How to Set Up the Acumatica-Shopify Connector (Complete Guide)
What Is Acumatica?
Acumatica is a modern, cloud-based ERP (Enterprise Resource Planning) platform designed for growing businesses. It provides connected modules for finance, inventory, distribution, CRM, manufacturing, and commerce. Because it runs entirely in the cloud and offers flexible customization options, Acumatica serves as a scalable central system of record for operations.
Key benefits of Acumatica include:
A single, unified database for all departments
Flexible workflows and customization options
Strong API support for integrations
Cloud-based access with unlimited users
Reliable tools for reporting, analytics, and automation
Acumatica's native Shopify integration builds on this foundation, giving merchants a seamless way to connect their eCommerce operations with ERP data.
Connecting Shopify to Acumatica gives merchants a centralized source of truth for inventory, financials, fulfillment, and customer data. If your business already runs on Shopify, the Acumatica Cloud ERP app in the Shopify App Store is the official, free, and fully supported way to integrate the two platforms.
This guide walks you through how to install and configure the app, what it syncs, and best practices for a clean setup.
The Official Acumatica Shopify App: Acumatica Cloud ERP
Acumatica provides a fully native Shopify integration through the Acumatica Cloud ERP app, available free in the Shopify App Store.
What the App Does
The Acumatica Cloud ERP app enables real time, bidirectional sync between Shopify and Acumatica, allowing you to manage:
Orders
Inventory
Payments
Returns
Shipments
Products
Financials
Because the integration is built and maintained by Acumatica, it fits a wide range of workflows for both B2C and B2B environments.
Key Advantages
Exports inventory from multiple warehouses and retail locations
Automates order imports and fulfillment updates
Syncs payments and refunds
Allows multiple Shopify stores to connect to one Acumatica instance
Eliminates manual entry and reduces errors with automated synchronization
This is the version of the connector merchants should use today.
Prerequisites
You will need:
An active Shopify store
Admin access to Acumatica ERP
API credentials generated during app setup
The Acumatica Cloud ERP app installed in Shopify
Step 1: Install the Acumatica Cloud ERP App in Shopify
Go to the Shopify App Store
Search for Acumatica Cloud ERP
Click Install
Approve requested permissions
After installation, Shopify will generate the required credentials and present connection settings
Step 2: Configure the App and Connect Acumatica
Once installed, the app guides you through providing your Acumatica instance details.
Open the Acumatica Cloud ERP app in Shopify
Enter:
Acumatica site URL
Tenant name
Username and password for your integration user
Confirm connection
Shopify provides your Admin API access key which you paste into Acumatica if needed
Step 3: Map Product and Variant Data
The official connector supports a flexible product syncing process.
Important Configuration Points
SKU matching: Shopify variants sync best when SKU values map one to one to Acumatica stock items.
Variant structure: Shopify’s native variant model maps cleanly to configurable stock items in Acumatica.
Multi warehouse inventory: If you use Shopify Locations, map each Shopify location to an Acumatica warehouse for more accurate availability.
Step 4: Set Up Order Import Behavior
The Acumatica Cloud ERP app automatically imports orders in near real time.
Ensure these settings align with your business:
Default order type in Acumatica
How payments are imported
Whether Shopify or Acumatica controls tax calculation
How discount codes and gift cards are handled
Since Shopify includes native discount code and gift card tools, the connector simply imports the resulting values without any extra configuration.
Step 5: Configure Fulfillment Sync Settings
The official app supports:
Shipment confirmations
Tracking number sync
Partial fulfillment
Complete fulfillment
Multiple warehouse scenarios
If you already use Shopify’s native shipping label tools, you can allow Shopify to manage labels while Acumatica manages inventory and shipment finalization
Step 6: Enable and Adjust Sync Schedules
Inside Acumatica, you can schedule or manually trigger syncs for:
Inventory
Orders
Shipments
Refunds
Products
Many merchants keep inventory syncing frequently so Shopify customers always see accurate availability.
Best Practices for a Smooth Integration
Rely on Shopify’s built-in features before adding apps: Shopify provides powerful native tools for discounting, gift cards, locations, and workflows. Third‑party apps should be added only when Shopify’s built‑in capabilities are not enough.
Use n8n for cross-platform automation: For workflows that need to connect Shopify, Acumatica, email, marketplaces, or other systems, n8n is a flexible automation platform that can run fully under your control.
Maintain disciplined SKU management: Consistent SKU values across the two systems keep product syncing clean and prevent mismatches.
Test with a few products first: Import a small number of items and orders before you enable syncing for the entire catalog.
Regularly review sync logs: Acumatica provides detailed synchronization logs, which are helpful for identifying missing data or mismatched fields.
Common Issues and Fixes

Check:
SKUs match
Stock items are active

Conclusion
The Acumatica Cloud ERP app is the fastest and most reliable way to connect Shopify and Acumatica. With real time, bidirectional syncing and support for multiple warehouses, payments, refunds, and B2C or B2B workflows, it creates a unified source of truth for your eCommerce and ERP systems.
