Price-channel coherence: protecting the margin without destroying the network.
Key distinctions
Three conditions before calculating.
Comparable net price
Compare the total cost for an equivalent offer: discount, delivery, installation, financing, loyalty and return conditions. The headline gap can be misleading.
Valued service
A channel can legitimately charge for advice, availability, installation or credit. The difference must be visible and proportionate to a value genuinely delivered.
Reaction of the network
The partner can reduce assortment, promotion, stock or advice. That response must be built into the calculation rather than treated as a qualitative objection.
Method
Assessing a price differentiation between channels
- 01Normalise the offer
Compare the same reference, content, guarantee, delivery, service and period; create a net price index after all advantages.
- 02Measure the transfers
Estimate new customers, migration from a partner and movement between references; value each transfer with the contribution given up.
- 03Run scenarios for the reaction
Test maintenance, reduced promotion, partial delisting and renegotiation; attach a probability and an impact to each reaction.
- 04Choose the architecture
Prefer packs, services, exclusives or differentiated calendars when strict parity is not sustainable; document the governance rule.
The register of net price gaps and their consequences
Displayed price, discount, service and customer cost are brought together to distinguish a defensible difference from a destructive conflict.
| Channel | Listed | Discount | Service | Customer net | Contribution |
|---|---|---|---|---|---|
| Direct | €89 | €0 | Standard | €89 | €36 |
| Retail | €99 | €0 | Advice + stock | €99 | €25 |
| Marketplace | €99 | −€5 | Fast delivery | €94 | €19 |
A direct advantage of €13,200 almost cancelled by the partner
1,200 sales migrate from retail to direct. The contribution moves from €25 to €36 per unit, that is €13,200 of gain. The partner then reduces promotion, causing a loss of 500 sales that would have produced €25.
Migration gain: 1,200 × (36 − 25) = €13,200. Network loss: 500 × 25 = €12,500. Net gain: €700, before the cost of conflict and the effect on coverage.
Direct under-pricing is not robust. A distinct direct pack or a valued partner service protects total contribution better.
Acceptance conditions
What must be true to act.
- 01
Prices are compared on an equivalent offer and customer cost.
- 02
Migrations are valued with the contribution of the channel given up.
- 03
At least three partner reactions are quantified.
- 04
Every durable difference has a visible justification of value.
Limits
What this analysis does not prove.
- Partner reactions are strategic and hard to estimate precisely.
- Competition and resale price rules must be examined legally.
- Public comparison sites accelerate the perception of inconsistency even across different packs.
