05What does a buyer and commercial case include?
A buyer and commercial case turns a buyer’s interest into a commitment their company can approve. Brighter Future builds it one priority segment at a time, as one piece or as a programme of pieces in the order you set.
How we build the case
- Choose
We choose the buyers who matter most with you, starting from three named accounts in one segment whose people make the same first decision.
- Carry
We build the case each person has to carry inside their company, for procurement, finance, legal, sustainability and the board.
- Sign
We make the offer easy to sign, with the commitment, what it reserves and what remains open written on one page.
- Forward
We give the champion material to forward to colleagues who never saw the pitch.
The pieces include a sales and marketing plan, named-account strategy, buyer presentations, offtake and reservation offers, proposals, materials your champion can carry and buyer routes on the website. A first technical evaluation, a pilot and a future-capacity commitment each need a different ask and a different level of supporting material.
Why does a buyer who likes the technology still not sign?
A buyer who likes the technology stalls when the commitment reaches colleagues who never met the founder. A purchase order, an offtake or a reservation creates consequences that procurement, finance, legal and the board have to fund, implement, audit or explain later. The Belief Gap, Brighter Future’s 2026 guide, calls this final crossing Commitment.
Three checks come before more proof. Find who else the commitment reaches. Answer the buyer’s question about who else is in with the commitments that already exist. Then ask whether a smaller, bounded first commitment would let the buyer move now. “I Believe You. I Cannot Sign This.” sets out the method.
How do you write a buyer presentation for a technical B2B sale?
A buyer presentation for a technical B2B sale is a reference file for every function that approves the purchase. In the five-reader model, procurement looks for comparable terms, risk and due diligence for exposures and owners, finance for the total commitment, legal for the obligation and permitted claims, and sustainability for the impact basis. The presentation builds one shared core, gives each reader a section titled with its question and links every challenged claim to its source. The Buyer Presentation Has Five Readers walks through it. A presentation for the first meeting may sit alongside a technical annex, a commercial summary and a brief the internal champion can forward.
The brief comes first. It names one reader, one stage, one decision and one ask, such as a head of sourcing deciding whether to add a materials company to a trial list. It also names the colleague the presentation will be forwarded to and the person who approves each claim. How to Brief a Buyer Presentation for a Technical Sale has the full brief.
How do you get a corporate buyer to sign an offtake agreement for a first plant?
An offtake agreement is a contract in which a buyer commits to purchase future output from a project on defined terms. For a first-of-a-kind plant, it turns expected demand into a document a lender can test. The lender judges it on the buyer, volume, price mechanism, duration, termination rights, credit support and conditions. What Is an Offtake Agreement and Why Does It Matter for FOAK Climate Tech? covers those terms.
A corporate buyer can sign sooner when the first step is bounded. A reservation offer or letter of intent states nine items on one page, from the commitment in one sentence and what is reserved to the conversion, the exits and public use. A line headed “What this changes” sits beside a line headed “What remains open”, and every open item names its owner and closing event. For a trial, that covers the scope, evaluation criteria, responsibilities and review date. Your counsel defines the legal effect before anyone signs, and the company and its advisers negotiate the terms. What a Reservation Offer or Letter of Intent Has to Make Easy to Sign lists all nine.
Inside the buyer, the purchase follows the buyer’s own route. For a carbon removal purchase, the case names the budget owner first, gives procurement and risk a project file, gives finance the total exposure and checks claim wording against the VCMI Claims Code of Practice for legal and communications. How to Build the Internal Case for a Corporate Carbon Removal Purchase follows that route. The status of the commitment stays precise throughout the deck, the proposal and later investor material. When the same offtake also has to carry the raise for the plant, our investor storytelling work keeps one evidence register behind both.
Where does a plan for a first corporate customer start?
A plan for a first corporate customer starts with the offer written down, then one segment whose accounts make the same first decision. Three named accounts make a working set. For each one, the plan maps the route to buy, the people involved, what each needs to believe, the evidence available and the next commitment. Channels follow those account decisions. Movement is measured with the decision signals from Aaron C. Leaman’s The Belief Gap, kept apart from activity measures. Start a Technical B2B Marketing Plan With Three Named Accounts sets it out. Your commercial team owns the relationships and uses what it learns in live conversations to refine the plan. Marketing When Your Market Has Fifty Buyers covers the wider strategy.
After a pilot, the buyer’s champion needs one page to carry into the approval meetings that follow yours. That page labels each pilot result as observed, inferred, unresolved or next proof. From Pilot to Purchase. The Internal Approval Pack has the structure.

Relevant work
For Eeden, which turns textile waste into new raw materials for fibre, after a first engagement on brand strategy, stories and buyer personas, we built the case strategy and narrative behind one buyer presentation to a global fashion brand and wrote the speech. The pitch moved the question from why recycle to why sign now. The signers’ objections became its frequently asked questions, and the close asked for one step, a Letter of Intent on favourable early terms. Eeden has said that Brighter Future’s pitch development work directly contributed to securing a Letter of Intent. We state the result at exactly that level.
For the Ecosystem Restoration Standard, we built a website with separate routes for credit buyers and project developers. For DNAir, which captures DNA from the air, the work included entry offers that give each audience a concrete first use.
Frequently asked questions
Can we start with a single buyer presentation?
Yes. One buyer presentation can be an engagement on its own, as Eeden’s sales pitch was, after an earlier brand engagement. The work can also run as a programme of pieces in the order you set, one priority segment at a time.
Do you negotiate the offtake or the commercial terms?
Your team owns customer relationships, commercial negotiations and account decisions. The company and its advisers negotiate the terms, and counsel defines the legal effect of any reservation offer or letter of intent. We build the case, the offer document and the material each approving function needs.
What if the buyer understands and still cannot commit?
We look at the reason. A commitment may depend on evidence, economics, approval authority, capacity, timing or terms that a presentation cannot change by itself. That reason becomes part of the next-step plan. When it is unclear where the decision stops, start with The Belief Diagnosis.
How do you make sure our claims hold up with a corporate buyer?
At the start we ask for the source, test conditions and approver of each claim, and flag claims that need stronger evidence, attribution or clearer boundaries. Before anything is sent, a pre-send fact check compares the material with the source behind each figure and with the public record, including your website, the company register, old PDFs, partner pages and press. Check Your Own Claims Before the Buyer Does sets out the check.
How does this relate to investor storytelling?
Both use the same method for a different reader. An investor decides whether to back the company. A buyer decides whether their company can take on a supplier, a contract and its risks. Many companies need both, and one evidence register keeps the figures the same in each. Investor storytelling covers the raise.
Where do we start?
We start by reading the current material and the feedback from buyer conversations so far, then agree the first decision the work should support.
