Epicor integrates with Shopify, but not out of the box. Without a real-time connection between your Epicor ERP and Shopify Plus storefront, your ops team becomes the integration. Pricing changes in Epicor sit unsynced. Orders placed in Shopify take hours to appear in Epicor. Inventory quantities drift. The gap between your systems becomes the bottleneck in your B2B operation. Uncap builds real-time, bidirectional Epicor Shopify integration for B2B manufacturers and distributors. One operational platform. One source of truth. Epicor stays in charge of pricing, customers, and inventory. Shopify Plus handles the buyer experience. We make them work as one.
Why Epicor Shopify Integration Fails Without a Real-Time Connection
Epicor is purpose-built for manufacturers and distributors. It manages customer-specific pricing, inventory at location level, order fulfillment routing, and the customer hierarchy that determines what each account can see and buy. It is exactly the system a complex B2B operation needs.
Shopify Plus is the buyer-facing layer your customers interact with. It is where they browse, configure orders, confirm pricing, and check out. For B2B, it handles company accounts, net payment terms, and gated storefronts.
The problem is the gap between them. By default, Epicor and Shopify operate as separate systems. You connect them with a batch sync, a middleware platform, or a scheduled export, and then you spend operational energy managing the interval between when data changes in one system and when it appears in the other.
Here is what a disconnected Epicor Shopify environment actually looks like at scale.
Your pricing team updates a customer-specific contract price in Epicor on Monday morning. Shopify picks it up that evening during the scheduled sync. In between, a buyer logs in, sees the old price, places a $40,000 order, and your ops manager has to call them to explain the discrepancy.
Your Epicor inventory shows 214 units on hand. Shopify is syncing every four hours, so it shows 312, the number from this morning's sync, before the 3pm warehouse allocation ran. A buyer orders 100 units. You are oversold.
A new account comes in with net 60 payment terms. Their terms are in Epicor. Shopify does not know them, so they hit the standard checkout. Your sales rep catches it the next day. The order ships before finance does.
This is not an Epicor problem. This is not a Shopify problem. This is what happens when two systems that should be one are separated by a sync schedule.
The Real Cost of Epicor and Shopify Running as Separate Systems
The visible cost is predictable: staff hours spent manually reconciling orders, pricing errors that require correction, fulfillment delays caused by stale inventory data. B2B manufacturers we work with typically absorb 10 to 20 hours per week in operational overhead that traces directly to the disconnect between Epicor and their Shopify storefront.
The invisible costs compound differently.
Your B2B buyers cannot trust the storefront. If a buyer has ever seen the wrong price in your Shopify storefront, a price that was not their contract price, or a price that had not been updated since last quarter's negotiation, their confidence in self-service is gone. They call their rep before every significant order. They email to confirm availability. A B2B portal that buyers cannot trust does not reduce inside sales workload. It adds to it.
Order-to-fulfillment latency compounds the problem. A real Epicor Shopify integration means an order placed in Shopify at 4pm is in Epicor's fulfillment queue at 4pm. Without real-time sync, there is a window, sometimes hours, where the order exists in Shopify but has not been acknowledged by Epicor. During that window, inventory is not reserved, fulfillment has not started, and if your ops team is not monitoring the queue manually, it does not move.
Customer hierarchy and credit enforcement gaps create financial exposure. Epicor manages your customer credit limits, payment terms by account, and purchase authorization rules. None of that travels to Shopify automatically. Without an integration that maps Epicor's customer data model to Shopify's B2B infrastructure, buyers can exceed their credit limits at checkout, accounts with overdue balances can place new orders, and payment terms show incorrectly on invoices.
The middleware tax is real. Many Epicor Shopify integrations are built on middleware platforms, Boomi, Celigo, Alumio, or similar. These platforms require ongoing subscriptions, vendor-specific training, and someone on your team who owns the integration. When Epicor updates or Shopify changes an API, the middleware breaks. You own the fix. The integration you pay to run is the same integration you pay to maintain.
What Epicor to Shopify Integration Actually Changes
Real-time Epicor Shopify integration means both systems operate from the same data. An order placed in Shopify immediately creates an Epicor order with full line-item detail, customer data, and delivery preferences. Inventory adjusted in Epicor is reflected in Shopify within seconds. Pricing changes in Epicor, contract prices, volume tiers, promotional rates, appear in Shopify instantly. Customer credit limits, payment terms, and company hierarchies enforced in Epicor are enforced in Shopify's checkout automatically.
Your buyers see accurate data every time: their price, their inventory, their terms. Your ops team works from Shopify and Epicor as a single operational platform, not two systems they reconcile at the end of the day.
Most Epicor Shopify integrations route data through a third-party middleware layer that you subscribe to, train on, and maintain. When either platform updates, the middleware may break and you own the remediation. Uncap builds a clean, maintainable integration architecture that connects Epicor directly to Shopify Plus using Shopify's native B2B infrastructure. We map Epicor's data model, customer hierarchies, pricing matrices, inventory locations, order routing, to Shopify's company accounts, catalogs, and payment term features. We build sync logic that keeps systems current without middleware subscriptions or manual intervention. We design the workflows so your team can operate from Shopify without ever needing to dive back into Epicor for routine B2B tasks.
We have done this for [CUSTOMER PROOF — request from brand team] B2B businesses. We know where Epicor integrations break, pricing matrix edge cases, multi-location inventory, company hierarchy sync, and we build specifically to prevent it.
The integration is the foundation. What you run on top of it is the Revenue Engine.
Once Epicor and Shopify Plus are connected in real time, Uncap's Revenue Engine drives what comes next. Dealroom accelerates quote-to-cash through digital quoting and collaborative negotiation between buyers and sellers. Advanced Product Configurations manages complex pricing and product configuration without manual overhead. The Self-Serve Portal gives your B2B buyers a 24/7 ordering experience embedded inside your Shopify storefront, fed by live Epicor data. Advanced Quote Management takes you from quote to confirmed order without coordination friction. Smart Agents surface upsell, reorder, and margin recommendations automatically.
Integration connects your systems. The Revenue Engine is what makes them perform together.
What We Build During Your Epicor Shopify Integration
Capability 1: Real-Time Inventory Sync
Shopify's inventory quantities sync bidirectionally with Epicor at the location level. When a buyer orders in Shopify, inventory is decremented in Epicor immediately, not on the next scheduled run. When inventory is adjusted in Epicor, Shopify reflects it within seconds. No manual syncs. No over-commits caused by stale data.
Capability 2: Pricing and Payment Terms Sync
Customer-specific pricing, tiered pricing, volume discounts, and payment terms, net 30, net 60, net 90, all flow from Epicor into Shopify's B2B infrastructure. Price changes happen once in Epicor and are live in Shopify instantly. Your buyers always see the correct price for their account. No manual price sheet updates. No pricing discrepancies on orders.
Capability 3: Customer Hierarchy and Credit Limit Enforcement
Company accounts, customer hierarchies, and credit limits from Epicor are mapped directly into Shopify's company account architecture. Shopify's checkout enforces credit limits and payment terms pulled from Epicor in real time. Buyers cannot exceed their credit limit or check out against terms that have not been approved by your finance team.
Capability 4: Order Sync from Shopify to Epicor
Orders placed in Shopify create Epicor orders immediately, with full line-item detail, customer account data, delivery preferences, and any custom field your Epicor order workflow requires. Your fulfillment team sees the order in Epicor's queue and starts picking without waiting for a sync window.
Capability 5: Catalog and Product Data Sync
Product master data, pricing, availability, and attributes flow from Epicor into Shopify's product catalog. High-SKU operations, manufacturers with thousands of part numbers across multiple catalogs, stay synchronized without manual data entry or PIM overhead. Epicor P21 and Epicor Kinetic both supported.
Capability 6: Real-Time Operations Without Manual Intervention
Your operations team does not manage the integration. They work from Shopify. The sync architecture handles reconciliation, error management, and data integrity behind the scenes. When something fails, the integration alerts your team before it becomes an order problem.

Frequently Asked Questions
Does Epicor integrate with Shopify?
Yes, Epicor integrates with Shopify, but not natively, the connection requires a custom integration built by a Shopify development partner with expertise in both Epicor's data model and Shopify Plus's B2B infrastructure. Epicor does not have a built-in Shopify connector. What most B2B manufacturers use is either a middleware platform (Boomi, Celigo, Alumio) or a custom-built integration that maps Epicor's customer hierarchies, pricing, and inventory structures to Shopify's company accounts, catalogs, and payment terms. Uncap builds custom Epicor to Shopify integrations for B2B manufacturers and distributors, with real-time bidirectional sync and no middleware subscriptions.
What ERP systems integrate with Shopify?
Shopify Plus integrates with all major ERP systems, including Epicor, NetSuite, SAP, Microsoft Dynamics, and Oracle, through custom-built or middleware-based integration architectures. Shopify does not have native ERP integrations built in, but its API and B2B infrastructure, company accounts, customer-specific pricing, payment terms, and purchase order support, are designed to receive and serve data from ERP systems. The quality of the integration depends on whether it is built with real-time sync or batch sync, how deeply it maps the ERP's data model to Shopify's B2B features, and who owns the maintenance. Uncap builds real-time ERP integrations for Shopify Plus with a focus on B2B manufacturers and distributors.
What is Epicor Shopify integration?
Epicor Shopify integration is a real-time, bidirectional connection between your Epicor ERP and Shopify Plus storefront that synchronizes inventory, pricing, customer data, orders, and payment terms without manual intervention. For B2B manufacturers and distributors, this integration replaces disconnected systems with a single operational platform where Epicor remains the source of truth for product and customer data while Shopify Plus handles the buying experience for B2B wholesale customers.
How long does Epicor to Shopify integration take?
A standard Epicor to Shopify integration typically takes 10 to 14 weeks from kickoff to go-live, depending on the complexity of your Epicor configuration, the number of custom fields, pricing structures, and the breadth of the integration (inventory alone vs. full order-to-cash). Epicor P21 and Epicor Kinetic integrations follow similar timelines, though Kinetic's API architecture allows for faster sync configuration in some cases. Talk to our team and we will scope the timeline for your specific setup.
Will my Epicor system stay live during the integration build?
Yes, your Epicor system continues operating normally throughout the integration build. We work in a parallel Shopify environment until the integration is fully tested and validated. Your cutover plan is coordinated to minimize disruption to your operations and your buyers.
Does Shopify Plus natively support Epicor integration?
Shopify Plus does not natively integrate with Epicor, but Shopify's API architecture and B2B infrastructure are purpose-built for ERP integrations like Epicor. Uncap builds clean, maintainable integration architecture that leverages Shopify's native B2B features, company accounts, custom pricing, payment terms, and connects them to Epicor without middleware subscriptions or custom code bloat.
How much does Epicor to Shopify integration cost?
Epicor Shopify integration cost depends on the scope and the complexity of your Epicor configuration. The scope varies based on whether you need inventory and order sync only, or a full order-to-cash integration including pricing matrix sync, customer hierarchy mapping, credit limit enforcement, and catalog sync. Uncap scopes every project individually and delivers a fixed-scope, fixed-price engagement after an initial discovery call. Talk to our team to get a clear picture of what your operation needs and what it costs.
