From Pilot to Purchase. The Internal Approval Pack

This guide gives the one-page approval case a buyer’s champion can circulate after a pilot. For why successful pilots stall before purchase, read Why Successful Climate Tech Pilots Do Not Always Become Purchases.

A technical pilot can meet its performance targets and still end without a purchase order. The budget owner, the integration, the incumbent it displaces, the risks that remain and the person authorised to decide all sit outside the test.

The document to write next is an internal approval pack. It is one page your buyer's champion can carry into the approval meetings that follow yours. The people who authorise the purchase meet the case on paper, so they decide from what survives in writing.

Decide what is being approved first

Before you write anything, ask your champion three questions.

A paid pilot, a supply agreement, supplier qualification, a first deployment and a full purchase are different commitments, often approved by different people. The budget, the legal exposure, the integration and the supplier onboarding may each sit with someone other than your champion. Press for the open question in the words the approver would use. The wider method for naming a decision is in Start With the Decision.

If the third answer is a missing budget, an uneconomic offer or a regulatory approval still to come, the page waits. The last section of this guide covers that case.

The one-page internal approval case

Use the seven fields below as they stand. Write them with your champion, in the buyer's language, and keep the page to one side of A4. A champion can also fill in the same fields from the buyer's side.

Field	The approver's question	What to write
Decision requested	What exactly must be approved?	The commitment in one sentence, with its scope, the budget requested, the approver and the decision date.
Why now	What changes if the organisation waits?	The buyer's own operating, cost, supply, regulatory or strategic reason to decide now.
Current alternative	What happens if we do nothing?	The incumbent supplier or workaround, what it costs today and where it falls short.
Evidence from the pilot	What did the pilot show?	The success criteria agreed before the test, the result against each, the test conditions and the known limits, each labelled as below.
Deployment plan	Can this be delivered beyond the test?	Integration, resourcing, timings and dependencies, with one owner for each task.
Economics and risk	Can the organisation justify the commitment?	Total cost beside the current alternative in the same unit, the assumptions behind it, the exposure, the mitigations and the risks still open.
Next step and owner	How does approval happen?	The named owner, the approvers, the action each must take and the deadline.

The page is a decision aid that sits beside the procurement paperwork. Any claim that rests on a method, a safety certificate, a financial model or a contract term links to that document, so the champion can send the source without asking you first. Before the page goes, check it against the nine tests in What Your Buyer Has to Defend After You Leave the Room.

Label the proof

Separate four things in the pilot record.

A technically successful trial leaves manufacturing economics, regulatory clearance and performance at full deployment scale still to show. Calling everything validated makes the page shorter and the champion's case weaker. The same split between what a pilot proved and what deployment still has to prove runs through Why Successful Climate Tech Pilots Do Not Always Become Purchases.

Write for the people outside the meeting

The champion sees the opportunity. The other functions meet the liabilities first, and each reads the page from the field it owns.

Write one page for all five. The proposition stays fixed, and each function follows the source link for the field it owns. Brighter Future's Story System applies the same rule to company stories, each written once in depth and then cut for the room.

Ask for the smallest defensible commitment

The first commitment can be smaller than a commercial agreement. Supplier qualification, a funded industrial trial, a reserved allocation or a conditional offtake discussion each give an approver something bounded to authorise. What Is an Offtake Agreement sets out how letters of intent, pilots and purchase agreements sit at different levels of commitment.

Our work with Eeden, a textile recycling company, shows an ask being redesigned. The example comes before a pilot, and the same move applies after one. Eeden's deck for brands explained the technology well and closed on contact details. We built the pitch around the brand's decision. A slide that framed the supply gap as Eeden's opportunity became the brand's risk, because the person signing has to defend the decision to colleagues who never saw the pitch. The close asks for one step, a no-risk Letter of Intent that reserves pilot capacity.

Eeden reports that the pitch helped it sign a major Letter of Intent with a global brand. A Letter of Intent records intent, some way short of a purchase order or a completed sale. How the Eeden pitch was rebuilt sets out the work and the limits of what followed.

The lesson that transfers is the shape of the ask. The case is built around one proportionate commitment that a named person can authorise.

When the problem sits outside the page

Before you treat a stall as a writing problem, check the six conditions The Belief Diagnosis tests ahead of any communication work.

If a gate fails, that becomes the work. A better page leaves missing evidence, a missing budget or a missing permission where it was. When Better Communication Is the Wrong Answer works through each check.

A 20-minute exercise before your next buyer meeting

A pilot has done its commercial job when buyer and supplier agree what the evidence lets them decide next.

When the page is written, the case is credible and the cause of the stall is still unclear, bring Brighter Future the live decision. The Belief Diagnosis finds the First Break, the earliest point where the case stops carrying evidence into a defensible decision, before anyone recommends another deck, website or narrative project.
