eCommerce Web Design Services

A store loses people in four places. Design decides three of them.

Category, product, cart, checkout. Traffic is expensive and most of it leaves at one of those four screens. eCommerce design is the work of finding out which one, and fixing the reason.

Designed mobile first, because the traffic is Templates, not one-off product pages Your platform, your accounts, your data

Where the money leaks

Four screens, four completely different jobs

Most store redesigns treat these as one visual problem and give them one visual answer. They aren't. Each screen has a different question to answer and a different reason people leave.

Screen 01

Category

Job: narrow it down

  • Filters that match how buyers actually sort, not how your database is organised
  • Enough information on the tile to skip a click
  • Sort order that puts something worth buying first
  • A visible result count so nobody feels lost

Screen 02

Product

Job: answer the doubt

  • Images that show scale, texture, and the thing in use
  • Sizing, materials, and compatibility answered before they're asked
  • Delivery cost and timing visible here, not discovered at checkout
  • Returns stated plainly, because it's the last objection

Screen 03

Cart

Job: don't lose them here

  • Total including delivery, shown before they commit to anything
  • Editing quantities without a page reload
  • No surprise fees appearing one step later
  • An obvious way back to shopping that doesn't empty the cart

Screen 04

Checkout

Job: get out of the way

  • Guest checkout, because forced account creation costs orders
  • Only the fields genuinely needed to fulfil the order
  • Errors shown next to the field, in plain language
  • Nothing on screen that isn't helping them finish

How store design actually works

Nobody designs four hundred product pages. They design one.

This is the real difference between designing a store and designing a website. Almost every page is generated from a template, so the design work is building a system that holds up across your entire catalogue, including the awkward products.

Template 01

The product template

Has to work for your best photographed hero product and for the one with a single supplier image and a two line description. Designed against the worst case, not the showcase.

Template 02

The category template

Needs to hold nine products and nine hundred without either feeling broken. Filtering, pagination, and empty states all get designed rather than inherited from the theme.

Template 03

Variants and options

Size, colour, bundle, subscription. The messiest part of most stores, and the place where a theme's default behaviour quietly costs orders every day.

Template 04

The states nobody designs

Out of stock, no search results, failed payment, empty cart. Each one is a moment where a customer decides whether to try again or leave, and each one usually looks like an error page.

Designing against your real catalogue rather than a curated selection is the whole point. A template that only looks good with perfect photography is a template that will look wrong on most of your store.

Mobile

Most of your store traffic is on a phone, held in one hand

Which changes the design brief entirely. Desktop first stores get shrunk down until they technically fit, and then everyone wonders why mobile converts worse.

  • The buy button stays reachable. Scrolling past the add to cart and having to scroll back is a small friction that shows up in the numbers.
  • Images are the heaviest thing you ship. On a phone connection, product photography decides whether the page loads before someone gives up. Format and dimensions are design decisions, not afterthoughts.
  • Filters need to work with a thumb. A sidebar of tiny checkboxes on desktop becomes unusable on mobile unless it's designed separately.
  • Forms are where mobile really suffers. Correct input types, autofill that works, and as few fields as the order genuinely needs.
  • Nothing important hides behind a hover. There is no hover on a phone, so anything revealed that way is invisible to most of your customers.

Platform

We design for the platform you're on

Migrating a store is a serious project and it's rarely the answer to a design problem. If you're already selling on something that works, we design within it.

WooCommerce

Sits on WordPress, so design freedom is high and you keep full control of the site and its data.

Worth knowing

Performance depends heavily on how it's built and how many plugins accumulate, so restraint matters more here than elsewhere.

Shopify

Hosted, stable, and quick to launch on. Checkout is largely fixed, which removes both a risk and an option.

Worth knowing

Design effort concentrates on category, product, and cart, since checkout customisation is limited by the platform itself.

Something else

Larger or custom platforms are workable, and the design principles don't change even when the implementation does.

Worth knowing

We'll be straight with you about whether the build side is something we should take on or whether you need a specialist.

If your store also isn't getting found, that's a separate problem with a separate cause, and design won't solve it. It's covered on eCommerce SEO. Build work beyond design sits with web development.

Worth saying

Design can't fix everything a store gets wrong

Some conversion problems have nothing to do with how the store looks, and a redesign aimed at them is money spent in the wrong place.

Delivery cost is a pricing decision

If people abandon when they see the shipping total, no layout change fixes that. The honest answer is a commercial one, and we'd rather say so than redesign the cart.

Photography does a lot of the work

A product template can only present what it's given. If the images are weak, that's usually the highest return thing to spend on, ahead of design.

A quiet store isn't a design problem

If very few people are arriving at all, improving the conversion rate on that traffic changes very little. Getting traffic comes first.

Common questions

Questions we get about eCommerce design

No, and often you shouldn't. If the drop is concentrated on one screen, redesigning that template is faster, cheaper, and easier to measure than rebuilding everything.

Full redesigns make sense when the store has outgrown its structure or the platform is genuinely fighting you. Otherwise, targeted work usually wins.

From your own analytics, if it's set up to record the steps of the purchase journey. We look at where people stop rather than guessing from the design.

If that tracking isn't in place, getting it working is the first thing to do. Redesigning without it means nobody can tell afterwards whether it helped.

It can, and stores are more exposed than most sites because of the sheer number of URLs. Category and product URLs get preserved where possible and redirected properly where they can't be.

If your store gets meaningful organic traffic, that constraint gets built into the plan from the start rather than handled after launch. More on that under eCommerce SEO.

Usually yes, and it's frequently the sensible option. A well built theme with the templates redesigned around your actual products gets most of the benefit for a fraction of the work.

Where that breaks down is when the theme's structure is the problem, at which point patching it costs more than replacing it. We'll tell you which situation you're in.

No. It matters enormously for a store, and it's a specialism worth hiring properly for rather than getting as an add on from a design agency.

What we will do is tell you what the template needs: which angles, what aspect ratio, and which shots are doing the persuading.

You do, completely. The platform account, the domain, the customer data, and the store itself stay in your name throughout.

We work as a user on your accounts and that access can be removed at any point without anything breaking.
