Shopify stores built to convert, not just launch.
End-to-end Shopify development services covering strategy, design, custom code, and apps. We build stores that load fast, rank well, and turn visitors into orders, with a fixed price you approve before we write a line of code.
What are Shopify development services?
Shopify development services cover the technical work behind building, customizing, and maintaining a store on Shopify: strategy and UX design, custom theme development, app development, third-party integrations, and Shopify Plus builds for larger merchants. It spans everything from a theme-based store for a new brand to a fully custom build with bespoke checkout logic for an enterprise catalog.
At TheShopNinjas, we’ve built this into a repeatable process after shipping 500+ Shopify stores across WooCommerce migrations, ground-up builds, and Shopify Plus projects. The right scope depends on your catalog, your customers, and where the store needs to grow next, so we scope every engagement before quoting instead of selling a one-size package.
Every Shopify build, handled.
Pick the service that matches where you are today. A new store, a redesign, or a Shopify Plus build all start with the same scoping call.
Shopify Website Development
A professional storefront built on Shopify’s core theme architecture, tailored to your brand and ready to scale from day one.
Shopify Ecommerce Website
A complete online store built around your catalog, from product architecture through checkout, engineered to turn browsers into buyers.
Custom Shopify Development
Custom code for the parts Shopify’s defaults can’t handle: bespoke sections, custom Liquid, and app-free functionality built to spec.
Shopify App Development
Public or private Shopify apps built on current APIs, from internal tools that save your team hours to apps sold on the App Store.
Shopify Theme Development
A custom Online Store 2.0 theme built section by section in Liquid, so your team controls every page without touching code.
Shopify Plus Development
Enterprise-grade builds for high-volume merchants: custom checkout with Shopify Functions, multi-store, B2B, and ERP-level integrations.
Not sure which one fits your store? We’ll tell you on the call, not upsell you into one.
Talk to a development leadA full build, not a theme install.
Every Shopify development project we run includes these six workstreams end-to-end. No line items get sold back to you as upgrades.
Discovery & strategy
We start from your catalog, customers, and goals, not a template. Every build starts with a scope document, not a guess.
- Competitor & catalog audit
- Information architecture
- Tech stack & app plan
- Conversion benchmarks set
UX & UI design
Figma mockups tailored to your brand and your customer’s path to checkout, not a reskinned theme demo.
- Custom Figma design
- Mobile-first layouts
- Brand system applied
- Stakeholder review rounds
Theme & app development
Section-by-section Online Store 2.0 development, plus custom apps and Liquid where the defaults run out.
- OS 2.0 theme sections
- Custom Liquid & metafields
- Public or private apps
- Shopify Functions (Plus)
Third-party integrations
Every tool your business already runs on gets a working connection before launch, not a support ticket after.
- CRM & email marketing
- ERP & inventory systems
- Subscriptions & loyalty
- Multi-channel (Amazon, TikTok, etc.)
Performance & CRO
Speed and conversion get engineered in from the first sprint, not bolted on with an app after the store already feels slow.
- Core Web Vitals optimization
- Checkout flow review
- A/B-test-ready structure
- Analytics & tracking setup
Launch & post-launch support
A launch isn’t the finish line for us. We stay hands-on for 30 days and train your team to run the store confidently.
- QA across devices & browsers
- 30-day post-launch support
- Admin training for your team
- Optimization roadmap
Six phases from kickoff to live.
Every Shopify development project runs through the same six phases. You know what’s happening, when, and what’s expected from your team.
Built to perform. Or we fix it free.
If your store launches slower than agreed, misses its Core Web Vitals targets, or breaks on a supported device, we fix it at no charge. We don’t hand off a build and disappear.
What you don’t pay for if it goes wrong.
A slow, unconverting store costs you every day it’s live. Here’s what we put in writing before you sign anything:
- Fixed-price contract. No hourly billing, no scope creep invoices.
- Performance benchmark. Core Web Vitals targets agreed before we start building.
- Revision rounds included. Design and QA feedback built into the price, not billed as extras.
- 30-day post-launch coverage. Bug fixes and adjustments included, not billed extra.
- Ownership guarantee. You own the code, the theme, and every asset we build. No lock-in.
Page builders, cheap freelancers, or done right.
The three real options when you’re building on Shopify, and where each one leaves you 90 days later.
The team you want building your store.
A specialist Shopify agency, not a generalist dev shop that also does Shopify sometimes.
Shopify-only specialists
Every developer on your build has shipped Online Store 2.0 sections and Shopify apps dozens of times over. We don’t learn Shopify on your dollar.
500+ stores builtDesign and code, one team
One team stays accountable for how the store looks and how it performs, instead of a designer and a developer pointing fingers at each other.
