    How B2B Buyers Use AI to Shortlist Vendors, and What B2B Service Firms Should Do

    How B2B Buyers Use AI to Shortlist Vendors, and What B2B Service Firms Should Do

    In B2B, the sale is often decided before your first call. Buyers research on their own, build a shortlist, and contact the vendors they already trust. More and more, AI tools do part of that research. Here is what the data says, how far it applies to service firms, and what to do about it.

    What the research says

    • 6sense's 2025 B2B Buyer Experience Report, as reported by G2, found that about 94% of buying groups had already picked a preferred vendor before speaking to a salesperson. Other coverage of the same research reports that in about 95% of purchases, the winning vendor was already on the buyer's day-one shortlist.
    • G2's buyer research found that 51% of B2B software buyers now start their research by asking an AI chatbot, up from 29% only months earlier.
    • In the same research, 69% of buyers said they chose a different vendor than the one they first had in mind because of what an AI tool told them, and one in three bought from a vendor they had not heard of before an AI tool surfaced it.
    • G2 also found that, among enterprise buyers, review sites were the top research source at 56%, just ahead of AI search at 55%. When buyers ranked what shapes a shortlist, review sites scored 15.1% and vendor websites 12.8%.

    Read these with care. The surveys are run by vendors with an interest in the topic. The strongest data covers software buyers and larger purchases. Your buyers may behave differently, so ask your own recent customers how they found you and whether they asked an AI tool.

    What it means for a B2B service firm

    Three things have to be true at the moment a buyer asks an AI tool for options. You have to be findable, you have to be described accurately, and you have to look credible. The first call is no longer where trust begins.

    What B2B firms need

    1. Clear positioning. One page that says who you serve, which problems you solve, what outcomes you deliver, and what you do not do. AI tools summarize what they can find, and vague copy produces vague summaries.
    2. Proof. Case studies with real clients, used with permission, measurable outcomes with dates, named testimonials, and credentials. Never invent any of these.
    3. Third-party presence. Reviews on the platforms your buyers use, directory listings, association pages, partner pages, podcasts, and press. G2's data suggests outside sources shape shortlists more than your own site does.
    4. Content that matches how buyers research. How to choose a provider, comparisons and alternatives, cost and timeline ranges, implementation questions, and who your service is not for.
    5. Consistent facts. The same company description, services, and locations on your website, LinkedIn, directories, and review profiles.
    6. Pages machines can read. See our October 14 article.
    7. Fast, informed follow-up. Buyers arrive having done their homework, so the first conversation should answer questions, not repeat the basics. Respond quickly, offer a booking link, and consider an AI assistant to qualify enquiries after hours. See our October 6 and 9 articles.
    8. Measurement. Test a fixed set of prompts monthly, add an AI option to your how did you hear about us question, watch branded search over time, and ask prospects on sales calls what they asked AI tools. Our October 2 article explains the prompt test.

    What to avoid

    • Fake reviews or paid mention schemes
    • Mass-produced generic content that says what everyone else says
    • Claiming results you cannot prove
    • Hiding how you price and package your work. See our October 8 article.
    • Slow follow-up on the leads you do earn

    A 30-day plan

    • Week 1: Run 20 prompts about your category and your company in the main AI tools, and write down what they say. Review your positioning page.
    • Week 2: Correct inconsistent facts across your profiles, and ask your five best clients for reviews on the platforms your buyers use.
    • Week 3: Publish two buyer guides, one on cost and timelines and one on how to choose a provider.
    • Week 4: Publish one case study, set up tracking, and schedule the monthly prompt test.

    Questions owners ask

    Is this only true for software? The best data is about software, but similar buying behavior is reported across B2B. Check it against your own customers.

    How long until we see leads? There is no reliable timeline, and B2B sales cycles are long. Track shortlist appearances and first conversations as early indicators.

    Do we need to be on every review site? No. Pick the two or three your buyers actually use.
