:: Services / Shopify development
A Shopify development company for stores that outgrow their theme
Shopify gets you selling quickly. Growing brands soon need more: a theme that matches the brand, features apps cannot provide, integrations with the rest of the business and pages that stay fast as apps pile up. That is the Shopify work we do.
Custom themes on Online Store 2.0
Custom Shopify apps
Shopify Plus and checkout extensions
:: What we do

New stores, redesigns and the custom work in between.
01
Custom theme development

04

06
Speed and app clean-up
We remove unused apps and scripts, fix Core Web Vitals and replace heavy apps with lighter custom code.
:: Cost and timeline

Typical prices for our Shopify work, based on senior Shopify developers at $25 to $35 an hour. Shopify plans and app subscriptions are separate.

A premium theme adapted to your brand, with custom sections, product page changes and speed fixes.

3 to 6 months
Shopify Plus checkout extensions, B2B trade features, several markets, or a Hydrogen headless storefront.
What it costs to run
Your Shopify plan, paid apps and payment fees. Many stores pay more for apps than they need; we review app spend in every project and replace what custom code can do better.
What moves the price
Custom theme versus adapted theme
Number of templates and sections
Apps to build or replace
Markets, languages and currencies
ERP and fulfilment integrations
:: How it works

Week 1

Current store, apps, speed and conversion data reviewed, and priorities agreed.
Weeks 2 to 3
Design
Key templates designed in Figma and approved.
Weeks 3 to 7
Build
Theme, app and integration work on a development store.
Launch
Go live
Theme publish or migration cut-over, checks on real orders and a month of support.
:: Shopify migration
Shopify migration checklist
Moving from WooCommerce, Magento or BigCommerce to Shopify is routine if these steps are covered. Most problems come from the ones teams skip.
Cover before you switch
Products, variants, images and metafields mapped
Customers and order history imported
Every old URL redirected to its new Shopify URL
Page titles, descriptions and content kept
Payment, tax and shipping rules tested with real orders
Analytics, pixels and email flows reconnected
What goes wrong in migrations
Product URLs changed with no redirects
Customer passwords expected to carry over
Reviews and ratings left behind
Apps installed for every missing feature
Launch on a busy sales day
:: Shopify vs Shopify Plus
When is Shopify Plus worth it?
Plus costs a lot more each month, so the upgrade should pay for itself. These are the signs that it does, and the signs it does not yet.
Move to Plus when
You need checkout customisation beyond standard settings
B2B buyers need company accounts and price lists
You run several stores or brands
Automation with Shopify Flow would save staff hours
Sales volume makes lower payment fees matter
Stay on standard Shopify when
The standard checkout converts well
One store and one market cover your sales
Apps already cover your B2B needs
Volume is still growing
Your team will not use Plus-only features
:: Why Sterling
What you get

Fewer apps, faster pages

Integrations tested on real orders
Code you own
:: Tools we use
