Promotion Management Tool: what he must prove before signing
A promotional management tool is judged by its ability to measure the actual profit margin generated by a promotion—after accounting for cannibalization, deferred purchases, and early purchases—and to forecast that margin before committing to the promotion.
He must also review each transaction against a non-promotional reference price and, before the promotion begins, verify the 30-day reference price, the break-even threshold, and the Egalim price caps.
One campaign follows another, the prospectus is finalized six weeks ahead of schedule, and every review concludes that it was a success. Yet the category’s profit margin isn’t keeping pace.
This article is intended for sales, pricing, and category management teams that are considering implementing a promotion management tool.
It doesn't compare features. It outlines what a tool must demonstrate with your data before you sign off on it, and the questions that reveal this.
Promotion Management Tool: What Is It?
A promotion management tool is software that helps plan, simulate, and measure sales campaigns—including pricing, discounts, time frames, and the scope of retail locations.
His real role isn't to plan a schedule. He needs to report, before and after each promotion, how much profit it generated compared to a period without a promotion.
This issue has a significant impact on the bottom line. In the retail sector, the share of sales generated through promotions has never been higher in the past twenty years.
In 2025, 21.9% of sales of consumer goods were generated through promotions in hypermarkets and supermarkets, a 20-year record.

Every aspect of this poorly managed cost is reflected in the margin. This is also true in B2B distribution, where catalog discounts pile up, and in retail pharmacies for over-the-counter products.
How is this different from a traditional pricing tool?
A pricing tool sets a product's permanent price. A promotions management tool determines a temporary deviation from that price and must assess its impact on related products and in the weeks that follow.
Both decisions pertain to the same product at the same time. Managing them in two different tools results in two different margin figures—which is why we advocate consolidating pricing, promotions, and markdowns into a single tool.
To put this decision in the context of a broader IT initiative, our guide to selecting and implementing a pricing tool provides the general framework.
Why Most Promotional Reviews Overestimate the Benefits
Based on our experience supporting about 50 companies since 2014, we’ve come to believe thata promotional analysis that doesn’t account for cannibalization and deferred purchases almost always overestimates the gain.
The spike in sales during the promotion is immediately apparent. The cost of the promotion elsewhere, for similar products, and in the weeks that followed is not reflected in any standard tracking report.
Gross uplift vs. actual incremental
Gross uplift compares sales of the promoted product to its typical week. Actual incremental sales subtract four effects from this surplus that the dashboard does not show.
First, cannibalization: the promoted product takes sales away from its substitutes on the same shelf. Next, purchase deferral: regular customers bring forward a purchase they would have made anyway.
Advance purchases, or stockpiling, create a sales dip in the following weeks for products that can be stockpiled. Conversely,the halo effect boosts sales of complementary products or drives sales through the traffic it generates.
The statistical mechanism behind these transfers is detailed in our article on cross-elasticity, cannibalization, and the halo effect. We will not repeat the measurement method here.
A blind spot shared by the entire industry
This bias isn't limited to retailers. On the brand side, a recent study shows that decision-makers consider their promotions profitable far more often than they actually measure them to be.
76% of the decision-makers surveyed renew promotions without having assessed their profitability, according to a survey of 250 marketing and research executives in the UK consumer goods sector.
(Kantar and Les Binet for the IPA, survey on the profitability of promotions, October 2026)
The same study notes that 82% of respondents consider their most recent promotion to have been profitable, but that more than 60% of them base this assessment on personal opinion or an incomplete analysis.
The case of fresh produce illustrates this well: a promotion that succeeds in terms of volume can cannibalize sales and drive down prices on the rest of the shelf.
What a Promotions Management Tool Must Demonstrate Based on Your Data
In demonstrations, all the tools show an upward sales curve. What sets them apart is what they can reveal about your sales history, your sales processes, and your points of sale.
| Topic | What a demonstration shows | What the tool must demonstrate |
|---|---|---|
| Incremental | A spike in sales during the promotion | Net surplus, excluding cannibalization and carryover |
| Profitability | Volume or revenue | A margin balance by category, in euros |
| Before the surgery | A promotional calendar | Comparison of Several Scenarios for Sales, Margin, and Inventory |
| After the surgery | A tracking table | A reading compared to a control group |
| Compliance | A generic alert | A freeze on reference prices, resale at a loss, and Egalim price caps |
A net increase, not a promotional volume
It all starts with baseline sales: how much the product would have sold without the promotion. An underestimated baseline makes any promotion appear profitable.
Ask to see how the baseline is constructed, and whether the tool effectively eliminates carryover and carryback. If the answer is based on an average of the previous weeks, the results will look good.
The net profitability of a transaction, in euros of margin
A success rate expressed in terms of volume or revenue is not enough. The only metric that matters is the category's margin compared to a period without promotions.
This total includes the discount granted, any contribution from the supplier, and the cost of each unit actually sold. A department's promotional rate is only meaningful when viewed alongside this total.
A simulation before the mission
Measuring after the fact won't make up for a poor decision. The tool must compare several scenarios before committing to a supplier or printing a flyer.
At Booper, every promotion is simulated before it is launched, taking into account its impact on sales, margins, and inventory. Our article on promotional simulation explains how to build a comparable scenario.
A measurement taken after the fact, compared to a reference value
A simulation is merely a hypothesis until it has been tested against reality. Therefore, an evaluation is needed after the intervention, comparing it to a control group that did not receive the promotion.
For a food retail group in Southeast Asia, the new prices were first implemented in pilot stores and compared to control stores, with results tracked on a weekly basis.
This is the same logic used to measure the incremental impact of a promotion rather than the total volume generated. A tool that does not offer this comparison leaves the assessment up to individual judgment.
Reference prices, selling at a loss, Egalim: Compliance must be verified before the transaction
In France, a profitable promotion can also be an illegal one. Three rules must be checked before the promotion is launched—not after a complaint is filed.
First, let's look at the crossed-out price: the reference price for an advertised discount is the lowest price charged over the previous 30 days. The discrepancies surrounding major sales events are detailed in our article on real Black Friday discounts.
Next, the threshold for selling at a loss: for food items, the 1.10 multiplier applies through April 15, 2028. Any discount that exceeds this threshold must be blocked by the system, not detected at the register.
Finally, the Egalim caps on mass-market products: 34% of the value for food items, 40% for non-food items, and 25% of the volume on promotion.
These checks are built right into Booper. What matters, regardless of the publisher, is that they are performed during the simulation, using your own price history.
Key Questions to Ask a Publisher
A list of features alone isn't enough to distinguish one tool from another. However, a few questions about your data are enough to distinguish a monitoring tool from a decision-making tool.
How does your tool calculate baseline sales? If the baseline does not take into account seasonality, weather, or past promotions, any incremental sales derived from it are unreliable.
What do you exclude from the uplift, and can you demonstrate it product by product ? A publisher that can't quantify cannibalization and carryover is selling a balance sheet, not a metric.
Does your simulation provide a margin balance by category? This figure is what allows you to choose between two approaches—or to decide against a transaction.
What criteria do you use to evaluate the results? Without a control group, stores, or time period, the evaluation remains merely an opinion. The same question applies to the testing phase: see our article on POC pricing.
With a catalog of several thousand items
With a large catalog, the challenge isn't simulating a single transaction, but hundreds at a time during peak periods. The start of the school year and the holidays concentrate these decisions into just a few weeks.
The tool must therefore analyze data by family and by group of retail locations, rather than based on a national average. This is also where promotional pricing strategies come into play, helping to avoid eroding profit margins.
This is the approach behind our AI-powered promotion managementsolution: pre-commitment simulation, net incremental revenue analysis, and regulatory compliance—all within a single tool.

Let's discuss your promotionsFAQ: Promotion Management Tool
It's less about features and more about evidence based on your own data.
A useful tool calculates reliable baseline sales, adjusts for cannibalization and deferred purchases to isolate net incremental sales, and expresses each transaction as a margin balance by category.
It simulates several scenarios before making a commitment, compares the results afterward with a control group, and, before proceeding, checks the 30-day reference price, the break-even point, and the Egalim caps.
The pricing tool sets the permanent price, while the promotions management tool determines a temporary deviation from that price.
The second must also measure effects that the first does not account for: sales taken away from similar products, purchases brought forward that will be missing in the following weeks, and sales gained through the halo effect.
Both decisions pertain to the same product at the same time. Managing them using the same pricing and margin framework prevents a promotion from offsetting a price increase decided the previous week.
Yes, first by stopping the operations that erode profit margins without anyone noticing.
Profits rarely come from more aggressive promotions. They come from better-chosen promotions, appropriately adjusted discount levels, and promoted items that have less of a cannibalizing effect on the rest of the aisle.
Across their overall pricing strategy, clients working with Booper see their margins increase by 0.5 to 3 points within a few months. The key remains the same: measure against a benchmark—don’t just assume.
By comparing the category's margin to what it would have been without the transaction.
The sales volume during the promotion is not sufficient on its own. You must subtract sales attributed to substitutes, purchases that were simply brought forward, and the sales dip in the following weeks, and then add any halo effect.
The result is compared to a reference group, control stores, or a comparable period, and relates to the cost of the discount and any contribution from the supplier.
By anticipating it before the operation rather than realizing it afterward.
Cannibalization is significant when the promoted product has similar substitutes on the same shelf at comparable prices. It can be limited by more carefully selecting the promoted product, the discount level, and the network of retail locations.
A simulation tool calculates this transfer on a scenario-by-scenario basis and provides the gross margin for the entire category, not just for sales of the featured product.
It refers to all the decisions involved in a sales campaign: product, logistics, discounts, time frame, retail locations, and then evaluation.
The complexity stems from indirect effects. A promotion affects sales of related products and sales in subsequent weeks, and these effects do not show up in the sales tracking data for the promoted item.
Added to this are French regulations: a 30-day reference price, a threshold for reselling at a loss, and Egalim price caps on mass-market products.
A tool that analyzes data by product family and by group of retail locations, and simulates hundreds of operations at once.
With a large catalog, peak periods concentrate purchasing decisions into just a few weeks. A case-by-case simulation or a national average elasticity cannot keep up with this pace.
Test the tool on your actual historical data, using one product family and a few stores compared to control groups, before expanding it to the rest of the catalog.
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.
