It’s 8 PM on a Tuesday, and instead of planning your next product launch, you’re manually re-typing order details from your Shopify store into an accounting spreadsheet, praying you don’t make a typo. For many growing businesses, this struggle isn’t a sign of failure, it’s a sign of success. Your sales are simply outgrowing your manual processes.
This gap between your customer-facing storefront and your internal operations is the root cause of countless errors and wasted hours. The solution is a process called “integration,” which builds a secure, digital bridge between your systems. Connecting Epicor Kinetic and Shopify does far more than eliminate late-night data entry. It ensures your website’s inventory is always accurate, helps your team ship orders faster, and provides a crystal-clear view of your business’s financial health.
By the end of this guide, you’ll understand exactly how this integration works, what data flows between the two platforms, and how to determine whether it’s the right move for your operation.
While Shopify excels as your customer-facing storefront, it wasn’t designed to run your entire company. As a business grows, the complexity behind the scenes in your warehouse, accounting, and production, grows even faster. You begin to feel the strain of using separate spreadsheets and disconnected software to track inventory and manage financials.
To handle that complexity, growing businesses turn to an Enterprise Resource Planning (ERP) platform. Think of Epicor Kinetic as the central brain for your entire operation.
According to Epicor’s official product page, Kinetic is “a global cloud ERP solution designed for and with manufacturers, helping them maximize profitability with real-time business intelligence and built-in collaboration tools.” It’s built for discrete and make-to-order manufacturing, with capabilities spanning supply chain management, production planning, financial reporting, and CRM, all from a single, cloud-based platform.
While Shopify manages the sale, Epicor Kinetic manages everything after the “buy” button is clicked: it updates your financial records, manages inventory across multiple locations, and coordinates your supply chain. The need for this becomes urgent when you can no longer get a single, accurate view of your business. If you’re managing multiple warehouses, assembling products from different components, or spending days reconciling sales data with your accounting books, you’ve likely outgrown a Shopify-only operation.
What happens when your Shopify store shows 10 items in stock, but your warehouse manager knows there are only 8? This common discrepancy is the direct result of disconnected systems. When your storefront and your operational brain don’t communicate, you end up with multiple, conflicting versions of the truth, leading to overselling, inaccurate financial reports, and a poor customer experience.
The solution is to establish a “Single Source of Truth.” This is the core benefit of a Shopify ERP integration. The integration builds a secure, digital bridge between the two platforms, with Epicor Kinetic acting as the master record for all critical business data. Any update in Epicor, like a new shipment arriving or a price change is instantly and automatically reflected on your Shopify site.

This consistency eliminates guesswork and empowers you to make strategic decisions with complete confidence, knowing your data is accurate across your entire business.
When you ask what data syncs between Epicor and Shopify, you’re asking what information passes across the digital bridge between these two systems. This is made possible by an API (Application Programming Interface) essentially a dedicated messenger that instantly and accurately relays information between your two platforms without any manual effort.
Data Conflict Resolution: Epicor serves as the master record. In the rare case of a simultaneous update to the same record in both systems, ERP data takes precedence — protecting your business from data inconsistencies without any manual intervention.
While every business has unique needs, real-time data synchronization for eCommerce typically focuses on four critical areas:
Each of these flows is designed to solve a specific, costly business problem and together, they form a seamless operational loop that keeps both systems perpetually in sync.
Imagine the scenario: it’s the middle of a flash sale, and you accidentally sell 100 units of a product you only have 50 of. The fallout includes refund requests, angry customers, and hours of manual cleanup. During peak traffic periods, updates may take a minute or two to propagate — still dramatically faster than any manual process, and fully reliable under normal operating conditions.
This is precisely the problem a direct Shopify inventory sync with Epicor ERP is built to solve. With real-time integration, the moment a product is sold on Shopify, the information is sent to Epicor, which immediately deducts it from the master inventory count. That updated count is then instantly pushed back to your storefront ensuring what customers see is what you actually have.
The real power becomes clear when inventory spans multiple locations. Many businesses hold stock in a primary warehouse, physical retail stores, or a third-party logistics (3PL) centre. Epicor consolidates stock levels from all locations into one accurate, system-wide total and presents that number to Shopify. This real-time data synchronization for eCommerce ensures your website can confidently sell inventory from any location, a critical capability for both consumer and B2B eCommerce with Epicor and Shopify.
This isn’t just about accurate numbers. It’s about customer trust. When your website says an item is in stock, it truly is.
Without integration, fulfillment is often a chaotic, manual process. Order details copied from Shopify into other systems create opportunities for error at every step, a blue shirt can easily become a red one with a single typo, leading to costly returns.
The connection between Epicor and Shopify changes this entirely. The moment a customer clicks “Buy,” their complete, accurate order is automatically and securely handed off to Epicor. Based on configurable rules, Epicor can route that order to the warehouse closest to the customer, or redirect fulfillment to a retail location if the main warehouse is out of stock.
This ability to streamline order management with Epicor and Shopify means every order is handled in the most efficient way possible, without manual intervention. By automating order processing with Epicor, you reclaim hours previously lost to data entry while simultaneously reducing the shipping errors that erode customer trust and inflate support costs.
Accurate order and inventory data does more than speed up shipping. It gives you financial clarity. Without a connected system, profitability is often guesswork, derived from outdated spreadsheets and delayed month-end reports.
One of the most transformative benefits of integrating Epicor with Shopify is real-time financial intelligence. When an order is placed, the integration doesn’t just notify your warehouse, it tells your financial system exactly what was sold, for how much, and to whom, in real time.
Because Epicor knows not only the sale price but also the true cost of a product including materials, labour, and logistics. It can calculate actual margin at the point of sale. This means you can finally answer critical strategic questions with confidence: Once your cost accounting is configured in Epicor, this financial visibility is surfaced automatically opening a conversation about margin optimization that manual processes simply can’t support.
The dreaded month-end close, which can consume days of manual reconciliation, becomes a simple review exercise. Your finance team shifts from hunting for numbers to analysing them strategically, a meaningful step toward the operational efficiency that executive leaders are ultimately seeking.
Understanding the benefits is one thing. Knowing how to connect Epicor Kinetic to Shopify in practice is another. The process typically follows one of two paths, and the right choice depends on your business’s complexity, workflows, and budget.

Option 1: Pre-Built Connectors
Think of this as renting a universal translator. Pre-built connectors are ready-made tools from integration platforms designed to link popular software combinations, including Epicor and Shopify. These tools, often built on iPaaS (Integration Platform as a Service) middleware, are faster to deploy and more cost-effective for businesses with standard workflows.
For example, third-party platforms offer managed Epicor Kinetic-Shopify connectors that typically sync customers, products, inventory quantities, price lists, shipment records, and orders between the two systems. This Epicor integration middleware approach is ideal for businesses that want a proven, low-risk path to integration without extensive development work.

Option 2: Custom Development
This is the equivalent of hiring a team to build a bespoke bridge, engineered precisely to your specifications. Custom API development offers maximum flexibility for unique workflows, complex pricing rules, non-standard product configurations, or multi-system orchestration, but requires a larger upfront investment.
Deciding between an Epicor integration middleware vs. custom API approach comes down to your operational reality. If your workflows are relatively standard, a pre-built connector delivers faster ROI. If your manufacturing processes are highly unique, custom development ensures the integration is built exactly to your company’s blueprint.

You’ve now seen a clear picture of what’s possible when your Shopify store and Epicor Kinetic work in concert. To determine whether integration is the right strategic move right now, use this checklist in your next team meeting:
If your answers reveal friction at multiple points, the business case for integration is strong. You’re not just fixing today’s data entry problems you’re building a scalable, resilient operational foundation for tomorrow’s growth.
The primary benefit is operational efficiency through a “Single Source of Truth.” When Epicor and Shopify are connected, critical business data, including inventory levels, orders, product details, and fulfillment status, is automatically synchronized between the two systems in real time. This eliminates manual data entry, reduces errors, prevents overselling, and provides accurate, up-to-the-minute financial reporting.
Not necessarily. Two main options exist: pre-built connectors (offered by integration platforms that provide ready-made Epicor-Shopify sync tools) and custom API development. Pre-built connectors are faster to deploy and cost-effective for standard workflows. Custom development is recommended for businesses with complex or unique operational requirements, such as specialized manufacturing processes or non-standard pricing logic.
Common integration points include customers, product listings, inventory quantities, price lists, shipment records, and orders. The most critical flows involve Shopify orders automatically creating sales records in Epicor and Epicor inventory levels updating Shopify in real time to prevent overselling.
The timeline depends on the approach and complexity of your requirements. Pre-built connector implementations can often be configured and deployed in a matter of weeks, while custom API integrations may require a longer development and testing phase. Working with an experienced agency like MageMontreal allows you to establish a realistic timeline during the discovery phase before any development begins.
Yes. A Shopify ERP integration with Epicor Kinetic is particularly well-suited for B2B eCommerce scenarios that involve customer-specific pricing, complex order types such as purchase orders and invoices, multi-location inventory, and quote-to-order workflows. Epicor Kinetic’s native B2B functionality, combined with Shopify’s B2B features, creates a robust foundation for wholesale and distributor-facing storefronts.
A Note on Advanced B2B Requirements: Complex B2B requirements — such as multi-level approval workflows or highly customized account hierarchies — may require Shopify’s B2B plan or Adobe Commerce to implement fully. We’ll identify the right platform for your needs during the discovery phase.
