B2B Buyer Expectations in 2026: What the Research Shows

DEFINITION

Digital self-service ordering

An order channel where the buyer independently selects products, applies account-specific pricing, and submits a purchase order through a web portal or API — without involving a sales representative or customer service staff in the transaction itself.

DEFINITION

McKinsey rule of thirds

McKinsey's finding that B2B buyer channel preferences split roughly into thirds: approximately one-third prefer in-person sales interactions, one-third prefer remote video or phone interactions, and one-third prefer fully digital self-service. No single channel dominates.

DEFINITION

AI agent purchasing

Automated procurement where AI systems — rather than human buyers — identify needs, evaluate suppliers, and execute purchase orders. Gartner projects AI agents will intermediate $15 trillion in B2B spending by 2028.

The 83% Preference That Isn’t Showing Up in Revenue

Gartner’s 2024 research is direct: 83% of B2B buyers prefer digital ordering. That figure has grown year-over-year since 2020 and shows no sign of reversing. Yet Digital Commerce 360 and Forrester consistently peg U.S. B2B eCommerce at 16-17% of manufacturing and distribution revenue.

The gap between buyer preference and actual channel usage is not a measurement artifact. Buyers want digital but are often forced onto phone and email channels because their supplier’s infrastructure cannot handle the complexity of their actual transaction requirements.

Every manufacturer and distributor evaluating their ordering channels needs to start there. The question is not “do our buyers want online ordering?” — they do. The question is “can we implement it in a way that actually works?”

The Generational Shift in Procurement

71% of B2B buyers are now Millennials or Gen Z (commercetools, 2025). This demographic shift matters for one practical reason: their baseline expectation for what a digital experience should look like was set by consumer applications, not legacy B2B portals.

Older buyers who grew up placing orders by phone or fax have tolerance for friction that younger buyers do not. They value rep relationships and may prefer a call with someone they know. That preference is real and will remain a segment of the market.

But 71% of buyers coming from a cohort that expects the ordering experience to be as functional as their consumer apps means the tolerance for clunky portals, mismatched pricing, and broken checkout flows is systematically declining. When McKinsey found 54% of B2B buyers willing to switch suppliers over poor digital experience, that finding is mostly a reflection of this demographic reality.

The McKinsey Rule of Thirds

McKinsey’s B2B Pulse research introduced a useful framing: buyer preferences split roughly into thirds. Approximately one-third prefer in-person sales interactions. One-third prefer remote human interactions — phone or video. One-third prefer fully digital self-service.

The practical implication is that no single channel dominates, and pushing all buyers to digital self-service will alienate the two-thirds who want human contact for at least part of their procurement process. The winning strategy is omnichannel: make self-service excellent for buyers who prefer it, while keeping human touchpoints available for those who do not.

What this means for distributors: the goal of a self-serve portal is not to replace your sales team. It is to handle routine reorders and straightforward transactions so your sales team’s time goes to the relationships and complex situations that actually require human judgment.

What Buyers Are Willing to Buy Digitally

One of the more significant findings from McKinsey’s 2024 B2B Pulse Survey: 39% of B2B buyers are willing to spend $500,000 or more on a single digital order, up from 28% just two years prior. This dismantles the assumption that digital channels are for small-value reorders while large purchases require in-person negotiation.

Buyers are not skeptical of digital channels for high-stakes transactions. They are skeptical of specific implementations that have given them bad experiences.

The 39% figure is also a ceiling rather than a floor. As buyers gain confidence in suppliers’ digital infrastructure, willingness to place large orders digitally will continue growing. Distributors who invest in capable ordering infrastructure now are building the trust relationship that will matter when a buyer is ready to place a $200,000 purchase order through a portal.

Why the 16% Gap Persists Despite Buyer Preference

The supplier-side barriers are well-documented, even if rarely discussed openly in the industry.

ERP integration complexity: Most mid-market ERPs were built for internal operations, not customer-facing ordering. Connecting an eCommerce interface to pricing tables, inventory availability, customer-specific terms, and order routing is technically non-trivial. Gartner estimates 70% of ERP implementation projects fail to meet business goals.

Platform mismatch: Many distributors who have tried digital ordering used consumer-oriented platforms — primarily Shopify — that require extensive app configuration to handle B2B requirements like net terms, tiered pricing, and custom catalogs. The result is fragile integrations that break under volume or edge cases.

Budget constraints: 41% of mid-market distribution and manufacturing companies cite cost as the primary barrier to building eCommerce capability. Enterprise platforms price at enterprise scale. The gap between “can’t afford it” and “can afford it” has historically been wide.

Customer resistance: Accenture research found 64% of B2B organizations report that long-term customers resist switching from their established ordering process. A buyer who has faxed POs for 15 years has a workflow built around that process. Getting them to change requires the portal to be meaningfully faster and easier, not just equivalent.

The Error Problem: Bad Portals Are Worse Than No Portal

Sana Commerce’s 2024 research introduced a finding that deserves more attention: 68% of B2B buyers have been discouraged from ordering online due to errors they encountered on supplier portals. 91% have experienced errors that prevented completing an online order.

This is not a buyer behavior problem. It is a portal quality problem. Distributors who have launched portals with incorrect pricing, broken inventory sync, or checkout failures have trained their buyers to distrust digital ordering. Those buyers went back to calling in orders — and they took that negative experience with them when evaluating other digital channels.

The implication: getting to digital ordering is not enough. Getting to digital ordering that works correctly is the threshold. A portal with 33% order error rates — the figure Sana Commerce found for poorly integrated B2B online ordering — is worse than careful manual entry because it adds customer frustration on top of the operational cost.

The AI Agent Horizon

Gartner’s projection that AI agents will intermediate $15 trillion in B2B spending by 2028 — and potentially handle 90% of B2B purchases within three years — is the forward-looking dimension of the channel preference shift.

An AI agent executing procurement cannot call your phone line. It needs an API or a structured digital interface. The 2030 Gartner prediction that 75% of B2B buyers will still prefer human interaction for sales experiences suggests a hybrid future rather than fully automated procurement. But the portion of spend flowing through automated channels is growing, and suppliers without machine-readable ordering infrastructure will be structurally excluded from those transactions.

For distributors evaluating their ordering infrastructure, this is the medium-term forcing function. The immediate case for digital ordering is the $26-$34 per manual order cost differential. The 3-5 year case is structural: buyers — and the AI agents acting on their behalf — will route around suppliers whose ordering process cannot be accessed programmatically.

What This Means for Ordering Infrastructure Decisions

Buyer preferences are clear, generational momentum is real, and the risk of poor digital execution is higher than the risk of delayed adoption. The question is not whether to build ordering infrastructure, but how to build it in a way that actually meets the 83% preference without creating the 91% error experience that drives buyers back to phone orders.

We built OrderDock around this specific problem: B2B ordering complexity handled correctly — account-based pricing, net terms, matrix ordering, purchase order workflows — without the implementation cost and integration fragility that has made most mid-market digital ordering attempts fail. The buyer expectation is already there. The infrastructure question is whether yours can meet it.
