Shopify Design And Build For Stores That Have To Sell

Store setup, theme customization, apps, and migrations, with the catalog treated as the thing that actually decides revenue. You own the store, the theme files, and every account.

Komplex designs and builds Shopify stores from Austin, Texas, with a presence in New York City and Reykjavik. The work covers store setup, theme customization, app selection and cleanup, checkout and subscription flows, and migrations from WooCommerce, BigCommerce, or a custom store. We are a Google Partner, and paid search runs alongside this work. The product catalog gets built once, for the store and the Google Shopping feed together. It sits inside our web design and development service.

You Own The Store

No Long Contracts

The Theme Is The Easy Part. The Catalog Decides Whether The Store Sells.

Shopify themes are good now, and a competent one costs less than a day of development. What separates stores that sell from stores that look nice sits underneath. How products are titled, how variants are structured, which collections exist and why, and what happens when something goes out of stock. Then whether the catalog behind your product pages also feeds your Shopping ads without contradicting them. We have watched a store lose money for weeks because the price in the feed and the price on the page disagreed by four dollars. Nobody was looking at both.

Where This Page Stops

This page is about building and moving stores. Ranking one is a different job with a different method. It lives on our ecommerce SEO page: collection architecture, faceted navigation, canonical rules, and the crawl. The two get planned together because the catalog is shared, but they are separate services and you can buy either without the other.

What We Do On Shopify

Five lines of work. Most Shopify projects that reach us are a migration or a store that has grown past the theme it started on.

Store Setup

A new store built properly the first time: catalog structure, collections, navigation, shipping, taxes, and the settings nobody revisits once the store is live.

Theme Customization

Working inside a good theme rather than rebuilding one. Faster, cheaper, and it survives theme updates, which a heavily hacked theme does not.

Migrations

WooCommerce, BigCommerce, or a custom store onto Shopify, with the URL map, the redirects, and the product data planned before anything moves.

Apps And Checkout

Choosing the few apps that earn their monthly fee and removing the ones that do not, plus subscription and checkout flows where the plan supports them.

Catalog And Feed

Titles, variants, availability, and identifiers built so the store and the Shopping feed say the same thing. This is where the money quietly leaks.

Start With The Store URL

Send the address. Theme, app count, load speed, and most of the catalog structure are readable without any access.

What Does A Shopify Agency Do, And What Should You Not Ask One For?

A Shopify agency designs, builds, customizes, and migrates stores on Shopify. The work covers store setup and configuration, theme selection and customization, and custom theme development. It also covers app selection and integration, checkout and subscription flows, data migration from another platform, and ongoing support. Shopify handles hosting, security, and payments itself. A Shopify agency spends its time on the storefront, the catalog, and the systems around them rather than on servers.

What you should be careful asking a small agency for is deep custom development on Shopify Plus, headless builds, or anything requiring a permanent engineering team. Komplex works within theme customization, setup, apps, and migration. Contract developers we have used for years deliver it, directed by one senior lead. If a project needs more than that, we will say so rather than learn on your store.

We look at the theme and its update status, the app load and what each app costs you monthly, and the speed on a phone. Then the collection and variant structure, and whether the catalog matches the Shopping feed. You get everything ranked by what it is costing you.

Common Questions About Shopify Builds

Can you migrate our store from WooCommerce to Shopify?

Yes, and it arrives more often than any other Shopify project. Products, variants, customers, and orders all move across. The URL map decides the outcome. WooCommerce and Shopify structure product and category addresses differently, so every old URL needs a destination and a redirect before the switch, not after it.

Shopify or WooCommerce for a new store?

Shopify if you would rather rent the checkout, the payments, and the security than own them. Also if your team wants to add products without a developer. WooCommerce if you are already on WordPress, prefer owning everything outright, and have someone to maintain it. Shopify costs more monthly and less in attention. That trade is the whole decision.

Custom theme or theme customization?

Customization, almost always. Shopify themes are good, they receive updates, and a customized good theme launches faster and costs less than a custom one. A fully custom theme makes sense when your merchandising fits no existing theme, and that is rarer than agencies suggest.

Which Shopify apps do we need?

Fewer than you have. Apps accumulate, each one adds monthly cost and page weight, and several usually overlap. The audit lists what is installed against what it costs you every month, and that conversation often pays for itself before any build work starts.

Do we own the store and the theme files?

Yes. The Shopify account, the theme, any custom code, and every app subscription sit in your name. We work through staff access you can remove at any time, and if we part ways nothing stops working.

How is this different from your Ecommerce SEO page?

This page is about building and moving the store. Our ecommerce SEO page is about ranking it: collection architecture, faceted navigation, canonical rules, product page templates, and the crawl. The catalog is shared between the two, so we plan them together, but they are separate services and either can be bought alone.

Send The Store URL And We Will Tell You What It Is Leaking

No access needed to start. Back comes the theme status, the app load and what it costs monthly, the speed, and whether the catalog and the feed agree.
