Why Differenz System

We Build Shopify Stores That Are Built to Sell, Not Just to Look Good

Any developer can install a Shopify theme. We build stores where the design, speed, and checkout flow all work together to turn more visitors into customers.

Design That Matches Your Brand

We do not use off-the-shelf templates unchanged. We design or customize themes specifically for your brand, products, and customers so your store looks and feels like yours from the first click.

Fast Stores That Do Not Lose Customers

A one-second delay in load time can cut conversions by 7%. We build and optimize Shopify stores for Core Web Vitals so your pages load fast on every device, especially mobile where most shoppers are coming from.

Checkout Built to Convert

Most stores lose customers at checkout. We optimize the cart and checkout experience to reduce friction, add trust signals at the right moments, and make it as easy as possible for someone to finish their purchase.

Migrations with Zero Data Loss

When you move from WooCommerce or BigCommerce to Shopify, we migrate every product, customer record, order, and URL with SEO-safe redirects so you do not lose traffic or search rankings during the switch.

Integrations That Keep Everything in Sync

We connect Shopify to your ERP, CRM, accounting software, email marketing platform, and payment tools so your inventory, orders, and customer data stay accurate across every system automatically.

SEO That Brings the Right Visitors

We configure Shopify's SEO settings correctly from the start β€” URL structure, meta tags, schema markup, sitemap, canonical tags, and page speed β€” so your store ranks for the searches your customers are actually making.

Our Shopify Services

Everything We Do to Design, Build, and Maintain Your Webflow Site

From a brand new site to a full platform migration or a redesign of an existing Webflow project, we handle every part of the work.

New Shopify Store Setup

Start Here

Starting a new Shopify store the right way means more than clicking a few buttons and adding products. We set up your entire store from scratch, connect your domain, configure payment and shipping, add your products correctly, and make sure the store looks great and works properly before it goes live.

  • Domain connection and Shopify account setup
  • Theme selection, installation, and customization for your brand
  • Product catalog setup with variants, images, and descriptions
  • Payment gateway configuration (Shopify Payments, Stripe, PayPal)
  • Shipping zones, rates, and carrier connections configured correctly
  • Tax settings, legal pages, and store policies set up and ready

Custom Shopify Theme Design and Development

Most Requested

Your Shopify theme is what customers see and feel when they land on your store. We design and build custom themes or heavily customize existing ones so your store looks like a premium brand, works perfectly on every device, and loads fast enough to keep shoppers engaged.

  • Custom theme design starting from your brand guidelines and target audience
  • Fully responsive design that looks and works well on mobile, tablet, and desktop
  • Custom homepage, collection, and product page layouts
  • Custom sections and blocks your team can edit without touching code
  • Performance optimization baked in β€” fast images, minimal code, clean structure
  • Accessibility standards followed so all customers can use your store

Platform Migration to Shopify

Zero Data Loss

Moving from WooCommerce BigCommerce, or any other platform to Shopify is not just a data copy. Done wrong, you lose orders, customer history, rankings, and traffic. We plan and execute the migration carefully so everything arrives intact and your store keeps ranking and selling from day one.

  • Products, variants, images, and inventory moved with no data loss
  • Customer accounts and order history transferred completely
  • 301 redirects set up for every old URL so you keep your SEO rankings
  • Old platform metadata and SEO data mapped to Shopify correctly
  • Full testing before cutover so nothing breaks when you go live
  • Post-migration monitoring to catch any traffic or ranking drops early

Shopify Plus Development

Enterprise

Shopify Plus is built for high-volume brands that need more than what standard Shopify provides. We build Shopify Plus stores with custom checkout experiences, B2B wholesale functionality, Shopify Flow automation, multi-store setups, and advanced integrations that regular Shopify cannot handle.

  • Custom checkout UI using Shopify Checkout Extensibility
  • B2B wholesale with customer-specific pricing and catalogs
  • Shopify Flow automation for order management, tagging, and fulfillment
  • Multi-store and multi-market setup for international selling
  • Headless commerce builds using Shopify's Hydrogen framework
  • Advanced API integrations with ERPs, 3PLs, and enterprise systems

App Integration and Custom App Development

Extend Your Store

Shopify's App Store has thousands of apps, but they are not always the right fit. We install and configure the best apps for your needs, and when no existing app does what you need, we build a custom private app using the Shopify API so your store works exactly the way your business requires.

  • App selection, installation, and configuration for your specific needs
  • ERP connections (SAP, NetSuite, Odoo) for inventory and order sync
  • CRM integrations with Salesforce, HubSpot, or Zoho
  • Email marketing connections (Klaviyo, Mailchimp, Omnisend)
  • Custom private apps built with the latest Shopify API for unique requirements
  • Subscription and loyalty program integrations configured and tested

Speed, SEO, and Conversion Optimization

Grow Revenue

If your Shopify store is already live but not performing as well as it should, we diagnose exactly what is slowing it down or losing customers and fix it. We improve page speed, Core Web Vitals, product page layout, checkout flow, and SEO configuration so your store ranks better and converts more.

  • Page speed audit and improvements (image compression, code cleanup, lazy loading)
  • Core Web Vitals improvements for Google ranking signals
  • Product page optimization β€” layout, trust signals, copy, and image quality
  • Cart and checkout flow review and friction removal
  • SEO technical setup β€” meta tags, schema, canonical tags, sitemap, hreflang
  • Mobile experience audit and improvements for on-the-go shoppers

Ongoing Maintenance and Support

Long-Term

A Shopify store needs regular attention to stay fast, secure, and working properly as Shopify updates its platform and your business grows. We provide ongoing maintenance so you always have someone to call when something breaks, something changes, or you want to add something new.

  • Regular app and theme updates applied and tested before going live
  • Performance monitoring and speed checks every month
  • Bug fixes and broken functionality resolved quickly
  • New product pages, collection pages, and landing pages added as needed
  • Holiday and sale season preparation β€” checking load capacity and checkout flow
  • Priority support so you are never stuck waiting when something urgent comes up

Our Process

How We Build Your Shopify Store from Start to Launch

A clear six-step process so you always know what we are working on, what comes next, and when your store goes live.

1

Discovery and Planning

We learn about your brand, your products, your customers, and what you want the store to do. We review your current platform if you are migrating and document everything before any design or development begins.

2

Design Wireframes and Mockups

We design the key pages of your store before writing a single line of code. You review and approve how the homepage, product page, and checkout flow will look and work before we build anything.

3

Theme Development

We build your approved design into a fully functional Shopify theme. Every page is built with clean, fast code and tested for mobile responsiveness, browser compatibility, and page speed as we go.

4

Content, Products, and Apps

We add your products, configure your apps, set up payment and shipping, write any missing content, and connect your store to the tools you use. Everything is in place before we call it ready for review.

5

Testing and Quality Checks

We test every page, every product, every form, and the full checkout flow on desktop and mobile across multiple browsers. We test speed, SEO, and accessibility. You review the complete store before it goes live.

6

Launch and Ongoing Support

We launch your store during a low-traffic window and monitor closely after go-live. We fix anything that comes up quickly and stay available for maintenance, updates, and improvements as your store grows.

Common Questions

Questions People Ask Before Starting a Shopify Project

What Shopify services does Differenz System provide?

We provide new Shopify store setup, custom theme design and development, platform migration from WooCommerce BigCommerce, and other platforms, Shopify Plus builds, app integration, custom private app development, speed and conversion optimization, SEO configuration, and ongoing maintenance and support.

How long does it take to build a Shopify store?

A new Shopify store using a customized existing theme typically takes 3 to 6 weeks to design, build, and launch. A fully custom theme built from scratch takes 6 to 10 weeks. Shopify Plus builds and complex migrations can take 8 to 16 weeks depending on scope. We share a detailed timeline before any work begins so you know exactly when to expect your store to go live.

Can you migrate our store from WooCommerce to Shopify without losing data or rankings?

Yes. We migrate stores from WooCommerce BigCommerce, Wix, Squarespace, and custom platforms to Shopify. We move your products, customer records, order history, and all URLs with SEO-safe 301 redirects so your search rankings are protected. We test everything before cutover and monitor traffic in the weeks after go-live to catch any drops early.

What is Shopify Plus and do I need it?

Shopify Plus is Shopify's enterprise plan designed for high-volume stores, typically those doing more than $1 million per year in revenue. It gives you more control over your checkout, B2B wholesale selling tools, Shopify Flow automation, multi-store management, and a dedicated Shopify merchant success manager. We will tell you during our first conversation whether Shopify Plus is the right fit or whether a standard Shopify plan handles everything you need.

Can you improve the speed and conversion rate of our existing Shopify store?

Yes. We audit your store's page speed, Core Web Vitals, product page layout, cart and checkout experience, and mobile performance. We then make targeted improvements that reduce load time, remove friction from the buying process, and help more visitors complete their purchase. We show you exactly what we are changing and why before we make any changes.

Do you build custom Shopify apps?

Yes. When no existing app from the Shopify App Store meets your specific requirements, we build custom private apps using the Shopify API. These can handle things like custom pricing rules, unique loyalty programs, specialized inventory automation, ERP connections, or any workflow that does not fit a standard app. Every custom app is built to Shopify's latest API standards and tested thoroughly before it connects to your live store.

Do you provide ongoing support after the Shopify store is launched?

Yes. We offer ongoing maintenance and support plans after launch. This covers app and theme updates, bug fixes, performance monitoring, new page and feature additions, and priority support when something breaks or needs to change quickly. Many of our clients stay with us as their long-term Shopify partner as their stores grow.
