Subscription growth: Building the recurring revenue engine

Architecting the auto refill ecosystem to drive a 35% lift in enrollment and a 10% increase in long-term subscriber retention.

Context

Fullscript lacked a structured way to incentivize long-term patient adherence. High-intent patients frequently forgot to reorder, leading to a "leaky" retention funnel where repeat purchases were lost to competitors. I led the end-to-end design for the platform’s first subscription ecosystem, transforming one-time transactions into a predictable "wellness partner" model that significantly increased customer lifetime value.

Challenges

The blank canvas
No framework existed for recurring revenue. I had to map the entire user experience from scratch to ensure the system felt like a helpful support tool rather than a rigid billing commitment.

Cross-functional orchestration
I worked as a strategic partner to the product manager to define the core business logic, collaborating with marketing, account managers, and engineering to build a brand new refill engine.

The incentive paradox
I designed a high-trust communication strategy to help practitioners feel comfortable "opting in" by allocating a portion of their margin toward patient discounts.

Phase 1: Centralizing Order Management

Phase 1:
Incremental Value

I established a dedicated hub for recurring orders. By giving patients total control over their refill dates and quantities, we built the trust necessary to shift from one-time purchases to long-term subscriptions. This removed the friction of "forgotten orders" and kept patients adherent to their treatment plans.

Phase 2: Intent-Based Enrollment

Phase 2: Intent-Based Enrollment

I identified high-traffic "intent points" to drive adoption. By integrating high-incentive subscription prompts directly onto the Product Display Page and within the checkout flow, we made enrollment a natural part of the purchasing journey rather than an afterthought.

"For a subscription model to scale in a health context, it cannot feel like a trap. I prioritized extreme user autonomy by making it as easy to skip or cancel a refill as it was to join. By lowering the perceived risk of enrollment, we did more than just drive conversion. We built the long term trust required to sustain a recurring revenue engine."

Phase 3: The Practitioner Value Exchange

The diagram tracks the inheritance flow from Global tokens (hex codes and raw values) to Semantic tokens (purpose-based logic like 'colour/shade/light/700'), and finally to Component-specific tokens. It highlights specific mappings for padding, corner radius, height, and typography to demonstrate 1:1 parity between design and code.

I designed the opt-in experience for practitioners, allowing them to manage their discount margins within their settings. This empowered them to advocate for patient adherence while securing more predictable revenue for their own businesses.

Conclusion

This project was a case study in balancing user autonomy with business objectives. By designing for "trust first" and giving users complete control over their recurring orders, we unlocked massive growth without increasing customer support friction. This work demonstrates my ability to take a complex business pivot and translate it into a simple, high-converting experience that serves both patient health and the bottom line.
