B2B Shopify merchants often need several integrations across shipping and checkout, enterprise resource planning (ERP), customer relationship management (CRM), product information management (PIM), tax, electronic data interchange (EDI), customer support, and workflow automation. The right combination depends on the workflow being improved, the systems already in place, and the level of customization required.
This guide compares the nine best Shopify integrations by business function. The products are organized by the problems they solve, not ranked from best to worst. Because these tools serve different purposes, a single overall ranking would not provide a meaningful comparison.

These features support common B2B requirements such as:

- Customer-segment rate adjustments
ShipperHQ can also display delivery dates, which helps buyers plan around project schedules and replenishment cycles.

Sirius ERP Connector by Atwix, for ERP and CRM Synchronization
Sirius addresses the back-office data layer of a B2B Shopify operation. Atwix describes bidirectional synchronization for products, inventory, customer data, pricing, orders, and fulfillment.
Sirius is particularly relevant to manufacturers and distributors with customer-specific pricing, contract pricing, account hierarchies, multiple warehouses, or ERP-controlled inventory. It can pass orders from Shopify into the ERP while returning product, pricing, inventory, and fulfillment data to the storefront.
Atwix manages the full implementation process through a structured six-step engagement covering discovery, configuration, testing, deployment, training, and ongoing optimization. Atwix’s ERP integration services provide dedicated architecture and integration support, enabling B2B organizations to connect Shopify to their ERP and CRM systems without managing the technical complexity internally.
Category: ERP and CRM integration
Price Range: Custom quote
Public Review Signal: Atwix’s Clutch profile shows a 4.9/5 overall rating from seven reviews, including 4.8/5 for quality and 4.9/5 for schedule. This is an agency-services rating rather than an independent Shopify App Store score for Sirius.
Features Included: Bidirectional synchronization, ERP connectors, CRM connectors, account pricing, order routing, GraphQL API, and monitoring
| Summary of Online Reviews |
|---|
| Sirius has limited independent software review data because it is positioned as an enterprise connector. A verified Clutch review from a restaurant equipment distributor described Atwix as “a true partner.” The same review praised accurate estimates, clear documentation, and on-time delivery.

SPS Commerce, for EDI and Retailer Connectivity
SPS Commerce is designed for B2B companies that exchange structured documents with retailers, distributors, suppliers, and trading partners. Its Shopify integration supports order visibility, inventory and shipping information, automated document exchange, and advanced shipping notices.
SPS is useful when the workflow includes purchase orders, retailer requirements, partner onboarding, or compliance documents. Its listed connectivity includes:
- Shopify
- 3PLs
- NetSuite
- QuickBooks
- SAP
- ShipStation
- Selected Microsoft business systems
The specific Microsoft products supported should be confirmed before implementation.
Category: Electronic data interchange and retailer connectivity
Price Range: Free to install; external charges may apply
Public Review Signal: 4.9/5 from 7 Shopify reviews
Features Included: EDI, order exchange, inventory visibility, shipping information, advanced shipping notices, and trading-partner workflows
| Summary of Online Reviews |
|---|
| A verified Shopify review from TruHeight Wholesale said, “SPS Shopify integration has been really smooth. It saves me a ton of time since it pushes all info (product details, shipping address, etc.) from SPS over to Shopify as a draft so I can review it and then push it through as an order. If I had to manually enter all these details into Shopify with every retail order, it would take forever. Grateful for the SPS Shopify integration.” SPS Commerce reviews |
Avalara for Shopify, for Tax Compliance
Avalara supports merchants that need tax automation across multiple jurisdictions, entities, products, and sales channels. Shopify’s Avalara Tax Compliance documentation describes tax determination, product-level tax rules, reporting, and tax codes from more than 12,000 jurisdictions.
These capabilities are particularly relevant to B2B companies managing tax-exempt customers, multiple legal entities, or complex product classifications. Exemption certificate management is identified as a Shopify Plus capability. Multi-entity tax routing also has Shopify Plan and Shopify Payments eligibility requirements, which should be verified before implementation.
Category: Tax calculation and compliance
Price Range: Contract pricing
Public Review Signal: No customer-review score
Features Included: Tax calculation, tax codes, nexus monitoring, exemption management, reporting, filing, and remittance
| Summary of Online Reviews |
|---|
| The reviewed Avalara and Shopify pages did not provide a usable customer review quote for this comparison. |
Akeneo PIM App, for Product Information Management
Akeneo is suited to merchants with structured product catalogs managed in Akeneo Product Cloud. A product information management system centralizes product attributes, specifications, media, and related catalog data before publishing it to Shopify.
The official Akeneo PIM App listing describes:
- Flexible data mapping
- Product, variant, and price synchronization
- Scheduled synchronization
- Metafields
- Media import
Akeneo’s Shopify documentation explains how the app links PIM products with existing Shopify products and updates Shopify fields.
This setup helps manufacturers and distributors maintain consistent product information across storefronts and other sales channels. Catalog governance should be established before launch because poor source data can move errors into every connected channel.
Category: Product information management
Price Range: Free to install; additional charges may apply
Public Review Signal: 5.0/5 from 1 Shopify review. The small sample limits the significance of the score.
Features Included: Product and variant synchronization, price synchronization, scheduled synchronization, data mapping, metafields, media import, multi-channel publishing, B2B catalog assignment, and job reporting
| Summary of Online Reviews |
|---|
| The Shopify listing contains only one review, so the 5.0/5 score has limited evidentiary value. The available feedback says, “The Akeneo to Shopify app has helped us streamline product updates on our store.” Akeneo Shopify App listing |
HubSpot Shopify Data Sync, for CRM and Customer Data
HubSpot connects Shopify customers, products, orders, abandoned checkouts, and company data with HubSpot’s CRM and marketing tools. The HubSpot marketplace listing describes:
- Configurable field mappings
- Historical data synchronization
- Segmentation
- Reporting
- Automated campaigns
Contacts and products can synchronize bidirectionally. Orders and abandoned checkouts synchronize one-way from Shopify to HubSpot. A marketplace review separately mentioned the absence of an abandoned cart object. This may be distinct from abandoned-checkout synchronization, so object coverage should be confirmed during implementation.
Company synchronization is plan-dependent, and the reviewed materials identify Shopify Plus as a requirement. Custom field mappings require the relevant HubSpot Operations Hub subscription. These requirements should be checked against the current Shopify and HubSpot documentation.
Category: CRM and customer data
Price Range: Requires a paid Shopify plan (Basic, Shopify, or Advanced); HubSpot subscription charges also apply
Public Review Signal: 2.3/5 from 55 HubSpot marketplace reviews
Features Included: Customer and product synchronization (two-way); order and abandoned checkout synchronization (one-way from Shopify); company synchronization (Shopify Plus only); segmentation, reporting, and marketing automation
| Summary of Online Reviews |
|---|
| One customer described the integration as “Good intuitive sync,” but added that the absence of an abandoned cart object was a limitation. The review reflects a useful setup with gaps in object coverage, which matters for teams with detailed CRM reporting requirements. HubSpot marketplace reviews |
Gorgias, for Customer Support
Gorgias centralizes customer conversations and Shopify order context within a single helpdesk. Its Shopify listing includes AI support, customer profiles, order assistance, live chat, email, social, voice, and SMS.
For B2B merchants, Gorgias can help support teams answer questions about:
- Order status
- Delivery
- Returns
- Account activity
Its strongest contribution sits in customer service operations, while product, inventory, pricing, and ERP data remain in their respective systems.
The product information states that live Shopify cart visibility was removed in November 2025. This is a material limitation for support teams that need to view an active cart.
Category: Customer support
Price Range: From $10/month; free trial available
Public Review Signal: 4.2/5 from 616 Shopify reviews
Features Included: Helpdesk, AI support, customer profiles, order assistance, live chat, email, social, voice, and SMS
| Summary of Online Reviews |
|---|
| A verified Shopify review from Grow Fragrance said, “We switched over about a year ago and really enjoy Gorgias! The AI agent has been amazing for our team, and it seems like they’re continuing to make aggressive improvements to it.” A five-year customer from VIOLETTE_FR added, “The CS is always helpful, and the AI Agent is a game changer.” Critical reviews flag a white-glove onboarding experience that did not meet expectations, as well as the November 2025 removal of live cart visibility.

Shopify Flow, for Workflow Automation
Shopify Flow is a free automation platform for tasks inside Shopify and across connected apps. Shopify’s Flow documentation explains that merchants create workflows using triggers, conditions, and actions.
Flow supports templates and connections for:
- Inventory
- Fulfillment
- Fraud prevention
- B2B workflows
- Slack
- Google Sheets
- Klaviyo
B2B teams can use it to tag wholesale orders, flag high-value customers, alert staff about inventory conditions, route orders for review, or trigger internal notifications.
Category: Workflow automation
Price Range: Available at no additional app charge for eligible Shopify plans
Public Review Signal: 4.7/5 from more than 11,800 Shopify reviews
Features Included: Triggers, conditions, actions, templates, inventory automation, fulfillment automation, B2B workflows, and app connections
| Summary of Online Reviews |
|---|
| A verified Shopify review said, “Shopify Flow is a powerful and practical tool once you get the hang of it… Great app, easy to use, and great for speeding up processes.” Other feedback praises the free price and workflow templates, while reviewers who build more complex workflows note a learning curve before the app’s full value becomes accessible.

Boost AI Search & Filter, for Product Discovery and Search
Boost AI Search & Filter is suited to B2B merchants with large catalogs, high SKU counts, or complex product attributes where buyers need precise search and filtering tools to navigate the storefront efficiently. The Shopify App Store listing describes AI-powered search that understands customer intent, product filters configurable on any page, visual merchandising rules, product recommendations, and analytics.
For B2B operations, effective search and filtering are particularly important when buyers need to locate specific parts, materials, or products across thousands of SKUs. Filtering by attributes such as brand, category, technical specification, or metafield can reduce friction and improve order accuracy. Boost AI Search & Filter sits alongside Akeneo in the product data layer: Akeneo structures and synchronizes product information, while Boost enables buyers to search and filter that catalog at the storefront.
Category: Product discovery and search
Price Range: From $29/month; free trial available
Average App Score: 4.8/5 from 1,496 Shopify reviews
Features Included: AI search, product filters, visual merchandising rules, product recommendations, analytics, and multi-language and multi-currency support
| Summary of Online Reviews |
|---|
| A verified Shopify review said, “Boost AI Search & Discovery helps us organise a very large catalogue of craft products. We have thousands of products across many different brands and categories, so effective search and filtering are essential. It makes it much easier for customers to find exactly what they’re looking for by filtering products by brand, theme, colour, range, and other attributes.” Ted Baker.ae, a four-year customer, added, “I recommend Boost for its ease of use and features that cover every merchandiser’s need… The tool is handy, reliable and provides accurate analytics.” Boost AI Search & Filter reviews |
How to Choose the Best Shopify Integrations for B2B eCommerce
The right integration starts with a workflow map. Before selecting an app or connector, document where each system stores:
- Company accounts and locations
- Buyer contacts and customer records
- Contract, tiered, or negotiated pricing
- Product specifications and catalog attributes
- Inventory by warehouse or fulfillment location
- Purchase orders, invoices, and payment status
- Shipping rates, delivery dates, and freight options
- Tax exemptions and jurisdiction rules
- EDI documents and retailer requirements
- Support tickets and account history
- Internal alerts and approval workflows
A connected stack also needs clear ownership of business rules. The ERP may control inventory and contract pricing, while ShipperHQ calculates delivery options and Shopify displays the final checkout experience. Defining those responsibilities before implementation helps reduce conflicting data and manual corrections. Atwix’s B2B eCommerce agency services support manufacturers, distributors, and complex B2B organizations in building connected commerce stacks that align with their business operations.
Before implementation, define:
- Which system is the source of truth for each data type
- Which data requires one-way or bidirectional synchronization
- How errors and failed syncs will be monitored
- Which teams approve pricing, tax, catalog, and fulfillment changes
- Which workflows require Shopify Plus or another paid platform
- Which costs are app fees, platform fees, subscription fees, or implementation fees
Choosing the Right Shopify Integration by Workflow
The appropriate integration depends on the operational problem being solved:
- Shipping complexity: ShipperHQ is designed for shipping rates, freight, delivery promises, and checkout rules.
- ERP and back-office synchronization: Sirius supports synchronization across ERP, CRM, pricing, inventory, orders, and fulfillment.
- EDI and retailer compliance: SPS Commerce handles document exchange, retailer orders, inventory visibility, and partner connectivity.
- Tax compliance: Avalara supports tax calculation, reporting, filing, remittance, and exemption workflows.
- Product data: Akeneo helps centralize structured product information before publishing it to Shopify.
- CRM and customer data: HubSpot connects commerce activity with sales, marketing, segmentation, and reporting.
- Customer support: Gorgias centralizes support conversations and the Shopify order context.
- Workflow automation: Shopify Flow automates repeatable tasks inside Shopify and across connected apps.
These tools can work together as parts of a broader commerce architecture. For example, a B2B merchant might use Akeneo for product data, an ERP connector for pricing and inventory, ShipperHQ for delivery calculations, Avalara for tax, Gorgias for support, and Shopify Flow for internal alerts.
B2B Shopify Integration Consultation
The best Shopify integration project should begin with a documented workflow map, system-of-record decisions, data ownership rules, and implementation requirements.
Because the integrations in this guide solve different problems, they are organized by use case rather than ranked overall. The right choice depends on the merchant’s systems, operating model, budget, and level of complexity.
