Shopify Plus is the platform built for what comes next. We are a certified Shopify Plus development agency. We build, migrate, and scale Plus stores for brands that need it done right the first time.

Shopify Plus development: enterprise ecommerce store built for scale

The World's Fastest-Growing Brands Trust Ecomm Wizards

200+ Shopify Plus store development projects completed. $900M+ in client revenue generated. From DTC challengers to global enterprise brands.

Why Brands Choose Shopify Plus

Standard Shopify locks you out of the features that drive growth past $2M. Here is what Shopify Plus opens up and what it actually delivers.

Checkout Extensibility

Add upsells, gift messages, loyalty redemption, custom fields, and branded elements directly inside the Shopify checkout via native Extensions. No redirects. No third-party replacements.

Real result: Clients see an average 18% higher AOV once checkout upsells run via native Extensions.

Shopify Flow Automation

Build automated workflows triggered by orders, customer actions, and inventory changes. Routing, tagging, alerts, and marketing triggers run without your team touching them.

Real result: Operations teams typically save 12+ hours per week once Flow replaces their manual workflows.

Native B2B Commerce

Company profiles, segment-specific pricing, net payment terms, and self-service wholesale portals built into the platform. B2B and DTC run from one admin with no separate tools needed.

Real result: Henchman's self-serve B2B portal cut their sales team's manual order workload by 40%.

Shopify Functions

Write custom discount logic, cart rules, payment methods, and shipping rates at the platform level. Volume discounts, tiered pricing, and BOGO rules that no app can replicate.

Real result: A single custom Shopify Function typically replaces three to four expensive third-party discount apps.

Shopify Markets

Sell in multiple countries, currencies, and languages from one storefront. Localized pricing, duty inclusion, domain routing, and language switching without separate stores.

Real result: Dryrobe expanded into Germany and added a second currency with zero additional store overhead.

Enterprise API Access

10x higher API rate limits than standard Shopify. Large catalogs, real-time ERP syncs, high-volume orders, and multi-warehouse inventory run without rate limit failures.

Real result: Everlast syncs 150K+ SKUs with their ERP in real time without rate limit errors.

We migrate from Magento, WooCommerce, BigCommerce, and standard Shopify to Plus with full data transfer, redirect mapping, SEO preservation, and a rollback plan. Cutover happens in a low-traffic window.

We build native Checkout Extensions: upsells, gift messages, loyalty redemption, and branded UI inside the Shopify Plus checkout. No redirects, no third-party replacements. Higher AOV without added friction.

We build headless Shopify Plus stores via the Storefront API when performance or brand requirements go beyond standard themes. Shopify handles commerce; your front end is built exactly to spec.

We configure Shopify Plus B2B: company profiles, segment pricing, net terms, and self-service wholesale portals. Trade buyers order without calling your team. B2B and DTC run from one admin.

We build private Shopify apps, admin extensions, and API-driven features when the app store falls short. Custom pricing logic, operational workflows, and buyer experiences built directly into the platform.

We connect Shopify Plus to NetSuite, SAP, HubSpot, Salesforce, Brightpearl, and custom 3PL systems. Real bidirectional integrations that sync inventory, orders, and customer data at scale.

We audit and rebuild Shopify Plus stores with app bloat or Core Web Vitals problems. Target: 90+ Lighthouse scores. Faster stores rank higher and convert better.

Their
Shopify Plus Development Agency

We have built 200+ Shopify Plus stores and helped clients generate over $900M in revenue. Here is what makes us
the right Plus development agency for brands that cannot afford to get this wrong:

Certified Shopify Plus Partner

Accredited Shopify Plus partner with direct access to Plus support and early feature access. You get a team that knows the platform from the inside, not an agency learning on your project.

Checkout-First Methodology

Your Shopify Plus checkout is your highest-converting page. We define the checkout experience first, then build backwards. Clients see an average 18% lift in AOV from checkout work alone.

B2B Commerce Built Right

We set up Shopify Plus B2B properly: company accounts, segment pricing, payment terms, and wholesale portals. Your trade buyers self-serve. B2B and DTC run on one platform.

Enterprise Integration Depth

We connect Shopify Plus to NetSuite, SAP, HubSpot, Salesforce, and custom 3PL systems. Real API integrations that sync reliably at scale, not off-the-shelf connectors that break under volume.

90-Day Post-Launch Window

Every project includes a 90-day post-launch window. We monitor your Plus store, fix anything that surfaces, and keep building as live traffic grows. You are not on your own after go-live.

Proven at Enterprise Scale

$900M+ in client revenue. Everlast, BARK, Dryrobe, Wild, and more. Real enterprise brands on Shopify Plus with results you can read in their case studies, not claims you take on faith.

Every Shopify Plus project passes full QA before a single customer sees it. Built to Plus standards, scoped for your growth, and supported after go-live.

Frequently Asked Questions

  • Cost depends on scope: what you need built, how many integrations are involved, and whether it is a full store build or targeted enhancements. A custom checkout extension or Flow automation build starts from £3,000. A full Shopify Plus store build or migration from Magento or WooCommerce starts from £15,000. We work on fixed-price quotes, not hourly rates. Send us your requirements and we will return a detailed estimate within 24 hours.

  • Targeted Plus work, such as a custom checkout extension or Flow automation build, takes 2 to 3 weeks. A full Shopify Plus store build takes 6 to 10 weeks. A migration from Magento, WooCommerce, or BigCommerce takes 8 to 14 weeks depending on catalog size, integration complexity, and B2B requirements. Every project starts with a fixed timeline you approve before we write a single line of code.

  • A Shopify Plus project covers frontend development, React-based checkout extensions, API integrations, Shopify Flow automation, B2B configuration, and load testing. A freelancer typically covers one or two of those areas. When you hire a Shopify Plus development agency, you get all of them under one brief, one timeline, and one point of accountability. Our Shopify Plus developers have completed 200+ Plus projects. You are not our first.

  • Shopify Plus makes sense when you are generating over $1M annually and hitting the limits of standard Shopify: a checkout you cannot customize, automations that require manual work, API rate limits causing sync failures, or B2B buyers you manage outside the platform. For most brands at that revenue level, the upgrade pays for itself through checkout conversion improvements and automation savings alone.

  • Yes. We migrate brands from Magento, WooCommerce, BigCommerce, and standard Shopify to Shopify Plus with full data transfer, URL redirect mapping, SEO preservation, and integration rebuilds. Every migration has a rollback plan. The cutover is planned for a low-traffic window. The new store goes live with zero downtime and outperforms what you left behind from day one.

  • On Shopify Plus, the checkout is fully customizable through native Checkout Extensions. We build extensions that add upsells, cross-sells, gift messages, custom input fields, loyalty reward redemption, branded UI elements, and payment method logic directly inside the Shopify checkout. No third-party replacements, no redirects. Everything runs inside the native flow.

  • Shopify Plus includes native B2B features that standard Shopify does not have: company profiles, customer-specific pricing by segment, net payment terms, draft orders, and self-service wholesale portals. You manage B2B and DTC from one admin without separate platforms or apps filling gaps. If your brand has trade buyers, wholesale accounts, or volume pricing requirements, Plus is the right platform.

  • We carry over all metadata, canonical tags, URL structure, and redirect logic as part of every migration. For URL structure changes, we map every old URL to a new destination with 301 redirects before launch. We submit updated sitemaps immediately after go-live. The improved Core Web Vitals on the new Plus store typically push rankings up, not down, within 30 to 60 days.

  • Shopify Plus costs $2,500 per month, or 0.25% of monthly revenue, whichever is higher, up to $20,000 per month on the variable-fee tier. This is the Shopify platform fee, separate from any development work. For most brands generating over $2M annually, Plus pays for itself through checkout conversion improvements, automation efficiency savings, and reduced third-party app costs.

  • Shopify Plus is the enterprise tier. It gives you full checkout customization through Checkout Extensions, Shopify Flow for complex automation, native B2B tools including company profiles and segment pricing, higher API rate limits, and access to Shopify Launchpad. Standard Shopify locks the checkout and limits automation. Plus removes those limits for brands that have outgrown the standard platform.
