Ecommerce website design: what you're buying, what it costs and what makes a store sell

A design is only worth what can actually be built from it. That's why you pick the platform before design starts. In the US, the real choice comes down to five options, and each one limits the designer in a different way.

BigCommerce and Squarespace are hosted subscriptions with the checkout built in. BigCommerce's standard plans run roughly $39 to $399 a month, and Squarespace's commerce plans sit toward the low end of that range. What they do well is ready-made checkout, sales tax calculation and shipping connections to UPS, FedEx and USPS. Where they fall short is the theme. You design within whatever the system lets you override, so a custom checkout flow is usually out.

Shopify plans run from about $29 to $399 a month, with Shopify Plus starting around $2,300, and get you from sign-up to first order faster than anything else. The catch is an extra transaction fee if you don't use Shopify's own payment gateway, plus app subscriptions. Those apps often add $50 to a few hundred dollars a month, because features like subscriptions, bundles or advanced filters rarely come standard.

WooCommerce is the usual choice for budgets of $5,000 to $20,000. There's no platform fee, just hosting, from about $15 a month on a shared server to $300 or more on a managed one, plus premium plugins. The designer gets total layout freedom. That's great for unusual sales setups like a product configurator, and a trap in a simple store, where it's easy to design features nobody will maintain.

Magento, sold in its paid edition as Adobe Commerce, makes sense for large catalogs, multiple warehouses or selling into several countries. An open-source Magento build usually starts around $30,000, and Adobe Commerce projects often pass $100,000 once licensing and integrations are counted. On projects that size, the visual layer is the cheapest line in the budget, so don't cut corners there.

Here's a rule of thumb. If you sell in one country, have up to 500 products and want to launch within a quarter, a hosted platform wins on speed and predictable cost. If you sell in an unusual way, with a configurator, customer-specific pricing or plans to expand abroad with different logistics, open source and a custom design are worth it. Any designer charging more than a few thousand dollars should follow the six stages above in that order. If a quote skips the second or fourth stage, ask why.

A good-looking store and a store that sells aren't always the same design. The difference comes down to a few spots that only show up after a month of real traffic, so ask for them at the wireframe stage.

The product page answers questions in the order shoppers ask them. What is it? How much? Is it in stock? When will it arrive? What does shipping cost? What if it doesn't fit? If shipping cost first shows up in the cart, some buyers leave right there. Analytics will call it a cart problem, but it's really a product page problem.

Checkout should have as few fields as possible and should never force anyone to create an account. Every extra field adds a few percent to abandonment, and a ten-field form on a phone just drives people away. Design a flow for returning customers too: saved address, last shipping method, one screen to pay.

In a store with more than a few hundred products, site search brings in a big share of revenue, because it serves shoppers who already know what they want. The design needs to cover suggestions as people type, tolerance for typos, and a no-results screen that offers a sensible alternative instead of a blank page. Most quotes never mention those three screens.

Design for mobile first, not last. Most US ecommerce traffic comes from phones, and the classic mistake is category filters designed for a big screen and squeezed onto mobile as a list under the products that nobody opens. If your store is already live and you want better results rather than a new look, start with conversion optimization based on your current traffic and data instead of starting from scratch.

A digital agency gives you a team: a designer, a developer, a project manager and usually someone for copy. You're paying for coordination, and in return you get a predictable process with one person to talk to. Agency builds in the US typically start around $15,000 and can pass $100,000, and much of that pays for management rather than design. For a simple store, you're paying for structure you don't need.

A freelance ecommerce web designer charges $50 to $150 an hour and is the obvious choice for a project one person can hold in their head. The risks are availability and the fact that designers rarely code, so you still need a second person for the build. Only now you're the one hiring them and managing the handoff.

We fit in between. You describe the project once, and we match a vetted specialist or a small team to that scope, with experience building on the platform you've chosen. We don't have an in-house production team, so we have no reason to push a pricier platform than you need. If your project really does need Magento and a budget above $75,000, we'd rather tell you on the first call than have you find out halfway through.

Whoever you go with, check three things before you sign. First, does the copyright to the design transfer to you along with the source files, not just a license to use them? Second, who owns the accounts? Your domain, hosting, platform admin and ad accounts should all be registered to your company. Third, what happens after launch and what does an hour of fixes cost? Every store's first three months bring a list of small changes.

Once the store is live, your next job is traffic. Store SEO is the cheapest source over the long run, and product campaigns fed by Google Merchant Center bring sales in soonest. Plan both during the information architecture stage, because changing category URLs later costs more than getting them right the first time.
