Smirly
Smirly needed a fresh look and a move to Shopify. We led a conversion-focused ecommerce website design refresh and full replatform—streamlining merchandising and day-to-day management with our in-house team.

Our eCommerce Web Design Process
Here’s how we take you from idea to a live store that’s fast, findable, and easy to run. It’s the same playbook we’ve refined and perfected for years, with clear steps, no surprises, and one team carrying it through.
1) Discover & Align
We clarify business goals, customers, success metrics, requirements, and constraints, then map the systems and data that need to work together from the start.
2) Information Architecture & Wireframes
We plan how shoppers move through the site—site map, site structure, and user flows, then create wireframes for key templates (homepage, category, product, cart/checkout, account).
3) Design System & Prototypes
A modern, brand-right design system comes to life in responsive prototypes focused on clarity and conversion, so decisions are easy to review and approve.
4) eCommerce Site Build & Integrations
We code clean, maintainable templates and connect the tools you rely on (inventory, pricing, orders, payments, tax, shipping, analytics). Performance, accessibility, and security are addressed as we build, not after.
5) Content & Migration
Products, customers, orders, and content move over with validation so you’ll have a functioning new ecommerce website. We protect search equity with URL mapping, 301 redirects, and parity for metadata and structured data.
6) QA, Performance & SEO readiness
We test across devices and browsers, tune Core Web Vitals, validate structured data, confirm tracking, and make sure the experience is smooth and fast.
7) Launch & Continuous Optimization
Launch with monitoring, team training, and a monitoring and refinement plan, with CRO testing plus ongoing programs (SEO, paid media, email/SMS) if you want one team to keep the momentum.
eCommerce Website Design on Our Favorite Platforms
We deliver eCommerce website design and development on all kinds of platforms, but we’re experts on two platforms that our clients use most—Shopify and WooCommerce. We handle design, build, integrations, performance, and SEO with one in-house team.
Shopify eCommerce Websites
Shopify’s hosted platform keeps updates and security handled while giving your team an admin that’s easy to manage. We design custom themes and sections, extend checkout, and tune speed/SEO so the store stays fast and search-friendly.
- We create custom, brand-matched themes and sections rather than off-the-shelf templates, with clean code that’s easy to maintain.
- We implement app and system integrations—payments, tax, shipping, ERP/CRM—so product, order, and customer data stay in sync.
- We optimize Core Web Vitals with smart image strategy, script governance, and structured data to support visibility in search.
- We enhance checkout and merchandising tools to lift conversion and simplify day-to-day management.
WooCommerce Websites Built on WordPress
WooCommerce is ideal when rich content and storefront live together in WordPress. We craft editor-friendly designs, govern plugins the right way, and streamline checkout while tightening performance and analytics.
- We build custom blocks/themes so your team can publish quickly without breaking design or slowing the site.
- We manage plugins responsibly, harden security, and configure payments, tax, and shipping for a smooth checkout experience.
- We improve performance with caching, CDN, and media strategy, and set up analytics and event tracking for clear insights.
- We structure categories and product pages with logical structure and schema—ecommerce web design that supports long-term growth in search.
eCommerce Web Design FAQs
Do you offer custom eCommerce website design and enterprise solutions?
Yes. Every build is custom—designed to your brand and business rules—with discovery, UX, development, and integrations handled by our in-house team. We support complex catalogs, B2B features, and multi-system data flows.
Do you offer eCommerce redesign services?
Redesigns are a core service we offer all the time. We plan for SEO, redirects, and analytics parity so rankings hold or improve, then rebuild UX (navigation, category, PDP) to lift conversion and revenue.
Can you integrate with our ERP/CRM and other systems?
Yes. We connect ERPs (e.g., NetSuite, SAP, Dynamics), PIMs, CRMs, tax, payments, shipping/3PLs, and marketplaces so product, order, and customer data stay in sync. Clean integrations reduce manual work and improve customer experience.
What ecommerce website platforms do you work with?
We can handle most major eCommerce website platforms like Shopify and WooCommerce as well as platforms designed for larger catalogs like BigCommerce or Magento. We’ll recommend what fits your catalog, workflow, and growth plan.
How much does an eCommerce website cost?
We price custom projects based on scope. Your budget is shaped by things like catalog size and complexity, level of design customization, required features (e.g., product configurators, subscriptions, B2B account structures), third-party integrations (ERP/PIM/CRM, tax, shipping/3PL, marketplaces), content and data migration, compliance/security needs, performance targets, and timeline. But we can help you find the right path forward to match your budget and your needs.
How long does custom ecommerce website take to build?
Most custom eCommerce builds take a few months from kickoff to launch; complex projects (heavy integrations, multi-store, or extensive migration) take longer. We run a proven sequence: discovery & solution architecture → UX/UI design → development & integrations → content/data migration → QA & performance → launch & training.
The biggest timeline drivers are number of templates, depth of customization, integration lead times, data readiness, and feedback/approval cycles.
Will my site be responsive, fast, and SEO-friendly?
Yes. Our ecommerce website design and development is mobile-first, built to meet Core Web Vitals, and structured with clean information architecture and schema so products and categories are easy to find—and fast to use.
Will my eCommerce website be secure?
Yes. Every build ships with HTTPS, secure checkout patterns, and PCI-aware implementation. We follow best practices for data handling and keep platforms, apps, and dependencies up to date to reduce risk and protect customer data.
Can you migrate/replatform without losing SEO?
Yes. Our ecommerce web design services include SEO-safe replatforming: URL mapping, 301 redirects, metadata preservation, structured data parity, and post-launch validation in analytics and Search Console to protect rankings and traffic.
Is managing my eCommerce website easy?
It is. You’ll have an admin your team can use daily for products, categories, promotions, and orders, plus launch training. We keep code and components maintainable as part of our ecommerce web design approach, so routine changes are faster and safer.
Do you also handle marketing (SEO, paid media, email/SMS) after launch?
Yes. We run ongoing programs—technical and content SEO for ecommerce, Google/Microsoft Ads (Search, Shopping/PMAX), paid social, and lifecycle email/SMS (welcome, abandon, post-purchase)—aligned to revenue, not just traffic.
Do you build custom functionality?
If you can outline it, we can build it—product configurators, bundles, subscriptions, B2B account hierarchies, approval flows, custom pricing, and more—through custom ecommerce development that matches how you sell.
Can you import our products, customers, and orders?
Yes. We migrate products/variants, customers, orders, reviews, and content with careful mapping and validation. We also plan redirects and catalog changes to preserve SEO value during go-live.
Will I own my website and data?
Yes. You’ll own your theme/code (per contract), content, and data. We document accounts and environments and provide training so your team is self-sufficient.
Do you offer packages for startups and smaller catalogs?
We can scope streamlined Shopify or WooCommerce website design when requirements are simpler, with a clear path to expand features as you grow.
