Developing Carma required creating a flexible and scalable donation system that accommodated various merchant preferences. Some businesses wanted to fund tree planting themselves, while others preferred customer-funded contributions. The app needed to support multiple donation structures—per product sold, per order, or based on order value—while remaining highly configurable and user-friendly.

Seamless Shopify integration was critical, requiring automated product creation, post-purchase donation extensions, and multi-currency support for global merchants. Additionally, user adoption and engagement were key factors, as many store owners sought sustainability solutions but needed a one-click setup, an intuitive dashboard, and customizable branding options.

To address the need for a flexible and scalable donation system, we built Carma with multiple contribution models, allowing merchants to choose between merchant-funded, customer-funded, or hybrid donation strategies. The app supports tree planting per product, per order, or based on order value, ensuring businesses can align environmental contributions with their sales strategy.

For seamless Shopify integration, we implemented an automated product creation system, enabling merchants to easily add tree-planting options to their store. The app also includes a post-purchase donation extension, allowing customers to contribute after checkout. To support global merchants, we integrated multi-currency support with real-time exchange rate conversion.
