B12Rx: Future-Proofing a Growing Health Brand with a Seamless Shopify Migration
B12Rx is a leading provider of B12 injection therapies, serving a growing customer base seeking health and wellness solutions. After years on WooCommerce, the platform had become highly dependent on its founder's deep knowledge of its inner workings—making scale and agility increasingly difficult. Seeking a future-proof solution, B12Rx partnered with Parkfield Commerce to migrate to Shopify Plus, leveraging advanced tools like Klaviyo and modern ecommerce best practices to unlock new growth potential.
B12Rx faced two critical challenges: modernizing their outdated design and reimagining the customer journey. WooCommerce had allowed for a flexible, bespoke shopping experience, but with Shopify’s more structured ecosystem, we needed to rethink how key touchpoints—like product selection and subscription setup—would work. The goal was to not only refresh the visual identity but also to optimize user flows that were originally built on WooCommerce's open-ended architecture, ensuring the new Shopify experience was intuitive, engaging, and high-converting without losing the essence of the original brand.
Leveraging our deep expertise in complex Shopify builds, we designed a smart, streamlined product experience tailored to B12Rx's unique needs. Recognizing that purchasing a supplement like B12 injections isn't as straightforward as adding a T-shirt to a cart, we built a pre-checkout flow on the product page itself. Customers could input critical details like their weight and preferred injection frequency, dynamically feeding into a custom subscription model—all before reaching checkout. Simultaneously, we collaborated closely with the client to evolve their brand aesthetic, delivering a clean, modern design that honored their legacy while positioning them for future growth across both mobile and desktop experiences.

Within just four weeks, B12Rx emerged with a fully reimagined design system and customer journey blueprint, ready to scale on Shopify Plus. The new UX simplified complex purchase decisions and set the stage for higher retention through tailored subscriptions. While Parkfield’s role focused on strategy and design, the feedback was overwhelmingly positive, with the client praising the balance of innovation, usability, and brand alignment. Beyond the handoff, B12Rx is now equipped with a scalable, modern platform designed to reduce operational bottlenecks and drive long-term growth.
