Monitor your discount ads: what a pricing tool changes
Reviewing a sale ad involves verifying, prior to publication, its list price, compliance with the no-loss resale threshold, and promotional caps. At the network level, this review can no longer be done manually.
A pricing tool shifts control to the moment the price is set: price history organized by channel, calculated price ranges for each product, and a record of every decision. However, it must natively incorporate French regulations.
A catalog featuring 400 products, available in-store and online, was prepared in ten days. Each discount must be calculated based on the correct reference price, remain above the break-even point, and comply with EGalim limits.
This article is intended for pricing, promotions, and legal teams that need to ensure the compliance of these ads across an entire network.
He explains where non-compliant listings come from, how a pricing tool works, and what to look for when choosing one.
Monitoring Discount Ads: Why Manual Monitoring Is No Longer Enough
Reviewing a discount ad involves verifying, before it is published, that the advertised discount is calculated based on the correct reference price, that the promotional price remains above the break-even point, and that the promotion complies with the promotional limits.
For a flyer listing ten products, an attentive shopper can do this by hand. But for a flyer featuring several hundred items—listed by store and online—every week, that’s no longer realistic.
10% of the establishments inspected received a compliance order or a citation during the DGCCRF’s investigation into price reductions, and one-third of those offering such reductions were found to be in violation.
(DGCCRF, 2024 investigation into consumer information on prices and price reductions, report published on November 24, 2025)
The rules themselves are outlined in our guide to retail price compliance. This article discusses how to monitor them across an entire network.
Where Do Non-Compliant Listings Come From?
In most cases, no one intentionally posted a false discount. The error arises from missing information at the time the transaction is being processed.
The reference price was based on the current price, not on the lowest price over the past 30 days. A price drop that occurred a few days ago on the website was not noticed by the team putting together the store flyer.
The purchase price has changed since the transaction, and the promotional price has fallen below the threshold for selling at a loss. The selected lot structure exceeds the EGalim cap in value.
These cases have one thing in common: the data existed somewhere, but not where the decision was made. The details of each rule can be found in the 30-day reference price rule, the EGalim rule, and the rule regarding resale at a loss.
What a Pricing Tool Changes
A pricing tool doesn't magically make a retailer compliant. It shifts control: from often incomplete post-hoc verification to a rule applied at the time the price is set.
A reliable price history
The reference price is not derived from memory or one-off data points. It requires a dated, “ product by product ” history—channel by channel—that also tracks short-term declines.
With this history, the reference price for each product is known at all times, as is the maximum discount that can be advertised. This is the information that must be displayed when the transaction is created.
Calculated limits for each product
The break-even threshold and promotional caps serve as limits for the pricing engine: a price below the floor or a calculation exceeding the cap is flagged or blocked before publication.
These benchmarks are only useful if the actual purchase price is kept up to date. This is often where the reliability of the system comes into play, as we explain in “Ensuring Data Reliability Before Deploying a Pricing Tool.”
A record of every decision
In the event of an audit, you must be able to demonstrate how a reference price was established and who approved any exceptions. A decision log answers this question without the need for reconstruction.
This traceability is also used internally to understand past decisions. See “Explainability and Auditability of Price Recommendations ” and “Alerts and Validation Workflows.”
| Control | Handmade | Integrated into the pricing tool |
|---|---|---|
| Reference Price | Reviewed based on the daily price or a one-time extraction | Calculated daily, by product and by channel |
| Break-even point | Verified based on the buyer's known purchase price | Recalculated whenever purchasing terms change |
| EGalim Ceilings | Checked once the plan is set up | Verified during the construction phase of the project |
| Proof in the Event of an Inspection | Reconstructed after the fact | Log of Prices and Exemptions |
What to Look for When Choosing a Tool
Many pricing solutions are designed for markets where these rules do not exist. In such cases, compliance with French regulations is addressed, at best, through specific configuration settings that must be maintained.
Before making a decision, ask to see three things based on your own data: the reference price calculated for a product that experienced a temporary price drop, a warning about selling at a loss following a supplier price increase, and a review of a promotional batch against the EGalim cap.
The rest of the selection process is covered in our guide to choosing and implementing a pricing tool and in the essential features of pricing software.
Compliance in Booper MPS
Booper MPS natively supports the three French regulations: the no-loss resale threshold with its 10% markup on food products, the EGalim promotional caps, and the 30-day reference price for discount announcements.
The checks take effect as soon as prices and transactions are set up in the promotions management module. The alert center flags any rules that have not been followed, and the audit log keeps track of any exceptions.

Before publication, we verify three points for each product: the reference price over the last 30 days, compliance with the no-loss resale threshold, and compliance with the EGalim promotional caps.
At the network level, these checks must be performed by the tool that generates prices and transactions, based on historical price data and up-to-date purchasing terms, rather than being reviewed manually after the prospectus has been compiled.
Yes, provided there is a dated price history— product by product , and channel-by-channel—that also records short-term declines.
The software then calculates each day the lowest price over the past 30 days and the actual discount that can be advertised. It can flag temporary price drops that reduce the discount for an upcoming promotion before the campaign is set up.
By treating the threshold as a benchmark calculated by the pricing engine for each product, based on its current actual purchase price.
Each change in price or supplier discount updates the minimum price, plus 10% for food items.
Any price offered below this amount is flagged or blocked before publication. The reliability of this check therefore depends primarily on whether the purchase terms have been updated.
It must be possible to demonstrate how each reference price was established and who approved any exceptions.
A price history organized by date and channel, along with a log of decisions, makes it possible to respond without having to reconstruct the data.
During its 2024 investigation, the DGCCRF inspected nearly 5,300 establishments and 350 sites, and found irregularities at one-third of the establishments offering discounts.
No. Many solutions are designed for markets where there is no break-even point for resale or EGalim caps.
Compliance is addressed there, at best, through specific settings that must be maintained.
Before making a decision, ask to see a reference price based on your data following a temporary price drop, a warning about selling at a loss following a supplier price increase, and a review of a promotional batch.
No. The legal department determines how the rules are interpreted; the system applies them consistently to every price and every transaction.
Issues that require a policy decision—such as prices reserved for cardholders or price differences across channels—must be resolved by a legal expert and then translated into rules. The tool then ensures that this policy is applied consistently and tracked.
Yes. Booper MPS natively supports the “no-loss resale” threshold with its 10% markup on food items, the EGalim promotional caps, and the 30-day reference price for discount offers.
These controls apply starting with the preparation of prices and promotional campaigns. The alert center flags any violations of the rules, and the audit log keeps track of exceptions.
In the toy industry, Black Friday kicks off the Christmas shopping season, which accounts for more than a third of annual sales. With the 30-day rule, its price becomes the benchmark for nearly all December promotions.
The discount applies only to the toys being compared, not to licensed products or this year's new releases. Baby care—a thoughtful purchase driven by the timing of births—calls for moderate discounts.
In the high-tech sector, Black Friday accounts for a major portion of annual sales and takes place two months after the back-to-school product launches. It is intended to clear out the previous generation of products rather than to sell off the new ones at a discount.
Refurbished products set a ceiling on the price of new items, and some prices are rising due to the cost of components. The advertised discount is always calculated based on the lowest price over the past 30 days.
When it comes to home appliances, Black Friday success depends more on the selection of models than on the size of the discounts. An 8% price reduction may require a 50% increase in sales to maintain the same profit margin.
It's best to act quickly on the models that are actually being compared, maintain the prices of exclusive models, focus on delivery, installation, and trade-ins, and prepare the 30-day policy starting in October.
