Ecommerce sites that earn every basis point of conversion.
Side Studios is a Shopify Plus and ecommerce design partner for brands already doing volume — the ones where a single basis point of conversion is real money and the constraint is a checkout, a replatform, or a CRO ceiling, not a store to spin up from scratch. As a Shopify Partner, we redesign and replatform for revenue, wiring the integrations — ERP, 3PL, subscriptions — where your margin actually lives.

THE PROBLEM
Traffic's fine. The checkout's leaking.
At scale, the problem is rarely getting people to the site — it's the revenue quietly lost between the product page and the thank-you screen. A theme that was fine at $1M is a ceiling at $10M: the checkout adds friction, the PDP buries the thing that sells, and the platform can't hold the integrations your ops team now depends on. If you're launching a first store, an off-the-shelf theme is the right call and this isn't for you. If you're a brand where a basis point of conversion is measured in dollars, a generic rebuild is a tax.
We design and replatform for revenue, not for a template swap. CRO on the paths that actually pay — PDP, cart, and checkout — so more of the traffic you already have converts. A migration to Shopify Plus that preserves SEO, URLs, and revenue instead of gambling them. And integrations that hold at scale — ERP, 3PL, subscriptions, and your ESP wired so margin and operations survive the growth. The value in an ecommerce build lives between the systems, and that's where we work.
WHAT WE BUILD
Built to sell at scale.
Every section earns a conversion job. Here is what goes into a Shopify Plus build.
Replatform without the dip
A migration to Shopify Plus that protects SEO, URL structure, and revenue — redirects mapped, rankings held, and the launch staged so growth continues through the switch instead of cratering on go-live.
CRO on the paths that pay
Product page, cart, and checkout optimized against the metrics that move money — revenue per basis point of conversion, not vanity engagement — so the traffic you already buy converts harder.
Checkout & Shop Pay economics
The one step where revenue is decided, treated as the priority. We reduce friction through the checkout and Shop Pay so fewer full carts abandon at the last screen.
Integrations that hold
ERP, 3PL, subscriptions, and your email platform wired into the store so inventory, fulfilment, and lifecycle revenue survive scale — no brittle bolt-ons that break the first time volume spikes.
Design that doesn't read generated
A distinctive storefront that signals a real brand, not a marketplace theme — because at your volume, looking like everyone else on the category page is a conversion problem, not just an aesthetic one.
PROOF
Proof, not themes.
Concepto Interiors took a category that normally depends on showroom visits and moved it online — 300+ finishes browsable, a video consult path, and deposit-as-commitment turned into the conversion anchor. Zinodeck sells a premium material where shoppers compare look, cost, and installation risk before they inquire, so we made a cost calculator and installer-matching the conversion engines instead of leaving the catalog to do all the work. Both are commerce-logic builds — buying paths engineered around how the customer actually decides — not theme installs.

FAQ
Common questions.
Are you a Shopify Plus agency?
Yes. We're a Shopify Partner focused on replatforming and CRO for brands already doing volume — the work is redesigning, migrating, and conversion-optimizing stores at scale, with the ERP, 3PL, and subscription wiring that comes with it.
Do you set up a store for a brand-new business?
Honestly, no — and we'll say so. If you're launching your first store on a tight budget, an off-the-shelf Shopify theme is the right, faster call, and paying agency rates for it would be a waste. We're built for brands where a basis point of conversion is real money and the constraint is a replatform, a checkout, or a CRO ceiling.
Can you replatform us without losing SEO or revenue?
Yes — that's the point of doing it properly. We map redirects, preserve URL structure, hold rankings, and stage the migration to Shopify Plus so revenue continues through the switch instead of dropping on launch day. Protecting the revenue you already have is the first job of a replatform, not an afterthought.
Can you wire ERP, 3PL, and subscriptions into the store?
Yes. Inventory and fulfilment (ERP, 3PL), subscription billing, and your email platform get wired into the build so operations and lifecycle revenue survive scale. The value in an ecommerce site lives between the systems, so that integration work is core scope, not an add-on.
How much does a Shopify Plus website cost?
Our public floors are a Studio Sprint from $8k for a focused build or CRO engagement, and the Full Studio from $24k for a complete store and brand system. A full replatform scales with catalog depth and the number of integrations. The current floors are at /pricing.
Could we just build this on an AI website builder?
For a simple storefront, maybe. But a checkout tuned for revenue, a replatform that protects SEO, ERP and 3PL integrations that hold at scale, and a brand that doesn't read as generated are exactly where AI builders stop. We lay out the honest trade-off at /compare/ai-website-builder-vs-web-design-agency.
How long does an ecommerce build or replatform take?
A focused Studio Sprint — a CRO pass or a contained rebuild — targets a 14-day ship. A full Shopify Plus replatform with catalog migration and integrations runs longer, depending on product data volume and how many systems have to be wired in.
