A stockout on a Carrefour delivery means that a product ordered is no longer available at the time the preparer is assembling the package. The system then offers a substitution (an item deemed equivalent) or simply removes the product from the order. Both cases change what the customer receives compared to what they chose, and the levers to limit this occur at several stages of the purchasing journey.
Preparation Hours and Restocking of Carrefour Aisles
The most determining factor for the substitution rate remains the moment when the order is prepared, not when it is placed. The aisles of a Carrefour store are restocked overnight and early in the morning. An order prepared during this early morning slot benefits from full shelves.

Conversely, an order prepared in the late afternoon or evening occurs after several hours of shopping in-store. The most demanded items, especially fresh produce and everyday groceries, have already been taken by physical customers. The preparer finds empty spots and triggers substitutions.
To influence this parameter, one should choose an early delivery slot. A slot between 8 AM and 10 AM generally implies preparation very early in the morning. Late-day slots, while convenient, mechanically increase the risk. As detailed in these practical tips on Design en Ville, choosing the time slot is the first filter to activate before any other tips.

Disabling Carrefour Substitutions: Account Settings
By default, Carrefour offers to replace a missing product with an equivalent. This replacement relies on an algorithm that matches similar items by category, brand, or format. The result can be satisfactory (a plain yogurt replaced by the same range in a slightly different pot) or absurd (ground coffee replaced by instant coffee).
The automatic substitution setting can be disabled in the order settings, before validating the cart. Two options coexist depending on the journeys:
- Global deactivation: no product is replaced, missing items are simply removed and refunded.
- Product-by-product deactivation: the customer checks or unchecks the substitution on each line of their cart, allowing them to accept it for basic products and refuse it for specific items.
- Add a preparation comment: for certain categories (fruits, vegetables, butchery), a free text field allows indicating a preference in case of replacement.
Targeted deactivation, line by line, offers the best compromise. It prevents receiving an unsuitable substitute for a specific product while maintaining flexibility for generic items.
Product Categories Most Exposed to Stockouts in Drive and Delivery
Not all items carry the same risk. High-turnover products with a short shelf life account for the majority of stockouts. Understanding this distribution allows for adapting the shopping list.
- Fresh fruits and vegetables: limited stocks, daily restocking, high variability depending on the season and arrivals.
- Promotional dairy products: temporary offers create a spike in demand that restocking does not always keep up with.
- Private label products in small formats: these items have reduced shelf space and sell out faster than big brands.
- Hygiene or cleaning products on catalog promotion: same mechanism as dairy products, with stock calibrated on normal sales forecasts.
Non-promotional shelf-stable products are the least affected. A standard pack of pasta, a regular bottle of oil, or a can outside of a promotional operation remain available in the vast majority of cases.
Flash Promotions and Stockouts: A Direct Link
Short-term promotional operations create a gap between demand and available stock. The forecasting system, even improved by tools like the Carrefour Links Supply platform deployed in recent years, does not always compensate for a sudden influx of orders for a specific item.
Ordering a promotional product on the first day of the offer reduces the risk. Waiting until the last day significantly increases it. If a promotional item is strategic in the order, it is better to prioritize it as soon as the operation opens.
Checking the Carrefour Cart Before Validation: Reflexes to Adopt
The last step before order validation is often a neglected checkpoint. Several concrete actions reduce unpleasant surprises upon receipt.
Checking the availability note on each line of the cart is the first reflex. Carrefour displays a stock indicator at the time of addition, but this can change between filling the cart and validating it. A product added the day before can go out of stock the next morning. Validating the cart as quickly as possible after completing it limits this discrepancy.
Mentally or in a note, planning an alternative for the three or four products most likely to be out of stock also avoids frustration. If a specific brand of Greek yogurt is regularly unavailable, directly adding the second option to the cart (even if one of the two is removed upon receipt) secures the outcome.
One last often-overlooked point: the size of the cart indirectly influences the substitution rate. The more references there are, the higher the probability that at least one will be out of stock. Consolidating purchases into one large weekly order exposes one more than splitting them into two more targeted orders, especially if one focuses on fresh items and the other on dry groceries.
The most effective lever remains the combination of an early slot, targeted deactivation of substitutions, and a cart validated without delay. These three parameters address different causes of stockouts and, together, significantly reduce the discrepancies between the order placed and the delivery received.
