There are two types of ecommerce design agencies. The first type makes your store look better. The second type makes your store perform better — and usually, as a byproduct, it looks better too. The distinction matters enormously when you’re evaluating partners, because a beautiful store that doesn’t convert is just expensive decoration.
The best ecommerce design agencies think like your customer first and your creative director second. They start with where customers drop off, what’s creating friction, what trust signals are missing, and what the data says — before they open a design tool. The design decisions that follow are answers to those questions, not expressions of aesthetic preference.
What a Proper Ecommerce Design Engagement Includes
Conversion Audit First
Before any new design work starts, a good ecommerce agency audits what you have. Where are customers landing? Where are they dropping off? What’s the add-to-cart rate on your product pages? What’s the cart abandonment rate? What do heatmaps show about where attention goes and where it doesn’t?
This audit shapes the entire design strategy. The highest-leverage problems get fixed first. CRO without data is guessing with a higher design budget.
Product Page Design
The product detail page is where buying decisions are made. It’s the highest-leverage page on any ecommerce site — and the most commonly underinvested. A well-designed PDP answers every question a customer might have before they can ask it: what is this exactly, why should I trust it, what do other people say about it, what am I getting, and how do I get it?
At Splash Creative, product page redesigns are one of the most common and highest-ROI engagements we take on. Focused PDP work often produces conversion improvements within 30 days of launch.
Collection and Navigation Architecture
Customers who can’t find what they’re looking for leave. Collection page structure, navigation logic, and search functionality determine whether someone who arrives interested actually reaches the product they want. This is especially important for brands with large or complex catalogs.
Checkout Optimization
The checkout is where money is left on the table more than anywhere else. Unnecessary fields, confusing shipping options, lack of trust signals at the payment step, no guest checkout — these friction points cost real revenue every day. A good ecommerce agency treats checkout optimization as a distinct discipline, not an afterthought.
Mobile-First Design
Most ecommerce traffic is mobile. Most ecommerce design is still built desktop-first and adapted for mobile. The result is a mobile experience that feels like a compromise rather than an intentional design. Every store Splash Creative builds is designed mobile-first — the desktop experience expands from mobile, not the other way around.
Brand Coherence Across Every Touchpoint
A customer who sees your ad, clicks to your site, adds to cart, and receives your post-purchase email should feel like they’re in the same brand experience at every step. When the store looks different from the ads and the emails look different from the store, trust erodes. An ecommerce agency that also handles email marketing and brand keeps that coherence intact without you having to police it.
What to Look For When Evaluating Ecommerce Agencies
Conversion Data, Not Just Portfolio Screenshots
Ask for before-and-after conversion rate data from past clients. Any agency that can’t share this either doesn’t track it (a problem) or doesn’t produce results worth sharing (a bigger problem). The portfolio should show you what the store looks like. The case study should tell you what changed after launch.
Shopify Expertise
For most DTC and ecommerce brands, Shopify is the right platform. Ask about the agency’s Shopify-specific experience — custom theme development, Shopify Plus, Liquid templating, app integrations. Generic web design skill doesn’t automatically transfer to Shopify expertise. See our guide on Shopify design and development for more on what good Shopify work looks like.
Scope That Matches Your Actual Problem
Not every ecommerce problem requires a full store redesign. Sometimes the highest-leverage fix is the product page. Sometimes it’s checkout. Sometimes it’s the mobile experience. A good agency scopes the engagement around your actual problem — not around the largest project they can sell you.
Frequently Asked Questions
How much does an ecommerce design project cost?
A full storefront redesign with a boutique agency typically runs $20,000–$60,000 depending on scope and platform complexity. Focused engagements — product page redesign, homepage overhaul, checkout optimization — run $8,000–$20,000. The right investment depends on what’s actually limiting your conversion rate and revenue.
How long does an ecommerce redesign take?
A full storefront redesign typically takes 10–16 weeks. Focused PDP or homepage projects can run 4–6 weeks. Timeline depends on scope, content readiness, and decision-making speed on the client side.
Should I redesign my whole store or just the product pages?
Depends entirely on where your conversion problem lives. If your traffic is healthy and your add-to-cart rate is low, the product page is the problem. If customers are adding to cart but not completing checkout, that’s a different fix. Start with a conversion audit before committing to a scope — the data will tell you where the leverage is.
Do I need a separate agency for email and Shopify design?
Not if you can avoid it. The brands with the most coherent customer experience work with a single agency that handles both. When your Shopify store and your Klaviyo flows come from the same team, the experience is consistent and the revenue data flows both ways — store behavior informs email strategy, and email performance informs store decisions. At Splash Creative, we handle both under one retainer.
If your store isn’t converting the way it should, start with a conversation. We’ll look at your current setup honestly and tell you exactly where the problem is.
