The Pilot Worked. What Belongs in the Commercial Proposal?

A pilot presentation pasted into a price quotation leaves most of the work undone. The proposal has to show that this particular commitment fits the evidence the pilot produced, and that this organisation can approve it.

Two documents leave the supplier's side after a pilot, and they do different jobs. The buyer's champion circulates the one-page internal approval case, written in the buyer's language for the people who authorise the purchase. The commercial proposal is the document procurement, legal and operations work from. It holds the scope, the obligations, the price and the conditions the contract will later record. Write the two from the same facts, so both name the same commitment, price and owner.

Open with the decision

The first page names the buyer, the commitment requested, the part of the operation involved, the price or pricing basis, the start conditions and the person who must approve it. If the commitment depends on a technical gate, write the gate on that page.

A first line such as “Approve a paid qualification run on the named production line, under the attached test and service conditions” tells procurement what it is buying. It can move through an internal workflow as written. A line about an innovative decarbonisation solution leaves procurement to work out what the purchase is.

Carry the pilot evidence into the scope

One short section covers the trial's objective, the method, the observed results and the limits of those observations. Then mark which results support the commitment in this proposal and which assumptions still need work.

A lab-scale result may support a qualification programme and leave an industrial supply guarantee unsupported. When the proposal says so, the buyer can evaluate the next risk directly, and nobody uncovers a hidden assumption during diligence. The full pilot record, with its agreed success criteria and test conditions, goes in an appendix. Why Successful Climate Tech Pilots Do Not Always Become Purchases sets out what that record should hold.

Write the obligations on both sides

The proposal tells both parties what they must deliver.

Named roles and milestones make the risk legible. A promise to be “hands-on” leaves the reader to guess who does what. If a critical responsibility is still under negotiation, label it an open dependency in the main text, where the reader will meet it.

List the exclusions as plainly as the inclusions. Integration work, additional sites, software changes and out-of-hours support are examples of items to place on one side of the line in writing. Where the deployment carries operating risk for the buyer, the operating risk register supplies the owners for this section.

Make the economics inspectable

Show the price and the commercial unit, what it includes, what the buyer supplies, the assumptions behind any savings or yield figure and how changes will be handled. If a trial price leads to volume pricing, state the trigger and the evidence that sets it off. Give the price and terms a validity date.

Keep forecasts and measured economics on separate lines. The first page can carry the total and still say where the cost model comes from. For industrial processes the buyer will set the price beside the current alternative and the cost of switching, so put that comparison in the proposal before finance builds its own.

Ask for the step the evidence supports

A positive pilot may justify a paid qualification, a phased purchase, a conditional offtake, a supplier onboarding programme or a framework agreement. An unrestricted annual contract is one option among these, and it needs the most evidence. Ask for the commitment the pilot record can carry. From Pilot to Purchase shows how to size the smallest defensible commitment.

Then write what happens if the gate is missed. Name the result that counts as a miss, what each side owes at that point and how either side can stop. The approver can then see the size of the downside before signing.

The proposal, section by section

Test the first page before you send the whole proposal

Ask the buyer's champion to send the first page internally. Then ask someone in procurement or operations what they would need to progress it. If nobody can answer, the open question is who owns the decision, and the buying committee map is the place to start.

When the pilot evidence has to become a proposal that procurement, operations and finance can each read, our science communication work builds proposals and deployment cases from the technical record, with the claim, the evidence and its boundary kept together.

Questions people ask

How should we position a paid demonstration project?

Present it as a defined stage with scope, responsibilities, cost, success criteria, learning objectives and the decision it enables. It should produce evidence both sides can use for that decision. Agree what happens after the test before it starts.

How do we write a joint development proposal that gets signed?

Define the development objective, the intellectual property and data rights, each party's contributions, milestones, acceptance criteria, costs, governance and the commercial option that follows. Ask the legal and technical owners on both sides to validate the terms. The proposal has to make each party's obligations clear, and the long-term vision can sit in the introduction.

How do we turn a letter of intent into a credible next milestone?

Treat the letter as evidence of interest under stated terms. Identify its conditions, its expiry, the validation it requires, any exclusivity and the next contractual decision, then report progress against those conditions. A letter whose limits both sides understand can move the process forward.
