Black Friday is one of the most anticipated retail events of the year, but without careful planning, it can quickly become a complex operational challenge. During peak demand, one of an e-commerce business's biggest enemies isn't the competition—it's stockouts.
Selling a product that is actually out of stock means dealing with refunds, facing negative reviews, and, above all, losing the trust of newly acquired customers. To maximize profits, the success of your marketing campaigns must be backed by efficient order management and logistics.
To understand the scale of the challenge, just look at e-commerce trends in late November. Facing this period without the right infrastructure can put your entire operation under enormous pressure.
In the US alone, Black Friday 2025 online sales reached $11.8 billion, up 9.1% from 2024, while the entire Cyber Week surpassed $44 billion¹.
At warehouse level, however, the real challenge isn't just the percentage growth in sales, but the concentration of orders into just a few days.
Several fulfillment providers estimate that omnichannel sellers should prepare for daily order volumes of between 3 and 10 times their usual levels during the peak days of Black Friday and Cyber Monday. In some segments, spikes can reach between 300% and 500%.
In Europe, parcel volumes during Black Friday week in 2024 increased by more than 90% compared with an average week, putting significant pressure on logistics systems that were not prepared to handle such a concentrated workload.
From an operational perspective, your warehouse needs to be able to increase its picking and packing capacity almost overnight, with minimal room for error.
A failed delivery or an order cancellation due to an out-of-stock item isn't an isolated problem.
According to nShift's “Delivering for shoppers” (2024) study², approximately 87% of consumers will reduce their spending with a brand—or stop buying from it altogether—after a poor delivery experience.
Looking at the Italian market, a SAS survey³ conducted across a European sample found that 1 in 3 Italian consumers would be willing to abandon a brand after just one negative experience. That figure rises to nearly 60% after between 2 and 5 negative experiences.
The message is clear: during Black Friday, every out-of-stock product can have a customer acquisition and retention cost that goes far beyond a single lost sale.
The surge in sales brings a predictable consequence: an increase in returns.
According to the “2025 Retail Returns Landscape” report by NRF and Happy Returns⁴, the average online return rate in the US reached 19.3% in 2025, up from 17.6% in 2024.
Apparel remains one of the hardest-hit categories, accounting for more than 56% of total e-commerce returns. In addition, practices such as bracketing—ordering multiple sizes or colors with the intention of returning most of them—are now used by nearly two-thirds of online shoppers.
Faced with these figures, where should you start when building an infrastructure capable of handling peak demand? The first step, even before stocking the shelves, is to analyze historical data and classify your inventory correctly.
Black Friday preparation begins months in advance by analyzing your e-commerce historical data. Don't rely on gut feelings; data is one of your most powerful tools for anticipating demand.
This analysis allows you to optimize warehouse space and prioritize effectively:
Once volumes have been estimated, the next challenge is logistical: how do you physically organize goods in the warehouse to prepare and dispatch orders as quickly as possible?
During the Black Friday frenzy, warehouse staff can't afford to waste time walking empty aisles looking for products. That's why successful e-commerce brands use ABC analysis, an inventory classification method based on the Pareto Principle, which divides goods into three priority tiers:
These are your "best sellers." They represent only about 20% of your catalog items but generate a massive 80% of your sales.
📦 Strategic advice: These products must never run out of stock and should be physically placed as close to the packing stations as possible to speed up picking.
These account for roughly 30% of your items and generate 15% of your revenue.
📦 Strategic advice: They require constant monitoring and should be placed in the middle aisles.
These make up the majority of your items (about 50%) but contribute to just 5% of sales.
📦 Stretagic advice: Store these in the most remote areas of the warehouse. To prevent them from turning into dead stock, bundle them with Category A products in promotional kits.
Once your merchandise is classified and positioned, you need to mathematically calculate how much emergency stock to keep on hand. Even the most meticulous analysis can't predict every market curveball. That's where your safety net comes in: safety stock.
Safety stock is your buffer against unpredictable buying surges and supplier delays. Relying on random percentages to define it is highly risky; a mathematical approach is essential. The standard formula to calculate safety stock is:
Safety Stock = (Max daily sales × Max lead time) − (Average daily sales × Average lead time)
This calculation gives you enough operational margin to absorb an unexpected sales spike or a delivery delay from your primary supplier, preventing you from leaving customers empty-handed.
If you sell an average of 10 items a day (with supplier delivery taking 5 days), but your estimated maximum peak is 30 items a day (with a delivery time of 8 days), the math is:
(30 × 8) − (10 × 5) = 240 − 50 = 190 units
This means you should always keep 190 extra units in your warehouse as safety stock.
Numbers aside, optimizing your daily procedures is what truly makes the difference on crucial days:
Implementing and managing all these strategies requires time, personnel, and a lot of physical space.
Handling a seasonal peak in-house can demand extra space, resources, and a rapid overhaul of operations. How do you tackle surging orders without overloading your own infrastructure?
