Heathen Magento to Shopify Migration

Problem

Heathen is a Warsaw boutique for authenticated designer resale—Acne, The Row, and similar high-AOV pieces. Magento was the stack, and it was leaking sales: category and product pages were too slow for a luxury catalog, images were heavy and unoptimised, variants were unreliable, and cart, checkout, and payment methods kept failing. A high-AOV buyer will not retry a broken Magento checkout. Magento-era load timings were not retained as a published baseline, so we do not invent a before/after seconds claim here.

• Speed—Magento pages were too slow to carry a luxury catalog
• Images—unoptimised assets dragging every product page
• Products and variants—options and inventory were unreliable
• Cart and checkout—the path to pay was breaking orders
• Payments—methods failing or incomplete at checkout

Solution

We migrated Heathen from Magento to Shopify: catalog, variants, and customers onto a new storefront; images rebuilt for the web; cart, checkout, and payments re-wired on Shopify Checkout; then a theme cut for editorial resale—not a Magento leftover.

• Full Magento → Shopify migration (catalog, variants, customers)
• Image pipeline rebuilt so PDPs are no longer carrying oversized assets
• Shopify cart, checkout, and payment methods replacing the Magento failures
• Storefront themed for luxury resale, not a platform default

Outcome metrics

heathen.store is live on Shopify and Magento is retired. The boutique can merchandize authenticated pieces without the Magento speed, variant, and checkout failures that were blocking orders. Client revenue and conversion figures are not published here; the outcomes below mix delivery facts with ShopStack-measured proxies on the live storefront.

Magento to Shopify migration for luxury ecommerce

Heathen is a Magento to Shopify migration for authenticated designer resale in Warsaw. Magento was leaking sales through slow pages, heavy images, unreliable variants, and checkout failures. ShopStack migrated catalog, variants, and customers to Shopify, then rebuilt the purchase path on Shopify Checkout so Magento could be retired.

• Full Magento to Shopify migration (catalog, variants, customers)
• Replatforming a luxury / designer resale boutique off Magento
• Checkout patterns suited to high-AOV orders
• Cutover planned so Magento’s failing path was not left half-alive

Shopify speed, images, and product pages after migration

Migration without performance work just moves the same leaks. Designer-resale photography is heavy; on Magento it dragged every PDP. The Shopify build included an image pipeline suited to web delivery and theme work so collection and product pages could carry a luxury catalog. Live mobile Core Web Vitals for the storefront are published as ShopStack-measured proxies in the outcome metrics above—not as client-reported conversion lift.

• Image optimisation pipeline for luxury product pages
• ShopStack-measured mobile LCP and CLS on the live Shopify store
• Reliable product variants and inventory presentation
• Editorial Shopify theme for resale, not a default theme skin

Shopify cart, checkout, and payments rebuilt

The Magento cart and payment methods were breaking orders. On Shopify, cart, checkout, and payment methods were re-wired so a designer piece can complete as a paid order. For high-AOV ecommerce, checkout reliability is the migration ROI—more than a new homepage hero.

• Shopify Checkout replacing a failing Magento checkout
• Payment methods completed and testable on the new stack
• Purchase path designed for high average order value
