In-store pricingmethods, safeguards, and management at scale
Setting a selling price is based on three key factors (costs, demand, and competition), but in retail, the constraints lie elsewhere: a legal price floor (SRP+10 for food products through April 15, 2028), up to 40,000 SKUs in a hypermarket, and an operating profit margin of about 8% for every 1% change in price. Price setting becomes a managed process, with rules and safeguards, rather than an isolated calculation.
If you search for “price fixing” on Google, you’ll come across Wikipedia, BTS courses, and a practice prohibited by competition law. A distributor, on the other hand, faces a much more practical question: at what price should each of its products be listed, and according to what rules?
This guide covers retail pricing: the basic methods, the process that takes a purchase price to a shelf price, legal restrictions, and what changes when you have to set tens of thousands of prices, store by store.
Pricing: Two Approaches, Only One of Which Involves a Distributor
The term encompasses two opposing concepts. For a business, pricing is the process of determining the price of its products. In competition law, it refers to a collusive agreement: market participants who agree to fix or manipulate prices in a market. This guide focuses on the first meaning, without losing sight of the second, as it is the latter that defines the boundaries of the playing field.
The starting point is price freedom, as established by the ordinance of December 1, 1986: a retailer sets its selling price as it sees fit, subject to exceptions provided for by law. Agreements with competitors to fix prices and minimum resale prices imposed by a supplier are subject to penalties (see our article on the suggested retail price and the retailer’s freedom to set prices).
of global revenue excluding taxes: this is the maximum penalty for an illegal cartel, calculated based on the fiscal year with the highest revenue during the relevant period (Commercial Code, Art. L. 464-2).
For a pricing team, the guiding principle is simple: It is both legitimate and necessary to track competitors’ list prices (that is the purpose of price monitoring), but it is never appropriate to discuss upcoming prices with them.
The Three Key Factors for Setting a Selling Price
Textbooks, like search engines, take three different approaches. Each is based on different data, and each has a blind spot.
| Approach | Starting Point | What it protects | His blind spot in retail |
|---|---|---|---|
| By cost | Actual Purchase Price and Target Margin | The unit margin | Ignore what the customer is willing to pay |
| As requested | Perceived Value and Price Sensitivity | Volume and Value Captured | Requires measuring elasticity, reference by reference |
| Through competition | Prices recorded at leading retailers | Pricing Strategy | Sometimes copies a competitor who is himself misinformed |
In retail, you don’t choose a single approach once and for all. The price of a product is determined by combining three factors: a cost-based calculation to establish the minimum price, demand (see price elasticity) to determine how high to set the price, and competition to determine when to follow the market and when to deviate from it.
The weight of each approach depends on the role of the benchmark product in the product lineup, as detailed in our guide to retail pricing policies.
From Purchase Price to Shelf Price
In terms of costs, the basis is not the supplier’s list price but the actual purchase price: the net unit price on the invoice, minus any other financial benefits granted by the seller. These benefits, which retailers refer to as the back-end margin, explain why two items invoiced at the same price do not have the same profitability (see front-end margin, back-end margin).
The pre-tax selling price is then reduced by the target markup rate, and then VAT is applied (all three formulas are detailed in the selling price calculation ). Simplified example (illustrative figures) : a food product purchased for €2.00 net, with a 30% markup rate, sells for €2.00 / (1 - 0.30) = €2.86 excluding VAT, or €3.01 including VAT at 5.5%. The guide to calculating the gross margin details each calculation method.
A legal floor finally sets a limit on the result. Resale at a loss is prohibited, and for food products, the threshold is increased by 10% (the “SRP+10”): the selling price cannot fall below the actual purchase price plus 10%. The full calculation also includes sales tax and shipping costs, so it must be validated by the legal department before being encoded into a pricing rule.
This refers to the increase in the threshold for resale at a loss of food products and pet food, a measure extended through April 15, 2028, by Law No. 2025-337 of April 14, 2025 (Deloitte Avocats).
Setting thousands of prices without using the same method everywhere
A hypermarket can carry up to 40,000 SKUs (FCD). Conducting a comprehensive analysis of costs, demand, and competition for each one is impractical—and would not be advisable: not all of them serve the same purpose.
Product range: This is the total number of products a hypermarket can carry, before multiplying that number by the number of stores, catchment areas, and sales channels (FCD).
Teams that maintain this pricing structure think in terms of product roles. The items that customers instinctively compare (loss leaders, benchmarkproducts) reflect the store’s price image: they are closely aligned with the local market. The back-of-the-shelf items, which receive less scrutiny, are used to rebuild profit margins. End-of-life products follow their own logic ( moving inventory without sacrificing margins).
This approach avoids two common pitfalls: aligning the entire catalog with the competition, or applying the same markup across the board. The results are reflected inthe brand’sprice image and in dedicated pricing KPIs.
Safeguards to Be Included in Pricing Rules
Once the roles have been defined, assigning them is no longer a one-time calculation but rather a set of rules. A few safeguards almost always come into play:
- A minimum threshold per family, below which no recommendation is approved without validation.
- The threshold for selling at a loss is automatically monitored for the relevant products.
- Limited price differences across channels and regions, to maintain consistency without falling into uniformity (see price differences across channels and geopricing).
- Documented exceptions: who granted an exemption, why, and for how long (governance and exemptions).
These rules have an advantage that is rarely highlighted: they make the decision understandable. A price contested by a store or a supplier is justified by the rule that was applied, not by the memory of the person who set it.
Managing Pricing Over the Long Term
This is the increase in operating profit that a 1% price increase generates, assuming constant sales volume, on the average income statement of an S&P 1500 company (McKinsey, *The Power of Pricing*).
This lever works both ways: an incorrectly set price across thousands of SKUs can quickly end up costing more than most management variances. That’s why it’s important to run simulations before implementing changes and then measure the results afterward: actual margin versus expected margin, price variances compared to benchmark retailers, and the percentage of recommendations that were actually implemented.
At Booper, this process is managed through the BOOPER MPS platform: GENIUS Price handles pricing rules, alerts, and simulations, while GENIUS Predict estimates the impact of a price on sales and inventory before it is implemented.

Frequently Asked Questions
Price fixing has two meanings. In a commercial sense, it refers to the process by which a company determines the selling price of its products, based on its costs, demand, and competitor pricing; for a retailer, it's the choice of the price displayed for each item. In a legal sense, the term designates an illegal agreement between competitors to fix or manipulate prices, punishable by fines of up to 10% of global turnover. In a retail context, the first meaning is almost always used, governed by regulations on selling at a loss.
Each retailer is free to set its own in-store prices based on the actual purchase price, a target margin per category, and competitor prices in the area. Loss leaders are priced according to the local market, the core product range accounts for the margin, and the minimum resale price is set legally. Prices can therefore vary from one store to another (see geopricing ).
There are three methods for setting retail prices. The cost-based method starts with the actual purchase price and applies a target margin (see retail price calculation ). The demand-based method starts with the perceived value to the customer and price elasticity. The competitive method starts with prices observed at benchmark retailers. In retail, these methods are combined according to the role of each product: loss leaders are priced in line with the market, core products are priced according to margin, and differentiating products according to perceived value.
Yes, a distributor can freely set its prices: this is the principle of price freedom established by the ordinance of December 1, 1986, now enshrined in the Commercial Code. This freedom has three main limitations. Selling at a loss is prohibited, with a 10% increase in the threshold for food products until April 15, 2028. Price-fixing agreements between competitors are prohibited. And no supplier can impose a minimum resale price. The recommended retail price (MRP) remains a simple guideline, which the distributor may or may not follow.
The resale-below-cost threshold is the price below which it is illegal to resell a product in its current condition. It is calculated based on the actual purchase price: the net unit price shown on the invoice, less any other financial benefits granted by the seller, and plus sales tax and transportation costs. For food products and pet food, this threshold is increased by 10%, a measure extended until April 15, 2028. Exceptions exist, such as sales or perishable goods at risk of rapid spoilage.
To set prices for thousands of items, we approach them by role rather than item by item. Loss leaders, the products customers compare, are priced according to local market rates; core products are priced with margin; and end-of-life products are treated separately through markdowns. These choices are then enshrined in pricing rules with safeguards: minimum margins, minimum resale prices, limited price differences with competitors, and consistency across formats. Finally, we simulate the effect of the changes before implementing them and measure the results afterward, category by category.

The volume sold during a promotion does not indicate whether it created value: part of it comes from similar products (cannibalization), and another part from purchases that were simply brought forward.
Each promotional scenario must be costed out prior to launch using the same metrics: base sales, actual incremental sales, cannibalization, carryover, halo effect, net margin for the category, and cost per unit actually gained.
Margin-volume arbitrage can then be explained: a stated objective, visible forecasting factors, constraints adhered to, and a documented validation process.

Key takeaway: Pricing, promotions, and markdowns are three factors that constantly influence one another, but are still managed using separate tools at most retailers.
This fragmentation creates inconsistencies that are invisible in the short term (a muddled pricing image, margins eroded by promotions that aren’t properly coordinated with markdowns) but costly in the long term. Gartner has, in fact, formalized this convergence as a distinct market category: unified optimization of pricing, promotions, and markdowns.
