Above GRND Coffee Co — Headless Specialty Commerce

Above GRND is a specialty roastery whose brand is craft and speed — the site had to feel as considered as the coffee and load instantly. We built a headless commerce hub on Shopify with a Next.js storefront, a subscription roasting selector, and an edge-fast cart that keeps a browse-to-buy flow snappy.

A Next.js storefront renders against the Shopify Headless Commerce API, so Shopify owns catalogue, checkout and payments while we own the experience. Cart mutations run through Vercel Edge for low-latency updates worldwide; Tailwind CSS drives the editorial layout. Localized delivery scheduling is layered on top of the commerce primitives.

Headless commerce is a latency game: every cart update is a network round-trip to Shopify, and a specialty brand cannot afford a laggy shop. Keeping cart and subscription flows feeling instant, while respecting Shopify as the source of truth, was the core engineering problem.

• Edge-cached cart updates so add-to-cart and quantity changes feel instant globally.
• A multi-tier subscription bean selector for recurring roasting orders.
• Localized delivery-scheduling matrices layered over the commerce API.
• A Shopify-headless boundary that keeps checkout and payments on Shopify while the experience stays fully custom.
