Shopify Plus Development
Shopify Plus is a different job than Shopify
Upgrading to Shopify Plus gives you features standard plans do not: checkout customization through extensions, custom Shopify Functions for discount, shipping and payment logic, native B2B, expansion stores, Launchpad for scheduled sales and higher API limits. But the plan alone changes nothing. Many brands pay for Plus for a year and still run the same theme, the same apps and the same manual processes they had before.
Codefreex treats Plus as an engineering platform, not a pricing tier. We audit what you are paying for, rebuild legacy Shopify Scripts and checkout.liquid edits as Functions and checkout extensions, set up B2B and international markets properly, and automate the manual work your team repeats every day. You keep one accountable team across development, performance and conversion work, backed by 540+ projects delivered.
What you get
Shopify Plus capabilities we build
We focus on the Plus features that change revenue and operations, and we build them to survive Shopify’s platform updates.
Checkout Extensibility Builds
Custom checkout UI extensions for upsells, delivery instructions, loyalty and trust content, plus branding through the Checkout Branding API, so your checkout matches your store and keeps working through Shopify updates.
Shopify Functions Development
Custom discount, shipping, payment and cart validation logic written as Shopify Functions, replacing legacy Shopify Scripts with rules that run on Shopify’s own infrastructure at checkout speed.
B2B and Wholesale Setup
Company accounts, customer-specific catalogs and price lists, payment terms, quantity rules and a wholesale portal that runs alongside your DTC store on a single Shopify Plus account.
Multi-Market and Expansion Stores
Shopify Markets, local currencies, translated content, regional domains and expansion stores configured so each region gets the right prices, payment methods and tax handling.
Flow and Launchpad Automation
Shopify Flow workflows for tagging, fraud review, inventory alerts and fulfillment routing, plus Launchpad schedules for product drops, theme swaps and sale pricing that go live on time.
Replatforming to Shopify Plus
Migrations from Magento, WooCommerce or custom platforms with products, customers, order history and URL redirects mapped carefully, so search rankings are protected through the move.
Platforms and tools we work with
How we work
How a Shopify Plus engagement runs
Clear phases, a named owner for every deliverable and weekly progress you can see.
Plus audit
We review your theme, apps, checkout, scripts and integrations, then list which Plus features you are not using and which apps can be replaced.
Roadmap and solution design
We rank opportunities by revenue impact and effort, and write technical specs for each extension, Function or integration so your team knows exactly what is being built.
Build on a development store
Work happens in development stores and preview themes, with code in Git and QA on real devices, so your live store keeps selling while we build.
Release and optimize
We release in planned windows outside your peak hours, monitor conversion and errors closely, and continue with a monthly roadmap of CRO and feature work.
Who it is for
Brands that get the most from Plus
High-volume DTC brands
Brands with heavy traffic and frequent launches that need custom checkout logic, scheduled drops and automation to keep operations calm during peaks.
Wholesale and B2B sellers
Manufacturers and distributors moving trade customers off email orders and spreadsheets onto company accounts with negotiated pricing and payment terms.
International retailers
Brands selling in several countries that need local currencies, languages, duties and payment methods managed without running separate disconnected stores.
Brands leaving Magento
Merchants tired of hosting, patching and extension conflicts who want enterprise features on a managed platform without losing SEO or order history.

FAQ
Shopify Plus Development: FAQs
Straight answers to what buyers ask us most. Still unsure? Book a free 30-minute call.
Is Shopify Plus worth it for my business?
Shopify Plus is usually worth it when you need features standard plans lack, such as checkout extensions, native B2B, custom Shopify Functions, expansion stores or higher API limits. For many brands, the decision comes down to order volume and operational complexity. Codefreex reviews your revenue, apps and processes and tells you honestly whether Plus will pay for itself or whether Advanced Shopify is enough.
How much does Shopify Plus development cost?
Shopify Plus development cost depends on what you need built. A single checkout extension or Shopify Function is a small project, while a replatform with B2B and several markets is a much larger one. The Plus subscription itself is billed by Shopify, separate from development work. Codefreex starts with a Plus audit, then sends a detailed quote tied to a clear, written scope.
What is the difference between Shopify and Shopify Plus?
Shopify Plus is Shopify’s enterprise plan, built on the same platform with extra control and capacity. Plus adds checkout customization through extensions, custom Shopify Functions, native B2B, expansion stores, Launchpad, higher API rate limits and priority support from Shopify. Standard plans suit most growing stores, while Plus suits brands where checkout logic, wholesale or multiple regions drive revenue.
Can you rebuild our old checkout.liquid and Shopify Scripts logic?
Yes. Shopify has deprecated both checkout.liquid and Shopify Scripts, so any logic that lived there must be rebuilt with checkout UI extensions and Shopify Functions. Codefreex audits every script and checkout edit you relied on, rebuilds the ones that still matter in the supported format and tests them against your real discount, shipping and payment scenarios before release.
Do you build B2B stores on Shopify Plus?
Yes. Codefreex sets up B2B on Shopify Plus with company profiles, multiple buyers per company, customer-specific catalogs and price lists, payment terms, volume pricing and quantity rules. We can run wholesale from the same store as your DTC business or from a dedicated expansion store, and connect it to your ERP or CRM so orders and accounts stay in sync.
Will our live store be affected during Shopify Plus development?
No. Codefreex builds and tests Plus features in development stores and unpublished preview themes, so your live store keeps taking orders while we work. Checkout extensions and Functions ship as app versions that can be rolled back, and we schedule releases outside your busiest hours with monitoring in place.
Is Codefreex a Shopify Plus partner?
Yes. Codefreex is a Shopify Partner and holds a Shopify Plus partner badge, alongside Klaviyo, Google and Meta partnerships that matter for Plus brands. Our in-house team of 23+ certified professionals brings 9+ years of industry experience, and we are a Top Rated agency on Upwork with reviews on Clutch.
