# A single price for everyone is always suboptimal, willingness to pay varies, so a single price either leaves money on the table or excludes profitable customers

## Claim
A company charging one price across all customers is always leaving money on the table at the high end (high-WTP customers would have paid more) or excluding profitable customers at the low end (low-WTP customers who would have been profitable at a lower price). Price differentiation, through fencing, bundling, versioning, or segmented offers, captures more total value by letting each segment pay closer to its actual willingness to pay.

## Mechanism
Willingness to pay (WTP) is heterogeneous across any non-trivial customer base. A single price has to be set somewhere, and wherever it lands, half the buyers would have paid more (lost surplus to the seller) and half find it too expensive (lost volume to the seller). Price differentiation creates a structure that lets the seller capture both: a high-tier offer for high-WTP buyers (premium price, premium components), a mid-tier for the volume segment, and entry tier (smaller offer, lower price) for price-sensitive buyers who would otherwise have walked away. The differentiation must include "fences" that prevent high-WTP buyers from arbitraging into the lower tier.

## Conditions
Holds when:
- Customer WTP genuinely varies across segments (most B2B and considered-purchase B2C).
- The company can construct meaningful tier differences, feature gating, capacity limits, support tiers, audience fencing.
- Cross-segment arbitrage is preventable (the high-WTP buyer can't just buy the low tier).

Fails when:
- Markets with transparent regulated prices (commodities, public utilities) where differentiation is illegal.
- Categories where customer WTP is genuinely homogeneous (some commodity infrastructure).
- The product is too simple for meaningful tier differences.

## Evidence
> "a single price for everyone is always suboptimal because willingness to pay varies across customers, and any company charging one price is either leaving money on the table with high-WTP customers or excluding low-WTP customers who would have been profitable at a lower price."

· see `raw/expert-content/experts/hermann-simon.md` line 17.

## Signals
- Pricing page has 3+ tiers with meaningfully different feature sets, not just feature counts on the same product.
- Segment-level conversion analytics show different price-elasticity curves for different customer segments.
- High-tier conversion rates suggest the high price is right (not too low, otherwise everyone would convert at the top).

## Counter-evidence
Aggressive segmentation can fragment the brand and confuse the buyer; some categories benefit from radical pricing simplicity (Stripe's flat rate, Netflix's small tier count). The discipline is matching segmentation to genuine WTP heterogeneity, not adding tiers because the framework says so.
