Pricing in mass retail, From Fair Pricing to Margin-Driven Management
Pricing is based on three principles (costs, perceived value, competition) and four categories of methods: cost-plus, perceived value, competitive alignment, and dynamic pricing. Pricing sets a price; pricing drives a decision.
The right price is not universal: it depends on the price elasticity of each SKU, its role in the product lineup, and the legal framework governing promotions. In retail, it is the margin achieved—by SKU and by region—that determines a price, not the listed price.
Pricing is the process of setting, adjusting, and managing a product’s selling price by combining three factors: cost of goods sold, perceived customer value, and competitors’ prices.
It is an ongoing decision, the result of which is reflected in the actual margin rather than in the listed price.
This guide reviews pricing methods, the difference between pricing and fair price, and the specific challenges faced by the retail industry: the role of product SKUs, legal limits on promotions, and constant price comparisons.
The simulator below shows in just a few seconds how a price change affects volume, revenue, and margin.
Simplified model with constant elasticity, excluding promotions, out-of-stock situations, and cross-effects between products. The default value (-1.5) is for demonstration purposes only; replace it with your measured elasticity.
What Is Pricing? Setting a Price, Driving a Decision
In French, we refer to this as "pricing policy" or "pricing." The English term has become the standard because it refers to the entire process, not just the resulting price.
Broadly speaking, pricing encompasses two aspects: an analytical discipline (measuring customers’ price sensitivity, simulating scenarios, and comparing the market) and an operational practice (setting prices, monitoring them, and adjusting them).
It differs from simply setting a rate in three ways.
It is an ongoing process. A price is adjusted in response to changes in demand, purchase costs, and competitive trends—not just once a year.
It is differentiated. Not all items in an assortment play the same role and therefore do not warrant the same margin level.
It is measured. Without tracking volumes, stockouts, and realized margins, no pricing decision can be validated after the fact.
One principle underlies everything else: the listed price is a business decision, and the resulting profit margin is the outcome.
Confusing the two is the most common mistake, because discounts, off-invoice deductions, and promotions widen the gap between the list price and what the company actually collects.
For short definitions (introductory price, price image, gross margin, back-end margin), the pricing entry in the glossary and the complete pricing glossary bring them all together in one place.
More volatile purchase costs, instant comparisons, and a tougher promotional environment: pricing set just once a year is no longer viable.
Companies improved their 2024 margins primarily through pricing, compared with 38% that did so primarily through volume.
(Simon-Kucher, Global Pricing Study 2025)
Price remains the primary driver of profit margins. However, its effect depends on how demand responds, which is measured by elasticity.
The Four Ways to Set a Price
There isn't just one pricing method—there are four categories. The first three set a price level, while the fourth manages how that price changes over time.
Cost-plus pricing
We start with the cost of goods sold, add a target Markup , and arrive at the selling price. The method is simple, easy to justify internally, and ensures profitability on a per-item basis.
Its limitation lies in what it does not know: what the customer is willing to pay and what the market actually charges.
When applied mechanically, it leaves room for profit on products that are not very price-sensitive and results in a loss of volume on products that are frequently compared.
Value-Based Pricing
The price is determined by what the customer is willing to pay, regardless of the cost. This is the most profitable approach when it can be measured.
It involves testing, willingness-to-pay studies, and detailed customer segmentation, as described by Simon-Kucher.
In retail, the challenge is operational: transforming a concept about value into a framework that can be applied to thousands of SKUs.
Competitor-Based Pricing
We position ourselves relative to market prices: by aligning with them, or by intentionally setting prices below or above them. This method is essential in highly comparable markets, but it assumes that competitors’ prices are known, up-to-date, and comparable in scope.
With a product portfolio of 300 items, no one can keep track of this manually, which is why a well-equipped strategy for monitoring competitor prices is so important.
Dynamic Pricing
Dynamic pricing adjusts prices over time based on demand, market conditions, or available inventory. It ranges from capacity management (yield management) in the transportation and hospitality industries to the daily adjustment of online prices.
In France, the practice of tailoring prices to a customer’s profile is subject to regulations (consumer information, GDPR provisions on profiling): as a result, most retailers adjust their prices by region, sales channel, or store segment—not by individual.
In summary:
| Method | Starting Point | Force | Limit |
|---|---|---|---|
| Surcharge | Cost of Goods Sold + Target Margin | Simple, guaranteed profitability | Ignore the customer and the market |
| Perceived value | Customer's Willingness to Pay | Highest profit margin potential | Complex Measurement and Deployment |
| Competition | Market prices | Price-Image Consistency | Depends on reliable and up-to-date data |
| Dynamics | Demand, Inventory, Context | Responsiveness | Legal framework, detailed management |
Pricing or Tarification: What's the Difference?
The two terms are often used interchangeably, but the distinction is useful. Pricing refers to the act of setting a rate: a rate schedule, a pricing scale, or a suggested retail price. It is generally static and technical.
Pricing encompasses not only the setting of prices but also everything that comes before and after it: understanding perceived value, measuring price elasticity, monitoring competitors’ prices, category-based pricing, and measuring the impact on margins.
In other words, pricing results in a price, while pricing leads to a decision.
| Criterion | Pricing | Pricing |
|---|---|---|
| Subject | Set a price | Determining a price level and managing it |
| Rhythm | On time, for the schedule review | Continuous |
| Data Used | Costs, Fee Schedules | Costs, elasticity, competitors' prices, sales |
| Question asked | What rate should be applied? | What profit margin does this price allow for? |
| Result | A price list | A decision that stands the test of time |
In a retail chain, pricing is often determined by the purchasing department (supplier rates, transfer prices), while pricing strategy is generally the responsibility of the sales and merchandising departments.
The Equilibrium Price and Price Elasticity
The right price is the price that maximizes a product's contribution, taking into account its price sensitivity, its role in the product mix, and the retailer's competitive position.
This is not a universal psychological pricing point: the €9.99 threshold works for certain categories but has no effect on others. The right price is a local optimum, and it shifts.
To understand this, the key concept isprice elasticity: the percentage change in volume resulting from a 1% change in price.
A benchmark with an elasticity between 0 and -1 is price-elastic: revenue increases even if volumes decline. Below -1, a price increase causes revenue to decline.
The published average price elasticities vary widely depending on the scope (a retailer's food products or an entire market), the time period, and the measurement method.
An average doesn't tell you anything: it's the elasticity of each product, measured based on its own sales, that matters.
The calculations, thresholds, and methodological pitfalls (promotions, discontinuations, net prices) are detailed in our article on price elasticity.
A simple calculation changes the way we view a price reduction. Let's take a product sold with a 25% gross margin (for illustrative purposes).
Lowering the price by 5% reduces the unit margin from 25% to 20% of the original price. To maintain the same margin in euros, sales volume must increase by 25%: an elasticity of approximately -5.
Conversely, a 2% increase remains profitable as long as volume does not decline by more than about 7%, corresponding to an elasticity of -3.7.
Our belief is that in the mass retail sector, where margins are tight, a price reduction is almost never offset solely by the volume of that product. It is justified by the price image it creates or by the foot traffic it generates—and these factors can be measured.
The simulator at the top of the page lets you redo this calculation using your own numbers and the measured elasticity of your product.
Pricing in Retail and Mass Merchandising
This is where theory meets real-world complexity: tens of thousands of SKUs, stockouts, legally regulated promotions, and a price image that must be maintained on a zone-by-zone basis.
Every reference has a role
An assortment is managed based on roles.
KVI (key value items) are the benchmark products that customers mentally compare across different retailers: their prices send a much stronger signal about price-image than the average price of the product assortment.
Next come destination products, margin products, and complementary products. Applying the same margin rule to all four of these categories would undermine either the price image or profitability.
The Senate's investigative committee on profit margins noted in May 2026 that retailers engage in “margin equalization,” offering loss leaders with very low or even zero margins alongside less comparable products with high margins (Report No. 632).
The Barbotteau Group, which comprises more than 70 companies and brands in the French Caribbean, made this transition from a flat rate to category-based roles without any intermediate steps between Excel and AI.
Before
- A single " Markup " applied to the entire store.
- Pricing managed in Excel.
- A single pricing director up against a competitor with a pricing team of about 10 people.
- Customer comments about prices they consider too high.
After
- One role per category: traffic, revenue, or margin.
- A segmentation from A to E and three optimal metrics (volume, revenue, margin) per role.
- A direct transition from Excel to a hybrid AI (rules and models).
- A 1-point increase in the " Markup " score for the products tested over the course of a quarter.

As long as a single rate applies to the entire store, no model can strike a balance between image and profitability.
A legal framework that limits promotions
The framework established by the Egalim laws was extended and expanded by the Descrozaille Act (Egalim 3, Act of March 30, 2023): as of March 1, 2024, it also covers hygiene, cleaning, and beauty products.
Promotional discounts are capped at 34% of the value for food products (40% for household goods, cosmetics, and personal care products) and at 25% by volume.
These rules, such as the 10% increase in the threshold for selling food at a loss, have been extended through April 15, 2028.
A cap on the value of food promotions, with a 25% cap on volume for fast-moving consumer goods, through April 15, 2028.
(Commercial Code, Descrozaille Act of March 30, 2023)
In practical terms, a promotional campaign is no longer based solely on the desired discount rate; it is calculated based on the margin remaining after the legal cap.
This is the realm of promotional management and the issue of genuine, compliant discounts, which we covered in our article on Black Friday in retail.
A Constant Comparison
Price comparison sites, automated competitor monitoring, and consumer reports make price discrepancies visible within a few hours, not a few weeks.
A retailer that discovers a discrepancy between its advertised price and the actual price during its monthly inventory check finds out too late.
Omnichannel and Scale
The same product is sold in stores, through curbside pickup, and online, with different distribution costs.
A single price across all three channels can erode margins on one channel and damage the price image on another: retail pricing requires channel-specific rules, not a single pricing grid applied across the board.
Managing tens of thousands of SKUs across multiple regions and store formats isn't something you can do in a spreadsheet.
Product line segmentation and customer segmentation thus become the two structural drivers.
The Most Common Pricing Mistakes
The most costly mistakes aren't reflected in the listed price.
In our view, the most costly is the single- Markup . It protects profitability on paper, but it overcharges for the products the customer compares and undercharges for those the customer does not compare.
Next come the tendency to base decisions on list prices rather than actual margins, overly slow monitoring of competitors, and an average margin figure that masks underperforming departments.
They all stem from the same root cause: making decisions without assessing the impact of those decisions on the benchmark, the region, and the time period.
Managing Pricing Based on Margin
Managing by margin means linking each SKU’s role, its price sensitivity, and its market position, and then evaluating each scenario based on the margin it generates—not on the listed price.
The decision is not finalized until the observed effect has been compared to the expected effect, zone by zone.
At the Barbotteau Group, the director of pricing, Mathieu Guimber, first tested this approach on a selection of supermarket products for one to three months before expanding it to the entire supermarket and then to the group’s four retail chains.
Not the lowest price: the right price, plus a little extra margin.
The company used to apply a single " Markup " to the entire store. Now, each category has its own focus: foot traffic, sales, or profit margin. Complaints about prices being too high have disappeared, and competitors are raising their prices.
- Issue
- Rebuilding a tarnished brand image in an insular market where everyone compares prices.
- What Has Changed
- One role per category, a rating scale from A to E, and a three-month trial period before expansion.

This chain (competitive intelligence, sales forecasting, margin management) is the one that Booper's MPSModular Pricing Solution automates for retailers.
The goal: to manage margins by SKU, by region, and by time period.
To choose a tool, our comparison of retail pricing software and the definition of a pricing tool provide the criteria; the guide to calculating the markup lays out the basics of the calculation.
An Expert's Opinion on Three Practical Issues
Three questions for Fabrice Decroo, Director of Consulting at Booper, on topics that frequently come up in meetings with retailers.
Commentary by Fabrice Decroo, Director of Consulting at Booper
What price discrepancy triggers a consumer alert on a KVI?
There is no legal threshold or universal rule.
What triggers the perception of a price difference is the frequency of purchase and the visibility of the price.
For a product purchased every week, even a difference of a few percent can be enough to cast doubt on the price perception. For an occasional purchase, such differences go unnoticed.
Best practice involves setting, for each KVI family, a target range and an alert threshold that must not be exceeded, based on recent data.
How can you isolate the price effect from the promotional effect in a measured elasticity?
In the model, we separate the two: the historical data is reprocessed to distinguish between the regular price and the promotional price, and we add variables for the promotion itself (prominent placement, flyers, time period) and for stockouts.
Price elasticity at the regular price is then calculated excluding promotional periods; the promotional effect is measured separately, relative to expected sales without the promotion. Without this adjustment, price elasticity measured during promotional periods is generally overestimated.
What legal cap under Egalim 3 actually blocked your promotional plans?
In the food sector, it is the volume cap (25%) that poses the greatest constraint on planning: it limits the share of sales for a particular product that can be generated through promotions, regardless of how attractive the promotion may be.
The value cap (34% for food, 40% for hygiene and cleaning products) limits the discount granted on each offer.
Our advice: Create a promotional calendar for the entire year, item by item, and calculate the remaining margin after the cap before approving a promotion.
None of these responses is based on a market average; each is measured within the scope of the retail chain.
At a food retail group in Southeast Asia, the new prices were first rolled out in a few pilot stores, which were compared weekly to control stores.
Price fluctuations are capped, and any increase is reversed when the committee so decides. The sales data analysis was supplemented by a price perception survey of 818 customers in April 2026.
At the Barbotteau Group, each category role has three optimal prices: one for volume, one for revenue, and one for margin. The team first selects the category’s objective, and the price is determined accordingly.

It is this rigorous approach to measurement that makes it possible to justify a pricing decision before the committee.

Frequently Asked Questions About Pricing
Pricing sets a rate: a rate schedule, a pricing scale, or a suggested price. Pricing encompasses rate setting, measuring price elasticity, monitoring the competition, and category-based arbitrage.
The first is static; the second is a continuous decision.
Four pricing models: cost-plus, value-based pricing, competitive pricing, and dynamic pricing, which adjusts prices over time.
This is the price that maximizes a product’s contribution, taking into account its price elasticity, its role in the product lineup, and the retailer’s market position. It is calculated by category and by region, never as an overall average.
Because the actual amount received depends on discounts, off-invoice deductions, and promotions governed by law.
Adjusting prices over time is legal. However, tailoring a price based on a customer’s profile is subject to consumer law (consumer information) and the GDPR.
In practice, retailers set prices by region, channel, or store segment.
By adjusting pricing strategies: aligning KPIs with the market, raising prices where price elasticity is low, and eliminating unjustified discounts.
The stakes are high: according to Simon-Kucher’s 2025 Global Pricing Study, 44% of companies improved their 2024 margins primarily through pricing, compared with 38% through volume.
"Pricing" translates to "pricing policy" or "pricing." In practice, the term refers to the entire process: setting a price, measuring its impact on sales and profit margins, and then adjusting it.
Because when margins are tight, the volume needed to make up the difference is considerable. With a 25% gross margin (for illustrative purposes), a 5% decline requires a 25% increase in volume to maintain the same margin in euros.

An unauthorized seller sells a brand's products outside the distribution network chosen by the brand. In France, price is not a lever: imposing a minimum resale price is prohibited.
The legal measures focus on the distribution channel: selective distribution and off-channel resale, trademark law to combat the gray market and counterfeiting, and obligations for marketplaces under the DSA. All of these require knowing exactly who is selling what, where, and at what price.
Pricing in the foodservice industry is structured in three tiers: foodservice distributors set net prices on a customer-by-customer basis; institutional foodservice adjusts its prices according to a contract clause; and commercial foodservice sets menu prices subject to constraints related to ingredient costs and local competition.
Each level has its own timing mechanism, and the one that passes on price changes most slowly absorbs the difference. For a distributor, profit margins are lost primarily in the time lag between a price increase and its implementation, and in discounts granted once and never adjusted.
Managing toy pricing involves setting a price for each product that is appropriate for the time of year, the product’s lifecycle, and what customers are comparing it to. Specialists generate 64% of their sales from January through October: it’s outside of the Christmas season that profit margins are determined, when prices aren’t simply imposed.
A new brand stands out early on, a classic holds its ground, and a birthday gift is chosen based more on price range than on a discount. Baby products are priced like equipment, based on trust and product line consistency, and post-holiday unsold inventory—which cannot be destroyed—is sorted by individual item.
