THE SAME-DAY DELIVERY CHALLENGE: WHEN THE WAREHOUSE DECIDES WHETHER TO WIN OR LOSE THE CUSTOMER

A Consumer Who No Longer Accepts Waiting

A few years ago, “fast delivery” meant receiving a package in two or three days. Today, for millions of digital shoppers, that feels slow. The standard set by Amazon, Mercado Libre and major retailers is clear: the order should arrive the same day or, at most, the next day.
According to the 2024 Online Sales Study by AMVO, seven out of ten Mexicans seek to solve their purchases as quickly as possible, and delivery speed ranks among the factors that weigh the most when choosing an online store. Other studies cited by AMVO show that around 76 percent of digital shoppers prioritize delivery speed when deciding where to buy, and that 43 percent abandon their cart when they see delivery times longer than three days.

In this context, same day delivery stops being a “nice to have” and becomes a competitive requirement. The promise of “you receive it today” not only attracts clicks, it builds or destroys customer trust. A delivery fulfilled within hours translates into loyalty and repeat purchases. A delay or failure becomes negative reviews, returns, and a switch to another provider.

The Warehouse Stops Being Storage and Becomes an Immediate Response Center

To enable same day delivery, the warehouse must operate at a completely different speed from traditional logistics. It is no longer enough to store inventory and prepare orders sequentially. It must function as a high-agility fulfillment center capable of processing thousands of orders in very short timeframes.

Every order goes through a critical chain that includes validation, product location, picking, packing, labeling, and route assignment. If any stage stalls, the entire promise of immediate delivery collapses. For that reason, many companies reorganize internal operations with:

• Optimized picking zones to reduce travel time
• Automation and robotics that accelerate order preparation
• Real-time management systems connecting inventory, warehouse, and transportation

During high-demand seasons such as promotions or holidays, the pressure increases. Millions of orders converge within a few days, and the warehouse can become either a bottleneck or the driver of logistics performance depending on how well it is prepared.

Last Mile Delivery: The Most Decisive and Most Expensive Stage

Same day delivery requires a highly efficient last mile, yet it is usually the most complex phase of the entire operation. Traffic, mobility restrictions, hard-to-reach areas, incomplete addresses, and failed delivery attempts significantly increase the cost and difficulty of the process.

The need for speed also causes many routes to lose traditional efficiency. Instead of maximizing a vehicle’s capacity and optimizing distance, what matters is honoring the promised delivery time even if that means dispatching vehicles with lighter loads. To address this challenge, companies rely on:

• Dynamic routing based on real-time traffic conditions
• Live tracking to anticipate delays
• Collaborative networks with motorcycles and electric bicycles in urban areas

This stage defines the customer experience. A well-executed final mile can compensate for any challenge along the way. A poorly executed delivery can ruin the entire shopping experience.

Mexico and Latin America: A Living Lab for Express Deliveries

The accelerated growth of e-commerce in the region has pushed companies to adopt more agile logistics models. Solutions such as in-city micro-fulfillment centers, dark stores exclusively for online orders, and hybrid systems that allow in-store pickup in a matter of hours are becoming more common.

Partnerships with last-mile platforms are also expanding, enabling immediate delivery windows without requiring full internal infrastructure. At the same time, rising market competition pushes retailers to elevate their service level to avoid falling behind growing demand for fast deliveries.

The Price of Speed and the Sustainability Challenge

Offering same day delivery comes with significantly higher costs than traditional models. Distributed inventory, additional personnel, express services, and advanced technology increase operational expenses. Yet many firms view these costs as a strategic investment, since delivery speed increases conversion and strengthens the customer relationship.

In parallel, there is pressure to operate responsibly. More urgent deliveries can mean more emissions and more waste if sustainable practices are not adopted. That is why companies in Mexico and across the region explore electric fleets, cargo bicycles, urban lockers, and recyclable packaging to balance speed with environmental impact.

Speed, Efficiency, and Sustainability: The New Logistics Balance

Same day delivery has become one of the key competencies of modern e-commerce. The ability to deliver an order within hours depends on a highly responsive warehouse, a precise final mile, and a logistics system that balances speed, cost, and environmental responsibility. In a market where the consumer expects immediacy, companies that master this balance will gain a significant advantage. The promise of “you receive it today” is no longer a passing trend. It is the new standard that defines the digital experience and customer loyalty.
