Will we be able to edit the store ourselves after launch?

Yes. We build the storefront from sections and blocks, so each part of a page can be edited in the Shopify theme editor, and we document what every setting does. Swapping a banner, adding a collection row, or reordering homepage sections stays with your team.

Do we need Shopify Plus for a custom theme?

No. Themes are built on Online Store 2.0 sections, which work on any paid plan. Plus matters when you need checkout extensibility, Shopify B2B catalogues, or expansion into several stores at the platform level.

How do you keep a custom theme fast?

We keep the section count on each template sensible, serve images at the size they render, load scripts only on templates that use them, and weigh the theme before blaming the apps. Liquid renders on Shopify's servers, so our levers are markup, assets, and request count.

Can the theme share data with our ERP or CRM?

Through an app, the Admin API, or the Storefront API. Liquid cannot hold custom data or run background jobs, so that logic lives in a small app with its own hosting, and the theme reads the result through metafields or a section rendering call.

Custom Shopify Theme Development

Bespoke Shopify themes in Liquid with section and block architecture, mobile-first product pages, merchant-editable content, and clear platform limits.

A brand with a good product often arrives with a Shopify store that looks like everyone else's. The theme came from a marketplace, the homepage was assembled from whatever sections it shipped with, and product pages carry the same layout as a shop selling phone cases. The catalogue is fine. The buying experience is not, and the team has found that the theme editor only lets them rearrange somebody else's decisions.

Replacing that theme is narrower work than building a store from nothing, because Shopify already runs hosting, checkout, payments, tax tables, and inventory. We design and build the layer a customer touches: the templates, the sections your team edits, the product and collection pages, and the scripts that decide how quickly a page appears.

What the problem usually looks like

Four symptoms turn up in most Shopify projects we take on.

The theme fights the catalogue. Products with variants, bundles, or made-to-order options sit inside templates written for one simple product, so the merchant works around the layout.

Nobody can edit safely. Every change needs a developer, because the previous build put content in hardcoded markup or the editor exposes settings nobody wrote down.

The store got slower each quarter. Apps were installed one at a time, each adding scripts to every page, and the homepage now loads code for features used on two templates.

Checkout expectations are wrong: someone promised a custom checkout design or an extra field, and Shopify does not allow it on this plan.

Who this is for

Direct-to-consumer brands whose storefront no longer matches the product quality. Retailers running a marketplace theme that no longer receives support. Businesses with unusual product structure: configurators, subscription boxes, wholesale price tiers, or a catalogue large enough that filtering and search decide whether anyone finds anything. Merchants with a marketing team who will edit pages daily and need sections that hold their shape.

What we build

Theme architecture

We build on Shopify's Online Store 2.0 structure: JSON templates, sections, blocks, and metafields. Every page is assembled from sections a merchant can reorder, and each section carries blocks so one row of content can be duplicated, rearranged, or removed. That architecture is settled before the first template: which pages exist, which sections each holds, which settings the merchant gets, and which content lives in metafields so the same data appears in several places without being retyped.

Product and collection templates

Product pages carry the sales load, so they get the most attention: image hierarchy, variant selectors that respond to availability, delivery and returns information near the buy box, and structured data search engines read. Collection and search pages get filters shoppers actually use, and pagination that works on a phone.

Merchant controls and handover

We document every theme editor setting, group related controls together, and run a training session with the people who will publish. Where a careless edit could break a section, we change the section so it cannot.

Apps, or code we write

Marketplace apps cover common needs quickly: reviews, subscriptions, loyalty, support chat, shipping rates. They also bill monthly, add scripts to your storefront, and move customer data to another company. When an app is the right call we say so and help configure it. When the requirement is specific to your business, a small private app or a section that does the job itself is cheaper to run. That is the custom plugin and extension work we do for WordPress, WooCommerce, and Shopify.

What Shopify does not let us change

The checkout belongs to Shopify. On standard plans you control the logo, colours, and typography, and app-provided blocks can add limited elements. A checkout with a different layout, extra form fields, or custom steps needs Shopify Plus and checkout extensions. Older stores sometimes carry a checkout.liquid file a previous developer edited; Shopify has retired that approach, so those changes need rebuilding as a checkout extension.

Payments, tax, and shipping calculations are Shopify's. We configure which gateways and carriers you use, and which zones, rates, and tax regions apply. We do not change how Shopify charges a card or computes a tax line.

Hosting and infrastructure are Shopify's as well. There is no server to tune and no database to index, which is much of why the platform holds up under load. Speed work happens in the theme: markup, images, scripts, and request count.

The theme runs Liquid. It cannot store custom data, run scheduled jobs, or call an API in the background. Behaviour that needs memory of its own becomes an app, an Admin API integration, or an external dashboard, the same boundary that shapes B2B portals and dealer dashboards.

Shopify also caps what a template can hold, limiting sections per template and blocks per section, and it sets the rules for the theme store. A page needing twenty sections is a sign it needs restructuring.

The admin interface is fixed: we can add admin blocks through an app, and we cannot rearrange Shopify's screens.

How the engagement runs

Discovery takes a few days: the catalogue, the variants, who edits the site, the installed apps, and the pages that carry revenue.

We design the revenue-carrying templates first, then build in a development store loaded with your real products, so review happens against your catalogue.

Before launch we test on a phone over a slow connection, run through the checkout on the plan you are on, measure Core Web Vitals against the old theme, and confirm every app earns its place. After launch, fixes to custom code follow the bug-fixing policy on the pricing page, and further development runs hourly or under a monthly capacity plan.

What it costs

Our flat rate is $39 per hour, and a custom theme is usually quoted as a fixed scope after discovery. The published typical order for a Shopify store on our pricing page is $2,400 to $4,800 across two to four weeks, covering a storefront configured for immediate sales with original theme design, catalogue setup, payments, shipping, and speed work. A ground-up theme with several custom sections, configurator or subscription logic, or a migration from another platform moves past that range, and monthly capacity plans start at $2,699 for teams with a continuous roadmap.

Scope comes down to templates and sections. Each distinct product type, landing template, and custom section is design and build time, and every app integration is testing time. We tell you which parts can move to a second phase without holding up the launch.

Proof

Sur.co is a premium brand whose Shopify store ran on a template shared by thousands of other shops. We designed and built a bespoke Liquid theme with mobile-first product and collection pages and a purchase flow that stays consistent through Shopify's native checkout, which shows what the theme layer can do for brand and conversion.

TrackVision Tech sells GPS trackers to individuals through a Shopify store and fleet software to businesses through a custom dashboard on the same backend, with monthly and annual plan selection at purchase time. A Shopify theme can carry subscription choices and sit beside a B2B product without splitting into two systems.

A Better Florist was an infrastructure engagement across 114 WordPress and Magento storefronts supported until 2022, mostly on AWS. It shows how much of a storefront's life happens after launch, when hosting stability decides whether orders keep coming in.
