Cost-plus feels honest. It is also why hardware startups stay poor.

The fair margin that wasn\'t

I sat with a founder last year while he prepared a quote for a specialty coating line. He opened his spreadsheet, pointed at the bill of materials, added assembly, added thirty percent, and said: I want to be fair. The number came out at ninety-five thousand. The customer\'s alternative was a solvent-based process that cost them roughly half a million a year in permitting, handling and waste fees. He was about to sell half a million euros of annual relief for ninety-five thousand, once, and call the margin fair. We repriced the offer at two hundred and twenty thousand with a payback line in the customer\'s numbers. It closed in six weeks.

Nothing about cost-plus is dishonest. That is exactly the problem. It feels like integrity, so nobody questions it, and it quietly keeps hardware startups poor.

What cost-plus actually does

Strip the feeling away and cost-plus does three mechanical things. First, it caps your price at your bill of materials plus a percentage, which means the value of your engineering flows to the customer for free. A coating that removes half a million of annual cost is priced the same as one that removes nothing, as long as the BOM is identical. Second, it invites procurement into your books. The moment your price is a markup, the negotiation becomes an audit of your components and your percentage. You are now defending your margins instead of discussing their problem. Third, and this is the one that kills companies, it starves the commercial engine. Hardware sales cycles run twelve to twenty-four months with pilots, site visits and qualification files. That work is expensive. A thirty percent BOM margin rarely funds it, so founders underinvest in selling and conclude the market is slow. The market was fine. The price could not carry the sale.

What value-based does instead

Value-based pricing inverts the starting point. You begin with the customer\'s spreadsheet: what the problem costs them per year in downtime, scrap, energy, permits, claims. You price at a fraction of that, commonly a fifth to a third, so the payback fits inside one budget cycle and the decision becomes easy. I have written the full method up separately, with the pump example, so I will not repeat it here. The point for the comparison is what value-based makes possible: a price that funds long sales cycles, a negotiation that stays on the customer\'s arithmetic, and a margin that reflects what your engineering is actually worth to them. It also forces a discipline cost-plus lets you skip: you cannot price from value you cannot articulate, so building the value case early makes your whole commercial story sharper.

The honest comparison

Cost-plus has exactly two legitimate uses. One: commodity products in transparent markets, where the customer can source equivalents and your differentiation is genuinely thin. Two: as a floor. You should know your cost floor cold, because any price below it is subsidizing the customer with your runway. But a floor is not a strategy. In every other case, and deeptech hardware is almost never a commodity, cost-plus is not a pricing model. It is an absence of one, dressed up as fairness.

Why founders cling to it

Three reasons come up every time. Fear of the no: a lower price feels like it reduces the chance of rejection, when in practice price is rarely the real objection in industrial sales. Investor habits: hardware margins make financial models legible, and founders carry the spreadsheet logic into the market. And self-worth: pricing from value requires believing your technology is worth a fraction of a large number, which is emotionally harder than adding thirty percent to an invoice. All three are about the founder\'s situation, not the customer\'s, and that is the tell. Every pricing mistake in this market reduces to pricing from your situation instead of theirs.

How to switch without breaking anything

You do not need to reprice the world on day one. Take your next new prospect and run one value conversation: what does the problem cost you in a bad year, itemized. Build the offer from their number with a payback line, and keep your cost-plus figure only as an internal floor you never mention. If the value case supports two or three times your floor, take it and put the margin into the commercial work the price has to fund. If it does not, that is information too: it usually means the segment is wrong or the value story is unproven, and both are cheaper to learn in a conversation than after a year of thin deals.

Common questions

What is the difference between cost-plus and value-based pricing?

Cost-plus sets the price from your costs plus a margin. Value-based sets it as a fraction of what the problem costs the customer, sized so the payback fits inside one budget cycle. Cost-plus anchors the negotiation on your books; value-based anchors it on theirs.

When is cost-plus pricing acceptable for hardware?

In commodity markets with transparent alternatives, and as an internal floor below which you never sell. For differentiated deeptech hardware it caps your price at your bill of materials and starves the long sales cycle you need to fund.

How do you switch from cost-plus to value-based pricing?

Run one value conversation with your next prospect, itemizing what the problem costs them per year. Build the offer from that number with a payback line, keep your cost-plus figure as a silent floor, and put the extra margin into commercial work.
