The premium is the proof: why B2B buying was never purely rational

I find this one of the most interesting things in business, and one of the least discussed. B2B markets are built on the assumption that buyers decide rationally. The clearest evidence against it is sitting on every invoice: the premium organisations pay, willingly and every day, for partners they believe are worth more.

A rational process, with irrational people inside it

On paper, business buying is the most rational activity on earth. There are tenders, weightings, scoring matrices and a procurement team whose job is to make every decision comparable and defensible. They do that job well. Partners have learnt to play along, which is why pitches fill up with feature tables, capability statements and a day rate that has been shaved three times.

But a scoring matrix is a bit like a bathroom scale. It is very good at measuring the one thing it measures. It has nothing to say about whether you will be glad you chose it in a year's time. The things that can be written down get weighted. The things that can't, such as whether you trust the people in the room, decide the outcome anyway.

The process is rational. The people inside it are doing something more sophisticated.

Why a sensible buyer pays more

Most professional services are bought before they exist. You can't test-drive a strategy, or send a piece of research back because it didn't fit. So buyers do what any sensible person does when they can't inspect the goods. They look for signals: whether the partner understood the brief, whether they listened, and whether the buyer will sleep well the night before the board meeting.

In that situation, paying more can be the most sensible thing to do. Biologists call it a costly signal. A peacock's tail is hopeless for flying and very good at telling everyone the peacock can afford one. A firm that puts senior people on the work, does the thinking properly and has a reputation it would hate to lose is sending the same message. Part of what the premium buys is insurance.

There's an old line that nobody ever got fired for buying IBM. It has lasted because it describes something real. The buyer is choosing for the organisation and, with their name on the paperwork, for themselves.

Four people to please, one decision

A consumer buying a car mostly answers to themselves. A B2B buyer answers to four parties at once: the organisation, which needs the outcome; colleagues, who will live with the partner day to day; customers, who will feel the result; and stakeholders, from the finance director to the board, who will judge the call.

Those four don't want the same thing. The cheapest option can please finance, and frustrate the team. The safest can reassure the board, but leave customers unmoved. There is no single right answer to a sum like that, only a balance, struck by a person under pressure with incomplete information.

Calling that irrational misses the point. It is what good judgement looks like once the spreadsheet runs out.

The premium is the evidence

If you want to know what clients value, the satisfaction survey is a poor guide. Look at what they pay for. Every procurement process has a cheaper option on the table, and buyers regularly look at it, score it fairly and choose someone else. They are paying for something the cheaper option didn't offer, even if it never appears on the evaluation form.

A client who chose you on price will leave you on price. The clients who keep paying more, and defend the decision when someone suggests a cheaper alternative, are telling you something far more useful about your value than any score.

What the premium buys

Our working view, before the data, is that the premium buys four things that rarely appear on an invoice. Confidence that the work will be done well. Protection, in the form of a partner the buyer won't have to apologise for. Ease, meaning less internal effort to get things done. And something less tidy: progress, the sense that this partner makes the client better at what they do.

The Quadrangle 7 Sources of Customer Value framework gives that mix a structure. The seven sources are utility, quality, value for money, ease, experience, brand fit and engagement. In B2B, each one gets judged by more than one person. Value for money is weighed by people who will never use the service but will see the invoice. Brand fit becomes a question about whether a partner is right for an organisation like ours, and whether choosing them reflects well on the person who did. Ease is measured in the internal effort a partner saves, or quietly creates.

What this means for partners

Most partners can list their strengths. Far fewer know which of them a client would miss first, and which they would barely notice if they disappeared. The second list is usually longer than anyone would like.

The uncomfortable implication is that competing hard on what gets scored wins work that is easy to lose. The partners clients would hate to lose compete on what is hard to compare and hard to replace. That often means doing something slightly illogical on purpose: the extra call, the senior person who turns up when they strictly don't need to, the thing nobody put in the brief. Logic is easy to copy. Those moments are much harder.

Do enough of them and something useful happens. When someone inside the client suggests a cheaper alternative, other people argue to keep you, often people you have never met. We call that intentional loyalty: being chosen again, on purpose, by people who could easily go elsewhere.

What we're doing about it

This autumn we've been running a B2B version of the 7 Sources of Customer Value, asking business buyers how they rank the partners they rely on, what they ideally want from them and how well those partners deliver. The question underneath it is a simple one. Every organisation has partners, and a few it would hate to lose. We wanted to know what separates them.

We'll share the findings over the coming weeks, sector by sector where the numbers allow. If you'd like your sector's results first, get in touch.
