Revenue growth at STX after migrating from Adobe Commerce to custom Shopify Plus

STX's revenue is up 200% since launch after Shero moved the brand from Adobe Commerce to Shopify Plus, with an ERP integration, dual-color swatches and a find-a-dealer feature.

40%

Lower maintenance and operating costs at Alto Music

Alto Music moved from Magento to Shopify with custom theme work, checkout and delivery customizations and its Alto Bucks loyalty program carried over. Maintenance and operating costs are 40% lower.

40% faster

Two Shopify stores with a custom credit app

We developed two Shopify stores for Regal Cinemas, Corporate Box Office and Regal Crown Club, plus a custom app for orders paid fully in loyalty credits. Pages load more than 40% faster than they did on Magento.

Shopify Functions

Custom discount and shipping logic in checkout

When an app cannot do what the store needs, we write Shopify Functions for custom discounts, shipping rules and payment options. They work inside Shopify's own checkout, so no extra scripts slow it down.

"Since partnering with Shero Commerce, our eCommerce revenue has grown by 200%. Their support and solutions have been game changers for our business."

James McKenna, Senior Commerce and CX Manager, STX

Why brands work with Shero on custom development

Shero develops to Shopify's API contract, so your custom work keeps working through platform changes.

01

Custom themes designed to perform, not just look different

A custom Shopify theme that looks good but loads slowly costs conversion. Shero develops themes with Core Web Vitals targets set before the first line of code, and performance is measured on real devices at real connection speeds instead of on a developer's local machine.

02

Headless Shopify on Hydrogen for brands that need a fully custom frontend

A headless storefront is the right architecture for brands with complex editorial requirements, multi-market configurations, or performance targets that the standard Liquid theme layer cannot hit. Shero develops Hydrogen storefronts and connects them to Storyblok, Sanity, or Prismic for content management.

03

Shopify Functions for business logic that apps and themes can't handle

Shopify Functions extend Shopify's core logic at the platform level: custom discount logic, custom delivery options, payment customisations, and checkout validations that execute server-side on Shopify's infrastructure. Shero writes Functions for requirements that Shopify's native features don't cover and that third-party apps handle poorly.

04

ERP integrations on Celigo and Patchworks for enterprise Shopify brands

Shopify-to-ERP integrations are one of the most common requirements for Shopify Plus brands scaling beyond basic operations. Shero sets these up via Celigo, which has the deepest set of integration apps for NetSuite, and via Patchworks for brands on other ERP systems.

05

Multi-system automation for enterprise operational workflows

Brands with many connected apps (ERP, CRM, helpdesk, marketing platform, and warehouse) need automation that connects them into coherent operational workflows instead of each system working in isolation. Shero sets up these workflows on tools such as Alloy Automation, which handles complex multi-step processes across the brand's full technology stack.

06

Shopify B2B custom development for manufacturers and distributors

Shopify B2B includes company accounts, catalogs, draft orders, and net terms natively. For B2B operations with more complex pricing logic, approval workflows, or customer-specific catalog requirements, Shero develops custom B2B features using Shopify Functions and the B2B API layer. STX is one example of a Shopify B2B store Shero has delivered.
