In shortE-commerce UI UX design shapes the user interface (UI) and user experience (UX) of a retail business beyond the checkout funnel: site search, merchandising, loyalty, omnichannel journeys and seller tools. Our engagements for retailers, direct-to-consumer (DTC) brands, marketplaces and business-to-business (B2B) sellers run 4–8 weeks, cost $25,000–$60,000, and ship on Shopify, Adobe Commerce or Salesforce Commerce Cloud.

Definition

What is e-commerce UI UX design?

E-commerce UI UX design is the design of every customer-facing and staff-facing screen a retail business runs, from site search and loyalty accounts to the seller dashboard of a marketplace. The work connects the online store with physical stores and customer service, so shoppers meet 1 brand in every channel.

Merchandisers manage search rules, store associates fulfil buy online, pick up in store (BOPIS) orders, and marketplace sellers manage payouts, each in a different tool. Conversion work on product listing pages, product detail pages and checkout belongs to our e-commerce UX design services; this page covers the wider commerce operation around that funnel.

Which commerce experiences do we design beyond checkout?

We design 6 types of e-commerce products: site search and navigation, merchandising tools, loyalty and account areas, omnichannel journeys, marketplace seller dashboards and B2B commerce portals.

Site search and navigation

Autocomplete and zero-result pages turn vague queries into products, for example typo-tolerant suggestions grouped by category and brand.

Merchandising tools

Merchandisers pin, boost and bury products, for example a rule editor that previews the first 24 results.

Loyalty and account areas

Members check points, tiers and order history, for example a tier-progress card showing points left before free shipping.

Omnichannel journeys

Shoppers move between app, website and store, for example BOPIS order status and returns started online.

Marketplace seller dashboards

Third-party sellers manage listings, stock and payouts, for example a bulk listing upload with row-level errors.

B2B commerce portals

Trade buyers order against negotiated prices, for example quick order by stock keeping unit (SKU) and purchase-order approval.

Benefits

What UX challenges are specific to e-commerce?

4 UX challenges are specific to e-commerce: search queries in shopper language, catalogue data quality, channel inconsistency and the needs of 2-sided marketplaces.

Search queries in shopper language

Shoppers type "red dress for a wedding" while the catalogue uses internal names, so search design depends on synonyms and zero-result pages.

Catalogue data quality

Missing attributes and inconsistent sizes break filters, so designers specify the attributes each category requires.

Channel inconsistency

Prices, stock and points differ between app, website and store when systems disagree, so screens show when stock data was updated.

Two-sided marketplace needs

Sellers want fewer listing fields and shoppers want complete product information, so research covers both sides together.

Process

How does our e-commerce UI UX design process work?

Our commerce design process takes 4–8 weeks (20–40 working days) and runs in 5 steps, from the platform and catalogue review to the platform-ready handover.

3–5 days

Platform and catalogue review

We review the platform, for example BigCommerce, the search engine such as Algolia, and the product information management (PIM) data behind filters.

4–8 days

Shopper and staff research

We analyse site search logs for zero-result queries and interview shoppers plus merchandisers, store associates or sellers.

8–15 days

Journey and tool design

Designers produce search, loyalty or seller screens as a Figma prototype, reusing platform components where the theme supports them.

3–7 days

Testing with shoppers and staff

5 shoppers per round test search tasks, and 3–5 staff users test merchandising or seller tasks with real catalogue data.

2–5 days

Platform-ready handover

Developers receive Figma files mapped to Shopify sections or Salesforce Commerce Cloud components.

Comparison

E-commerce UX vs content website UX

E-commerce UX designs revenue journeys that cross channels and staff tools; general product UX designs tasks inside 1 application. Catalogue data, promotions and payment rules shape almost every commerce screen.

Pricing

How much does e-commerce UI UX design cost?

Commerce design work costs $25,000–$60,000 for a 4–8 week research and design sprint. The price depends on 4 factors: the platform's theme limits, the number of channels, the user groups beyond shoppers and catalogue data quality.

A site search and zero-result redesign for a Shopify store with 1 catalogue sits near $25,000. A marketplace with a shopper app, seller dashboard and loyalty program across 3 channels sits near $60,000.

Standards & compliance

Which payment, accessibility and review rules shape e-commerce UX?

5 standards and regulations shape e-commerce UX:

  • PCI DSS v4.0: requirement 6.4.3 makes teams authorise every script on payment pages, so designers keep third-party widgets out of the payment step.
  • WCAG 2.2 level AA: product images need alt text, filters need keyboard access and add-to-cart buttons need targets of at least 24×24 CSS pixels.
  • ADA Title III: US courts apply the ADA to online stores, so fixes go into templates instead of an overlay widget.
  • California Consumer Privacy Act (CCPA) and General Data Protection Regulation (GDPR): cookie banners and loyalty sign-up consent need choices with equal visual weight.
  • Federal Trade Commission (FTC) Rule on Consumer Reviews and Testimonials (16 CFR Part 465): fake reviews and review suppression are banned, so review displays show every star rating and label incentivised reviews.

FAQ

E-commerce UI UX design FAQs

These answers cover the 5 questions retail and marketplace teams ask most about commerce design beyond checkout.

Still have a question?

A design lead answers every message within one business day.

Talk to a design lead
Do you design marketplace seller dashboards?

Yes. Seller dashboard design covers onboarding, bulk listing upload, stock, orders, returns and payouts, and each flow is tested with 3–5 real sellers before development.

Does commerce design work include site search?

Yes. Site search design covers autocomplete, ranking rules, results filters and zero-result pages, with the top 100 queries from site search logs used as test material.

Can a Shopify store support a custom loyalty program design?

Yes. Shopify loyalty apps such as Smile.io and Yotpo expose theme blocks and APIs, so a custom points and tiers design ships without a headless rebuild.

Is B2B commerce design different from retail store design?

Yes. B2B buyers order against negotiated prices, credit terms and approval limits, so B2B portals need quick order by SKU, saved lists, purchase-order approval and invoice history instead of promotional banners.

How long does an e-commerce design project take?

An e-commerce design project takes 4–8 weeks, which equals 20–40 working days. A multi-brand storefront with a shared design system takes 8–16 weeks and costs $60,000–$180,000.
