10 B2B Ecommerce Businesses That Migrated to Shopify Plus and What Changed
For most of the 2010s, Shopify was understood as a consumer commerce platform. B2B wholesale operations built on Magento, WooCommerce, Pinnacle Cart, or older custom systems had few reasons to consider it. The feature set was not there. The B2B-specific infrastructure, company accounts, contract pricing, net terms, ERP integration, simply did not exist.
That changed. Over the past four years, Shopify has invested heavily in B2B-specific functionality, and the platform now supports the full range of requirements that manufacturers, distributors, and wholesale operators carry into an ecommerce build. The result has been a sustained migration wave: B2B businesses leaving legacy platforms for Shopify Plus, in most cases for the same reasons, administrative complexity, expensive maintenance, poor buyer experience, and integration failure.
Uncap has managed this migration for dozens of B2B operators across industries. The ten case studies below are real implementations, covering migrations from nine different legacy platforms and a range of industries from railway maintenance to marine products. Each one illustrates a different version of the same decision: the platform the business was on had reached the limit of what it could support, and Shopify Plus was the platform that could carry them forward.
B2B operators migrate to Shopify Plus for a narrow set of repeatable reasons. Understanding them provides context for the case studies below.
Platform maintenance costs had grown unsustainable. Legacy platforms like Magento and Drupal require dedicated development resources to maintain, update, and patch. As platforms age and teams turn over, the technical debt compounds. Operators find themselves spending more on keeping the existing site functional than on improving it.
ERP integration had broken down or never worked properly. The ERP is the operational core of most B2B businesses: inventory levels, pricing, customer records, and order history live there first. When the commerce platform cannot sync reliably with the ERP, the result is manual re-entry, inventory discrepancies, and orders that require intervention at every stage. This is the single most common technical failure Uncap encounters in pre-migration audits.
The buyer experience had fallen behind expectations. B2B buyers now navigate consumer ecommerce daily. When they log into a wholesale portal that looks and behaves like it was built in 2011, they notice. Poor search, unclear pricing, slow load times, and checkout friction all drive B2B buyers toward suppliers who have solved these problems.
Shopify Plus B2B features reached feature parity. The launch of Shopify B2B native features, company accounts, custom catalogs, price lists, net terms, draft orders, and quantity rules, removed the last structural argument against Shopify Plus for wholesale. Features that previously required expensive third-party apps or custom development are now native to the platform.
Before the case studies, it helps to understand what scope a B2B migration typically covers.
Product catalog migration is usually the most data-intensive part. Product records, variants, images, custom fields, and metadata need to be accurately mapped from the source platform's data structure into Shopify's. Complex variant structures, configurable products, and products with non-standard specifications require careful mapping work rather than automated import.
Customer account migration covers buyer records, order history, company hierarchy, and assigned pricing. For B2B operators with hundreds of active accounts, maintaining the integrity of that data through the migration is not optional, buyers expect their account history and pricing to be intact on day one.
ERP integration is almost always rebuilt from scratch. The existing connection between the legacy platform and the ERP is typically platform-specific and does not transfer. The new integration needs to be designed around Shopify's API and configured to match the ERP's data model, sync frequency, and field mapping. This is the part of most migrations that takes longest and carries the most risk if not planned carefully.
Storefront and theme development is the visible output, but it is typically the least technically complex part of a well-managed migration. Shopify's theme ecosystem and development tools are mature, and the buyer experience can be built correctly from the start when the data and integration layers are stable underneath it.
Industry: Industrial welding supplies | Migrated from: Custom legacy platform
Welding Store is a 70-year-old business with a broad product catalog covering welding equipment, consumables, and safety gear. After seven decades of operating, the business had accumulated a deeply customized ecommerce infrastructure that was expensive to maintain and difficult to extend. The custom platform had served its purpose, but it had created a ceiling: adding new product categories, improving search, or integrating modern marketing tools all required bespoke development work that slowed the business down.
The migration to Shopify Plus was a full rebuild rather than a lift-and-shift. Uncap developed a new site architecture with custom collection filters that let buyers navigate a large, complex catalog without requiring exhaustive keyword search. Badge systems were implemented to highlight key product attributes, safety ratings, compatibility notes, featured items, at the collection level, so buyers could make informed decisions without opening every product page.
Navigation strategy was redesigned from the ground up to reflect how welding professionals actually shop: by application, by brand, by material compatibility. A reward and payment plan solution was layered on top, giving the business a structured way to drive repeat purchasing and order consolidation from its most valuable accounts. The result was a site that could grow with the business rather than requiring another rebuild cycle within five years.
Industry: Electrical supply | Migrated from: Legacy platform
ULE Group is a distributor of electrical products with an extensive catalog that spans thousands of SKUs across product families with significant technical differentiation. The core problem was discovery: the existing site made it difficult for buyers to find the right product efficiently, which drove support volume and reduced conversion on self-service orders.
Uncap built a B2B storefront focused on catalog navigation and search. Advanced search functionality was implemented to handle both keyword and specification-based queries, critical for an electrical distributor where buyers often know the spec they need but not the exact SKU. Navigation was restructured around product categories that matched how electricians and procurement teams think about sourcing, rather than how the legacy platform had organized the catalog.
Custom checkout functionality was developed to support ULE Group's specific ordering workflows, including account-level permissions and order approval routing for buyers operating within company purchasing policies. The combination of improved discovery and checkout customization addressed both the self-service buyer and the procurement-managed buyer in the same platform.
Industry: Railway and transit maintenance | Migrated from: BigCommerce
Industry-Railway Suppliers provides tools, equipment, and safety gear for railway and transit maintenance operations. It is a specialized B2B market with demanding product specifications, compliance requirements, and buyers who are typically purchasing on behalf of infrastructure operators rather than as individual end users.
The migration from BigCommerce to Shopify Plus addressed several structural limitations of the legacy setup. BigCommerce's B2B tooling had not kept pace with Industry-Railway Suppliers' growing requirements for account-level customization, specialized catalog organization, and integration with operational systems. The catalog structure needed to reflect the technical specificity of railway maintenance products, tools categorized by application, track type, and regulatory compliance rather than generic product taxonomy.
Uncap managed the full migration scope, preserving customer accounts, order history, and product data while rebuilding the storefront around a buyer experience appropriate for technical procurement. The go-live was structured to minimize disruption to active accounts during the transition, with parallel testing to confirm data integrity before cutover.
Industry: Commercial cleaning equipment | Migrated from: Cloud Commerce
Sanitaire has nearly 50 years of history manufacturing high-performance commercial cleaning equipment, carpet extractors, backpack vacuums, and industrial floor care products. The company's ecommerce infrastructure had grown slow and rigid on Cloud Commerce, and the ERP integration had become a persistent operational burden rather than a functional asset.
The migration involved moving all product data and customer records from Cloud Commerce to Shopify Plus, a process that required careful field mapping to preserve the specificity of Sanitaire's product catalog, which includes significant technical attribute data relevant to commercial buyers. The ERP integration was rebuilt natively on Shopify's API, restoring reliable inventory sync and order data flow that the Cloud Commerce integration had not been consistently delivering.
A custom quoting system was built as part of the implementation. Sanitaire's commercial buyers frequently require quotes before committing to larger equipment orders, a workflow the previous platform handled through manual processes outside the ecommerce system. The custom quote tool brought that workflow into Shopify, connecting quote requests to specific buyer accounts and allowing the sales team to manage the full quote-to-order cycle within the platform.
Industry: Cleaning and janitorial supplies | Migrated from: Pinnacle Cart
Microfiber Wholesale is a family-owned business with 75 years of history supplying cleaning and janitorial products to businesses, retailers, and institutional buyers. The previous site, built on Pinnacle Cart, had served the business adequately for years but was showing its age: the design was dated, the performance metrics had degraded, and the platform lacked the flexibility to support the growth the business was pursuing.
The critical constraint on the migration was data integrity. A 75-year-old business accumulates significant customer history, order records, and product catalog depth. All of that data needed to transfer cleanly to Shopify Plus without loss or corruption, even while the platform itself was being fully replaced. Uncap managed the migration with a data-first approach: catalog architecture mapped before development started, customer records validated against source data after import, and order history preserved to maintain account continuity for long-standing buyers.
Post-migration, the design and UX improvements drove measurable traffic improvements. The updated storefront addressed mobile performance, navigation clarity, and product presentation in ways that the Pinnacle Cart implementation could not support, creating a buyer experience more consistent with what Microfiber Wholesale's customers encountered on consumer platforms.
Industry: Commercial and residential lighting | Migrated from: Americommerce
Warehouse-Lighting.com supplies a broad range of lighting solutions, commercial fixtures, residential lighting, and specialty applications, to both business buyers and consumers. The platform had been built on Americommerce, which had served the business at an earlier stage but was limiting its ability to improve product configurability and buyer self-service.
The migration unlocked configuration tooling that Americommerce could not support. Warehouse-Lighting.com sells a significant portion of its catalog as configurable products: fixtures with selectable beam angles, color temperatures, mounting configurations, and wattage options. Buyers on the previous site had to contact the sales team to navigate configuration complexity. On Shopify Plus, Uncap implemented configuration tools directly in the product experience, allowing buyers to specify and purchase customized products without friction.
This change had a direct impact on the volume and type of sales inquiries the team handled. Buyers who previously required rep assistance for configuration could complete those decisions independently, shifting the support team's capacity toward higher-value interactions and larger account management.
Industry: Event supply and crowd management | Migrated from: Legacy platform
Crowd Control Warehouse is a supplier of barricades, stanchions, signage, and event management equipment serving venues, event operators, and municipalities. A wide-ranging product catalog, varying by material, configuration, regulatory specification, and use case, had outgrown the platform's ability to present it clearly.
The migration to Shopify Plus centered on data integrity and catalog organization. Crowd Control Warehouse had accumulated years of first-party customer data, order history, and product records that needed to survive the migration intact. Uncap managed the data transfer manually, converting and importing all vital records, because the source platform's export format required significant transformation before it could be loaded into Shopify.
The new storefront addressed the catalog navigation challenges that had been driving search and support volume. Products were organized around event type and application rather than product category alone, making it easier for buyers managing specific event types to find appropriate equipment without cross-referencing multiple catalog sections.
Industry: Water treatment and environmental products | Migrated from: Drupal
Great Lakes Biosystems manufactures eco-friendly water treatment products for both professional and consumer applications. The existing site on Drupal had become a content and performance liability. Drupal requires substantial technical overhead to maintain, and the site's design and content infrastructure were not equipped to communicate the depth and efficacy of Great Lakes Biosystems' product line to technically sophisticated buyers.
The migration from Drupal to Shopify Plus was accompanied by a comprehensive redesign. The new user interface was built to communicate product credibility to buyers who approach water treatment decisions with significant technical scrutiny, professionals specifying treatment solutions for infrastructure, industrial processes, and environmental applications. Product detail pages were expanded with technical content, application guidance, and certification information relevant to professional buyers.
A blog was implemented as part of the migration to support ongoing content education. For a product category where buyer confidence is driven by understanding mechanisms and efficacy rather than brand familiarity, content that explains how products work and what they treat is a meaningful competitive advantage. The blog provides a channel for that content to reach buyers at the research stage of the purchasing cycle.
Industry: Equestrian equipment and apparel | Migrated from: Magento
English Riding Supply is a supplier of equestrian products, riding gear, apparel, horse care equipment, and accessories, serving riders across skill levels and disciplines. The business had been operating on Magento, which provided flexibility at the cost of significant development overhead and ongoing maintenance complexity.
The migration from Magento addressed both the operational burden and the buyer experience gap. Magento's administrative complexity was creating friction for the team managing the catalog and orders day-to-day. Shopify Plus's admin reduced that overhead immediately, giving the team an interface they could operate without constant developer support.
On the B2B side, Uncap rebuilt English Riding Supply's wholesale buying experience on Shopify Plus, adding company account functionality, buyer-specific pricing, and order workflows appropriate for the equestrian retailer and barn manager accounts that make up a significant portion of the business's wholesale volume. The Magento implementation had not supported a coherent B2B experience, wholesale orders were handled through workarounds rather than native functionality. The Shopify Plus build gave the B2B channel the same quality of experience the retail channel had been pursuing.
Industry: Marine products | Migrated from: WooCommerce
TotalBoat is a manufacturer of marine-grade products, epoxy, paint, varnish, cleaners, and maintenance supplies, for boaters, boat builders, and marine craftspeople. The brand had developed strong recognition in the boating community, and the business wanted to extend that brand equity into a more refined digital experience, particularly for the strategic B2B accounts, boat yards, marine retailers, and boat builders, that represented a significant portion of volume.
The WooCommerce implementation had served TotalBoat at an earlier stage of growth but was limiting the brand's ability to build the private portal experience its strategic accounts required. WooCommerce's flexibility comes with the overhead of plugin management, hosting complexity, and custom development for anything beyond standard functionality. Building and maintaining a credible B2B portal on top of WooCommerce had become expensive relative to the outcomes it was producing.
Uncap built the Shopify Plus implementation around TotalBoat's specific goal: a private portal experience for strategic accounts that reflected the brand's quality positioning, supported account-specific catalog curation and pricing, and gave the B2B team visibility into account activity without relying on manual reporting. The transition from WooCommerce to Shopify Plus resolved the platform overhead and delivered a more coherent and curated B2B buyer experience from day one.
Across ten businesses, nine different source platforms, and a wide range of industries, several patterns appear consistently.
The decision to migrate almost never happens because a single feature is missing. It happens because a combination of factors, maintenance cost, integration failure, buyer experience degradation, and team capacity, accumulates to a point where the cost of staying on the existing platform exceeds the cost of moving.
ERP integration is nearly always the most complex part of the migration and the most important to get right. In every case above where an ERP connection existed on the legacy platform, rebuilding that integration on Shopify's API was a significant portion of the total project scope. Operators who underestimate this part consistently experience the most post-launch friction.
The buyer experience improvement is often the most immediately visible outcome, but the operational improvement, the ERP sync reliability, the reduction in manual order processing, the admin efficiency, is usually the higher-value outcome over the first 12 months post-launch.
What platforms do B2B businesses most commonly migrate from to Shopify Plus?
The most common source platforms in B2B migrations to Shopify Plus are Magento (Adobe Commerce), WooCommerce, BigCommerce, and various custom or industry-specific legacy systems. Older platforms like Pinnacle Cart, Americommerce, Cloud Commerce, and Drupal appear regularly in migrations from businesses that built their ecommerce infrastructure 10 or more years ago and have not re-platformed since. Each source platform presents different migration complexity, primarily around data export format, catalog structure, and ERP integration architecture.
How long does a B2B migration from a legacy platform to Shopify Plus take?
A typical B2B migration to Shopify Plus runs from 8 to 16 weeks depending on catalog complexity, ERP integration requirements, and the state of the source data. Migrations with large catalogs, complex variant structures, or deeply customized ERP connections tend to run toward the longer end of that range. The fastest migrations involve clean product data, no existing ERP integration to rebuild, and a storefront that can be built on a standard theme with moderate customization.
Does all the existing data transfer during a Shopify Plus migration?
Product data, customer account records, and order history all transfer during a well-managed Shopify Plus migration, but the process requires active mapping and validation rather than automated transfer. Product data in particular often requires field mapping work, especially when the source platform uses custom attributes, configurable product structures, or product relationships that do not have direct equivalents in Shopify's data model. Order history transfers cleanly for most standard order records.
Do B2B companies need a Shopify Plus agency to migrate?
For B2B operations with ERP integrations, custom pricing logic, or large catalogs, working with an experienced Shopify Plus partner significantly reduces migration risk. The most common post-migration problems, broken ERP sync, missing product data, and account permission errors, are most likely to occur in migrations managed without prior experience in Shopify's B2B data model and API architecture. Uncap's B2B migration practice covers the full migration scope: data, integrations, storefront, and launch.
What is the cost of migrating a B2B ecommerce site to Shopify Plus?
Migration cost varies significantly based on scope. A straightforward product catalog migration with a standard theme build and no ERP integration can run from $15,000 to $40,000. A full B2B migration with ERP integration, custom pricing architecture, company account configuration, and a custom theme build typically runs from $50,000 to $150,000. Shopify Plus itself starts at $2,500 per month. Total cost of ownership on Shopify Plus is typically lower than on Magento or Drupal within 18 to 24 months due to reduced development overhead and maintenance costs.
The businesses above had one thing in common before they migrated: they had spent years working around the limitations of a platform that was no longer the right fit. The migration did not just replace the platform, it removed a ceiling that had been limiting what the operation could do.
