A commodity is something where the buyer does not care which supplier they get, so the only variable is price. Wheat is a commodity. Most things do not start that way and many end up that way, and the process is what commoditization names.

It happens in a sequence that is almost always the same, which is the one genuinely useful thing about it: it is recognizable early, by anyone looking.

The sequence

Someone does something distinctive and earns an unusual margin for it.

Competitors copy the visible parts. Partially, and badly, and still enough that a buyer comparing two proposals can no longer tell which is which.

Buyers learn how to compare. This is the decisive step and it is rarely noticed. Once buyers know the right questions, the seller's information advantage is gone, and the questions get standardized — a template, a procurement checklist, a request for proposal.

Price becomes the only remaining variable, because it is the only one that differs.

Margin falls to the cost of the most efficient provider, and everyone less efficient exits.

The sequence can take twenty years or two. What makes it fast now is that the third step — buyers learning to compare — used to require experience and now requires a search.

Recognizing it while there is time

The first symptom is not losing work. It is winning work at a lower price than last year, repeatedly, while explaining each instance. That client was price sensitive. That one was a strategic account. That one was a referral we wanted.

Three other signals, in rough order of appearance: buyers start asking for a proposal template rather than accepting yours; the questions in the first meeting stop being about approach and start being about rate; and competitors you have never heard of start appearing in final rounds.

None of these look like an emergency. That is the problem — commoditization never produces a quarter where something obviously breaks, which is why the response usually begins after pricing power is already gone.

The response that does not work

Cutting price to hold volume. It is the intuitive move and it is competing harder on exactly the dimension that is collapsing. Every round of it trains buyers that the price was negotiable, which makes the next round start lower, which is the discount spiral.

The related failure is cutting cost to protect margin at the lower price. This works for a while and it is a bet that you can be the most efficient provider — which is a real strategy and is only available to one firm in a market. For everyone else it is a slower version of the same exit.

The responses that do

Change what is being compared. If the buyer is comparing day rates, the answer is not a better day rate; it is to stop selling days. A fixed-price outcome, a productized package, a retained relationship with a different unit — all of them break the comparison rather than losing it. See productization.

Go narrower. A commoditizing market usually commoditizes in the middle first. Segments with specific requirements hold their margin longer, because the comparison set is smaller and the buyer's checklist does not fit. This is differentiation used as a retreat, which is a perfectly good use of it.

Change buyer. The same service sold to a different person in the organization is often a different purchase. Sold to procurement it is a commodity by construction, because that is procurement's job. Sold to the person whose problem it solves, it is not.

Accept it and get the scale. Deliberately becoming the efficient provider, competing on cost, and taking the volume. Honest, viable, and a completely different business from the one that was earning a margin on distinctiveness. Worth choosing on purpose rather than arriving at by default.

The one thing that is not available is staying exactly as you are and expecting the margin to return. Commoditization does not reverse on its own.
