When consumers find a promotion on Black Friday, they hardly imagine that that purchase began to be prepared months before. The perception is that November represents the decisive moment for retail, but the reality is different: companies that achieve the best results usually start their preparation in August.
Black Friday has become a major test of companies' operational maturity. The success of the date depends less on marketing campaigns and much more on the ability to integrate technology, logistics, inventory and critical systems before increased demand puts the entire operation to the test. This anticipation is even more relevant given the growth projections for e-commerce. According to the Brazilian Electronic Commerce Association (ABComm), Brazilian e-commerce is expected to generate R$ 258.4 billion in 2026, consolidating Black Friday as one of the moments of greatest pressure on the entire retail technological infrastructure, and the first challenge begins long before sales: the supply chain.
Most of the products sold during Black Friday are imported, mainly from Asia. Between manufacturing, maritime transport, customs clearance and national distribution, the process can take 60 to 100 days. In a scenario of high global demand, any delay in decision-making significantly reduces stock replenishment capacity. But the impact does not end when the merchandise arrives at the distribution center. Wholesalers, distributors, logistics operators and retailers need to work in synchronization so that the product is available exactly when the consumer decides to buy.
In this process, technology becomes part of the logistics operation. Management systems, barcode traceability, integration between stocks and automation of distribution centers make a difference in the speed with which merchandise travels through the entire chain. The second critical point is the stability of the systems.
Mature companies usually adopt, weeks before Black Friday, a period known as code freeze, in which structural changes are no longer implemented in production environments. The logic is simple: the fewer changes during the period of greatest demand, the lower the risk of unavailability. This means that integrations between ERP, e-commerce platform, payment gateways, tax systems, marketplaces and logistics operators need to be completed, tested and approved in the previous months. Waiting for October or November to complete projects is taking unnecessary risks precisely when any failure could mean thousands of lost orders.
Another frequently neglected aspect is the issuance of tax documents. During peak periods, communication between corporate systems and the Finance Department's environments may suffer from instability. When this happens, many companies need to operate on contingency to keep sales going. The problem is not in the contingency itself, which is part of the operation, but in the fact that many organizations only discover performance limitations when they are already processing thousands of orders simultaneously.
Load tests, volume simulations and validation of integrations should be part of the preparation routine long before the promotional date. Furthermore, August is the ideal time to review automated credit rules, commercial policies, tax parameters, inventory limits and approval flows. In periods of high demand, any inadequate configuration can block legitimate sales or create operational bottlenecks that are difficult to correct in real time.
In other words, there is a mistaken perception that Black Friday is won by companies that offer the biggest discounts. In practice, it is usually won by those who manage to keep the entire operation running when the volume of accesses, orders and transactions multiplies in a few hours. Those who wait for November to prepare, in most cases, have already missed the best opportunity to compete.
