B2B Buyer Journey Benchmarks

B2B buyers in 2026 want proof of return before they sign, and finance is the reason. Software buyers who have watched a CFO undo an approved purchase now expect a positive ROI within six months of signing, and nearly half of buyers say their CFO vetoed an approved software purchase in the last year. No study published in 2026 measures what share of all B2B buyers require an ROI benchmark before a deal closes, and none publishes funnel conversion or win rate benchmarks. Below are the 2026 figures that do exist: what buyers expect as proof, where deals slow down and how shortlists turn into purchases.

B2B buyer journey benchmarks at a glance

Every figure below comes from research its publisher released in 2026.

Do B2B buyers expect ROI benchmarks before the deal closes?

Increasingly, yes, and the pressure comes from finance rather than from the buying committee's champion. G2's 2026 survey of 1,038 B2B decision makers found that three in four buyers who have experienced a late-stage veto now expect a positive ROI within six months of signing a contract. That figure describes buyers who have watched a CFO undo a deal, not every buyer, but the group is large: nearly half of buyers say their CFO vetoed an already-approved software purchase in the last year. Vetoes run at 54% in organizations with a dedicated budget for LLMs and AI tokens, against 29% in those without one.

The same buyers want to limit their exposure while they wait for the return. Buyers who have been through a veto push for contract terms under 12 months at more than double the rate of other buyers, 40% against 18%. Across all software buyers, 70% say the pace of AI is pushing them toward shorter contracts, and 29% want terms under 12 months. Preference for outcome-based pricing more than doubled in a year, from 11% to 23%.

Sellers see the same shift from the other side of the table. In Salesforce's State of Sales report, published in February 2026, 69% of sales professionals say measurable ROI is more important to customers than it was a year earlier.

Trials are where buyers look for that proof, and they are not a reliable close. More than 60% of business buyers report purchasing some form of trial, according to Forrester's State of Business Buying 2026, yet just over a third of those buyers planned to convert to a fully paid version with the same provider.

Finance has reason to be wary. Only 12% of organizations consistently assess AI value against its cost, according to KPMG's Global AI Pulse survey of 2,131 senior leaders, published in September 2026, and 35% of organizations report difficulty quantifying and demonstrating AI ROI to stakeholders, according to IDC research published in April 2026.

How long is the B2B buying journey in 2026?

Longer, though no 2026 primary source puts a number of days on it. In Salesforce's 2026 survey of 4,050 sales professionals, 57% say the sales cycle is getting longer, because customers take longer to decide. Forrester's State of Business Buying 2026 describes the same pattern: buying groups are expanding and decision cycles are growing.

Evaluation is now the longest stage for 40% of software buyers in G2's 2026 survey, ahead of research at 36% and the decision itself at 22%. IT security review is the biggest single source of delay, cited by 39% of buyers and by 50% of enterprise buyers, followed by budget approval at 32% and implementation planning at 25%.

The number of people involved explains much of the wait. Forrester reported in February 2026 that 73% of purchases involve three or more departments. For the full picture of who sits on a buying committee in 2026, see our B2B buying committee benchmarks.

How do B2B shortlists turn into purchases in 2026?

AI chatbots now shape many shortlists, and the shortlist usually decides the deal. Buyers who sourced software recommendations from AI chatbots bought from their initial shortlist in at least three of their last five purchases 80% of the time, against 65% for buyers who did not, according to G2's 2026 survey.

Getting onto that list has changed. In G2's April 2026 survey of 1,076 B2B decision makers, 69% of buyers chose a different supplier than they first planned because it was part of a chatbot's recommendation, and one in three bought from a supplier they had never heard of before. Four in five said AI chatbots sped up their purchasing decision, and 83% felt more confident in their final choice.

The research behind those choices has moved too. 71% of software buyers say they rely on AI chatbots for research, up from roughly 60% seven months earlier, and 53% say their research is more productive with AI search than with traditional search, up from 36%. Being named matters: 85% think more highly of a supplier that an AI chatbot cites in its answer. Forrester found in January 2026 that 61% of business buyers use private AI tools their own organization provides.

AI is helping buyers evaluate but not yet buying for them. 61% of buyers use or plan to use AI agents in the buying process, yet only 9% are comfortable letting an agent execute a purchase within approved guardrails.

What are the B2B funnel conversion and win rate benchmarks for 2026?

We found none published in 2026 by a primary source. The funnel conversion rates in circulation, from lead to MQL to SQL to opportunity to closed-won, come from surveys fielded in 2024 or 2025, from aggregates published by sales software companies or from roundups that restate older figures without a method. The same is true of win rates and of the share of the buying journey completed before a buyer talks to a seller. We left them off this page rather than present an old number as current.

The closest 2026 measures are the ones above: just over a third of trial buyers planning to convert, buyers buying from their initial shortlist 65% to 80% of the time, and 69% switching suppliers because a chatbot recommended a different one. Each describes a step in the journey, not a full funnel.

How to benchmark your own buyer journey

Your own pipeline is the benchmark that matters, and it is the one you can measure this quarter. This is The Starr Conspiracy's practitioner guidance.

1. Measure from the first recorded touch to closed-won, by deal size. A single cycle length hides the difference between a renewal and a new enterprise deal.
2. Record when finance first appears in each deal. Deals where finance arrives after the evaluation are where late vetoes come from.
3. Track trial-to-paid conversion separately. If it sits near the just-over-a-third that Forrester's buyers planned, the trial is not doing the proving.
4. Ask every new opportunity where it first heard of you, including AI chatbots. Most AI-assisted research leaves no referral trail in analytics.
5. Log every stage where a deal waits, and why. Security review, budget approval and implementation planning are the delays G2's buyers name most.
6. Compare quarter over quarter rather than against an industry average. Your trend is evidence; a borrowed average from a different market is not.
