For high-volume WooCommerce stores — those doing $1M+ annually, running complex B2B operations, or needing custom checkout logic — Shopify Plus offers capabilities unavailable on standard Shopify plans. This guide covers when to migrate directly to Plus rather than standard Shopify, and what Plus-specific features to configure during migration.

When to choose Shopify Plus

Revenue threshold: Shopify Plus starts at approximately $2,300/month (or 0.25% of monthly revenue, whichever is greater). If you're spending $500+/month on WooCommerce plugins, hosting, and developer maintenance, the economics often favor Plus sooner than expected.
Complex B2B pricing: Multiple price lists per customer account, net payment terms, purchase order workflow
Custom checkout logic: Checkout Extensibility allows adding steps, custom UI, and validation not available on standard plans
High order volume: Flash sales, large catalog, Black Friday scale. Plus has no transaction fees with Shopify Payments.
Multi-store management: Organization Admin manages multiple storefronts from one dashboard
Dedicated support: Launch engineer, dedicated success manager

Shopify Plus vs standard Shopify: key differences for WooCommerce migrants

Feature	Shopify (standard)	Shopify Plus
Checkout customization	Limited (theme CSS only)	Checkout Extensibility — full UI blocks, custom validation
B2B native features	None (apps required)	B2B: price lists, company accounts, net terms, draft orders
Automation	Shopify Flow (basic)	Shopify Flow + Launchpad + advanced triggers
Transaction fees	0.5–2% without Shopify Payments	0% transaction fees
API rate limits	Standard	4× higher rate limits
Exclusive apps	N/A	Scripts (legacy), Checkout Extensibility, Launchpad
Multi-store	Separate accounts	Organization Admin: centralized management
Staff accounts	Limited	Unlimited
Markets	Standard	Plus: expansion stores for complex localization

Checkout Extensibility (replaces Shopify Scripts)

WooCommerce enterprises often have heavily customized checkout — custom fields, upsell steps, loyalty integrations, B2B validation. On Shopify Plus, Checkout Extensibility (replacing the deprecated Scripts API) handles this:

What Checkout Extensibility provides

Checkout UI extensions: Add custom UI blocks before/after payment, shipping, or order summary sections
Custom validation: Prevent checkout if order doesn't meet criteria (e.g., minimum order value, restricted products for certain regions)
Payment customization: Hide, rename, or reorder payment methods
Shipping customization: Hide, rename, or reorder shipping methods based on order criteria
Discount validation: Custom discount logic beyond standard Shopify discount codes

WooCommerce checkout customizations → Checkout Extensibility mapping

Custom checkout fields (WC Checkout Field Editor) → Checkout UI extension with metafield input blocks
Payment gateway restrictions → Payment customization function
Shipping method filtering by weight/zone → Shipping customization function
Minimum order validation → Custom validation function
Age verification step → Checkout UI extension with age confirmation block
B2B purchase order number field → Checkout UI extension storing to order metafield

Shopify B2B (native — Plus only)

For WooCommerce B2B stores using Wholesale Suite, B2B King, or custom role-based pricing, Shopify Plus B2B is the professional replacement:

B2B feature set

Company accounts: A Company object has multiple Locations (delivery addresses) and Contacts (buyers)
Price lists: Assign custom price lists to companies — percentage off, fixed prices, or per-product overrides
Net payment terms: Net 30, Net 60, Net 90 — invoices generated, payment via bank transfer
Draft orders: Sales reps create orders on behalf of B2B customers
B2B-only storefront: Restrict entire store to logged-in company contacts only
Purchase order numbers: Capture PO number on orders
Quantity rules: Minimum order quantities, case pack increments per product per price list

Migrating WooCommerce B2B customers to Shopify B2B

Export customer list from WooCommerce including company name, billing address, assigned role
Map WooCommerce customer roles to Shopify B2B companies
Create Company records in Shopify Admin (or via API: companyCreate mutation)
Create Contacts (customer accounts) linked to each Company
Assign price lists to each Company
Migrate order history linked to the Company

Launchpad (Plus-only automation)

Launchpad schedules storefront events — product launches, flash sales, collection reveals:

Schedule price changes for sale events (auto-revert after event ends)
Schedule product publishing/unpublishing (new collection launch at midnight)
Enable/disable discount codes on a schedule
Lock storefront to a countdown page before a launch
WooCommerce equivalent: custom cron jobs + WP_Cron + manual price changes. Launchpad replaces all of this.

Multi-store architecture with Organization Admin

WooCommerce multisite or multi-domain setups (different stores per country, brand, or B2B/B2C split) map to Shopify Plus Organization Admin:

Each store (expansion store) is a separate Shopify store with its own domain, theme, and catalog
Organization Admin: single login to see all stores, aggregate reports, user management across stores
Shared catalog options: duplicate products via Shopify API or use a PIM to sync catalog across stores
Markets (non-Plus): for simple internationalization (currency, language, pricing per country) without separate stores
Expansion stores: for true storefront separation — different designs, catalogs, or fulfilment regions

Shopify Flow automation (enhanced on Plus)

Shopify Flow replaces custom WooCommerce webhook handlers, automation plugins, and cron-based automations:

Auto-tag high-value customers on first purchase above threshold
Trigger Slack notification for large orders
Auto-archive orders with zero-value refunds after 90 days
Pause fulfillment if fraud score exceeds threshold (Plus: fraud analysis triggers)
Auto-send restock email via Klaviyo when inventory drops below par level
Auto-apply B2B discount code when company customer logs in

Plus migration checklist

Engage Shopify Plus launch engineer at start of migration — they provide migration support
Inventory all WooCommerce checkout customizations (custom fields, payment restrictions, validation)
Rebuild checkout logic using Checkout Extensibility (not Scripts — Scripts is deprecated)
Export B2B customer list: company names, contacts, price tiers, payment terms
Create Company and Contact records in Shopify B2B before launch
Configure B2B price lists — replicate all wholesale pricing tiers
Set up Launchpad for any scheduled launches or flash sales during migration window
Configure Organization Admin if running multi-store setup
Set up Shopify Flow automations: replace WooCommerce webhook-based triggers
Test B2B checkout end-to-end with net terms payment
Verify API rate limits are sufficient for catalog size (Plus: 4× standard limits)
Negotiate Plus pricing: revenue-based fee is negotiable at launch; annual contract vs month-to-month

Shopify Plus's launch engineer program is one of the most underutilized migration resources available. Large WooCommerce migrations to Plus are assigned a dedicated engineer who has seen hundreds of migrations — leverage their checklist, their knowledge of common migration failures, and their escalation path to Shopify engineering teams. Plan to spend the first 2 weeks of Plus engagement just on discovery with the launch engineer before writing a single line of code.
