Best ERP for Shopify (and How We Integrate It)

craftberry is a Shopify Premier Partner with 800+ Shopify projects since 2015. We've connected Shopify with Odoo, SmartERP, IQSoft, and SAP- and MuleSoft-based stacks, so we've seen where integrations fail after launch.

Key Takeaways

• ✓Shopify isn't an ERP. It manages ecommerce operations, while ERP software handles accounting, procurement, inventory, manufacturing, and other back-office processes.
• ✓The best ERP for Shopify depends on your operations. NetSuite, Microsoft Dynamics 365 Business Central, Acumatica, Odoo, and SAP are five options worth comparing.
• ✓Shopify ERP integration can use certified connectors, middleware such as Celigo, or custom API development.
• ✓Integration problems often appear after launch. Incorrect invoices, duplicate refunds, inventory discrepancies, and failed data transfers can go unnoticed without proper monitoring.
• ✓From our projects: we connected two Shopify stores to IQSoft for SiFly, co-developed a SmartERP connection for Enhance when no Shopify integration existed, and linked Shopify Plus to MuleSoft through Gadget for On Running's 11-week UAE launch.

Do you need an ERP for Shopify?

Is Shopify an ERP? No. Shopify handles ecommerce operations such as storefronts, checkout, products, and orders. ERP software manages broader business processes, including accounting, procurement, inventory, and manufacturing.

Not every Shopify store needs an ERP. From what we have seen, smaller merchants often manage daily operations with Shopify and a few dedicated tools. In our experience working with mid-sized and large Shopify brands, keeping information consistent becomes harder as a business expands across warehouses, sales channels, or legal entities.

On the integrations we are brought in to fix, teams often end up correcting orders, inventory, and accounting records manually because the systems were never properly connected.

A Shopify ERP integration automates these processes. In our opinion, the right setup depends more on how your business operates than on which ERP has the longest feature list.

What is the best ERP for Shopify?

The best ERP for Shopify depends on what you're selling, where you operate, and which processes need to work together.

Three of these options, NetSuite, Business Central, and Acumatica, have connectors listed in Shopify's Global ERP Program. The program also includes Brightpearl and Infor. Odoo and SAP can connect through other integration solutions.

How we evaluated these ERP systems

We selected these five platforms based on their relevance to Shopify integration projects for mid-sized and large brands and their available integration options.

For every ERP, we reviewed the integration options available today: listings in Shopify's Global ERP Program (checked October 2026), the vendor's own connector documentation, and middleware support.

Where we have delivered integrations ourselves (Odoo and SAP-based stacks), we added what we learned on those projects. No ERP vendor paid to be included or influence its position.

This guide is published by craftberry, a Shopify Premier Partner that builds custom ERP integrations.

1. Oracle NetSuite: best for complex financial operations

NetSuite combines accounting, inventory, procurement, and order management in a cloud ERP.

It's a strong option for businesses managing multiple subsidiaries, currencies, or sales channels that need consolidated financial reporting.

Shopify integration: NetSuite has a certified Shopify connector. Middleware such as Celigo can also support more complex data flows.

What to check: Whether the integration covers your financial processes, custom fields, and inventory requirements without extensive additional development.

2. Microsoft Dynamics 365 Business Central: best for Microsoft-based businesses

Business Central brings financial management, purchasing, inventory, and sales operations into Microsoft's business software ecosystem.

It is a practical choice for companies already relying on Microsoft products, particularly when financial and inventory operations need to connect with ecommerce.

Shopify integration: Microsoft's Shopify Connector supports products, customers, orders, inventory, and fulfillment synchronization.

For businesses already using Microsoft ERP software, we usually recommend evaluating integration options before considering a replacement.

3. Acumatica: best for distribution and manufacturing

Acumatica combines financial management with inventory, distribution, and manufacturing functionality.

If you manage inventory across multiple warehouses or have manufacturing processes to coordinate, Acumatica is worth considering.

Acumatica supports inventory-heavy operations where stock availability, purchasing, and fulfillment need to be managed alongside financial records.

Shopify integration: Acumatica has a certified Shopify connector for connecting ecommerce and ERP operations.

What to check: Product structures, location mapping, fulfillment logic, and any workflows that differ from standard order processing.

4. Odoo: best for customizable ERP workflows

Odoo provides separate applications for accounting, inventory, purchasing, manufacturing, CRM, and other business functions.

Its modular structure allows businesses to implement the functionality they need, although extensive customization can increase maintenance requirements.

Shopify integration: Third-party connectors and custom APIs can connect Odoo with Shopify.

Our experience: We've built custom Odoo ERP integrations for Takomo, a Finnish DTC golf equipment brand, and The Fashion Project, a Greek fashion brand.

For Takomo, we implemented inventory and order synchronization alongside a Shopify Plus rebuild serving 195+ countries.

For The Fashion Project, off-the-shelf ERP logic couldn't handle the brand's product structures, so we co-developed a custom inventory sync with the Odoo team, built around the brand's catalog and workflows.

These projects show why ERP integration needs to be considered alongside the wider Shopify architecture, particularly when an ecommerce business serves multiple international markets.

5. SAP: best for enterprise operations

SAP offers ERP software for businesses with advanced financial, manufacturing, procurement, and supply chain requirements.

For companies already using SAP, connecting it with Shopify may be more practical than replacing established back-office systems.

Shopify integration: Middleware, third-party solutions, or custom APIs can connect Shopify with SAP. The approach depends on the SAP product and the surrounding technology stack.

Our experience: We worked with Shelly, a global IoT and smart-home brand selling in 100+ markets.

We migrated 500,000+ customer records from Shopware to Shopify Plus and connected the store to a complex technology stack that includes SAP.

The project illustrates why enterprise Shopify development often involves more than a single ERP connection. Shopify needs to work within an existing technology environment without disrupting the systems the business relies on.

Already using an ERP?

Moving to Shopify doesn't necessarily mean replacing the software running your business.

The important question is whether your current ERP can exchange the information Shopify needs, reliably and without unnecessary manual work.

That includes more than transferring orders. Inventory, fulfillment, invoices, refunds, and customer information may all need to move between systems.

When ERP integration is part of a Shopify migration, we consider these dependencies alongside the store rebuild.

How to integrate Shopify with an ERP

There are three main approaches to Shopify ERP integration: certified connectors, middleware, and custom development.

The right option depends on how much customization your operations require.

1. Shopify's Global ERP Program

Shopify's Global ERP Program provides certified integration apps for selected ERP systems.

These can simplify common tasks such as synchronizing products, inventory, customers, and orders.

They're a good place to start when your ERP is supported. However, a certified connector doesn't mean every workflow is covered. Complex product configurations, B2B pricing, or accounting requirements may still need additional development.

2. Middleware such as Celigo

Middleware manages communication between Shopify and other business systems.

For example, Celigo offers prebuilt Shopify and NetSuite integration flows covering orders, inventory, fulfillment, and financial transactions.

Middleware can also transform data before it reaches another system, making it useful when information stored in Shopify doesn't match the structure required by the ERP.

The trade-off is another platform to configure, monitor, and maintain.

3. Custom Shopify ERP integration

A custom integration becomes relevant when an ERP has no suitable connector or existing solutions don't support the required processes.

This might involve custom product configurations, complex warehouse structures, specialized accounting rules, or older ERP software.

At craftberry, we approach custom Shopify development by evaluating existing connectors and middleware before deciding what needs to be built.

Our work with Enhauto and On Running shows two different situations where standard integrations weren't the right fit.

Enhauto: connecting Shopify with SmartERP

Enhauto, also known as Enhance Automotive, develops smart accessories for Tesla vehicles.

Its existing SmartERP system had no Shopify integration. We worked with SmartERP to co-develop a custom connection covering inventory, orders, and fulfillment edge cases.

We built the integration around the business's existing processes rather than requiring those processes to fit a standard connector.

On Running: connecting Shopify Plus with MuleSoft

For On Running's UAE launch, we used Gadget as the connection layer between Shopify Plus and MuleSoft.

The integration automates product sourcing, stock updates, order synchronization, and fulfillment data.

The full Shopify Plus store launched in 11 weeks.

Gadget is also our preferred tool for building private Shopify apps and connecting external APIs. It gives us a way to develop integration logic around the requirements of each project.

How we integrated Shopify with IQSoft ERP for SiFly

SiFly develops electric hydrofoils and sells through 130+ locations worldwide.

The company has operations in Europe, the USA, and the UAE, each with its own legal entity, tax structure, and warehouse.

When we rebuilt SiFly's ecommerce experience on Shopify, connecting the stores with its existing ERP was an important part of the project.

IQSoft manages SiFly's inventory and accounting operations. Shopify needed to work with those processes without adding manual work for the team.

Connecting two Shopify stores with IQSoft

We built a two-store Shopify architecture to support SiFly's regional operations.

Each store manages its own pricing, currencies, taxes, shipping rules, and ERP connection.

Using Gadget as middleware, we connected both stores with their corresponding IQSoft environments.

The integration automates the exchange of orders, customer data, inventory, and invoices.

Managing complex product configurations

An eFoil sold online as a single configuration may contain separate components: a board, mast, battery, and wings.

Those components need to be recognized individually by the ERP for inventory and assembly purposes.

We built integration logic that identifies the components in IQSoft and triggers the appropriate inventory and assembly processes.

This allows the operational systems to process a purchase according to the actual product structure.

The wider Shopify project also included migrating 104 products and rebuilding the shopping experience around SiFly's international operations.

The takeaway: A standard order sync wouldn't necessarily address a product structure like SiFly's. The integration needed to connect what customers buy online with how the business manages those products internally.

Common Shopify ERP integration problems

From our experience working with Shopify and back-office systems, the most difficult issues often involve information that appears to have synchronized successfully but isn't quite correct.

One-way synchronization isn't necessarily an error

Not every ERP integration needs to synchronize data in both directions.

In many of our integrations, data flows from Shopify to the ERP, but changes made inside the ERP don't automatically flow back to Shopify.

If someone manually edits a record in the ERP, the Shopify record may remain unchanged. That's expected when the integration was designed for one-way synchronization.

We define these rules before development, so teams understand which system controls each field and don't mistake expected behavior for an integration failure.

When order changes create incorrect invoices

Shopify orders can be edited after purchase. Quantities, discounts, and shipping charges may change, while the ERP still expects the original order structure.

One issue we've encountered involves shipping adjustments. When shipping is changed, the original shipping line can remain in the order data, potentially causing the customer to be billed twice.

We filter out the leftover shipping line before sending the information to the ERP and recalculate relevant discounts based on the updated order.

VAT validation also needs attention. A VAT number can expire between the order and invoice creation, so we re-check it immediately before issuing the invoice and flag the record if validation fails.

Refund events need to be handled exactly once

A refund event can be triggered more than once.

Without protection against duplicate processing, an integration may create multiple credit notes for the same refund.

We design credit-note processing so repeated events don't create duplicate financial records.

Full refunds also require more attention than simply reversing the product amount. Shipping charges and, on international orders, customs duties need to be handled explicitly.

If a credit note can't be created, we tag the Shopify order and email the team so the failure doesn't disappear unnoticed.

Store credit needs its own accounting logic

Some ERP systems don't have a direct equivalent of Shopify store credit.

When Shopify issues a refund as store credit, there isn't a conventional payment to reverse. Standard invoice and credit-note logic may therefore produce incorrect accounting records.

On one project, we mapped the possible store-credit scenarios, including cases where a customer paid for a new order partly with store credit and partly with a new payment.

We defined how each scenario should be represented so the accounting remained balanced.

Inventory synchronization can fail because of one record

An entire nightly inventory update can fail because one outdated record remains in the synchronization batch.

In our experience, removing the problematic record can resolve the issue without changing the rest of the integration.

We've also encountered synchronization failures where integration logs contained no errors. In those situations, the problem often sits on the Shopify side rather than in the connection itself.

Why increasing a timeout doesn't always help

When an on-premise ERP doesn't respond, the first assumption may be that the system is too slow.

But in our experience, a hanging request is often caused by a firewall or an allowed-IP list blocking communication.

Increasing the timeout won't resolve a blocked connection.

We check network permissions first, before treating the problem as a performance issue.

How craftberry approaches Shopify ERP integration

We start with the business process, not the connector.

Before development, we need to understand what happens from the moment an order is placed to the point where it's invoiced, fulfilled, and reflected in inventory.

Our approach follows five stages.

1. Map the data flows

We establish which system owns each type of information and where updates need to go.

Order, inventory, customer, and financial records may each require different synchronization rules. We also establish whether updates are one-way or two-way.

2. Choose the integration architecture

We assess whether an existing connector, middleware, or custom development can support the requirements without unnecessary complexity.

Our experience with Odoo, SmartERP, IQSoft, and larger enterprise stacks helps us evaluate which approach fits the existing infrastructure.

3. Build and test individual workflows

Rather than treating the integration as one large connection, we validate its stages separately. For example:

Order → Invoice → Shipping label → Tracking → Inventory update

The exact sequence and direction of data flows depend on the business.

4. Test real operational scenarios

We use isolated development environments and test stores to avoid affecting live fulfillment.

Testing covers more than straightforward orders. We also check edits, refunds, store credit, missing SKUs, VAT validation, warehouse mapping, and other scenarios that can cause discrepancies.

5. Monitor and reconcile after launch

We verify that records remain consistent and make sure failed transactions can be identified and investigated.

For businesses managing wholesale operations, these requirements may also involve customer-specific pricing, company accounts, and B2B ordering workflows. Our Shopify B2B development services cover these additional requirements.

How much does Shopify ERP integration cost?

There's no fixed price for Shopify ERP integration. The cost depends on the systems involved, the workflows that need to be connected, and how much development is required.

The main cost factors are:

• ✓ERP and connector licenses: Subscription fees and vendor-specific costs.
• ✓Integration complexity: Number of stores, warehouses, and data flows.
• ✓Custom development: Business logic not covered by existing connectors.
• ✓Testing and migration: Data validation and the transition from existing workflows.
• ✓Ongoing maintenance: Monitoring, troubleshooting, and compatibility updates.

A standard connector implementation usually requires less custom development than an integration involving multiple ERP environments, complex accounting rules, or configurable products.

However, the cheapest initial option isn't necessarily the most economical long-term solution. In our experience, a connector that requires constant manual corrections can become more expensive to operate than a properly developed integration.

How to choose the right Shopify ERP integration

Before deciding on an ERP or integration method, ask:

1. 1Which processes need to be connected? Orders and inventory only, or also invoices, refunds, fulfillment, and manufacturing?
2. 2Which system controls each record? Define where prices, stock, customer data, and financial information should be maintained.
3. 3Does an existing connector cover your workflows? Test complex scenarios, not just basic order synchronization.
4. 4What happens when something fails? Errors need to be visible, recoverable, and traceable.
5. 5Who will maintain the integration? Account for updates, monitoring, and ongoing support.

If you're already using an ERP that works well, we recommend assessing whether it can be integrated with Shopify before considering a replacement.

When you may not need an agency

If your ERP is listed in Shopify's Global ERP Program and your workflows are standard (one store, one warehouse, no custom product structures or accounting rules), the certified connector and your ERP partner may be enough.

craftberry is usually a better fit when an integration has to handle multiple stores or warehouses, configurable products, edited orders, refunds and store credit, or an ERP with no ready-made Shopify connection.
