Shopify Plus is the enterprise tier of Shopify — unlocking B2B wholesale, Checkout Extensibility, Shopify Flows, multi-store Organisation, and priority support. WebAnts is a London Shopify Plus agency building custom Plus stores for DTC and consumer brands, fashion and luxury retailers, and enterprise ecommerce operators.
Unlike standard Shopify, Shopify Plus gives you complete control over the checkout UI via Checkout Extensibility, native B2B catalog and price lists without third-party apps, and Shopify Flows for complex no-code automation. We configure the full Plus stack — from custom Liquid themes to headless Next.js frontends.
We handle Magento to Shopify Plus migrations, multi-store Organisation architecture, ReCharge subscription builds, and deep Klaviyo and Yotpo integrations. Flat written quote after a free 30-minute discovery call.
Why Shopify Plus
Six reasons enterprise brands choose Shopify Plus.
B2B native. Checkout you control. Automation without engineers. Shopify Plus combines enterprise features with the simplicity of a SaaS platform.
01
Checkout extensibility
Full control over your checkout UI with Shopify Plus Checkout Extensibility — custom blocks, upsells, and branding all the way through to the order confirmation page without touching checkout.liquid.
02
B2B catalogs and wholesale pricing
Shopify Plus includes native B2B functionality — company profiles, price lists, net payment terms, and purchase orders — all out of the box without expensive third-party apps or workarounds.
03
Shopify Flows for complex automation
Shopify Flows lets you automate complex workflows — tag high-value customers, trigger Klaviyo sequences, manage inventory alerts, and build multi-step logic — all without writing a single line of code.
04
Unlimited staff accounts
Shopify Plus removes all per-seat licensing restrictions. Your entire team — merchandisers, customer service, logistics, finance — can access the admin with role-specific permissions at no extra cost.
05
Multi-store under one Organisation
Manage up to 10 expansion stores from a single Shopify Plus Organisation — separate storefronts for each market, currency, or brand, all with shared reporting and one billing relationship with Shopify.
06
Priority Shopify support
Shopify Plus merchants get 24/7 priority support with a dedicated Merchant Success Manager — not a shared support queue. Critical issues get escalated directly to Shopify engineering.
What we build
12 Shopify Plus services.
From a custom Liquid theme to a headless multi-store Organisation — all built in-house in London with a full launch handover.
01
Custom Shopify Plus Theme (Liquid)
Pixel-perfect custom Liquid themes built for conversion — responsive, sub-2s load times, structured data, and Section Everywhere architecture so your merchandising team can build new pages without a developer.
02
Shopify Plus B2B Wholesale Setup
Full Shopify Plus B2B configuration: company accounts, customer-specific price lists, net payment terms, purchase order workflows, and a gated wholesale storefront — all native to Shopify Plus, no third-party app required.
03
Shopify Plus Checkout Extensibility
Custom checkout UI components using Checkout Extensions — branded order summaries, loyalty point redemption, custom upsells, address validation, and delivery date pickers — all built to survive Shopify Plus upgrades.
04
Shopify Plus Flows & Automation
Complex Shopify Flows built for enterprise DTC — customer tagging, fraud screening, inventory alerts, multi-step Klaviyo triggers, order routing, and custom B2B approval workflows without custom code.
05
Shopify Plus Multi-Store / Expansion Stores
Multi-store architecture under a single Shopify Plus Organisation — separate storefronts per market, brand, or currency, with shared customer data, consolidated reporting, and one billing relationship.
06
Shopify Plus Subscription Commerce (ReCharge)
End-to-end subscription commerce built on ReCharge — subscription product setup, customer portal customisation, dunning management, and upgrade/downgrade flows — fully integrated with your Shopify Plus store.
07
Shopify Plus Migration (Magento / WooCommerce)
Full data migration from Magento, Adobe Commerce, or large WooCommerce stores to Shopify Plus — products, variants, customers, order history, reviews, metafields, and 301 redirects for every URL.
08
Shopify Plus App Integrations (Klaviyo, Yotpo, Gorgias)
Deep integration of your Shopify Plus stack — Klaviyo flows, Yotpo reviews and loyalty, Gorgias helpdesk, Attentive SMS, ReCharge subscriptions, and any third-party fulfilment or ERP system via API.
09
Shopify Plus Headless (Next.js Hydrogen)
Headless Shopify Plus frontend built on Next.js — Shopify Storefront API, sub-second page loads on Vercel Edge CDN, complete design freedom, and Shopify Plus checkout as the reliable backbone.
10
Shopify Plus International & Multi-Currency
Shopify Markets configuration for international expansion — localised pricing, translated content, duty and tax handling, currency conversion, and market-specific domains or subfolders with hreflang tags.
11
Shopify Plus Analytics & Reporting
Custom Shopify Plus reporting dashboards, Shopify Analytics configuration, GA4 enhanced ecommerce tracking, Klaviyo attribution reporting, and integration with Looker Studio or existing BI tools.
12
Shopify Plus Maintenance & Retainers
Post-launch retainers covering theme updates, new feature builds, app integrations, Shopify Plus platform upgrades, Flow maintenance, and performance monitoring. Monthly plans from £600/month.

Migrating from Magento? See our Shopify migration service →
Platform migrations
Moving to Shopify Plus from another platform?
We migrate Magento, WooCommerce, BigCommerce, and standard Shopify stores to Shopify Plus — all products, customers, order history, and SEO equity preserved. 301 redirects handled as standard.
Magento → Shopify Plus
The most complex migration we handle. We map Magento attribute sets to Shopify Plus metafields, migrate ERP integrations, rebuild B2B pricing logic natively, and configure 301 redirects for every Magento URL. Full data migration — products, customers, orders, reviews.
WooCommerce (large store) → Shopify Plus
Large WooCommerce stores often carry plugin debt and performance issues. We migrate all products, customers, order history, and reviews to Shopify Plus — and take the opportunity to simplify your tech stack and improve checkout conversion rates.
BigCommerce Enterprise → Shopify Plus
Similar SaaS architecture makes this one of the cleaner migration types. We map BigCommerce product data to Shopify Plus metafields, migrate customer accounts and order history, and configure 301 redirects. Usually the fastest enterprise migration we run.
Shopify (standard) → Shopify Plus upgrade
Moving from standard Shopify to Shopify Plus is not just a plan upgrade — it is a rebuild opportunity. We configure B2B, unlock Checkout Extensibility, set up Shopify Flows, and restructure your multi-store architecture to take full advantage of the Plus tier.

Platform comparison
Shopify Plus vs the alternatives.
We build on multiple platforms. Here is an honest four-way comparison — Shopify standard, Magento, BigCommerce Enterprise, SFCC — so you can make the right call.
| vs Platform | Shopify Plus wins on | They win on | Choose Shopify Plus when |
|---|---|---|---|
| Shopify standard | Checkout Extensibility, B2B native, Shopify Flows, unlimited staff, multi-store Organisation, Shopify Plus support SLA | Lower monthly cost (Shopify Plus is $2,300/month vs standard from $39/month), simpler for small catalogues | You need B2B wholesale, complex checkout customisation, or multiple storefronts under one roof |
| Magento / Adobe Commerce | Faster time to market, lower total cost of ownership, zero server maintenance, native B2B, 8,000+ app ecosystem, better mobile checkout conversion | Open source flexibility, complex custom business logic, on-premise hosting control for regulated industries | Your Magento maintenance costs are eating your margin and you want a managed platform that scales |
| BigCommerce Enterprise | Larger app ecosystem, better headless story with Hydrogen, stronger brand recognition for investors and partners, Checkout Extensibility | No revenue-based transaction fees, slightly lower enterprise pricing, native multi-storefront on all plans | App ecosystem breadth, headless capabilities, and partner network depth matter for your roadmap |
| SFCC (Salesforce Commerce Cloud) | Lower total cost of ownership, faster deployment, modern developer experience, Hydrogen for headless, no per-GMV licensing | Salesforce ecosystem integration (Marketing Cloud, Service Cloud), legacy enterprise feature depth, compliance certifications | You want enterprise features at a fraction of SFCC cost without a 12-month implementation project |

FAQ
Shopify Plus questions, answered directly.
What is Shopify Plus?
Shopify Plus is the enterprise tier of Shopify, designed for high-volume brands and businesses with complex requirements. It unlocks Checkout Extensibility (custom checkout UI), native B2B wholesale features, Shopify Flows for no-code automation, unlimited staff accounts, multi-store Organisation management for up to 10 stores, Shopify Markets for international expansion, and a dedicated Merchant Success Manager. Shopify Plus starts from approximately $2,300/month on a revenue-based model.
How much does Shopify Plus development cost in London?
A Shopify Plus project from WebAnts starts from £8,000 for a custom Liquid theme with basic B2B setup (4–5 weeks). A full Shopify Plus build with B2B, Checkout Extensibility, and Flows typically costs £14,000–£25,000 (5–8 weeks). Multi-store or headless builds range from £25,000–£40,000. Enterprise multi-market projects start from £40,000. All prices are flat fees — written quote after a free 30-minute discovery call, no deposit required.
What is the difference between Shopify and Shopify Plus?
Shopify Plus unlocks features unavailable on standard Shopify: Checkout Extensibility (custom checkout UI components), native B2B catalog and price lists, Shopify Flows (complex no-code automation), unlimited staff accounts (standard Shopify caps at 15), multi-store Organisation (up to 10 stores), Shopify Markets for international, launchpad for sale events, and 24/7 priority support with a dedicated Merchant Success Manager. Plus also removes Shopify's standard transaction fees on third-party payments.
What is Shopify Plus Checkout extensibility?
Shopify Plus Checkout Extensibility replaced the legacy checkout.liquid file and allows merchants to customise the checkout UI using Shopify's UI Extensions framework. You can add custom blocks (upsell offers, loyalty redemption, custom fields), brand the order summary, add delivery date pickers, and create post-purchase pages — all without touching Shopify's core checkout code. Extensions survive Shopify platform upgrades, unlike checkout.liquid modifications.
What is Shopify Plus B2B?
Shopify Plus B2B is a native set of wholesale features built into Shopify Plus — no third-party app required. It includes company account management, customer-specific price lists, payment terms (Net 30/60/90), purchase order workflows, quantity rules and order minimums, and a gated wholesale storefront. B2B orders flow through the same Shopify admin as DTC orders, giving a unified view of all revenue.
When should a business upgrade to Shopify Plus?
Most businesses upgrade to Shopify Plus when they hit one or more of these thresholds: annual GMV above £1M (where Plus pays for itself via reduced transaction fees and Shopify support), need for B2B wholesale alongside DTC, need for custom checkout UI (Checkout Extensibility), requirement for multiple storefronts (expansion stores), or need for complex automation (Shopify Flows) that cannot be handled with standard apps. WebAnts can advise on the right moment based on your current Shopify plan and growth trajectory.
What are Shopify Flows?
Shopify Flows is a no-code visual automation builder exclusive to Shopify Plus. It allows you to create multi-step workflows triggered by store events — for example: tag a customer as VIP when their lifetime spend exceeds £500 and automatically add them to a Klaviyo segment, send an internal Slack notification, and apply a discount. Flows can automate customer management, inventory alerts, order tagging, fraud screening, B2B approval workflows, and cross-store logic for Plus Organisations.
Shopify Plus vs Magento — which should I choose?
Shopify Plus is the right choice for most brands migrating from Magento: lower total cost of ownership (no server costs, no developer-dependent maintenance), faster time to market, a modern developer experience, and a 8,000+ app ecosystem. Magento still wins for businesses needing extreme custom backend logic, complex ERP integrations with legacy systems, or on-premise hosting for regulatory reasons. If your Magento maintenance cost exceeds £2,000/month, Shopify Plus almost always delivers better ROI. WebAnts handles Magento to Shopify Plus migrations.
Shopify Plus vs BigCommerce Enterprise — what's the difference?
Both are enterprise SaaS ecommerce platforms with similar feature sets. Shopify Plus wins on app ecosystem breadth (8,000+ vs BigCommerce's 1,000+), headless capabilities (Hydrogen, Oxygen), developer community size, and brand investor recognition. BigCommerce Enterprise has no revenue-based transaction fees on its native gateway and slightly lower enterprise pricing. For most London brands, Shopify Plus is the stronger choice due to the ecosystem and partner network depth.
Can Shopify Plus handle B2B wholesale pricing?
Yes. Shopify Plus includes native B2B functionality — company profiles, customer-specific price lists, payment terms (Net 30/60/90), purchase order workflows, and a gated wholesale storefront. You can run DTC and B2B from the same Shopify Plus store with different customer experiences, pricing, and payment methods. WebAnts configures full B2B setups including custom Checkout Extensions for B2B-specific checkout flows.
What is a Shopify Plus Organisation?
A Shopify Plus Organisation is the top-level container in Shopify Plus that allows you to manage multiple stores (up to 10 expansion stores) from a single admin. Stores within an Organisation share staff accounts, can run Shopify Flow automations across stores, and consolidate reporting. This is used by brands running separate storefronts per market (UK, US, EU), per brand, or per channel (DTC vs wholesale).
Can Shopify Plus run multiple stores?
Yes. Shopify Plus allows up to 10 expansion stores within a single Organisation. Each store is a fully independent Shopify store with its own domain, currency, language, product catalogue, and checkout — but all managed under one billing relationship and with shared staff accounts. WebAnts designs multi-store architectures for brands operating across multiple markets or running separate DTC and wholesale channels.
What is Shopify Plus headless?
Shopify Plus headless means decoupling the storefront frontend from Shopify's backend — using Shopify Storefront API or Hydrogen as the data layer, and building the customer-facing frontend in Next.js or another React framework. This enables sub-second page loads, complete design freedom beyond Liquid theme constraints, and the ability to serve product data across web, mobile app, and other channels from a single Shopify Plus backend.
How does Shopify Plus multi-currency work?
Shopify Plus uses Shopify Markets for international expansion — each market gets its own pricing (manual or automatically converted), currency, language, and domain or subfolder. Shopify Payments processes multi-currency transactions natively. You can set market-specific prices (useful for UK/EU/US pricing strategies), restrict products by market, and configure duty and import tax collection for international orders.
What apps do you integrate with Shopify Plus?
WebAnts integrates the full Shopify Plus app stack: Klaviyo (email and SMS automation), Yotpo (reviews and loyalty), Gorgias (helpdesk), Attentive (SMS), ReCharge (subscriptions), Okendo (reviews), Skio (subscriptions), Loop Returns, Postscript, Privy, and any ERP or 3PL system via the Shopify API. We also build custom Shopify apps and API integrations where off-the-shelf solutions fall short.
Can you migrate from Magento to Shopify Plus?
Yes. WebAnts handles full Magento to Shopify Plus migrations — product catalogue (including complex attribute sets mapped to metafields), customer accounts, order history, reviews, and 301 redirects for every Magento URL. We also rebuild B2B pricing logic natively in Shopify Plus and reconnect ERP and fulfilment integrations. Migration projects start from £25,000 depending on catalogue size and complexity.
What is the Shopify Plus subscription plan cost?
Shopify Plus pricing starts at $2,300 USD per month on a fixed monthly plan, or 0.25% of monthly platform GMV (whichever is higher) on a revenue-based model. This covers up to 10 expansion stores, unlimited staff, priority support, and access to all Plus-exclusive features. Shopify Payments transaction fees are also reduced or eliminated on Shopify Plus depending on your plan. WebAnts can help you model whether Plus ROI makes sense for your current GMV.
Do you offer Shopify Plus maintenance retainers?
Yes. After launch you can take full ownership of your Shopify Plus store, or continue with a monthly retainer covering theme updates, new feature builds, Flow maintenance, app integrations, Checkout Extension updates following Shopify upgrades, and performance monitoring. Shopify Plus retainers with WebAnts start from £600/month.
What is the Shopify Plus partner program?
The Shopify Plus Partner Program is a certification for agencies that have demonstrated expertise in building enterprise Shopify Plus solutions. Plus Partners have access to Shopify Plus development stores, dedicated Plus partner support, early access to new Plus features, and co-marketing opportunities. WebAnts is an experienced Shopify Plus development agency — we can share references from Shopify Plus merchants on request.
Can Shopify Plus handle subscription commerce?
Yes. Shopify Plus supports subscription commerce natively through the Shopify Subscriptions API, which third-party apps like ReCharge, Skio, and Ordergroove use to power their subscription engines. We recommend ReCharge for most Shopify Plus subscription builds — it supports subscribe-and-save, prepaid subscriptions, custom customer portal styling, dunning management, and Klaviyo integration. Subscription products run through Shopify Plus checkout natively.
