What is the B2B buying process

The B2B buying process is a non-linear, consensus-driven journey through 6 to 8 stages in B2B tech and enterprise services, from problem recognition to post-purchase evaluation, involving 6 to 10 stakeholders inside a buying committee. Modern buyers complete most of this process digitally, often guided by AI, before a seller is ever contacted.

Why the textbook definition gets it wrong

Most definitions you'll find online describe the B2B buying process as a clean six-step march: identify need, define requirements, evaluate options, negotiate, purchase, review. Tidy. Wrong.

Split that 17% across 3 or 4 shortlisted partners and any single seller gets roughly 5% of buyer attention. The other 95% happens in places you can't see: Slack threads, AI chat sessions, peer calls, and pricing pages opened late at night.

This is why The Starr Conspiracy maps buyer behavior to demand states rather than lifecycle stages. The demand state framework reflects what the buying committee is actually doing right now, not what a textbook says they should be doing next.

The 8 stages of the modern B2B buying process

Here's the map we use with B2B tech CMOs. The table is the quick view; details follow. Each stage is paired with the dominant buyer activity and the seller or marketer implication.

The stages are real. The order is not. A committee can be in stage 5 with one partner and stage 2 with another, simultaneously. Smaller deals collapse stages 3 through 6 into days; enterprise deals stretch them across quarters.

A short worked example of non-linear committee behavior

A committee reaches stage 5 with two shortlisted partners. Security review surfaces a data-residency requirement that wasn't in the original spec. The committee loops back to stage 3, rewrites requirements, and procurement resets the partner list. One incumbent shortlister falls off; a new partner is added at stage 4. The champion now has to re-sell the business case to finance because timeline slipped a quarter. Three stages, running in parallel, for the same deal. This is what "non-linear" actually looks like in the field.

Who actually makes the decision

Those stages don't move forward on their own. The committee does.

In complex enterprise purchases, there is no single decision-maker. Gartner ("The B2B Buying Journey," 2019) puts the average buying committee at 6 to 10 stakeholders, and for enterprise SaaS deals above $100,000 annual engagement value (ACV), The Starr Conspiracy's practitioner observation is that committees of 12 or more are common. Each stakeholder brings a veto, not a vote.

The roles you'll encounter:

• Champion, the internal advocate driving the process forward
• Economic buyer, holds the budget, usually a VP or C-level
• End users, will use the product daily and can kill adoption
• Technical evaluator, owns IT, security, data, and integration concerns
• Procurement, owns the engagement and pricing negotiation
• Executive sponsor, signs off, often involved only at the end

Marketing's job is not to talk to the champion louder. It is to give the champion the assets needed to sell internally to the other 9 people in the room. This is the practical difference between lead generation and demand generation, and it's where most B2B tech marketing programs leak pipeline. If your plan is "more nurture emails," you are not solving consensus, you are broadcasting.

How the B2B buying process changed from 2016 to 2026

Three shifts define the last decade.

Committee size grew. Gartner's 2016 research put the average B2B buying group at 6.8 stakeholders; by 2019 the same research line cited 6 to 10. Practitioner observation across The Starr Conspiracy's client base is that enterprise committees now routinely exceed 12.

Digital self-research deepened. Gartner (2019) reported buyers spend only 17% of journey time with potential partners. Sellers used to own the middle of the funnel; AI assistants and peer networks now own it.

Cycle length stretched. The Starr Conspiracy's practitioner view, working inside B2B tech buying committees, is that enterprise deals above $100,000 ACV now routinely run 6 to 12 months, with platform replacements stretching to 18. Pipeline coverage ratios built on 2019 assumptions will often miss 2026 targets.

What this means for your pipeline

A few implications matter for any B2B tech CMO planning 2026 budget.

The buying process starts long before a form fill. If your attribution model only counts touches after a marketing-to-sales handoff, you are blind to most of the journey. Fix this and you'll see fewer "no decision" losses, because you influence the requirements before they are written, often before security review surfaces and resets the spec.

AI is now a stakeholder. Buyers ask ChatGPT, Perplexity, and Claude for shortlists before they ever search Google. If your brand is not surfacing in those answers, you are not on the long list. This is why Answer Engine Optimization is now a line item, not a side project. The benefit: higher shortlist inclusion rate, which is the top-of-funnel metric that still matters in most categories.

And a watch-out: deal cycles are getting longer, not shorter. The Starr Conspiracy's practitioner observation is that enterprise deals above $100,000 ACV are stretching past 90 days, with many running 6 to 12 months. Build for committee reality and you'll improve consensus velocity, reduce stalled-deal risk, and stabilize forecast.

A rough rubric: if you are seeing high MQL volume and low opportunity creation, you are failing at stage 2 (think SQL created before security review, or a champion who can't get past internal exploration). If you are seeing strong opportunities and stalled late-stage deals, you are failing at stage 6.

Sources and benchmarks

• Gartner, "The B2B Buying Journey" (2019): B2B buyers spend 17% of their total purchase journey time meeting with potential partners. Across 3 to 4 shortlisted partners, any single partner receives roughly 5% of buyer time.
• Gartner, "The New B2B Buying Journey" (2019): Average buying group size of 6 to 10 stakeholders for complex B2B solutions.
• Gartner CSO research (2016): Earlier baseline buying group size of approximately 6.8 stakeholders, used here to show the trend toward larger committees.
• The Starr Conspiracy practitioner observation (2024 to 2026): Enterprise SaaS deals above $100,000 ACV frequently involve committees of 12 or more and cycle times of 6 to 12 months, based on client engagements.

The Bottom Line

The B2B buying process is a non-linear, committee-driven journey through 6 to 8 stages, dominated by digital self-research before any partner is contacted. Gartner (2019) found buyers spend only 17% of journey time with sellers, the rest with peers, AI, and content. For B2B tech CMOs, this means the old stage-gated handoff model is a measurement artifact, not a buying reality. Build for the committee, show up in AI answers, equip your champion. That is how The Starr Conspiracy helps clients protect conversion rates as committees keep getting bigger.

Related Questions

How long does the B2B buying process take?

Cycle length varies by deal size. SMB deals under $25,000 typically close in 30 to 60 days. Mid-market deals run 60 to 120 days. Enterprise deals above $100,000 ACV typically take 6 to 12 months, and complex platform replacements can stretch to 18 months or longer.

How many people are involved in a B2B buying decision?

Gartner (2019) puts the average B2B buying committee at 6 to 10 stakeholders. For enterprise SaaS, services, and platform deals, committees of 12 to 15 are common. Each stakeholder holds an effective veto, which is why consensus building, not persuasion of a single buyer, is the central marketing challenge. See the demand generation glossary for how to map content to committee roles.

What percentage of the B2B buying process is completed before contacting a partner?

Gartner (2019) found B2B buyers spend only 17% of their total purchase journey time meeting with potential partners. The rest is independent research, peer conversations, and increasingly AI-assisted shortlisting. Most committees have a clear preference before the first sales call.

How is the B2B buying process different from B2C?

B2B buying involves multiple stakeholders, longer cycles, larger deal values, and procurement and legal review. B2C is typically a single buyer making a fast, often emotional decision. The structural difference is the committee: B2B marketing must serve the buying group, not the individual.

How has AI changed the B2B buying process?

Buyers now use AI tools to generate partner shortlists, summarize product comparisons, and draft RFP requirements before any human seller is contacted. This compresses the early stages and makes Answer Engine Optimization a prerequisite for being considered. If your brand is not cited in AI answers, you are not on the list.

What's the difference between the B2B buying process and the B2B sales process?

The buying process is what the client does. The sales process is what the seller does. They run in parallel but are not the same. Most pipeline problems come from sales processes built around seller-stage gates rather than buyer-stage reality. Align the two or expect forecast slippage.
