Shopify stores built to sell.

Shopify development starts where the theme editor stops. Shopify gives you hosting, checkout, payments and a solid admin out of the box. What it cannot give you is a storefront shaped around your products, your buyers and the way you actually sell. That is the gap good Shopify development fills: the templates, sections, integrations and data work that turn a generic store into one that earns its traffic.

Unified Marketing has built websites and stores since 2006 for more than 1,100 businesses. We design in a clickable prototype through our website design process, then build with the same no-shortcuts approach as our website development: lean code, only what each page needs, and nothing a future developer would struggle to read.

What Shopify development usually includes

• Custom theme builds or deep customization of an existing theme, written in Liquid, CSS and JavaScript.
• Editable sections and blocks so your team can build landing pages, collection intros and promotions without code.
• Product data structure: variants, metafields, filters and collections that match how customers shop.
• App audits and replacements, swapping heavy apps for theme code where it makes sense.
• Integrations with your CRM, email, reviews, ERP or fulfillment tools.
• Migrations from WooCommerce, Magento, BigCommerce or a hosted builder, with products, customers, orders and redirects.
• Search and feeds: product schema, technical SEO and Google Merchant Center.

Shopify's theme architecture documentation describes how a theme fits together: a layout file wraps every page, JSON templates hold sections, sections hold blocks, and merchants can add, remove and reorder those sections and blocks in the theme editor. Every Shopify development decision comes down to how much of that structure you buy ready-made and how much you build for your catalog.

For most growing brands, the sweet spot for Shopify development is a custom theme or a heavily customized one. You keep Shopify's admin, checkout and hosting, and get product pages, collections and landing pages built around your products instead of a demo store.

What you can and cannot change at checkout

Checkout is the one area where plan level matters. Shopify's checkout settings help says standard checkout customizations, including branding and eligible apps on the thank you and order status pages, are available on the Basic plan or higher. Advanced customization of the information, shipping and payment steps, and the Checkout Branding API, are available only on Shopify Plus. We tell you which side of that line your idea sits on before it goes into a design.

Most checkout wins happen before checkout: clear shipping costs and delivery dates on the product page, fewer surprises in the cart, and trust signals at the point of decision.

Apps are one of Shopify's biggest strengths. Shopify's own comparison page lists more than 21,000 apps in its App Store. They are also the most common reason a store slows down, and the first thing our Shopify development audits look at. Each storefront app can add scripts, styles and network requests to every page, and the costs stack quietly. Six apps doing small jobs can weigh more than the whole theme.

The app audit we run on every store

1. List every installed app and what it touches: storefront, admin only, checkout or back office.
2. Measure the storefront cost of each one on product and collection pages, on a mid-range phone.
3. Find overlap. Two review apps, three popups and a leftover upsell tool are common.
4. Replace simple apps with theme code: size charts, badges, announcement bars, FAQ tabs and basic bundles rarely need a subscription.
5. Keep the apps that earn their weight: subscriptions, reviews with real volume, loyalty, search on large catalogs, and back-office tools that never load on the storefront.
6. Clean up leftovers. Uninstalled apps can leave code in theme files; we remove it.

The speed target for Shopify development is the same as any site we build. Google's Core Web Vitals define good as Largest Contentful Paint of 2.5 seconds or less, Interaction to Next Paint of 200 milliseconds or less and Cumulative Layout Shift of 0.1 or less, measured at the 75th percentile. Our Core Web Vitals guide explains each metric. Image-heavy product pages, carousels and late-loading review widgets are where Shopify stores usually fail them.

We build on both, so we have no reason to oversell either. Our team built the WordPress and WooCommerce store for Marc Anthony True Professional, a hair care brand selling across the US and Canada, with collection banners, complete-your-look cross-sells and a salon section, then handed it to the brand's in-house developer. Here is how the two platforms compare before you commit to Shopify development for a typical growing store.

Two details matter more than they look. Shopify's payments help confirms that third-party transaction fees apply to orders processed through third-party and alternate gateways, even if Shopify Payments is also active. And because Shopify uses fixed URL paths, every product and collection URL changes in a move from WooCommerce. If your store is mostly content with a few products, our WordPress website design work may fit better.

Migrating to Shopify without losing search traffic

• Export every product, collection, page, blog and image URL from the old store, plus top landing pages from analytics and Search Console.
• Map each one to its new Shopify URL and load the map through Shopify's URL redirect import. Shopify notes that a redirect only works when the old URL no longer loads a live page, so we test after products are live.
• Move product descriptions, reviews, alt text and metafields, not just titles and prices.
• Recreate customer accounts and order history where needed, and plan how customers set new passwords.
• Rebuild GA4, ad conversion tracking and Merchant Center before launch, and watch Search Console daily after.

A store nobody finds does not need a better theme. Shopify's Google and YouTube channel syncs products to Google Merchant Center, and for eligible US stores synced products can appear in the Google Shopping tab for free. The feed is only as good as the product data. Google's product data specification requires an ID, title, description, link, image link, price and availability, and strongly recommends a valid GTIN when one exists. Brand is required for most new products.

We pair the feed with on-page product markup. Google's product structured data guide says using both Merchant Center feeds and merchant listing markup improves eligibility and helps Google verify product data. Then our SEO team handles collections, internal links and content, and our AI SEO work makes product and buying-guide pages easy for AI answers to cite. Stores with a showroom should also read how to rank higher on Google Maps.

Questions to ask any Shopify developer

1. Will you build a custom theme or customize an existing one, and can our team still update it?
2. Which of our current apps would you remove, and what replaces them?
3. How do you test product, collection and cart pages for speed on mobile?
4. If we are migrating, who builds and tests the redirect map?
5. How will Merchant Center, product schema and conversion tracking be set up?
6. Who supports the store after launch?

Red flags

• Every feature request answered with another app.
• Theme files edited directly on the live theme with no copy or version history.
• A migration plan that never mentions redirects or Search Console.
• Checkout changes promised that your Shopify plan does not allow.
• No plan for product data, feeds or tracking.
