E-commerce UI/UX Design Services

E-commerce UX that turns traffic into predictable revenue

Your store is getting visitors, the campaigns are running, but revenue is not where it should be. When we look under the hood, the problem is usually not the media spend, it is friction in the experience: unclear product pages, slow mobile, or a checkout that makes people stop and think.

BYBOWU designs and builds conversion-focused e-commerce UI/UX for founders and marketing leaders who want measurable impact, not another visual refresh. We are headquartered in Phoenix, AZ and work with Shopify, WooCommerce, Magento, BigCommerce, and headless stacks for brands across the US and worldwide.

If your goal is higher conversion rates, larger average order value, and more repeat customers, we turn your store into a system you can test, measure, and keep improving.

The problems we usually walk into

Most e-commerce teams come to us with one or more of these issues:

• High traffic, low conversion: Paid and organic channels are working, but PDPs and category pages leak visitors.
• Cart and checkout abandonment: Users show intent, then disappear before payment.
• Poor mobile experience: Slow, clunky flows on phones where most of the traffic lives.
• Messy analytics: GA4 exists, but nobody fully trusts the data or knows which drop-offs to attack first.
• Inconsistent UX across features: Years of quick fixes have produced a confusing, fragile experience.

If this sounds familiar, you do not need more design opinions. You need a structured, data-backed UX process that ties each change to a clear metric.

How our e-commerce UI/UX process works

We treat e-commerce UX as a revenue function. Every step is senior-led and designed to reduce risk for your team.

1. 1. Discovery and UX / CRO audit
   We review your analytics (GA4), heatmaps, session recordings, and actual store flows. We run heuristic audits on PDP, PLP, cart, checkout, and account, then agree on KPIs like conversion rate, AOV, and repeat purchase rate.
2. 2. Journeys, flows, and low-fidelity wireframes
   We map critical journeys (first-time buyer, returning buyer, subscriber, B2B buyer) and sketch flows that remove friction. This is where we simplify steps, reduce inputs, and clarify choices before anyone starts pushing pixels.
3. 3. High-fidelity UI and design system
   We design responsive layouts for PDP, PLP, cart, checkout, and account with clear hierarchy, states, and micro-interactions. You get a reusable component library that your team or ours can implement consistently.
4. 4. Implementation on your stack
   We implement or collaborate with your dev team on Shopify, WooCommerce, Magento, BigCommerce, or a headless build using tools like Next.js with APIs and your existing backend. Performance, accessibility, and SEO fundamentals are part of the work, not an add-on.
5. 5. Validation, testing, and iteration
   We configure GA4 enhanced e-commerce events, funnels, and dashboards, then run A/B tests with tools like VWO or Optimizely to validate improvements before rolling them out fully.

You stay close to the work through regular check-ins, Loom walkthroughs, and shared boards where you can comment directly on designs.

What you get: concrete deliverables

We do not leave you with pretty mockups that never make it to production. A typical e-commerce UI/UX engagement includes:

• UX / CRO audit with a prioritized roadmap, effort vs impact estimates, and clear KPI targets.
• Responsive UI kit and component library in Figma, tailored to your brand and ready for development.
• High-fidelity designs for key templates: PDP, PLP/search, cart, checkout, account, onboarding, and common modals such as size guides, quick add, and wishlists.
• Micro-interaction specs for add-to-cart, form validation, error states, progress indicators, and empty states.
• Implementation support or full build on Shopify, WooCommerce, Magento, BigCommerce, or headless with Next.js and your existing backend.
• GA4 dashboards and experiment plans so your team can monitor performance and keep optimizing without guessing.

Whether you are an early-stage brand proving product-market fit or an established retailer fighting for incremental lift, we right-size the engagement to your team, budget, and timeline.

Where we usually move the needle: PDP and checkout

Two areas almost always create the biggest lift: product detail pages and checkout. We focus there first, then expand to navigation, search, and merchandising.

Product pages built to sell, not just show

• Above-the-fold clarity: Title, price, key benefits, stock, and a clear CTA visible immediately, especially on mobile.
• Conversion-focused layout: Sticky add-to-cart, intuitive variant selectors, and contextual cross-sells like bundles or frequently bought together to increase AOV.
• High-quality media: Zoomable images, 360 views, short video demos, and user-generated content to reduce uncertainty and returns.
• Social proof and reassurance: Reviews with filters, Q&A, comparison blocks, and clear shipping and returns information near the price, not hidden in the footer.

Checkout that removes friction instead of adding doubt

• Streamlined cart: Clear line items, easy quantity edits, upfront shipping estimates, and save-for-later where it helps.
• Fast, flexible checkout: Guest checkout by default, with simple post-purchase account creation for customers who want it.
• Smart forms: Address autocomplete, real-time validation, and readable error messages that explain what to fix.
• Modern payment options: Express payment such as Shop Pay, Apple Pay, Google Pay, and PayPal, plus relevant local methods for your markets.
• Trust and transparency: Visible security badges, clear returns and warranty policies, concise progress indicators, and a constant order summary.

The result is a buying experience that feels fast and trustworthy instead of stressful or confusing.

Data, CRO, and ongoing optimization

You cannot improve what you cannot see. We make analytics and experimentation part of the foundation, not something you add a year later.

• GA4 enhanced e-commerce: Proper event tracking for product views, add to cart, checkout steps, and purchases, wired into funnels and attribution views that decision makers can actually read.
• Behavior tools: Heatmaps, session recordings, and on-page polls using tools like Hotjar or FullStory to understand why customers behave the way they do.
• A/B testing: Structured experiments on messaging, layouts, CTAs, bundles, and pricing presentation using tools like VWO or Optimizely.
• Documented learnings: Clear experiment summaries so your team knows what worked, what did not, and what to test next.

Many clients keep us on for monthly UX reviews, CRO roadmaps, and test cycles tied to specific KPIs instead of big-bang redesigns every few years.

How engagement works

We keep collaboration straightforward so you always know what is happening and why.

• Step 1 – Intro and quick review: You share your goals, current metrics, and tech stack. We often do a light UX and analytics review before the first call, so the conversation is grounded in reality.
• Step 2 – Proposal and roadmap: We outline scope, timelines, and investment, including quick wins you can ship fast and deeper UX changes that need more time.
• Step 3 – Design and implementation: We work in weekly or biweekly sprints with demos, design reviews, and clear ownership between our team and yours.
• Step 4 – Launch and measure: We deploy or support your dev team, stabilize, and monitor key metrics. Then we adjust based on real user data, not opinions.
• Step 5 – Optional ongoing CRO: Monthly insight reports, test plans, and rollout of winning ideas so growth does not stop at launch.

If you are near Phoenix we are happy to meet in person. If you are elsewhere in the US or internationally, we run everything remotely with the same level of structure and visibility.

Next step: share a brief about your store, current numbers, and what success looks like for you. We will respond with a focused plan, not a generic pitch.
