Shopify Development with Custom Subscription Logic for One Clear Drop — Zero-Waste E-commerce

About the Project

One Clear Drop is a US-based sustainability startup building home and business appliances that solve the challenge of preparing waste for recycling. The brand’s e-commerce model is built around product subscriptions — a recurring revenue structure that reflects both the nature of the product (consumables that need regular replacement) and the brand’s commitment to long-term customer relationships.

Split Development was hired to build the Shopify store from scratch, based on Figma mockups supplied by the client. The scope went well beyond a standard Shopify build: it required custom subscription logic, a promotional mechanic tied to order count, integration with a third-party collections platform, and an automated consumable replenishment system.

Project Objectives

1. Build a Shopify store from Figma to live

The client came with a complete design in Figma. Split Development’s role was to translate that into a fully functional, responsive Shopify storefront — while also making improvements and adjustments based on testing, best practices, and their own technical recommendations.

2. Implement a product leasing and subscription system

The core of One Clear Drop’s business model is a leasing-style subscription: customers pay an initial deposit, then a monthly subscription fee for as long as they use the product. The system needed to handle multiple pricing tiers and conditions — different rates for different products — with the underlying logic: pay upfront, subscribe monthly, until full product value is reached.

3. Build a free-order promotional mechanic

Every third order in a subscription cycle should automatically include a free product. This required custom logic — built through Shopify Flow — to track order count per customer and trigger the promotional delivery at the correct interval without manual intervention.

4. Integrate with a debt collections platform

Subscriptions introduce churn risk. One Clear Drop needed a system to identify customers who had stopped paying — defined as more than three months of missed payments — and pass their data to an external collections platform called Debitura. Split Development built this jointly with Sharpei Subscriptions: an automated pipeline that flags non-paying subscribers and transfers the relevant data, after which Debitura handles either product recovery or payment of the equivalent product value.

5. Automate consumable replenishment

Every three months, replacement cartridges are sent automatically to active subscribers. This recurring fulfilment logic was built as a separate automated flow, distinct from the subscription billing cycle.

Technical Solutions

Sharpei Subscriptions as the subscription engine

Rather than a fully custom subscription build, Split Development integrated with Sharpei Subscriptions — a Shopify-native platform suited to the leasing model One Clear Drop required. The integration handled billing intervals, pricing logic, and subscription state, while custom Shopify Flow logic was layered on top for the promotional mechanics and collections triggers.

Shopify Flow for custom business logic

Shopify Flow was used as the automation layer for both the free-third-order mechanic and the collections pipeline. Flow allows custom business logic to be written directly into Shopify’s infrastructure — no external services, no fragile webhooks. The order-count tracking and Debitura handoff both run through Flow.

Collections system integration with Debitura

The Debitura integration was the most technically complex element of the project. Identifying non-paying subscribers, determining the correct threshold, and formatting and transmitting the data required careful coordination between the Sharpei subscription state and the Shopify order history. Split Development built this jointly with the Sharpei team to ensure the logic was reliable at scale.

Ongoing Support

Split Development continues to support One Clear Drop on a retainer basis — task-by-task support and bug fixes. As a new business, the platform is actively evolving: new functionality is added, edge cases emerge, and the subscription system requires ongoing attention as the customer base grows. All historical metrics are new by definition — the brand launched on this platform.
