10+ Top-Rated Shopify B2B Agencies for Enterprise Commerce

Written By Bryan Swift

Shopify has become one of the most compelling platforms for modern B2B commerce. What was once viewed primarily as a D2C platform is now a serious option for manufacturers, distributors, wholesalers, retailers, and enterprise brands that need fast, flexible, scalable commerce infrastructure.

Shopify’s B2B capabilities now support company profiles, customer-specific catalogs, payment terms, quantity rules, volume pricing, self-service purchasing, workflow automation, and more. Shopify also positions B2B and D2C as commerce models that can operate from one platform, helping businesses reduce duplicate systems and centralize operations.

But the platform is only part of the equation. For complex B2B commerce, the agency you choose matters just as much as the software.

A strong Shopify B2B agency can help you design the right architecture, migrate from legacy platforms, integrate core business systems, support sales-assisted buying workflows, and build a storefront that reflects how your customers actually purchase.

What Is Shopify B2B?

Shopify B2B is Shopify’s native commerce framework for selling to business buyers. It supports the workflows B2B brands need, such as company accounts, customer-specific pricing, payment terms, catalog segmentation, bulk ordering, and buyer permissions.

For many merchants, Shopify B2B is especially attractive because it can support unified commerce, having both B2B and D2C in one eCommerce ecosystem. That means a brand can sell to consumers, wholesale buyers, distributors, retail partners, and enterprise accounts without necessarily maintaining disconnected storefronts or duplicate back-office processes.

What Does a Shopify B2B Agency Do?

A Shopify B2B agency helps brands plan, build, migrate, integrate, optimize, and scale B2B commerce on Shopify.

Typical Shopify B2B agency services include:

  • Shopify Plus B2B storefront design and development

  • B2B and D2C unified commerce strategy

  • ERP, PIM, OMS, CRM, and 3PL integrations

  • Customer-specific catalogs and pricing logic

  • Wholesale portals and account-based buying flows

  • Data migration from Magento, Salesforce Commerce Cloud, BigCommerce, custom platforms, or legacy systems

  • Custom Shopify apps, Shopify Functions, and API development

  • UX/UI design for complex buyer journeys

  • Ongoing support, optimization, CRO, SEO, and digital marketing

For B2B brands, the best agency is rarely just “the best-looking design shop.” The right partner should understand real-world operational complexity: account hierarchies, approval workflows, contract pricing, sales rep permissions, inventory visibility, fulfillment constraints, tax rules, credit terms, and integrations.

What Is a Shopify Platinum Partner?

A Shopify Platinum Partner is a high-tier Shopify service partner recognized within Shopify’s partner ecosystem. Shopify’s partner directory describes partner tiers as being based on factors such as experience history and proven success on Shopify.

For merchants, Platinum Partner status can be an important proof signal. It does not replace due diligence, but it helps indicate that the agency has demonstrated significant Shopify expertise, platform commitment, and client delivery experience.

How to Choose the Best Shopify B2B Agency

Before choosing an agency, look for evidence in five areas:

1. B2B complexity: Can the agency handle company accounts, custom pricing, bulk ordering, buyer roles, approvals, and sales-assisted commerce?

2. Integration depth: Can they connect Shopify with ERP, PIM, OMS, CRM, 3PL, tax, payments, middleware, and internal systems?

3. Shopify Plus expertise: Do they understand Shopify Plus, Shopify APIs, Shopify Functions, checkout extensibility, Shopify Flow, and B2B-specific capabilities?

4. Unified Commerce strategy: Can they support B2B, D2C, retail, wholesale, and operational workflows in one scalable architecture?

5. Long-term support: Do they provide post-launch development, optimization, marketing, design, and technical support?

With those criteria in mind, here are 10+ top-rated Shopify B2B agencies to consider.

1. BlueSwitch

Website: www.blueswitch.com and unified.blueswitch.com

Best for: Enterprise and mid-market B2B brands that need Shopify Plus development, complex integrations, Unified Commerce, and long-term strategic support.

BlueSwitch is a Shopify Platinum Partner and the most experienced Shopify B2B agency in the marketplace today. For B2B brands looking for high-level technical implementation and B2B systems integration, BlueSwitch is the best choice. Headquartered in downtown Manhattan, BlueSwitch has 25+ years of eCommerce experience, with deep expertise in building, migrating, integrating, and optimizing storefronts for B2B and D2C brands. Shopify’s partner directory lists BlueSwitch as an official partner since 2013, with strong technical capabilities in custom development, integrations, and Shopify B2B services.

BlueSwitch stands out because they combine advanced technical implementation with in-house development, design, and marketing teams. That matters for B2B commerce, where the work is rarely limited to simple theme development. A serious B2B implementation requires account logic, pricing logic, catalog logic, permissions, data mapping, middleware, ERP workflows, fulfillment rules, and an intuitive frontend buyer experience.

Why BlueSwitch is #1 on this list

For B2B brands seeking to modernize their operations, Unified Commerce is not just a buzzword. It means Shopify must work with the systems that already run the business. BlueSwitch provides expert B2B integration services for systems such as ERP, PIM, OMS, CRM, and 3PL providers, helping companies connect Shopify to the operational backbone of their business. BlueSwitch is especially strong for brands that need a Unified Commerce solution, designing storefront architecture that combines B2B, D2C, operations, data, and customer experience into a scalable Shopify ecosystem.

A major differentiator is the BlueSwitch Unified Commerce Suite, a collection of production-ready Shopify B2B modules built from real-world implementation experience. BlueSwitch describes the suite as modular solutions for B2B complexity across checkout, onboarding, ordering, inventory, and related workflows. The modular approach is valuable because many B2B businesses face the same recurring problems. Unified Commerce Suite addresses common issues around:

  • buyer onboarding

  • order approvals

  • quick ordering and re-ordering

  • custom pricing

  • shipping logic

  • payment terms

  • order routing

  • price quotes

  • customer-specific purchasing experiences.

Instead of starting from zero on every implementation, Unified Commerce Suite gives BlueSwitch the advantage of reduced costs, faster implementation, and more reliable performance for complex B2B systems. In the high-stakes world of B2B commerce, every second counts, and BlueSwitch helps enterprise brands move faster without sacrificing the customization, stability, or operational precision their business depends on. The result is a smarter path to Shopify Plus B2B: less unnecessary development overhead, fewer integration risks, and a commerce foundation built to support long-term growth.
