Enterprise shopify plus developers who deliver builds that ship on schedule and to spec
Custom checkout extensions. Headless storefronts. B2B wholesale channels. Enterprise resource planning and customer relationship management integrations. Redefine delivers every component of your Shopify Plus build on a fixed timeline, no scope creep, no open-ended delivery estimates.
Most enterprise Shopify Plus projects run over budget and past deadline
We engaged three agencies before Redefine. All three over-promised timelines and under-delivered on Shopify Plus features. The checkout extensibility we were sold in the pitch was handed off to a junior contractor six months in.
From signed brief to live Shopify Plus store in 12 weeks
A fixed five-phase program turns vague Plus ambitions into a live, fully operational store, checkout extensibility, B2B channel, integrations, and all. Each phase ends with a deliverable you approve before the next begins.
Requirements, tech stack selection, Plus feature roadmap, integration mapping, and timeline confirmation, all documented before development starts.
Design tokens, component library, checkout user interface extensions wireframed and approved by your team before a single production component ships.
Checkout extensions, Shopify Functions, B2B channel, Shopify Flow automation, and all enterprise resource planning or customer relationship management integrations built across five focused sprints.
Full device and browser quality assurance, load testing, checkout flow validation, and integration smoke tests. Your team runs user acceptance testing in the staging environment before any code moves to production.
Zero-downtime launch execution. Post-launch monitoring for 48 hours. Full technical handover documentation and team training on every Plus capability deployed.
The Shopify Plus development stack we build for every enterprise program
Every Redefine Plus build activates the full enterprise technology surface, not just the storefront theme. Click any node to see how each component connects to your operations.
Organization admin, multi-store setup, user access, and custom domain configuration for all markets. The foundation everything else connects to.
React components rendering in the checkout: upsell blocks, trust badges, custom form fields, loyalty point display, and gift message inputs.
Server-side custom logic: tiered discount rules, custom shipping rate calculation, payment method filtering by order type or customer segment.
Company accounts, net payment terms, custom price lists per company, purchase approval workflows, and dedicated B2B storefront routing.
Workflow automations triggered by store events: customer tagging, fraud flagging, inventory reorders, B2B approval notifications, and loyalty tier updates.
Real-time data flows between Shopify Plus and your enterprise resource planning (inventory, orders, financials), customer relationship management (customer data, accounts), and warehouse management system (fulfillment routing).
Six Shopify Plus development capabilities delivered in every engagement
Not a menu of add-ons. Every Redefine Plus development program includes all six service lines, scoped to your specific catalog, workflow, and integration needs.
Custom Checkout Development
Checkout user interface extensions, post-purchase flows, and Shopify Functions built to your specification, upsells, trust signals, custom fields, and payment logic that survive every platform upgrade.

A complete B2B headless Shopify Plus build, delivered on schedule
An established B2B promotional products company serving complex catalogs, customer-specific pricing, and approval-based purchasing workflows.
The headless architecture now supports catalog scale, marketing initiatives, and future system enhancements without requiring a platform rebuild.
The new platform delivers faster performance, reliable live inventory, and a smoother B2B purchasing and approval experience. Catalog usability improved significantly, operational friction was reduced, and internal teams gained confidence in system accuracy.
What separates a shopify plus development company from a general agency
Most agencies build Shopify stores. Redefine builds Shopify Plus programs, activating every enterprise capability, integrating with your existing systems, and delivering on a fixed timeline your chief technology officer can hold us to.
Fixed 12-week delivery, in writing
Your delivery date is agreed before a single line of code is written. No open-ended timelines, no "it depends on scope" retainer billing. A fixed delivery commitment means your launch date is real, not aspirational.
Checkout extensibility expertise in-house
Checkout user interface extensions and Shopify Functions are complex. Most agencies hand them off to contractors or skip them entirely. Our in-house team builds and maintains checkout extensions directly, so your Plus capabilities ship with the store, not six months later.
Enterprise resource planning and customer relationship management integration, not a bolt-on
System integration is not an afterthought in our builds. We architect the integration layer during discovery, before development starts, so enterprise resource planning inventory, customer relationship management customer data, and warehouse management system fulfillment routing are live at launch, not added on month four.
One dedicated project engineer, not a rotating team
Your project engineer knows your catalog, your systems, and your edge cases from discovery through post-launch. No handoffs to juniors at sprint two. No account manager relaying messages between you and an offshore team you never meet.
Performance targets baked into the delivery spec
Largest Contentful Paint under 2 seconds on mobile. Cumulative Layout Shift under 0.1. Core Web Vitals in the "Good" range. These are not aspirational, they are confirmed in quality assurance before your store goes live. Performance is treated as a feature, not a post-launch cleanup task.
Full technical handover, not a GitHub zip
Post-launch documentation covers every custom component, integration mapping, Flow configuration, and Shopify Functions deployment. Your internal team or next partner can maintain and extend the codebase without reverse-engineering decisions made in week three.
Enterprise shopify development on Plus, answered
The questions operations leaders and chief technology officers ask before committing to a Shopify Plus development program.
Shopify Plus development programs range from $40,000 to $250,000 depending on scope: a standard theme build with checkout extensions sits at the lower end; a full headless build with multiple enterprise resource planning integrations, B2B channel, and Shopify Flow configuration sits at the higher end. We scope every program precisely and provide a fixed project price before any work begins.
Yes. We manage migrations from Magento 1 and 2, BigCommerce, WooCommerce, and custom-built platforms. Every migration includes a full data audit, search engine optimization equity preservation strategy, 301 redirect mapping, and a phased go-live plan. We target zero-downtime migrations with revenue continuity from day one of launch.
Our fixed timeline commitment is built on a precise discovery phase. If delay risk emerges during development due to factors within our control, we absorb the additional resource cost. If scope changes are requested by your team after discovery sign-off, we provide a clear change order with timeline and cost impact before any additional work is done.
Yes. We build headless storefronts using Shopify Hydrogen (React Router) for stores that require custom performance targets, multi-market rendering, or tightly controlled frontend architecture. Hydrogen adds complexity and development time compared to a theme build. We recommend it for stores where the performance or architectural requirements specifically justify the overhead, and advise against it when a well-optimized theme build would deliver the same outcome faster.
Every program includes 48-hour post-launch monitoring, a full technical handover package, and a documented handoff session with your internal team. Ongoing development support is available as a separate retainer engagement, scoped to your specific needs, so you only pay for what your team actually requires after launch. We do not bundle unnecessary maintenance retainers into the base project.
Your Shopify Plus development program starts with a scoped brief, not a sales call
Book a 30-minute discovery call. You describe the store, integrations, and Plus capabilities you need. Our shopify plus developers walk you through how a 12-week program would be structured for your specific build, including a rough scope and timeline before any commitment.
We will review your workflow and send a scoped proposal within 3 business days.
