Online Stores That Sell, Not Just Display — E-commerce Built for Revenue
We build e-commerce experiences where every pixel, every interaction, and every page is designed with one goal: converting browsers into buyers and buyers into repeat customers. At Desisle, e-commerce isn't just about setting up a store — it's about engineering a buying experience that maximizes revenue per visitor through speed, design, and conversion optimization.
The Pain Points That Brought You Here
Your conversion rate is below 2%.
Industry average for established e-commerce is 2.5-3.5%. You're leaving thousands in revenue on the table with every visitor who doesn't buy. The product is good — the buying experience is the problem.
Cart abandonment is above 70%.
Users add products, start checkout, and vanish. Too many form fields. Surprise shipping costs. No guest checkout. No trust signals. Every abandoned cart is a customer who WANTED to pay you but couldn't complete the process easily.
Your store is painfully slow.
4+ second load times on mobile. Unoptimized product images. No CDN. Bloated theme with 30 unused apps. Every extra second costs you 7% in conversions. Your store is literally hemorrhaging money through load times.
You've outgrown your template.
The Shopify theme you bought for $80 can't handle your 500-product catalog, your custom subscription logic, or your holiday traffic spikes. It breaks when you try to customize it. It wasn't built for your scale.
Mobile experience is awful.
70% of your traffic is mobile but the checkout was designed desktop-first. Product images don't zoom properly. Filters are painful. The "Add to Cart" button requires scrolling past 3 screens of description.
You want to sell globally
but your store only handles one currency, one language, and one shipping zone. International visitors bounce because they can't see prices in their currency or estimate their shipping cost.

Our Process
Phase 1 — Discovery & Strategy (Week 1)
We don't just ask "what do you sell?" We dig into your business model, margins, customer behavior, and competitive landscape to design a store optimized for YOUR economics.
- Business analysis (AOV, margins, repeat purchase rate, customer segments)
- Competitor store audit (UX patterns, pricing display, checkout flows, upsell strategies)
- User journey mapping (from ad/search → product discovery → cart → checkout → post-purchase)
- Technical requirements gathering (integrations, shipping logic, subscription needs, multi-currency)
- Platform recommendation with justification
Phase 2 — UX/UI Design (Weeks 2-4)
Every page is designed for conversion, not just aesthetics.
- Homepage: hero, bestsellers, trust signals, CTA hierarchy
- Collection/category pages: filtering, sorting, product cards, load-more patterns
- Product detail pages: gallery, variant selector, reviews, upsells, trust badges, add-to-cart optimization

Our E-commerce Philosophy
1. Speed is revenue. Every 100ms of load time improvement increases conversion by 1.11%. We obsess over performance — image optimization, code efficiency, CDN configuration, caching — because milliseconds equal money.
2. Mobile is the store. 70%+ of e-commerce traffic is mobile. We design mobile-first, test mobile-first, and optimize mobile-first. Desktop is the afterthought, not the other way around.
3. Checkout is the bottleneck. Most stores lose 60-80% of customers at checkout. We design checkout flows with surgical precision — fewer fields, guest checkout, multiple payment options, trust signals, and clear progress indicators.
4. The store is the beginning, not the end. Launching a store without marketing is like opening a restaurant on a deserted island. We connect you with our SEO, paid ads, and email marketing teams to drive traffic from Day 1.
