Shopify developmentbuilt to convert —not just to launch.
Custom themes, full builds, and the integrations that hold a store together — from a senior team that's shipped 80+ Shopify stores in six years. You get a store built to convert, and a plan you can actually read.

When your Shopify store stops pulling its weight
Most Shopify stores don't fail loudly. They plateau. Traffic holds, ad spend climbs, and the conversion rate sits flat for months while you stare at the analytics wondering what changed. Usually nothing changed — the store was never built to convert in the first place.
It's a familiar pattern. You launched on a premium theme to move fast. Then you bolted on apps — reviews, upsells, a popup, a loyalty widget — each one adding scripts that slow the page down. The store loads in four seconds on mobile. The product pages look like every other brand on the same theme. Checkout leaks customers you paid to acquire. And every small change means wrestling with theme code that was never built to be extended.
That's the store most DTC founders bring us. Not broken — just tired, slow, and generic, quietly capping how much revenue the same traffic could produce.
Custom Shopify development fixes the foundation. Not a fresh coat of paint on the same theme, but a store architected around how your customers actually buy: fast on mobile, clean in the cart, built so the next change takes hours instead of a sprint. We've shipped 80+ of these. The brands that move from a templated theme to a purpose-built store usually aren't chasing more traffic — they're trying to make the traffic they already pay for finally convert.
What a Shopify development engagement includes
No two builds are identical, but a typical custom Shopify engagement with us covers all of this:
Discovery & conversion audit
Before any design, we map your funnel, your customers, and where the current store leaks revenue. You get a documented plan — what we're building and why — not a vague creative brief.
Custom theme build
A theme built for your brand from the structure up, not a marketplace template reskinned. Clean, extensible Liquid your team (or ours) can change later without breaking things.
App & API integrations
Reviews, subscriptions, loyalty, ERP, 3PL, email and SMS — wired in deliberately. We cut the app sprawl that bloats most stores and keep only what earns its place on the page.
Performance optimization
We build for Core Web Vitals and real mobile load times, because speed is both a ranking factor and a conversion factor. Most rebuilds ship meaningfully faster than the theme they replace.
Conversion-focused product & checkout pages
Product pages, cart, and checkout structured around how people actually decide and buy — the pages where revenue is won or lost.
Analytics & tracking setup
GA4, server-side events where they matter, and clean conversion tracking from launch day — so you can see what works instead of guessing.
CMS training & handover
We hand the store over with documentation and a walkthrough, so your team can run merchandising and content without filing a ticket for every edit.
30 days of post-launch support
Every build includes 30 days of post-launch care for fixes and tuning. Most issues surface in the first weeks of real traffic — we're there for them.
How a build runs
Audit & discovery
We dig into your analytics, your customers, and your current store. You come out with a fixed-scope plan: what we're building, what it costs, and what it's expected to do.
Design & architecture
Information architecture and design in Figma, reviewed with you before a line of code. We agree the conversion logic on screen first — it is cheaper to change a wireframe than a built page.
Build & test
Design and engineering in weekly increments. You see real, working pages every week — not a deck at the end. Then QA across devices, browsers, and edge cases before anything goes live.
Launch & optimize
Migration, redirects, schema, analytics, and a launch-day checklist. Then 30 days of polish, with the option to move into ongoing CRO and growth work.
What a Shopify build costs
Straight answer, because most agencies dodge it: a custom Shopify build with us starts at $8,000. Most projects land between $12,000 and $25,000. Complex builds — multi-region, B2B, headless, or heavy custom app work — go higher, and we'll tell you that before you're invested.
What moves the number:
- Integration count: every system you connect (ERP, 3PL, subscriptions, loyalty, custom APIs) adds scope.
- Content volume: a 30-product catalog is a different build from 3,000 SKUs with complex variants.
- Custom app needs: when an off-the-shelf app can't do the job, we build it — that's planned scope, not a surprise invoice.
- A headless layer: a Next.js front end for performance-critical stores is a bigger investment than a Liquid theme, and not every store needs one.
What's not included in a build price: ongoing monthly retainers, paid media spend, and content production like photography and copywriting. We'll point you to who's good at those, but we don't pad a build with them.
We quote fixed scope after a discovery call, so the number you approve is the number you pay — no hourly meter, no "phase two" you didn't agree to. If your budget is under $8K, we'll say so honestly: you'll get more from a well-chosen premium theme set up properly than from a half-funded custom build.

Who this is for
This is built for DTC brands doing roughly $250K to $5M a year that have outgrown their theme. Founders rebuilding a store that's gone stale. Brands launching a second line or a separate store. Teams cleaning up after a freelancer build that fell apart the moment it got complex. If your store is the main way you make money and it isn't converting like it should, you're who we build for.
Who it's not for, honestly:
- Pre-revenue ideas. If you haven't validated demand, a custom build is the wrong place to spend money — launch lean on a good theme first.
- Sub-$5K budgets. Below that, a premium theme set up well will serve you better than a custom build we'd have to cut corners on.
- Projects that need a 20-person team and a year-long roadmap. We're a senior team that ships; we're not built to staff an enterprise program of that size.
We'd rather tell you we're not a fit on the first call than take a project that was always going to disappoint.

Relevant work
A few of the stores we’ve built. Browse the full portfolio for more.
Most custom builds run six to eleven weeks from kickoff to launch, depending on the number of templates, integrations, and how ready your content and assets are. We work in weekly increments, so you see live pages throughout — not a single reveal at the end.
Yes. If you have brand guidelines, a design system, or photography, we build to them. If you don't, we can handle design from scratch or work alongside your designer. We won't force a rebrand you didn't ask for.
Both. We use proven apps where they do the job well and keep the store lean. When an off-the-shelf app can't do what you need — or its scripts are dragging the page down — we build a custom one instead. We've shipped apps with 60K+ combined installs, so this is core work for us, not a stretch.
We handle migrations from WooCommerce, Magento, BigCommerce, Wix, and custom platforms — product, customer, and order data, URL mapping, and 301 redirects so you don't lose the SEO you've built. Migration scope is quoted as part of the build.
Every build includes 30 days of post-launch care for fixes and tuning — most issues surface in the first weeks of real traffic. After that, you can move to an ongoing retainer or just call us when you need us.
Yes. A lot of clients move from the build into ongoing CRO, performance marketing, or feature work. There's no obligation — the build stands on its own — but the door's open if you want one team that already knows your store.
