce landscape is undergoing a generational transformation; millennials — those born between 1981 and 1996 — have firmly taken control of corporate buying decisions, driving a new era defined by digital-first expectations, streamlined purchasing, and marketplace dominance.
According to LinkedIn’s 2025 B2B Buyer Report, millennials now make up 73% of all B2B buyers and 44% of final purchasing decision-makers. This demographic shift, from older Gen X and boomer buyers to digitally native millennials, is radically altering how B2B products are discovered, evaluated, and purchased.
“Millennials have grown up in a world of instant information and seamless online experiences,” says Greg Coticchia, CEO of Sopheon, in LinkedIn’s analysis. “They expect B2B interactions to be as intuitive and convenient as their personal shopping experiences. If companies can’t deliver that, they risk being eliminated from consideration before they even realize it.”
Self-directed research now dominates the B2B buying process. Millennials are replacing relationship-based sales with independent digital research. Salesforce’s State of the Connected Customer report found that 68% of millennial B2B buyers prefer self-service research tools over speaking to a sales rep, and many complete up to 70% of the buying process online before engaging with a supplier.
“The role of the traditional salesperson is evolving,” Salesforce noted. “Millennials want independence and transparency at every stage of the buying journey. Companies that fail to provide seamless online research and transaction capabilities will fall behind.”
How millennials redefine B2B ecommerce expectations
Millennials are also highly selective about engaging vendors. A 2024 Gartner Future of Sales report predicts that by 2026, 80% of B2B sales interactions will take place across digital channels, including self-service ecommerce platforms, chatbots, and online marketplaces. Gartner emphasized that millennials reward companies that make it easy to research, compare, and buy without the traditional friction points of B2B selling.
The rise of B2B marketplaces is another direct outcome of millennial preferences. Applico Inc.’s 2024 study showed that millennials are 2.2 times more likely than baby boomers to purchase on marketplaces such as Amazon Business, Thomasnet, and Faire. Applico’s analysts explained that the marketplace model resonates because it offers breadth, efficiency, and user control — hallmarks of what millennials value.
The 2024 edition of Digital Commerce 360 B2B Marketplace Report reinforced this finding, reporting that more than half of B2B sellers are actively investing in either building their own marketplace or selling through third-party platforms to meet demand.
Millennials’ B2B buying preferences
For millennial buyers, efficiency is just as important as price. ShipperHQ’s Millennials and B2B Buying Report found that 78% of millennials said they would switch suppliers if a competitor offered faster delivery, clearer pricing, or better digital checkout experience.
Karen Baker, founder and CEO of ShipperHQ, said the consequences of not adapting are severe.
“This generation has no patience for opaque pricing models or sluggish fulfillment,” Baker said. “If you don’t deliver a frictionless experience from search to checkout to delivery, they’ll find someone who does.”
Millennials also expect full visibility into every step of their purchase journey. Companies such as Fastenal, Grainger, and MSC Industrial are responding by investing in real-time inventory tracking, two-day shipping guarantees, and mobile-friendly order management to better align with millennial preferences. ShipperHQ’s report found that 65% of millennials expect live updates on their orders. That mirrors expectations consumer giants like Amazon and Walmart have set.
Social proof and peer influence have become critical in the B2B purchase decision. Millennial buyers are not easily swayed by polished brochures or corporate sales pitches. They rely heavily on peer reviews and user-generated content. Research from Lead Forensics found that 85% of millennial B2B buyers consult peer reviews, case studies, or testimonials before finalizing purchases. Lead Forensics reported that millennials trust peer recommendations far more than traditional marketing, and that they seek authentic voices and proof points rather than polished promotional content.
This trend is fueling the growth of customer advocacy programs, community forums, and user-generated content initiatives among leading B2B brands. Companies like HubSpot and Salesforce are seen as leaders in using customer communities to influence new buyers.
“Millennials want to see real experiences from real customers — not just a brand telling them how great it is,” Coticchia said.
How B2B ecommerce companies remain competitive
The new B2B ecommerce reality demands operational changes. Salesforce, LinkedIn, Applico, and Gartner collectively argue that companies must make significant shifts to stay competitive.
This includes modernizing websites for:
- Seamless mobile navigation and fast checkout
- Publishing comprehensive product information and transparent pricing
- Joining or building marketplaces to expand reach
- Integrating social proof directly into product pages
- Offering faster and more flexible fulfillment options that mirror B2C experiences
“Meeting millennial expectations isn’t optional anymore — it’s survival,” Coticchia said. “The companies that invest now in digital-first experiences will lead the next era of B2B commerce.”
Gen Z B2B buying behavior
While millennials dominate today’s B2B landscape, early signals suggest that Generation Z — born 1997 and later — are beginning to influence corporate buying patterns as well.
A 2025 report from Forrester Research found that 29% of B2B buyers under age 30 expect companies to offer AI-driven personalization, instant chatbot support, and mobile-native purchase experiences. Forrester emphasized that Gen Z buyers are true digital natives. They have zero tolerance for outdated websites, manual forms, or traditional sales delays.
“Gen Z buyers are bringing their consumer expectations into every B2B interaction,” said Lori Wizdo, vice president and principal analyst at Forrester. “They have grown up in a mobile-first, app-driven world, and they expect immediacy, hyper-personalization, and seamless experiences by default.”
Unlike millennials who witnessed the rise of the internet, Gen Z has never known a world without it. Their demands for real-time engagement, personalization, and digital self-service are expected to accelerate the ongoing transformation of B2B commerce even further.
Millennials have fundamentally reshaped B2B ecommerce, moving it toward transparency, speed, self-service, and marketplace-driven transactions. Their expectations have set new standards that are redefining how business gets done. As Gen Z buyers begin to gain more influence, those standards will likely become even more demanding.
Companies that embrace this generational shift now — by investing in technology, rethinking sales strategies, and putting digital convenience at the center of the customer experience — will be positioned to thrive. Those that delay risk becoming invisible to the very buyers who are shaping the future.
