Reditus B2B Buyer Model | Section 1
Complex B2B purchases are, by definition, committee decisions
Complexity begins the moment unilateral authority disappears.
From the paper
The calendar invite had been on everyone’s schedule for weeks: Final decision: data security platform.
Ninety minutes. Seven attendees. The same group that had been meeting every other Tuesday since early fall.
Alex joined from a conference room on the third floor, laptop open, notes already organized. As VP of IT, he’d shepherded the evaluation from the beginning. Requirements gathered. Vendors shortlisted. Pilot completed. The numbers made sense. The platform reduced manual effort, closed known gaps, and integrated cleanly with existing systems. From a technical standpoint, the decision felt done.
Legal joined a few minutes late. Compliance was already on the call. Procurement had dialed in from another meeting. Finance came on muted, camera off. The security architect sat quietly, scrolling through the deck for the third time this month.
Alex walked through the summary. Nothing new. No surprises. The same recommendation he’d made twice already.
When he finished, there was a pause.
Compliance spoke first. “I’m still uncomfortable with the timing,” she said. “We’ve got an audit coming up. If anything goes wrong during implementation, that’s on us.”
Alex nodded. That concern had come up before. They’d addressed it. The vendor had references. The rollout plan was phased. Risk was lower than staying where they were.
Procurement jumped in next. “We’re fine with the vendor,” he said, “but the contract language around data residency still needs tightening. Legal hasn’t signed off.”
Legal cleared her throat. “We’re not blocking,” she said carefully. “We just need more clarity. If there’s an issue, liability isn’t evenly shared.”
Finance unmuted. “From a budget perspective, this is fine,” he said. “But if we defer to Q2, it helps smooth some other pressure we’re under.”
The security architect finally spoke. “Technically, this is the right solution,” he said. “But if we’re being honest, the current system hasn’t failed us yet.”
Alex felt the familiar tightening in his chest. None of this was new. None of it contradicted the value of the solution. And yet, the room felt heavier than it had a month ago.
He looked at the faces on the screen. No one seemed opposed. No one was advocating strongly either. Everyone had a reasonable point. Each concern, taken alone, was manageable.
Taken together, they formed something else.
“So,” Alex said, trying to keep his tone neutral, “what do we need to see to move forward?”
Silence again. Not awkward. Just real.
Compliance glanced down at her notes. Legal avoided the camera. Finance shrugged slightly. Procurement suggested revisiting after the audit. Someone proposed another check-in next month.
The meeting ended the way the last one had: action items, follow-ups, no decision.
After the call, Alex sat alone in the room longer than he needed to. He replayed the conversation, trying to pinpoint what had shifted. The value was still there. The risks were understood. The recommendation hadn’t changed.
And yet, momentum had quietly evaporated.
Nothing had gone wrong.
So why did nothing move?
A B2B purchase is complex when no single person can make the decision alone. That is the defining feature. Not deal size or contract length. Not enterprise vs SMB.
Complexity begins the moment unilateral authority disappears.
In these situations, multiple individuals participate in the decision. Each does so in a different way:
- Some must approve.
- Some can veto or constrain.
- Some influence direction without formal authority.
- Some are responsible for execution after the decision is made.
- Each of these roles shapes the outcome, even if none of them “owns” the decision outright.
This matters because it defines the correct unit to focus on. The unit is not the company. It is the individual operating inside a system.
The rational-committee counterfactual
A common assumption in B2B selling is that buying committees behave like unified, rational decision-makers. Under this view, individuals debate, share information, weigh tradeoffs, and converge on the option that is best for the organization.
If this were true, several things would reliably happen:
- Decisions would converge as information increased.
- Late-stage objections would diminish, not intensify.
- Decision speed would correlate primarily with data quality and clarity.
- But that is not what experienced sellers observe.
In practice:
- Objections often appear late, after months of alignment.
- Additional information can stall or reverse momentum.
- Decisions slow down even when data is strong and consensus seems close.
These patterns are not edge cases. They are the norm in complex deals.
What this tells us
If committees behaved as single rational agents, these outcomes would be rare. Instead, they are persistent and predictable.
That tells us something important: Committee behavior cannot be explained by treating the group as a single rational decision-maker.
Complex B2B decisions do not fail or stall because organizations are irrational. They behave this way because individuals within the system are optimizing for different outcomes, under different constraints, with different consequences attached.
Understanding complex buying starts here. You can’t model a committee like a person.
The company doesn’t decide. The org chart doesn’t decide. A group doesn’t decide. Individuals do; inside a system that constrains what they can tolerate.
