Rose Inc. is a science-based high-performance color and skincare brand founded by British model and businesswoman Rosie Huntington-Whiteley in partnership with biotechnology innovator Amyris. The brand operates as a digital hub for beauty trends, skincare expertise, and wellness content. Rose Inc. needed features to bundle products, offer promotional discounts, and drive higher average order value through strategic cross-selling.
Shopify's native commerce features lacked flexible bundle and discount capabilities that Rose Inc. required to execute its marketing strategy. Third-party app solutions felt clunky and limited.
Shopify did not natively support product bundles. Competing brands offered curated product bundles at promotional prices—Rose Inc. could not replicate this without external apps
Shopify checkout only supports percentage or fixed-amount discounts, not "buy X get Y free" logic that drives high-value promotional campaigns
Shopify storefront API doesn't support pre-checkout promo code entry. Customers couldn't validate codes before checkout, requiring blind faith in discount accuracy
Bundle and discount apps added friction—unstable integrations, performance drag, and ongoing subscription costs without strategic differentiation
We deep-dive into Shopify's Cart API, Storefront API, and checkout limitations. We don't just work around constraints—we find elegant solutions that work within platform guardrails without feeling hacky or fragile.
Our code passes Shopify's update cycles, theme rebuilds, and plugin conflicts. Rose Inc. team hasn't encountered bundle or promo code bugs in 18+ months of production operation.
We understand that bundles and promos drive AOV and customer acquisition cost efficiency. We didn't just build features—we modeled them to align with Rose Inc.'s marketing strategy and brand positioning.
Rose Inc. team owns the bundle catalog and promo code calendar. Our code is documented and modular so their team can modify bundles, adjust pricing, and run seasonal campaigns independently without developer support.
We engineered a custom mini-cart system using Shopify's Cart API that collects promo codes before checkout. The mini-cart communicates with Shopify's promo code verification API to calculate accurate discounts without requiring customers to proceed to the heavy checkout page. The system manually computes discount amounts for code validation, ensuring the mini-cart reflects totals consistent with Shopify's final checkout calculation.
For product bundles, we modeled them as product variants rather than complex backend logic. Administrators create bundles in Shopify admin as variant options—e.g., a "Skincare Starter Bundle" containing serum, moisturizer, and cleanser at 20% off list price. When customers select a bundle variant, they're purchasing a single "bundle" SKU that we map to component products during fulfillment. This approach gives Rose Inc. unlimited flexibility to create, modify, and discontinue bundles without developer involvement.
We optimized the bundle presentation on product pages—clear photography showing all included items, value calculation highlighting savings ("Save $45 when you buy the bundle"), and comparison to buying items individually. Bundle variants appear alongside individual products, giving customers immediate cross-sell opportunities without navigating separate product pages.
Promo codes execute at checkout where Shopify's APIs are fully enabled. Customers enter codes in the checkout page and Shopify applies them correctly. The pre-checkout validation in our custom mini-cart builds trust by letting customers see discount amounts before committing to purchase.
We integrated analytics to track which bundles are purchased together, seasonal promo code redemption patterns, and average order value lift from bundle purchases. Rose Inc. marketing team uses this data to optimize bundle pricing, create seasonal bundles aligned with seasonal skincare campaigns, and forecast promotional revenue impact.
