What Shopify Plus
Unlocks for Your Business

Standard Shopify hits a ceiling. Shopify Plus removes it — giving enterprise brands the tools to customize, automate, and scale without limits.

Plus Only

Custom Checkout Scripting

Standard Shopify locks the checkout. Shopify Plus opens it fully — add upsells, custom fields, gift messages, loyalty redemption, and any checkout logic your brand needs via checkout.liquid and Checkout Extensibility.

Plus Only

B2B & Wholesale Portal

Sell to businesses at different prices without a second store. Shopify Plus B2B lets you set customer-specific pricing, net payment terms, company account management, and quote flows — all built natively.

Plus Only

Shopify Flow Automation

Automate your operations — tag high-value customers, trigger fulfillment workflows, pause products when inventory runs low, send internal alerts, and build custom business logic without touching code.

Up to 9 Stores

Multi-Storefront Management

Run up to 9 storefronts under one Plus contract — different regions, brands, or channels. We set up expansion stores, configure currency and language per store, and unify reporting across all of them.

Enterprise

ERP & 3PL Integrations

Connect Shopify Plus to NetSuite, SAP, or any ERP. We build custom API integrations for inventory sync, order routing, warehouse management, and real-time reporting — no middleware limitations.

Plus Only

Launchpad for Sales Events

Schedule and automate flash sales, product drops, and promotional events. Launchpad handles price changes, theme swaps, and discount activations at a precise time — no manual midnight scramble.

Who Shopify Plus
Is Right For

Plus isn't for every store. Here's who gets the most from it — and what it unlocks at each stage.

$1M–$5M Annual Revenue

You've outgrown standard Shopify's checkout limits and need real automation. Plus gives you the tools to scale without hiring more operations staff.

B2B & DTC Hybrid Brands

Selling to both consumers and wholesale buyers? Plus lets you run both on one store — different pricing, payment terms, and portals, no duplicate work.

International Brands

Multi-currency, multi-language, multi-region — Plus expansion stores let you give each market a native experience while managing everything centrally.

High-Volume Flash Sale Brands

Brands doing product drops or time-limited sales at scale need Launchpad and custom checkout to handle the traffic and complexity without breaking.

Enterprise with Existing Systems

If you have an ERP, 3PL, or custom fulfillment setup, Plus's advanced API access lets us build the exact integrations your operations team needs.

Brands Migrating from Magento

Magento's maintenance cost and complexity make Shopify Plus the clear upgrade path. We handle full platform migrations with zero data loss and full SEO preservation.

Shopify Plus
Common Questions

Shopify Plus is Shopify's enterprise plan designed for stores processing $1M+ in annual revenue. It unlocks custom checkout scripting, B2B wholesale portals, advanced automation via Shopify Flow, multi-storefront management, and dedicated Shopify support. If you're scaling fast, selling B2B, or need checkout customizations that aren't possible on standard Shopify, Plus is the right move.
Shopify Plus development at MerchantUp starts from $3,000. The total depends on scope — a custom checkout build is different from a full multi-storefront setup with ERP integration. We always provide a fixed-price quote before starting, with no surprise invoices.
Yes. Migrating to Shopify Plus from standard Shopify or from platforms like Magento, WooCommerce, or BigCommerce is one of our core services. We handle the full migration — products, collections, customer data, order history, redirects, and SEO preservation — with zero downtime on your live store.
Most Shopify Plus builds take 3–6 weeks depending on complexity. Simple Plus setups (checkout customization + theme) run 2–3 weeks. Multi-storefront builds with ERP integrations are scoped individually. We provide a firm timeline before starting and never miss it.
Yes. Shopify Plus is the only plan that allows full checkout customization. We build upsells at checkout, custom field additions, gift message flows, loyalty point redemption, and any checkout logic your brand needs — using both checkout.liquid (for older Plus stores) and Checkout Extensibility (the current standard).
