Dungeons in a Box: Transforming a Legacy E-commerce System into a Modern Subscription Platform

THE CHALLENGE

Managing Risk in a Legacy WooCommerce Environment

The client operated an online store built on WooCommerce, selling subscriptions for physical products. In addition to standard e-commerce functionality, the system featured a custom code responsible for logistics (integrating with the shipping system) and sales data analysis for production planning.

With the conclusion of a Kickstarter campaign, the client needed to introduce a new subscription model. However, implementing this change within the existing legacy infrastructure posed risks to the established system logic.

Our Approach: A Tailored Symfony-Based Solution

To address these risks, we developed a dedicated Symfony-based solution to manage the sales and production logic of the new subscription.

Our approach focused on:

Isolating critical logic
We created a separate module to ensure that the new subscription could be added without impacting the existing system operations.
Seamless integration
The Symfony-based solution was integrated with WooCommerce and the shipping system, securing ongoing operations.
Preserving proven functionality
After implementation and testing, we replicated the core features of the existing subscription model, ensuring a smooth transition for customers.

RESULTS

A Successful Launch with Future Scalability

Risk-free introduction of the new subscription model
The system remained stable, allowing for a smooth rollout without affecting existing operations.

Future-proof architecture
The modular approach enables further system improvements and expansion.

Decoupled WooCommerce dependency
WooCommerce was reduced to front-end functions, making it easier to replace in the future without disrupting logistics and order processing.

Conclusion

The Dungeons in a Box project is an example of how a well-structured architectural approach can modernize a legacy e-commerce system. By isolating the new subscription logic and ensuring seamless integration with existing components, we minimized risk while creating a scalable foundation for continuous evolution and long-term growth.
