E-Commerce Website Design That Is Built to Sell, Not Just to Look Finished

Shopify store, product pages, tracking and Google, ready to take a paid visitor on day one

E-commerce website design is the work of building an online store that can take a visitor from a Google ad or a search and turn them into an order: the product pages, the collections, the checkout, and the tracking that tells you which of them did the work. We build on Shopify, connect Google Merchant Center, install GA4 and conversion tracking before launch, and hand the store to you outright, From $2,500 one-time. Design is the part everyone talks about and the least of what makes a store sell.

Why do most new online stores go live unable to sell?

A store can look finished and still be unable to turn a visitor into an order. Most small e-commerce builds go live in exactly that state, because the parts that sell are the parts nobody sees on the mock-up.

  • ✗No conversion tracking, so the first month of ads produces a spend figure and nothing else
  • ✗Product pages with two photographs, no size or ingredient information, and a description copied from the supplier
  • ✗Collections organised the way the warehouse thinks, not the way a customer searches
  • ✗Merchant Center never connected, or connected with a feed Google rejects half of
  • ✗Shipping, returns and policies written on launch day and wrong by the first order
  • ✗A theme chosen for the demo store's photography, slow on a phone with yours

The cost shows up as ad spend that cannot be evaluated. A store without tracking cannot tell you whether the product page, the price, the shipping or the traffic was the problem, so the only lever left is spending more. We build in the opposite order: what has to be true for a paid visitor to become an order, then the pages around it.

What Does the Build Include?

Shopify store and theme set up around your products, not the theme demo's
Homepage, product pages, collections, checkout, shipping and returns policies
Product page structure that answers the buying question: photographs, specifications, sizing, ingredients, reviews
GA4 and conversion tracking installed and tested with a real order before launch
On-page SEO and Product, Organization and Breadcrumb schema
Google Merchant Center connected, the feed validated and disapprovals cleared
Google Ads launch preparation: conversion actions, audiences and a Shopping campaign structure ready to switch on
Full handover: the store, the accounts and written instructions are yours

How Does a Visitor Become an Order?

Every step is built and measured before the first dollar is spent on traffic.

Shopify vs WooCommerce vs Custom Build: Which Should a Small Brand Use?

We build on Shopify and this table is why. It is not the right answer for every brand, and the rows where it loses are printed too.

Do you build e-commerce websites locally in Orange County?

Yes. The build is done remotely for brands anywhere in the United States, and in person for product brands in Orange County: product photography sessions, a walk through the catalog with whoever manages it, and training in your office rather than on a call.

Orange County has an unusual number of small product brands: supplements in Irvine, apparel and surf in Huntington Beach and Costa Mesa, food and beauty across the county, many of them selling wholesale or on Amazon and adding their own store second. That is the brand this build is designed for: a product that already sells, and a store that has to sell it without a full-time team behind it.

Based in Costa Mesa. E-commerce website design for businesses in:

  • Costa Mesa
  • Newport Beach
  • Irvine
  • Huntington Beach
  • Santa Ana
  • Fountain Valley
  • Tustin
  • Anaheim
  • Orange
  • Garden Grove
  • Fullerton
  • Laguna Beach
  • Mission Viejo
  • Lake Forest

Anywhere else in Orange County too, and remotely across Southern California — see our Orange County page.

What Does an E-Commerce Website Cost?

From $2,500

One-time. The figure moves with how many products the store carries, how much of the copy and photography exists, and whether there is an old store to migrate. Fixed in writing after one call.

Shopify's subscription is paid by you, directly to Shopify. After launch you own the store outright. If you want us running the store and the Google campaigns together, that is Website + Google Management from $2,000/month.

Launch My Online Store

How Do We Build It?

1

Catalog, customer, fixed quote

One call about the products, who buys them and where the traffic will come from. We audit what exists, check the category on Google Shopping and send a page list and a fixed price in writing.

2

Build from the product page out

Product pages and collections first, because they decide whether anything sells; homepage and theme after. Tracking and Merchant Center are wired while the store is still private, and you review a working store.

3

Test with a real order, launch, hand over

We place a real order end to end, confirm it lands in GA4 and Ads with its source, then launch on your domain and hand over every account. Most stores go live in four to six weeks.

Frequently Asked Questions

How much does an e-commerce website cost?
Our build starts at $2,500 one-time and is fixed in writing after one call. What moves the figure above the floor is size and what already exists: a catalog of forty products with photographs and descriptions is a smaller job than one of four hundred with neither, and migrating an old store with order history and URLs that rank is a job of its own. Shopify's subscription and card processing are paid by you to Shopify and are listed with the date we checked them on our Shopify management page. After launch you owe nothing further; ongoing management, if you want the store and the Google campaigns run together, is $2,000 per month and is separate. Before choosing anyone, ask for the tracking to be demonstrated with a real order before launch. A store that goes live without it has no way of telling you what your first month of advertising did.
How long does it take to launch an online store?
Four to six weeks for most stores, counted from the day we have the product data, and the product data is the usual reason it takes longer. Photographs, descriptions, prices, variants, weights for shipping and the policies all have to exist before a product page can be built properly, and a store with three hundred products needs them three hundred times. We start on the product pages first because they decide whether the store sells, then collections, then the homepage and theme, so you review real pages within the first two weeks rather than a design at the end. Merchant Center review adds its own clock: Google checks a new store before Shopping ads can run, and that can take days that are outside anyone's control. If you have a launch date, such as a season or a trade show, tell us on the first call and we plan back from it.
Why Shopify and not WooCommerce or a custom build?
Because a small brand should not be running infrastructure, and the table above is the longer version. Shopify hosts the store, maintains the checkout, handles the card processing and keeps the catalog synced to Google through its own channel app, which removes most of the things that break on a self-hosted store and most of the reasons to pay a developer monthly. WooCommerce is free software on top of WordPress that you host and maintain, which is a good fit for a content site adding a small shop and a poor fit for a brand whose store is the business. A custom build makes sense only when the product cannot be sold through a standard cart, such as a configurator or unusual pricing logic, and that is rare under a few million in revenue. Where Shopify loses is deep checkout customisation; if you need that, we will say so and point you elsewhere rather than build around it.
Do you write the product descriptions and take the photographs?
Descriptions, yes, and they are part of the quote: we write each product page to answer the buying question, which means specifications, sizing, ingredients or materials, what it is for and what it is not for, in your voice rather than the supplier's. Photography is quoted separately because it depends on the catalog. For brands in Orange County we run product photography sessions in person; for brands elsewhere we work from what you have and tell you honestly if it is not enough, because a product page with two photographs loses the sale even when the ad won the click. What we will not do is generate fake reviews, invent specifications or copy a competitor's text. If your catalog is large, we prioritise the products that carry the revenue and template the rest, and the quote says which is which.
What happens after launch?
You own the store, the accounts and the written instructions, and you can run it yourself from that day. Most brands do for a while. What tends to bring them back is the week-to-week work a store needs once traffic arrives: new products and collections, promotions, conversion work on the pages the data says are losing orders, the Google feed after every catalog change, and the campaigns pointed at it. That is our Shopify management service at $2,000 per month, which runs the store and the Google Ads together so the traffic and the page it lands on stop being two separate problems. It is a separate decision from the build and there is no obligation either way. If you go elsewhere for it, everything we built is standard Shopify and any competent manager can pick it up.
Can you migrate my store from Wix, WooCommerce or BigCommerce?
Yes, and a migration is mostly about the things you cannot see. Products, images, customers and order history move across with Shopify's import tools and some cleaning; the parts that need care are the URLs that already rank, which have to be redirected one by one so the search visibility you built is not lost, and the tracking and email tools that have to be reconnected on the new store. We map the old URLs before anything moves, keep the old store live until the new one has taken a real order, and switch the domain last. What we tell every brand first is that a migration is the moment to fix the product pages rather than copy them, because moving a page that did not convert produces a page that does not convert on a different platform. The quote says which pages we would rewrite and why.
