Buyer power is the force that turns value created into consumer surplus instead of producer profit. It has two components. Leverage asks whether the buyer can punish you. Price sensitivity asks whether the buyer cares enough to use that leverage. Both must be present. Either one alone is survivable.
What gives buyers bargaining power?
Leverage sub-questions:
- Concentration relative to the industry. Are there few buyers, each a large share of your volume? Two OEM customers taking 68% of an auto-component maker's output hold the pen on its margins. B2C industries with millions of anonymous buyers score low on leverage unless an intermediary re-concentrates it. A GDS does that between airlines and travelers, a modern-trade chain between FMCG and shoppers, an app store between developers and users. Always ask who aggregates the demand.
- Standardized product, low switching costs. Can the buyer swap vendors between quarters?
- Credible backward integration. Could the buyer plausibly make it themselves? Retailers' private labels are a standing backward-integration threat that keeps every branded supplier's pricing in check. Automakers bringing battery cells in-house are another case.
Price-sensitivity sub-questions:
- Is your product a big share of the buyer's total cost? Big line items get procurement departments, and trivial ones get waved through. Paint is ~3 to 5% of a construction project's cost, and nobody value-engineers the paint. An airline ticket, on the other hand, is a visible, comparison-shopped spend for a household.
- Is the buyer profitable? Thin-margin buyers must squeeze. Rich ones pay for quality and reliability.
- Does your product affect the buyer's own quality or costs downstream? Inputs that can ruin the buyer's product (a critical API in a drug, avionics) buy pricing power. Inputs that are invisible in the buyer's output don't.

What evidence shows buyer power?
For buyer power, pull these.
| Evidence | Source | What it tells you |
|---|---|---|
| ≥10% customer disclosure (amount + segment; name optional) | segment note: Ind AS 108 / IFRS 8 / ASC 280, identical rule | Concentration, straight from the standard |
| DSO trend vs revenue | receivables note + your M2.05 toolkit | Who finances whom: rising DSO with flat sales = buyers dictating terms |
| Gross margin vs input-cost swings | P&L + commodity indices | Pass-through ability = the live pricing-power test |
| Contractual price-downs, MFN clauses, rebate/discount schedules | MD&A, notes, call transcripts | Institutionalized buyer leverage |
| Buyer's own filings: your line as % of their costs | the buyer's AR/10-K | Price sensitivity from the buyer's side of the table |
As anchors, a buyer power score of 1 is millions of un-aggregated households buying a small-ticket, habit-driven item. A 5 is two OEMs that are profitable only if they squeeze, dual-sourcing by policy, with annual price-downs written into the contract.
