EE, one of the UK’s largest mobile networks, has reimagined trade-in as a native marketplace capability, embedding it directly into the purchase journey and creating a scalable platform that supports the company’s strategic expansion beyond mobile into technology and gaming.
The move addresses a significant market opportunity: research shows more than half of UK consumers have unused devices at home, yet many have never considered trading them in. As demand for trade-in grows—driven by cost-conscious consumers and sustainability concerns—EE identified a gap in the market for retailers offering seamless integration between new purchases and trade-in value within a single, trusted journey.
By rethinking trade-in infrastructure rather than layering on a standalone service, EE has created a solution that reduces friction for customers while giving the business full visibility into volumes, values, and commissions across its expanding product portfolio.
Marketplace Architecture Enables Rapid Deployment
Rather than building bespoke trade-in infrastructure, EE’s digital product and architecture teams identified a critical insight: trade-in follows the same operational pattern as product returns—device intake, logistics coordination, and value reconciliation.
Working with its marketplace platform provider Marketplacer, EE tested whether existing marketplace and returns workflows could be adapted to support trade-in. A proof of concept validated the approach, enabling the company to manage trade-in catalogues, device intake, and settlement processes without complex, one-off integrations.
Once we realised trade-in could follow the same pattern as returns, everything clicked. It gave us a fast, low-risk path forward and allowed us to move with confidence.

The approach delivered speed and reduced technical risk. What began as a small core team scaled to more than ten squads working in parallel, enabling EE to launch simultaneously across its app and website while maintaining delivery control.
Integrated Experience Supports Category Expansion
The new trade-in capability launched with support for six device categories from day one, creating a consistent end-to-end journey across digital channels. Customers can now receive instant trade-in quotes during checkout, with the value applied directly to their purchase—removing friction from the upgrade decision.
We saw trade-in as a way to make upgrading easier for customers, while supporting our expansion into new tech categories. To do that, we needed a solution that could scale quickly and integrate directly into the customer journey.
– Daniel Boulton, Digital Product Manager, EE
For the business, the integrated model provides operational advantages that standalone trade-in services cannot deliver. EE now has full visibility into trade-in activity across categories, enabling data-driven decisions about inventory, pricing, and customer segments. The marketplace architecture also supports sustainability goals by increasing device refurbishment and responsible recycling while recovering value from unused household technology.
Implications for Retail and Marketplace Sectors
By treating trade-in as a core marketplace function rather than a bolt-on service, EE has created a replicable model that can extend across channels and categories. The company plans to expand into additional device types and bring the experience into assisted retail environments, creating an omnichannel trade-in capability.
The approach demonstrates how retailers can leverage existing platform infrastructure to launch new services faster and with lower risk. Rather than waiting for perfect bespoke solutions, EE’s team identified operational patterns already present in their technology stack and adapted them to new use cases.
For marketplace operators and platform providers, the case illustrates the strategic value of flexible architecture. The same workflows powering returns and third-party seller operations became the foundation for a customer-facing trade-in service—accelerating time to market while maintaining operational control.
Building for Future Growth
With trade-in now live across digital channels and embedded into the core purchase journey, EE has established a foundation aligned with its broader strategy in tech and gaming. The solution’s scalability positions the company to respond quickly as customer expectations evolve and new categories emerge.
The integrated approach also creates opportunities for enhanced loyalty and retention, as customers who trade in devices are already demonstrating upgrade intent and engagement with EE’s expanding product range.
