The Buyer Presentation Has Five Readers

A buyer presentation is often written for one meeting and used afterwards as a reference file. In a complex B2B purchase it can move through procurement, due diligence and risk, finance, legal and sustainability. Each function opens it to answer a question of its own. Few need the whole presentation in the same order.

The exact group depends on the purchase. The five-reader model is a working test for long-term supply, project and offtake decisions. A technical evaluator, information-security team, tax adviser, operations lead or board may also have a formal review. Replace the five functions with the actual approval route before using the worksheet. Procurement tests the route to buy. Risk tests the exposures. Finance tests the budget and cash commitment. Legal tests the obligation and public wording. Sustainability tests the impact claim. The buying committee map linked below shows how to replace these five with the actual roles in an account.

What Your Buyer Has to Defend After You Leave the Room covers the champion who carries the case, and From Pilot to Purchase gives the one page they carry after a pilot. This guide covers the full presentation the five functions open.

Map the route before you build the file

The same offer can reach a buyer through different routes. A direct corporate sale, a formal request for proposals and an intermediary-led sale can bring the same functions into the decision in a different order. Map that route before you decide which section comes first.

Write five lines for the account. Who receives the first material. What they decide. Who receives it next. Which function can stop the purchase. Which document or source that function will ask for. The presentation should follow that route closely enough that the next reader never has to reconstruct the previous meeting.

This is the point that separates this guide from a buying committee map. The committee map tells you who matters. The presentation map tells you where each answer lives and what evidence can travel with it.

Each reader searches, and stops at the first gap

A functional reader uses the presentation as a reference. They find their own section, read it closely and skip the rest. If the answer is missing, or sits where they did not look, they record a question, an exception or a no.

The Belief Gap calls the first point where a decision stops being defensible the First Break, and finds it by reading the material in the order the decision-maker meets it. A buyer presentation has five reading orders, one for each function, and each can break on a different page.

Take a supplier that sends a 30-page presentation for a five-year supply agreement. Pages 1 to 12 explain the technology and the mission. The price per tonne appears on page 19. Delivery risk sits in two bullets on page 24. Finance finds a unit price with no total, no schedule and no comparison, and asks for a call. Legal finds "guaranteed performance" on page 6 and flags it. Sustainability finds an impact figure with no method beside it. All three may still like the proposition. Each has stopped at a gap, and the sponsor now carries three open questions into the next meeting.

What each reader needs to find

Use this table as a worksheet. Add the page where your current presentation answers each reader and the source that reader can open if they challenge the claim. Write "missing" where either one is absent.

Reader	Their question	What they need to find	What stops them
Procurement	Can we buy this from this supplier, on terms we can compare?	The supplier and its standing, delivery record and capacity, the offer in comparable units (volume, term, price basis, delivery schedule), how this route compares with other ways to buy, the qualification documents	A price with no unit or comparison. An offer called flexible with no structure behind it.
Risk and due diligence	What could fail, and who carries it?	Each delivery, performance, counterparty and reputational risk by name, the safeguard for each, what happens if delivery falls short, independent verification and its date	A risk page that lists only mitigations. "Low risk" with no basis.
Finance	What is the total commitment, from whose budget, and when does cash move?	Total value over the term, a payment schedule tied to delivery, the comparison the budget owner will use, what changes if volume or price moves	A unit price with no total. Prepayment with no link to delivery.
Legal	What would we be bound to, and what may we say?	The form of commitment (letter of intent, reservation or binding agreement), its conditions, exit and termination, who owns the output, liability if delivery fails, the public statements the buyer may make	Sales wording that reads as a warranty, such as "guaranteed" or "permanent", with no defined terms.
Sustainability	What can we claim, and does it count towards our target?	The standard or method behind each impact figure, delivery dates set against the buyer's target years, the exact claim wording the buyer may use, the limits of the evidence	An impact claim broader than its evidence. Delivery that lands after the target year.

The table is a starting set. Ask the sponsor which functions review this category of purchase, in what order, and which of them can stop it. The buying committee map places those roles around the first commitment. Use this table once the map tells you who will open the file.

Build one core and give each reader a door

The Belief Gap warns against writing a new version of the case for every audience. Its answer is one house, many doors, one full account with each version cut from it. In a buyer presentation the house is a short core every reader shares. The doors are sections each function can find without reading the rest.

Write the core first, in five lines.

1. The decision in one sentence, with its owner and date. For an illustrative supply decision, give the proposed term, annual volume, intended start period, approver and approval date. Use the actual agreed values in a buyer document.
2. What is offered, in the units procurement and finance use.
3. The total commitment and the payment schedule.
4. The status of the evidence, with each claim labelled proven, independently verified, contracted, forecast or still in testing.
5. The first step the buyer can take, and what stays open after it.

Then write the reader sections, and title each one with the question it answers.

Before	After
About us	Who you are buying from, and our delivery record
Our approach to risk	What happens if delivery falls short
Commercial model	What you commit to, and when you pay
Impact	What you can claim, under which standard
Partnership	What you sign first, and what stays open

Put a reader index on page two. "Procurement, pages 4 to 7. Risk, pages 8 to 11. Finance, pages 12 and 13. Legal, page 14. Sustainability, pages 15 and 16." Add a source pointer beside any number or claim that a reader is likely to carry into diligence.

Three rules keep the doors attached to the same house. Keep one approved source for every figure. Repeat its status and assumptions consistently wherever that figure appears, and share confidential pricing only with the authorised readers. Every claim a reader is likely to challenge links to its source, and an evidence register keeps that record. Where the evidence does not yet support a claim, the section says so and names what would strengthen it. Legal and risk can work with a stated limit.

When one presentation becomes a set of short pieces

One document works when the five readers meet the case together. Often they meet it in stages. Evaluators shortlist suppliers first. Diligence follows weeks later and needs depth. The sustainability sponsor writes an internal business case before approval. Procurement, finance and legal meet the terms at the end.

Split the material when the readers arrive at different stages, when one reader needs depth that would bury the others, or when part of it is confidential to a few people. A long-term supply sale often needs four pieces.

• Shortlisting presentation. For the sponsor and evaluators comparing options. The core, the product or project and the delivery record.
• Integrity and risk paper. For risk, technical and procurement teams in diligence. Each risk, its safeguard, the verification behind it and what happens on a shortfall.
• Corporate case. For the sustainability lead or sponsor building the internal business case. How the purchase fits the buyer's targets and what the buyer can claim.
• Offer and terms. For procurement, finance and legal at approval. Volume, term, price basis, payment, the form of commitment and the exit.

Open each piece with three answers. Who receives it, when, and what they have to decide. Cut every piece from the same core, so the volume, price basis and evidence status match across all four. Write first for the reader whose check opens next, and let the buying committee map tell you which one that is. When the open question is a delivery risk at a first plant, how to present first-of-a-kind risk sets out the risk material.

Run the five-reader test before it goes

Ask five colleagues to read as one function each. Give each person their question from the table and five minutes to test whether they can find the answer. This is a navigation check. A full technical, financial or legal review still needs the responsible specialists.

1. Each tester writes the page where they found their answer, or "not found".
2. Each tester writes the first sentence that would make them send a question back.
3. Compare every figure the five testers used. Any number that differs between sections gets fixed before sending.
4. Check each sentence legal or risk flagged against its source and its evidence label.
5. Ask the sponsor which function is most likely to stop the purchase, and rewrite that reader's section first.

Record the result as a map, not a score. The page a tester cannot find, the source they cannot open and the sentence that creates a new question each become an edit before the file goes out.

Sometimes all five readers find their answers and the purchase still stalls. Then the cause may sit outside the document. Check the six gates in The Belief Gap. They are evidence, economics, incentives, authority, capacity and timing, and regulation. A budget nobody has allocated, a supplier that fails qualification or a claim the rules do not allow each needs its own work. When Better Communication Is the Wrong Answer works through each check.

A buyer presentation has done its job when each of the five functions can find its answer, check the source and pass the decision on to the next.

Brighter Future builds buyer presentations and the short pieces behind them, from the map of who reads them to finished, designed documents, through our Buyer & Commercial Cases. Each piece starts from who receives it, when and what they have to decide, and you approve every technical, legal and commercial claim before it goes out. When a purchase has stalled and the cause is unclear, The Belief Diagnosis finds where the case first stops.
