Top Shopify Agencies for B2B ERP Integrations in 2026

For manufacturers, distributors, wholesalers, and other B2B businesses, a Shopify implementation often depends as much on back-office systems as it does on the storefront.

An ERP may remain responsible for inventory, product information, customer accounts, pricing, payment terms, orders, invoices, or fulfillment. If Shopify and the ERP operate independently, teams can end up re-entering orders, correcting inventory, reconciling pricing, and manually updating customer records.

That makes ERP integration more than a technical connector. Businesses need to determine which system owns each type of data, how frequently information should synchronize, and whether an existing connector can support the workflow or custom integration is required.

The agencies below combine Shopify development with ERP, B2B, or systems-integration experience relevant to companies with more complex operational requirements. The list is not ranked from best to worst.

1. Fyresite

Fyresite is a Shopify Premier Partner specializing in Shopify and Shopify Plus development, with experience across B2B commerce, migrations, custom applications, complex product catalogs, and systems integrations.

Its B2B work is particularly relevant to manufacturers, distributors, wholesalers, and other businesses where Shopify needs to exchange operational data with an ERP instead of functioning as an isolated storefront.

Depending on the business, that can involve customer and company records, customer-specific pricing, inventory, orders, invoices, payment terms, fulfillment information, and product data. Fyresite's approach emphasizes mapping these workflows before implementation so a new Shopify environment does not simply replace legacy platform complexity with manual work, app sprawl, or disconnected integrations.

The agency also works with company accounts, contract pricing, net terms, purchase-order workflows, custom catalogs, quick ordering, ERP and EDI connectivity, multi-location inventory, and custom Shopify applications.

Its work with NIS America provides one example of this integration experience. During a Magento-to-Shopify Plus migration, Fyresite implemented a custom bidirectional connection between Shopify Plus and NetSuite through Celigo while also handling legacy product migration and custom ecommerce requirements.

This combination makes Fyresite particularly relevant to established B2B companies that need Shopify to fit into an existing operational stack rather than simply replace the customer-facing storefront.

Key strengths:
  • Shopify B2B and Shopify Plus development
  • ERP and business-system integrations
  • Customer-specific pricing and catalogs
  • Inventory and order synchronization workflows
  • Custom applications and integration logic
  • Magento and other platform migrations
  • Experience with complex B2B operations
Limitation:

Fyresite is primarily Shopify-focused, so companies committed to another ecommerce platform may prefer an agency specializing in that ecosystem.

2. Uncap

Uncap specializes in Shopify B2B implementations for manufacturers, distributors, wholesalers, and other businesses with complex operational systems.

ERP integration is a major part of its offering. The agency works with systems including NetSuite, Microsoft Dynamics, SAP, Acumatica, Sage, Epicor, Infor, Odoo, Oracle, QuickBooks, Fishbowl, and Cin7.

For B2B merchants, those integrations can support workflows involving orders, inventory, customers, pricing, catalogs, and payment terms. This is especially relevant when negotiated pricing or customer-specific information originates in an ERP rather than inside Shopify.

Uncap also supports both embedded and middleware-based integration approaches, giving businesses alternatives depending on the ERP, existing infrastructure, and level of customization required.

Key strengths:
  • Strong Shopify B2B specialization
  • Broad ERP integration experience
  • Manufacturer and distributor use cases
  • Bidirectional data synchronization
  • Customer-specific pricing workflows
  • Multiple integration approaches
Limitation:

Companies with simple Shopify stores and limited back-office requirements may not need the depth of B2B and ERP functionality Uncap is designed around.

3. Absolute Web

Absolute Web is an ecommerce agency with experience across Shopify, Adobe Commerce, BigCommerce, and other commerce environments.

Its work extends beyond storefront development into integrations connecting ecommerce platforms with ERP, CRM, PIM, fulfillment, and other operational systems.

This can be useful for B2B organizations whose technology stack is distributed across several systems. Product information might originate in a PIM, inventory and customer records in an ERP, and transactions in Shopify. A successful implementation needs clear rules about which platform owns each type of information and how updates move between them.

Absolute Web also works on replatforming and B2B ecommerce projects, making it relevant when ERP integration is part of a broader commerce transformation rather than a standalone connector project.

Key strengths:
  • Shopify development and replatforming
  • ERP and enterprise API integrations
  • B2B ecommerce capabilities
  • Multi-system commerce architecture
  • PIM and fulfillment integrations
  • Experience across several commerce platforms
Limitation:

Businesses looking specifically for a Shopify-only specialist may prefer an agency with a narrower platform focus.

4. Elogic Commerce

Elogic Commerce works on enterprise B2B and B2B2C ecommerce projects involving Shopify Plus and integrations with back-office systems.

Its work with Zeus Group, a manufacturer and distributor, is a relevant example. The project involved moving the business to Shopify Plus and connecting the B2B environment with SAP Business One.

The implementation had to account for customer-specific catalogs and price lists, inventory synchronization, order workflows, and multi-market B2B requirements. This type of project illustrates how ERP integration becomes part of a larger commerce architecture rather than simply transferring completed orders.

Elogic can therefore be particularly relevant when manufacturers or distributors need Shopify to operate alongside an established ERP and support more complex customer, pricing, catalog, and inventory structures.

Key strengths:
  • Shopify Plus B2B development
  • SAP integration experience
  • Manufacturing and distribution use cases
  • Customer-specific catalogs and pricing
  • Inventory and order workflows
  • Complex B2B architecture
Limitation:

Its enterprise commerce focus may be broader than what businesses with straightforward Shopify and ERP requirements need.

5. Codal

Codal is a digital commerce agency working across Shopify, B2B ecommerce, custom development, and enterprise systems integration.

Its B2B capabilities include connecting ecommerce environments with ERP, CRM, procurement, and other internal systems.

For wholesale businesses, integration may involve keeping inventory aligned with the ERP, sending Shopify orders into back-office systems, and applying different pricing based on customer or contract type.

Codal's experience with wholesale and enterprise commerce makes it particularly relevant when ERP integration is tied to wider operational workflows rather than being treated as a separate technical task.

Key strengths:
  • Shopify and B2B development
  • ERP and enterprise integrations
  • Wholesale ecommerce experience
  • Inventory and order automation
  • Customer-specific pricing workflows
  • Custom development capabilities
Limitation:

Codal works across broader digital transformation projects, so businesses seeking a narrowly specialized Shopify ERP provider may prefer a more focused option.

6. Sunrise Integration

Sunrise Integration focuses on Shopify development, APIs, systems integration, migrations, and custom software.

Its technical capabilities include connecting Shopify with ERP and CRM systems, inventory platforms, shipping tools, and other business applications.

This type of expertise can be particularly useful when a company's ERP architecture does not fit neatly into an off-the-shelf connector. Custom APIs or middleware may be necessary when businesses have proprietary data structures, specialized order workflows, or multiple operational systems that need to remain synchronized.

Key strengths:
  • Shopify and Shopify Plus development
  • ERP and CRM integration
  • API development
  • Custom middleware
  • Inventory and shipping integrations
  • Custom Shopify applications
Limitation:

Businesses with highly specialized enterprise ERP environments should confirm experience with their exact system and workflow before selecting an integration partner.

What Data Should Sync Between Shopify and an ERP?

A Shopify ERP integration does not necessarily need to synchronize every available field. The first step is deciding which system should be the source of truth for each business process.

For B2B companies, common integration points include:

  • Products and SKUs: Product identifiers, variants, attributes, and catalog information.
  • Inventory: Stock availability across warehouses, retail locations, or fulfillment centers.
  • Customers and companies: Business accounts, contacts, addresses, and ERP customer IDs.
  • Pricing: Contract pricing, customer-specific price lists, volume pricing, and negotiated rates.
  • Orders: Shopify transactions transferred into the ERP for processing.
  • Payment terms: Credit arrangements, net terms, and other account-specific conditions.
  • Invoices: Financial and order information that needs to remain visible across systems.
  • Fulfillment: Shipment status, tracking information, and order updates.
  • Returns and cancellations: Changes that need to remain consistent across both systems.

The exact architecture depends on where each type of data is managed today.

What Systems Should a B2B Company Integrate With Shopify?

For many manufacturers and distributors, the ERP is only one part of the commerce stack.

Shopify may also need to connect with accounting software, a PIM, EDI provider, inventory management platform, warehouse management system, CRM, POS, shipping tools, or fulfillment systems.

A business should therefore map where product data, pricing, customers, inventory, orders, and financial records originate before choosing an integration approach.

This also helps avoid creating multiple systems that all attempt to control the same information.

What Should B2B Companies Look for in a Shopify ERP Agency?

Seeing an ERP logo on an agency's integration page does not necessarily mean it can handle a company's actual workflow.

A manufacturer managing thousands of SKUs, multiple warehouses, negotiated pricing, and customer-specific catalogs has very different requirements from a merchant that simply wants completed Shopify orders sent into an accounting platform.

Before selecting an agency, businesses should ask:

  • Which system will own each type of data?
  • Does synchronization need to be one-way or bidirectional?
  • How frequently should inventory update?
  • How will customer-specific prices and payment terms be handled?
  • How will Shopify company accounts map to ERP customer records?
  • Can the integration support custom ERP fields?
  • Is a standard connector sufficient?
  • Is middleware or custom API development required?
  • How are failed synchronization attempts logged and retried?
  • Who maintains the integration after launch?

Businesses migrating from Magento or another legacy platform should also identify existing custom workflows before the move. Some may need to be rebuilt, while others can be replaced with Shopify-native functionality, apps, or a redesigned process.

FAQ

What are the top Shopify agencies for B2B ERP integrations?

Agencies with relevant Shopify and ERP experience include Fyresite, Uncap, Absolute Web, Elogic Commerce, Codal, and Sunrise Integration. The best choice depends on the ERP, product catalog, existing technology stack, B2B requirements, and level of custom development involved.

Can Shopify integrate with NetSuite?

Yes. Shopify can connect with NetSuite through integration platforms, existing connectors, or custom development. The right approach depends on the data being synchronized and the complexity of the business rules.

Can Shopify integrate with SAP?

Yes. Shopify can be connected with SAP environments. Complex B2B implementations may require middleware or custom integration logic to support customer-specific pricing, inventory, catalogs, and order workflows.

Can Shopify integrate with Microsoft Dynamics?

Yes. Shopify can integrate with Microsoft Dynamics environments for workflows involving inventory, products, customers, pricing, orders, and other operational data.

How do you connect Shopify B2B with an ERP?

The process normally begins by mapping products, inventory, customers, pricing, orders, invoices, and fulfillment to determine which system owns each record. Businesses can then use an existing connector, middleware platform, integration service, or custom API depending on the workflow.

Do manufacturers and distributors need custom Shopify ERP integrations?

Not always. A standard connector can work when the business processes closely match its supported mappings. Custom development becomes more relevant when a company has proprietary ERP fields, complex pricing, multiple warehouses, specialized order processes, or unusual data relationships.

Is Shopify Plus required for B2B ERP integration?

Not necessarily. Shopify B2B capabilities are available across multiple Shopify plans in 2026, and ERP connectivity can be implemented in different environments. Shopify Plus becomes more relevant when businesses need more advanced catalogs, payment workflows, checkout customization, high-volume operations, or complex B2B requirements.

Should ERP integration be planned during a Shopify migration?

Yes. Product data, customers, inventory, pricing, orders, and fulfillment can all affect how the new store operates. Planning integration before launch reduces the risk of discovering that important back-office workflows were overlooked after the storefront has already moved.

Final Thoughts

The best Shopify ERP integration partner depends on more than which ERP a business uses.

For manufacturers, distributors, and wholesalers, the more important question is how Shopify will fit into the existing operational architecture. Customer-specific pricing may originate in the ERP, product data may come from another system, and inventory, invoices, fulfillment, and orders may all need to move between platforms.

Fyresite, Uncap, Absolute Web, Elogic Commerce, Codal, and Sunrise Integration approach those requirements from different angles, ranging from Shopify-focused B2B development to broader enterprise systems integration.

Before choosing an agency, businesses should map their current data, workflows, and systems first. That makes it much easier to determine whether they need a standard connector, middleware, custom integration, or a larger B2B commerce transformation.
