Shopify store development
Setup configures what Shopify already offers. Development changes what the store can do: a custom section for your homepage, product information pulled from metafields, a template for a specific product type, or behaviour no theme setting provides.
We develop Shopify themes in a way you can keep editing afterwards, so new features appear in the theme editor as sections and blocks rather than as code only a developer can change.

Where setup ends and development begins
Most stores need less custom code than their owners expect. Shopify's admin and a well-chosen theme handle products, collections, checkout, shipping and most page layouts. Development is justified when the store needs something those settings cannot express: a size chart that reads from product data, a comparison table across variants, a bundle builder, or a landing page layout repeated across many campaigns.
A useful test is whether the change would need to be repeated by hand every time you add a product or page. If it would, it is a candidate for development. If it is a one-off arrangement of existing blocks, the theme editor is usually enough and costs nothing to maintain.
Which layer a change belongs in
Putting a change in the right layer decides how easy it is to maintain.
| Layer | Typical changes | Who can edit later |
|---|---|---|
| Admin settings | Payments, shipping, taxes, markets, notifications | Store owner |
| Theme editor | Page layouts, colours, fonts, which sections appear where | Store owner |
| Theme code (Liquid, CSS, JavaScript) | New sections and blocks, templates for specific products, data from metafields | Developer, then owner through new sections |
| Apps | Subscriptions, reviews, complex bundles and other functions outside the theme | App settings, owned by the app provider |
Shopify themes are built from JSON templates that hold sections, and sections that can contain blocks the merchant can add, remove and reorder. Building custom work as sections keeps it editable.
How development work is carried out
Specify
Describe each feature in terms of what a shopper sees and what you need to edit. Agree the products or pages it applies to.
Output: Short specification per feature
Duplicate the theme
Work happens on an unpublished copy of your live theme, so customers never see changes in progress.
Output: Development theme with a preview link
Build sections and data
Create sections, blocks and any metafield definitions the feature reads from, with sensible defaults.
Output: Working feature on the preview
Review on real products
You test the preview with your own products on phone and desktop and note anything that looks wrong.
Output: Agreed list of fixes
Publish and document
Publish the updated theme at a quiet time, keep the previous version as a fallback, and write down how to use each new section.
Output: Live feature and editing notes
Illustrative diagram
- Header section group — shared across pages
- Hero section — heading, text and image settings
- Call-to-action block — link chosen in the editor
- Media block — image or video
- Feature blocks — add, remove or reorder
- Metafield-driven band — fills from product data
- Campaign block — reusable on other pages
Typical development requests
Product information from data
Care instructions, ingredients or specifications stored once per product and shown automatically in a consistent layout.
Template for one product type
Furniture, for example, may need dimensions and delivery notes that clothing products do not.
Reusable campaign sections
A promotional banner or feature grid that marketing staff can add to any page without help.
Performance clean-up
Removing leftover code from uninstalled apps and heavy scripts that slow down pages.
What a sound development handover includes
In the theme
- New sections named clearly in the theme editor
- Default content so empty sections do not break layouts
- No edits to the live theme without a saved previous version
- Comments in code where behaviour is not obvious
For you
- A note per feature: where it appears and how to edit it
- List of metafield definitions created and what each holds
- Known limits, such as theme updates that may need re-applying changes
Questions about Shopify store development
Will custom code stop me updating my theme?
Theme updates can overwrite edited files. Keeping custom work in new, separate sections reduces the conflict, and a written list of changed files makes re-applying anything straightforward.
Can you build a feature instead of using an app?
Sometimes. Display features often work well in the theme. Features that process orders, payments or subscriptions are usually safer in an app built for that purpose.
Do you edit my live theme directly?
No. We work on an unpublished copy with its own preview link and publish only after you have reviewed it.
What are metafields and do I need them?
Metafields store extra information on products, collections or other records, such as materials or dimensions. They are worth using when the same type of information appears on many products.
Can you work on a theme someone else customised?
Yes. We review the existing changes first so new work does not conflict with them, and tell you if earlier work is causing problems.
