Lox And Chain — Theme migration on Shopify Plus
Shopify Plus theme migration with engraving, a fast-cart drawer and zero-downtime relaunch for a fine jewelry brand.

(01)
The Challenge
Lox And Chain wanted to move to a more modern theme without losing any of the customisations that made the site feel like theirs — and without dropping a single sale during a busy commerce window.

(02)
The Solution
Stack
Shopify Plus, Liquid, custom theme, custom cart and engraving features.
Role
Lead theme migration + custom features + ongoing maintenance.
What we did
- 01Migrated the storefront to a new theme while reworking the design and porting every custom feature one-for-one with no regressions.
- 02Rebuilt the cart drawer to be faster and tighter, removing friction between PDP and checkout.
- 03Implemented engraving on relevant PDPs so customers can personalise pieces inline without an app overlay.
- 04Coordinated a relaunch plan that kept traffic served and orders flowing — zero downtime at cutover.
