Real-Time Product Updates for a Multi-Brand Retail E-Commerce Platform

The Platform 

A large U.S.-based retail organization operates a multi-brand e-commerce platform serving customers across numerous locations. The platform enables customers to browse products, check availability, and place orders for fulfillment through local stores — making accurate, real-time product data essential.

The Challenge: Stale Data, Real Consequences 

The platform relied on a scheduled batch process to refresh its product catalog. While this ensured consistency, it introduced delays between when product changes occurred and when they were reflected. This created several challenges:

• Inventory and product updates were not immediately visible to customers

• Availability mismatches led to out-of-stock items during fulfillment

• Order substitutions and shorted items occurred at rates that impacted customer satisfaction and fulfillment efficiency

The solution also needed to integrate with existing systems without major disruption, support high volumes of product updates throughout the day, and maintain data consistency across multiple brands and locations.

The Solution: Event-Driven, Built to Scale 

To improve data freshness, the team introduced a real-time update capability alongside the existing system. The solution leveraged a cloud-based, event-driven approach to process product and inventory changes as they occur. Using managed messaging and serverless compute, updates could be handled continuously and applied incrementally. Key aspects of the approach:

• Event-driven ingestion of product and inventory changes

• Scalable, serverless processing to handle fluctuating update volumes

• Incremental updates to avoid reliance on full refresh cycles

• Seamless integration with the existing catalog management process

This approach allowed the platform to improve responsiveness without requiring a full system overhaul.

The Outcomes: Faster Data, Fewer Fulfillment Failures 

The introduction of real-time updates resulted in clear business improvements:

• Reduced time for product and inventory updates from minutes to seconds

• Significant decrease in order substitutions and fulfillment issues

• Improved alignment between displayed availability and actual inventory

• Enhanced customer experience through more accurate product data

These improvements also contributed to more efficient store operations and fewer last-minute order adjustments.

The Takeaway 

Batch processing made sense when real-time was hard. It's not hard anymore. For multi-brand retailers where inventory accuracy directly drives fulfillment outcomes, the cost of stale data  in substitutions, shorted orders, and eroded customer trust compounds quietly until it's impossible to ignore.

But the answer isn't always to tear down what's working. By introducing real-time capabilities alongside the existing system rather than replacing it, the platform improved where it needed to without destabilizing what was already working. That discipline, knowing when to augment versus overhaul, is often the difference between a successful modernization and an expensive one. With the right event-driven architecture, you get real-time and reliable. Not one or the other.
