Business case for the buyer: arm your champion

Buying groups are big, and they have become a problem in their own right. Forrester's January 2026 research puts the figure at 13 internal stakeholders and nine external influencers per decision, more in larger deals. The same research finds that 94 percent of buyers in groups of six or more see clear upsides to the group: broader perspectives, shared effort in validating the solution, a better shot at securing budget and a higher chance of approval. In RAIN Group's June 2026 study, 79.5 percent of sales leaders name more decision makers and committees as a challenge, and 82.4 percent say the same about deals lost to no decision. Those two numbers belong together. A group makes no decision when nobody in it has a document to decide on.

Why your champion needs a document, not a deck

Your deck was built for a meeting where you are in the room to field the questions. Your champion needs something different: a document the CFO can read in ten minutes, forward to IT and quote in an email to the CEO. Gong Labs' multithreading data shows what is riding on it: 77 percent of deals involve multiple contacts, won deals have twice as many buyer contacts as lost ones, and strategic deals average 17 contacts. You will never meet all 17. The document will.

The one-page decision document, in six parts

1. The problem, in the customer's own numbers. Not 'inefficient follow-up' but 'quotes sitting unanswered for 19 days on average, measured in our CRM in October'. The champion's words and the champion's figures, never yours.
2. The cost of doing nothing. What the problem costs per month, and what it costs to push the decision into the next budget year. This is the line that turns waiting into a choice someone has to own.
3. The alternatives. At least three: do nothing, build it in-house, and another vendor. A leadership team does not trust a document with a single option, and a champion who has written the competitor in personally stands on firmer ground when the question comes up.
4. The recommendation, with total cost over the contract term and payback period in months. One number for what it costs, one for when it pays for itself, both worked out from the figures in part one.
5. The risks and how they are handled. What could go wrong, and the answer that is already in place: a pilot in one department, the notice period, how the data comes back, who owns the rollout.
6. Timeline and the decision required. Which decision, by whom, by when, and what happens in January if the decision is made in November.

One page. If it spills onto a second, the document has three problems: nobody will read it, nobody will forward it, and it shows that the two of you have not yet agreed on what matters.

How to write it together

Write the document together, in a thirty-minute meeting, in the champion's own template if the company has one. You bring the structure and the numbers from discovery; the champion brings the language, the priorities and the knowledge of who will object to what. Start with parts one and two, because they belong to the customer. Write part three honestly: if the competitor is cheaper, that goes in, with the reason for the recommendation right beside it. Let the champion write part six alone, since it is their timeline that has to hold. Then send the finished document as a file, not as a link into your system, so it can be forwarded without anyone having to log in.

What AI search has changed

Forrester describes generative AI search as today's starting point for B2B buyers, while leaders lean more and more on their internal and external networks to justify and de-risk decisions. Gartner's buyer research, as reported by Demand Gen Report in May 2026, paints the same picture: 69 percent of B2B buyers want to validate AI-generated insights with a sales rep, and buying groups with low dysfunction are 13 times more likely to report high-quality deals. The document is where that validation takes place. It is also where a group's dysfunction shows: if parts three and five are empty, you know the group has not talked to each other yet.

Rehearse the champion's presentation, not just your own

This is the step almost everyone skips. The champion has five minutes to present the document to people who will ask questions you never get to hear. Offer a dry run: 'Shall we take fifteen minutes where you walk me through it and I play your CFO?' Ask what a CFO asks, in the tone a CFO uses: what does it cost in total, what happens if it does not work, why now. Deloitte's CFO survey for the second quarter of 2026 shows what is waiting in that room: 44 percent of the North American CFOs surveyed use AI in their planning and budgeting, and 46 percent worry most about cost uncertainty and a lack of cost transparency. A champion who has already answered those questions once walks in calm.

Three signs the document is working

• The champion edits it. A document that comes back untouched has either not been read or has not become the champion's own.
• Someone else gets in touch. When the IT manager or procurement rings you with a question, the document has travelled, which is the whole point.
• Part six carries a date the champion set. A timeline you proposed rarely holds; one they wrote themselves holds far more often.

Rehearse in front of an audience that answers back

What you need to be able to do is present the six parts in five minutes, handle the questions that follow, and then coach someone else to do the same. In Salesprep you can run the presentation for an AI audience that interrupts and asks questions, and get scored on structured delivery, question handling and audience adaptation among other things; the Presentation module is available on Team Pro. The Negotiation module, also on Team Pro, trains the conversation about total cost and terms. The Cold call module is included in every plan with three free calls.
