Best Shopify ERP Integration Apps (2026)

You're copying order data into spreadsheets, manually updating inventory counts across channels, and reconciling finances at the end of each month by hand. It works when you're doing 20 orders a day. At 200, it breaks. At 500, it's costing you real money in errors, oversells, and wasted staff hours. That's when you start looking at Shopify ERP integration apps.

For most stores, the inflection point arrives somewhere between $2M and $10M in annual revenue — when manual data entry and inventory mistakes start costing more than the integration itself. If you're not there yet, bookmark this and come back. If you are, here are the best options available in 2026.

What Does Shopify ERP Integration Do?

A Shopify ERP integration app connects your Shopify store to an Enterprise Resource Planning system, automatically syncing orders, inventory, accounting, and fulfillment data between both platforms. Shopify handles your storefront. An ERP handles everything behind it.

Without integration, these systems don't talk to each other. You end up with inventory counts that don't match, financial reports that lag by days, and fulfillment teams working off outdated data. ERP integration syncs this data automatically — orders flow from Shopify to your ERP, inventory updates flow back, and financial records stay current without manual entry.

The challenge is that Shopify and ERP systems store data differently. Product structures, order formats, and customer records don't map cleanly between systems. The right integration app handles that translation so you don't have to.

How to Choose the Right Shopify ERP Integration App

Before comparing apps, answer three questions:

1. Which ERP do you use (or plan to use)? Some apps connect to one specific ERP. Others are middleware that connects to dozens. Start with your ERP, not the app.
2. What data needs to sync? Most merchants need orders, inventory, and customers. If you also need purchase orders, manufacturing, or multi-warehouse fulfillment, your options narrow.
3. What's your order volume? Some apps handle 50 orders/day without issue but choke at 1,000. API rate limits, sync frequency, and error handling matter more as volume grows.

With that context, here are the best Shopify ERP integration apps available in 2026 — verified on the Shopify App Store with real ratings and pricing.

1. Brightpearl by Sage

Brightpearl is a Retail Operating System built specifically for commerce brands. It's not a generic ERP with a Shopify connector bolted on — it was designed for retail workflows from the start.

The Shopify integration is native, meaning it doesn't require third-party middleware. Orders, inventory, purchasing, warehouse management, and accounting all sync directly. Brightpearl handles everything after the "buy" button: order routing, fulfillment logic, returns processing, and financial reporting.

• Best for: Mid-market to enterprise retailers doing $1M+ in revenue who need order management, inventory, and accounting in one system
• Pricing: Custom quotes based on order volume — expect enterprise-level pricing, but lower than NetSuite for most retailers
• Strength: Purpose-built for retail. Skips manufacturing and heavy supply chain features that most Shopify merchants don't need
• Limitation: Not ideal for stores with significant manufacturing or complex BOM (bill of materials) needs

2. NetSuite ERP Connector

NetSuite is the most widely used ERP among Shopify Plus merchants at scale. The official NetSuite ERP Connector (developed by Oracle) syncs products, pricing, inventory, sales orders, and fulfillment data between NetSuite and Shopify — including Shopify POS and B2B storefronts.

The app starts at $199.92/month on the Shopify App Store, which covers the connector only — you'll need a separate NetSuite license. Third-party NetSuite connectors from companies like Celigo and Folio3 offer alternatives with different pricing and customization options.

• Best for: Shopify Plus merchants already using NetSuite, or those planning to adopt it as their primary ERP
• Pricing: From $199.92/month for the official connector (NetSuite license is separate and starts around $999/month)
• Strength: Deep, bidirectional sync with the most comprehensive ERP on the market. Handles complex multi-entity, multi-currency setups
• Limitation: Total cost (connector + NetSuite license + implementation) makes this a $30K+/year commitment at minimum

3. Fulfil.io

Fulfil is an ERP built specifically for ecommerce and wholesale brands. It has a 5.0-star rating from 37 reviews on the Shopify App Store — the highest-rated dedicated ERP in the category.

What makes Fulfil different is scope. It handles inventory management across 400+ 3PL locations natively, includes warehouse management (WMS), and supports manufacturing workflows. Implementation typically happens in weeks rather than the months that NetSuite or SAP require.

• Best for: DTC and wholesale brands on Shopify Plus that need inventory, warehouse management, and manufacturing in one system
• Shopify App Store rating: 5.0 stars (37 reviews)
• Strength: Purpose-built for ecommerce. Faster implementation than legacy ERPs. Native 3PL integration
• Limitation: Smaller ecosystem than NetSuite — fewer third-party integrations and consultants available

4. Odoo Integration

Odoo takes a modular approach to ERP. You start with what you need — inventory and orders, for example — and add modules (accounting, manufacturing, purchasing, CRM) as your business grows. The Shopify integration app has a 4.9-star rating from 49 reviews.

Orders sync automatically from Shopify to Odoo, inventory updates in real time, and customer data flows bidirectionally. The modular design means you're not paying for features you don't use, which makes Odoo one of the more accessible ERP options for growing stores.

• Best for: Growing merchants who want to start with basic inventory/order sync and scale into full ERP functionality over time
• Shopify App Store rating: 4.9 stars (49 reviews)
• Strength: Modular pricing — pay for what you use. Open-source community edition available
• Limitation: Customization often requires developer resources. The open-source version has a steeper learning curve

5. Acumatica Cloud ERP

Acumatica is a cloud-native ERP with a strong Shopify integration — and it was the first ERP to support Shopify's B2B features natively. The connector syncs orders, inventory, payments, returns, shipments, products, and financials in real time.

Acumatica's pricing model stands out: it charges by resources used, not per user. That means your entire team can access the system without per-seat fees eating into your margins.

• Best for: Shopify merchants with B2B and DTC operations who need both channels managed in one ERP
• Strength: No per-user pricing. Native B2B support for Shopify. Strong multi-warehouse and multi-entity capabilities
• Limitation: Implementation costs are significant — expect $50K-$150K for a full rollout with a partner

6. Xorosoft ERP

Xorosoft is a cloud ERP designed for ecommerce, retail, and wholesale businesses. It has a perfect 5.0-star rating from 21 reviews on the Shopify App Store, with every single review giving it 5 stars.

The platform focuses on inventory management, order processing, and warehouse operations with a cleaner, more modern interface than legacy ERP systems. It's positioned between lightweight inventory tools and full enterprise ERPs.

• Best for: Ecommerce and wholesale businesses that have outgrown basic inventory apps but aren't ready for NetSuite-level complexity
• Shopify App Store rating: 5.0 stars (21 reviews)
• Strength: Modern UI, purpose-built for ecommerce workflows, simpler implementation than legacy ERPs
• Limitation: Smaller user base means fewer community resources and third-party integrations

7. Celigo (Middleware Approach)

Celigo isn't an ERP itself — it's integration middleware that sits between Shopify and whatever ERP you already use. It connects to NetSuite, SAP, Microsoft Dynamics 365, Sage Intacct, Acumatica, QuickBooks, and over 1,000 other systems.

If you already have an ERP and just need a reliable connector to Shopify, Celigo handles the data translation and workflow automation. It's particularly strong for merchants running complex, multi-system architectures where point-to-point integrations have become unmanageable.

• Best for: Merchants who already use an ERP and need reliable middleware to connect it to Shopify
• Strength: Works with almost any ERP. Handles complex data mapping and transformation. Pre-built integration flows for common scenarios
• Limitation: You're adding another system to manage. Costs stack on top of your existing ERP license

When You Don't Need an ERP Yet

Not every Shopify store needs ERP integration. If you're running a single warehouse, fewer than 100 SKUs, and under $500K in annual revenue, the overhead of selecting, implementing, and maintaining an ERP connection will outweigh the benefit.

At that stage, Shopify's built-in inventory management plus a lightweight accounting integration (like QuickBooks or Xero) handles most needs. If your main challenge is syncing inventory across sales channels, a dedicated inventory app may be a better fit. And if you're looking for simpler order management tools, start there before committing to a full ERP. Full ERP integration makes sense when you're managing multiple warehouses, processing hundreds of orders daily, or spending more than 10 hours per week on manual data entry between systems.

Start with the problem, not the solution. If inventory errors are costing you sales, if order fulfillment is slowing down, if your accountant is weeks behind — that's when ERP integration pays for itself. Pick the system that matches your current complexity, not where you hope to be in three years.
