Customise without breaking the store

Most theme changes happen in one of two places. The theme editor handles settings, sections and blocks, the reusable modules Shopify themes are built from. Anything the editor can't do needs code: Liquid, CSS and JavaScript. Code is where stores break, and Shopify's own help page on editing theme code, as checked on 7 November 2026, explains why.

If your code changes conflict with a theme update, Shopify says all of them are removed in the updated copy. The Timeline view restores one file at a time, it can't recover deleted files, and asset files such as CSS, JavaScript, images and fonts have no Timeline history at all. So a careless edit to a stylesheet on the live theme can't simply be rolled back. You can read more on editing theme code safely.

My process avoids all of that. I duplicate your theme first, build every change on the copy, check it on phone and desktop, and publish only when you've approved it. Your store keeps selling on the original the whole time. A store can hold 20 themes, so I tidy old copies if the library is full. Where I can, I build new features as sections and blocks with settings, so you can move and edit them in the theme editor instead of calling a developer. Every file I touch goes into a change log, which turns the next theme update into a short job. If you work with other developers, the GitHub integration records each change as a commit.

Customisation starts from $150, with a fixed quote in writing after a free review. If the goal of the changes is more sales, Shopify CRO starts from $500, and a full redesign falls under store design and development, which starts from $300.

Signs you need this

  • The theme editor won't let you put things where you want them.
  • A past developer's code edits stopped you updating the theme.
  • You need a feature your theme doesn't have, such as a size guide or a custom product layout.
  • Changes look fine on desktop but break on mobile.
  • You pay for an app that only adds a small design element.

What the service includes

Custom sections and blocks

New sections built in Liquid with their own settings, so you can add, move and edit them in the theme editor like any built-in section.

Product and collection pages

Layout changes, extra product information from metafields, size guides, badges and filters shown the way your products need.

Header, footer and navigation

Mega menus, announcement bars and footer layouts customised to fit your catalogue.

Mobile fixes

Spacing, tap targets, sticky add-to-cart buttons and broken layouts fixed at real phone widths.

Leftover app code

Shopify notes that some apps add theme code that isn't removed when you uninstall them. I find it and clean it out.

Backup and change log

A duplicate of your theme before work starts, and a list of every file changed and why.

Why customise with me

01

Built on a copy, never live

Every change is made on a duplicate theme and tested, so customers never see a half-finished edit.

02

Editable by you afterwards

New features become sections and blocks with settings, so routine changes don't need a developer.

How it works

  1. 1

    Free review and fixed quote

    You send the changes you want. I check your theme and its past edits, then send a fixed quote and timeline in writing.

  2. 2

    Duplicate and build

    I duplicate the live theme and build the changes on the copy, with access through a collaborator account you control.

  3. 3

    You review the copy

    You check the changes on the unpublished copy on your own phone and computer, and ask for adjustments.

  4. 4

    Publish and check

    The copy is published, key pages are checked live, and the old version stays in your library as a fallback.

Is this service right for you

A good fit

  • You like your theme but need it to do more.
  • You want changes you can keep editing yourself in the theme editor.
  • You've been burned by edits that broke the store or blocked theme updates.
  • You want one fixed quote for a defined list of changes.
  • You'd like old app code and past edits tidied up while the work is done.

Not the right fit

  • The change is a setting you can make in the theme editor in minutes. I'll tell you so in the review.
  • You use a vintage theme, which Shopify no longer updates. Moving to a current theme is usually better value.
  • You want a brand-new design from scratch, which is a custom theme project.

    What I appreciated most is that Ashraf didn’t just complete the tasks I asked for — he also shared valuable suggestions to improve the store’s design, performance, and overall user experience. Everything was delivered on time, high-quality, and exactly as I wanted.

Your questions, answered.

What store owners ask before starting this kind of project.

Ask me about your store
How much does Shopify theme customisation cost?

It starts from $150. The exact price depends on how many changes you need and how complex they are. I review your theme for free and send a fixed quote in writing. If the changes are aimed at conversion, my CRO service starts from $500.

Will customising my theme stop me getting theme updates?

Not if it's done carefully. Shopify copies theme editor changes into an updated theme, and keeps code edits if they don't conflict with the update. If they do conflict, they're removed from the updated copy, so my change log lets me reapply them quickly.

Can you customise a theme bought outside the Theme Store?

Yes. Bear in mind that Shopify only offers theme updates for themes installed from the Theme Store, so updates for an outside theme depend on its developer.

Will my store go offline while you work?

No. I work on a duplicate of your theme, and the live store keeps selling until you approve the copy and it's published.

Can I still edit things myself afterwards?

Yes. I build new features as sections and blocks with settings wherever possible, so you can change text, images and order in the theme editor without touching code.

Do I need to give you my password?

No. You give me a 4-digit collaborator request code and approve my access with the permissions you choose. You can remove the access at any time.

Can you fix changes another developer made?

Yes. I compare the current code with the theme's original files to find what was changed, then fix or rebuild it properly and record it in the change log.

Should I customise my theme or get a custom one built?

Customising is usually the cheaper option when your theme's structure suits your products. A custom theme makes sense when it doesn't. I'll recommend one or the other in the free review.
