HORIZONTAL INTEGRATION

Definition

Horizontal integration is a growth strategy through which a company expands its business by acquiring or partnering with competitors operating at the same stage of the value chain

In retail, this can take the form of a store chain acquisition, a joint purchasing group, or a commercial alliance

In terms of pricing, horizontal integration offers significant opportunities: greater bargaining power with suppliers, shared resources, and the potential to harmonize pricing strategies.

Why it's important

• Increase bargaining power upstream —with suppliers—which leads to better purchasing terms and, consequently, additional profit margins or more competitive selling prices.
• Pool fixed costs (centralized purchasing, logistics platform, pricing tools) across a broader scope.
• Harmonize pricing practices across integrated entities to avoid conflicting arbitrage opportunities in shared markets.

A concrete example

Two regional home improvement chains, operating 40 and 35 stores, respectively, in non-competing regions, are merging

The resulting entity comprises 75 stores and €480 million in revenue. With its main tool supplier, the new central purchasing organization secured an additional 1.8 percentage points discount on purchasing terms, which is split between a 0.9 percentage point increase in gross margin and 0.9 percentage points reinvested in price reductions on key product categories. The results over 12 months: a 2.1% increase in gross margin and a 4.5% increase in average customer traffic.

How to measure/use it

To take advantage of horizontal integration in pricing, three steps are required: audit current price discrepancies between the merged entities, renegotiate supplier contracts based on the new consolidated market position (often within the first few months), and gradually unify pricing tools to avoid maintaining two systems in parallel

The challenges of change management are significant: the pricing teams of the merged entities must learn to work together and reach joint decisions.

Common Mistakes

• Rushing the harmonization of rates: before fully understanding the specific characteristics of each entity (market positioning, customer base, local competition).
• Underestimating IT complexity: IT system unification can take several years and cause operational friction.
• Ignoring change management: Poorly supported integration leads to the departure of key experts and undermines pricing performance.

Mini FAQ

How long does it take to integrate two pricing models?

Renegotiating supplier contracts can begin in as little as 3 to 6 months

Standardizing tools takes 12 to 24 months, depending on the complexity

Cultural alignment (work styles, metrics) often takes 2 to 3 years.

Should we merge the pricing teams?

Not necessarily all at once. A transitional period during which both teams continue to operate under a shared governance structure helps prevent the loss of local expertise.

What is the risk to the company's image?

There is a real risk that tariff harmonization could lead to noticeable increases in certain areas

Clear communication and a phased convergence schedule help limit the impact, which nevertheless remains a major concern.
