A B2B vendor can be well known. It can make the shortlist. It can become the preferred option of the person leading the buying process. And the purchase can still fail.
Complex B2B decisions increasingly involve networks of people who evaluate different dimensions of the same choice: business value, economics, technical fit, security, legal exposure, implementation risk and organisational readiness. According to Forrester’s State of Business Buying 2026, a typical buying decision now involves 13 internal stakeholders and nine external influencers on average, with participation increasing as purchases become more complex or strategic.
Direct Answer
Identifying a preferred supplier does not end the buying challenge. In complex B2B purchases, the next challenge is creating enough shared confidence across the buying group to proceed.
A champion may prefer the vendor while Finance questions the economics, Security sees unacceptable risk, Procurement challenges the commercial model, IT doubts integration feasibility and executives question whether the initiative deserves priority.
The group does not need every stakeholder to value exactly the same things. It needs different concerns and different evidence to resolve into one decision the organisation can collectively justify, approve and implement. For Marketing and Sales, that changes the objective from persuading an individual buyer to helping an entire decision system move forward.
Key takeaways
- B2B buying increasingly involves larger internal and external networks rather than one identifiable decision-maker.
- Larger buying groups are not inherently a problem, and they can improve decisions when different perspectives are successfully integrated.
- Individual or subgroup preference does not guarantee organisational approval.
- Role-specific evidence matters, but it has to connect to a shared decision rather than reinforce isolated stakeholder priorities.
- The commercial objective is increasingly not only to become preferred, but to become a defensible and actionable choice.
Buying groups are becoming buying networks
Traditional B2B marketing usually simplifies the decision into a manageable set of personas: the champion, the economic buyer, the technical evaluator and the procurement contact. Real buying environments are considerably wider.
Forrester’s 2026 buyer research reports that the typical buying decision now involves 13 internal stakeholders and nine external influencers, with the number rising for more complex or strategic purchases. 6sense reaches the same directional conclusion using a different methodology, describing an average buying group of roughly 10.1 people evaluating around 5.1 vendors (6sense B2B Buyer Experience Report 2025). These numbers should not be combined into a single universal benchmark, but both studies point toward the same structural reality: complex B2B purchases are organisational decisions rather than individual ones.
Larger buying groups are not inherently dysfunctional. Forrester found that 94% of buyers in groups of six or more reported benefits such as broader perspectives, shared validation effort, better ability to secure budget and a greater likelihood of approval. The challenge is not stakeholder diversity itself, but whether those perspectives can be integrated into one decision.
A vendor may not be trying to win one decision. It may be trying to survive several interconnected evaluations happening inside the same purchase. The CFO asks whether the expected value justifies the investment. Security asks whether the risk is acceptable. IT asks whether it will work with the existing architecture. Procurement asks whether the commercial terms are defensible. The business sponsor asks whether this solves a problem important enough to act on. Users ask whether it will actually improve the way they work.
All of those people can evaluate the same vendor correctly from their own perspective and still arrive at different conclusions.
Individual preference is necessary, but not sufficient
The first competitive challenge is getting someone inside the organisation to prefer the vendor. The second is whether that preference can survive organisational evaluation. The difference matters because a buying group can agree that a supplier is attractive and still decide not to proceed.
Gartner provides strong primary evidence on the underlying mechanism. In a survey of 632 B2B buyers, 74% of buying teams demonstrated “unhealthy conflict”, which Gartner defines as situations where members have conflicting objectives, disagree on the right course of action or are overruled by external decision-makers. Buying groups that achieved consensus were 2.5 times more likely to describe the resulting deal as high quality (Gartner Sales Survey, May 2025).
The conclusion is consistent across the research. The threat to a deal is not only another supplier. It can be the buying organisation’s inability to become sufficiently confident in its own decision.
The old preference model and the collective-confidence model
| Dimension | Individual-preference model | Collective-confidence model |
|---|---|---|
| Primary focus | Champion or individual decision-maker | Buying group and wider buying network |
| Success signal | “They prefer us” | “The organisation can support this choice” |
| Primary question | Which vendor do I prefer? | Can we justify, approve and implement this decision? |
| Marketing role | Create awareness and preference | Create preference and provide evidence that supports collective validation |
| Sales emphasis | Persuade the buyer | Validate the choice and help the group resolve value, risk and feasibility |
| Evidence model | General case for the vendor | Role-relevant evidence connected to a shared business case |
| Objections | Barriers to Sales progression | Signals of unresolved organisational uncertainty |
| Competitive alternatives | Other vendors | Other vendors, internal build, existing solution, delay and status quo |
| Late-stage risk | Losing vendor preference | Failing to turn preference into organisational commitment |
| Desired outcome | Preferred supplier | Defensible, approved and actionable choice |
Buying groups can reach consensus twice
One of the most useful findings comes from 6sense’s 2025 Getting to Yes research, which describes two distinct points of consensus.
The first occurs before seller contact, as buying groups develop a preferred supplier through internal research and deliberation. In the study, 94% had ordered their shortlist before talking with sellers, and close to 80% eventually stayed with their original favourite.
That is not the end, because the buying group then has to validate the decision. 6sense found that speaking with sellers was the activity buyers most frequently identified as helping their teams reach consensus. The researchers interpret seller involvement as a second validation point: buyers already have a preliminary preference, but they need answers to unresolved questions before they can confidently proceed.
This explains why early preference and late-stage decision confidence are different commercial problems. A company can win the first and still lose the second.
Different stakeholders need different evidence, not different decisions
A common response to larger buying groups is to create increasingly personalised content: CFO content, CISO content, CTO content, procurement content, CEO content. The basic logic is reasonable, since different roles have different questions.
Gartner’s research reveals an important limitation. In its 2025 B2B buyer study, content tailored for buying-group relevance had a positive effect on consensus, while individual-level relevance had a reported 59% negative impact on buying-group consensus, because highly individualised messages can reinforce existing stakeholder perspectives instead of helping members understand one another. Buyers who experienced buying-group relevance were three times more likely to report a high-quality deal.
That produces a more useful rule for decision content. The buying group does not need identical evidence. It needs different evidence that resolves into the same decision.
Finance still needs economics, Security still needs risk information, IT still needs technical evidence and users still need implementation confidence. Those arguments have to connect, though. A CFO should be able to understand how implementation risk affects economic value. Security should be able to understand why the remaining risk is proportionate to the expected business outcome. The sponsor should understand why the value is strategically important and operationally feasible.
The objective is not only stakeholder-specific communication. It is role-relevant evidence connected through a shared decision framework.
New stakeholders can also reopen an apparently mature buying process. A late-entering Security, Finance or Procurement participant may bring new research, questions and risk criteria, including AI-assisted research, forcing the group to revisit assumptions that appeared settled.
Decision content should help the buyer build internal support
Buyers use content to help other people support the decision. The 2025 Edelman-LinkedIn B2B Thought Leadership Impact Report found that among hidden decision-influencers in its U.S. research:
- 51% said high-quality thought leadership helped them convince C-level executives to support their choice of vendor.
- 52% said it helped them convince other decision-makers involved in vendor vetting.
- 79% said they would be more likely to advocate for a proposal during an RFP when the company consistently produced high-quality thought leadership.
This reframes part of the role of thought leadership. The buyer does not only consume expertise to evaluate the supplier; they use that expertise to build support for the decision internally. For CMOs, that expands what sales enablement means. Decision content should enable the buyer, not only the salesperson.
Proof becomes more important as the buying group expands
Assertions are relatively easy to communicate, and collective confidence usually requires something more concrete. Forrester’s 2026 research found that Procurement acts as a decision-maker in 53% of business buying cycles rather than appearing only at the end to negotiate price, and that more than 60% of buyers use some form of trial to evaluate solutions, rising to 78% for purchases of $10 million or more.
Trials are only one form of evidence. Depending on the purchase, buying groups may need a realistic pilot or proof of concept, customer reference conversations, security or compliance evidence, architecture reviews, implementation plans, commercial scenarios, clear ROI assumptions, migration plans, documented customer outcomes, or direct access to the experts who will be responsible for delivery.
The purpose is not simply persuasion. Evidence allows each decision participant to answer a harder question: can I support this decision from the perspective of the responsibility I carry? That is very different from asking whether the vendor’s presentation was convincing.
A useful way to understand collective confidence
Once a supplier has become preferred, the buying group may still need confidence across several dimensions.
Problem confidence. Is the problem important enough to justify action? A buying group can like the vendor while deciding that the project itself should not happen.
Vendor confidence. Can this supplier actually deliver what it claims? This requires expertise, experience, evidence and a credible delivery model.
Economic confidence. Can the expected value justify the cost and the opportunity cost? The business case has to survive financial scrutiny, not merely sound attractive.
Risk confidence. Are security, compliance, operational, legal and commercial risks sufficiently understood and acceptable? Different specialist stakeholders may own different parts of that answer.
Implementation confidence. Can the organisation realistically execute the change? A strong solution can still lose when implementation appears too disruptive, too uncertain or insufficiently resourced.
These forms of confidence are related, and weakness in one can undermine the whole decision. Strong ROI with unacceptable security risk does not produce approval. Low technical risk with no compelling business problem does not produce urgency. A capable vendor with an unrealistic implementation plan does not get chosen. The decision becomes durable when the buying group can connect these different questions into one credible case for action.
What should CMOs and boards change?
First, stop treating the champion as the buyer. Champions remain important, and they operate inside a wider system of approval, risk and influence.
Second, examine decision evidence rather than persona content. For every strategic offer, ask whether the organisation has enough evidence to help Finance, Security, IT, Procurement, the sponsor and users answer their own questions, and whether those answers connect to the same business case.
Third, look beyond opportunity creation. Which stakeholders tend to join later? Which questions repeatedly reopen deals? Where does preference weaken? Which evidence repeatedly has to be created manually by Sales? Where do opportunities stall without a competitor winning? And what does “No Decision” actually mean in your win-loss data?
Fourth, recognise that consensus is not universal enthusiasm. Stakeholders do not need to love the vendor equally. They need enough shared confidence to support the decision.
FAQ
What is collective decision confidence?
Collective decision confidence is the point at which the relevant buying-group members have enough shared confidence in the problem, vendor, economics, risk and implementation to support and act on the decision. It does not require everyone to value the same things or prefer the supplier for the same reasons. It requires those different reasons to become compatible with one organisational choice.
Is consensus the same as every stakeholder preferring the same vendor?
No. Different stakeholders can hold different personal preferences and still support the same final decision. Gartner’s research suggests that consensus is associated with better deal outcomes, while unresolved conflict creates delays and poor results. The objective is sufficient alignment to justify, approve and implement the choice, not identical enthusiasm.
Should Marketing create separate content for every buying-group role?
Role-relevant evidence is useful, and isolated individual personalisation is not enough on its own. Gartner found that buying-group relevance supported consensus, while individual-level relevance could reinforce separate stakeholder perspectives and reduce alignment. The better approach is to answer each role’s legitimate questions while connecting those answers to one shared decision.
Does Sales still matter if buyers already have a preferred vendor?
Yes. 6sense found that speaking with sellers was the activity buyers most frequently identified as helping their teams reach final consensus, even though the preliminary preferred vendor was usually chosen before seller engagement. That makes seller expertise especially important for validation, context and unresolved decision questions.
What matters now
The final challenge in complex B2B buying is increasingly not whether the company can persuade someone to prefer it. It is whether enough people inside the organisation can justify making the choice together.
That distinction matters because preference and commitment are different outcomes. A supplier can become visible, enter the shortlist and become preferred, and still fail if the buying organisation cannot establish enough shared confidence in the business problem, the vendor, the economics, the risk and the implementation.
HiFuture describes these as two distinct strategic GTM battles. The first is Win Early Preference: becoming understood, seriously considered and preferred before or around buyer engagement. The second is Become Chosen: turning that preference into a choice the wider buying group can validate, endorse, approve and implement.
HiFuture uses Collective Decision Confidence to describe the conditions required for the second battle: Problem Confidence, Vendor Confidence, Economic Confidence, Risk Confidence and Implementation Confidence working together rather than in isolation.
The framework names a wider market reality. The buying group does not need identical evidence. It needs different evidence that resolves into the same decision.
For CMOs and boards, that explains two fundamentally different forms of commercial failure. A company can lose before it knows the opportunity exists. Or it can enter the opportunity as the preferred supplier and still fail, because the buying organisation cannot confidently move forward.
That is the shift from Individual Vendor Preference to Collective Decision Confidence.
