Understanding the 'Why': Key Drivers Behind Ecommerce Replatforming

1. Only 14% of businesses are satisfied with their current platform

The vast majority of ecommerce operators recognize their platforms are holding them back. This staggering dissatisfaction rate reflects fundamental limitations in legacy systems that compound as businesses scale. Monolithic platforms released between 2003-2006 haven't updated core templating technology in over a decade, creating friction that modern merchants can no longer tolerate. When platforms restrict basic functionality, businesses lose competitive ground to more agile competitors.

2. 27% of ecommerce companies are actively looking to switch platforms

More than a quarter of all ecommerce companies are in active evaluation mode for platform migration. This represents a massive market shift as businesses prioritize growth capabilities over the perceived safety of staying put. The evaluation process signals recognition that current platforms cannot support future business requirements.

3. 35% cite limited scalability as their primary platform frustration

Scalability constraints top the list of platform frustrations, followed by delayed implementations, poor customer support, and poor user experience (all tied at 31%). When platforms cap product variants, restrict checkout customization, or charge punitive transaction fees, growth becomes impossible without migration. These technical limitations translate directly to lost revenue as businesses hit artificial ceilings imposed by their infrastructure.

4. 41% switched platforms primarily to improve customer experience

The customer experience imperative drives migration decisions. Over 40% of recent migrators cited CX improvement as their primary motivation, recognizing that outdated platforms create friction that directly impacts conversion rates and customer lifetime value. Modern consumers expect seamless experiences across devices and channels, standards that legacy platforms struggle to deliver.

5. 38% cited the need for greater customization and flexibility

Equal numbers of merchants migrated specifically for customization capabilities and advanced features like AI-driven recommendations. Platforms that restrict checkout modifications or limit product options force brands into generic experiences that fail to differentiate. The ability to tailor every customer touchpoint has become a competitive necessity rather than a luxury feature.
