The Challenge

The Cost of Disconnected Systems: Why Manual Epicor & Walmart Operations Fail

Mid-market businesses relying on Epicor ERP for their core operations often struggle to keep pace with the demands of high-volume e-commerce channels like Walmart Marketplace. Disparate systems create operational bottlenecks, data inconsistencies, and significant manual overhead, hindering growth and customer experience.

  • Manual Order Processing: Copying orders from Walmart to Epicor is slow, error-prone, and unsustainable at scale.
  • Inventory Discrepancies: Outdated stock levels lead to overselling on Walmart, resulting in cancellations, chargebacks, and frustrated customers.
  • Stale Product Information: Manually updating product listings, pricing, and descriptions across both systems is time-consuming and prone to errors.
  • Inefficient Returns Handling: Disconnected return processes delay refunds, damage seller ratings, and create reconciliation nightmares.
  • Lack of Real-time Visibility: Without unified data, making informed business decisions across sales channels is nearly impossible.

Technical Integration: Connecting Epicor and Walmart Marketplace

Our iPaaS provides robust, API-first connectivity between Epicor ERP and Walmart Marketplace, orchestrating complex data flows with intelligence and precision. We leverage the strengths of both platforms to create a resilient and scalable integration architecture.

Data Flow Steps

1. API Connectivity: Establish secure connections using OAuth 2.0 for Walmart Marketplace and OAuth 2.0/token-based authentication for Epicor Kinetic REST APIs.

2. Event/Trigger Configuration: Configure Epicor Business Process Management (BPM) or custom event publishers to trigger iPaaS workflows on key data changes (e.g., new SalesOrder, inventory update). For Walmart, utilize event-driven polling or webhooks if available, coupled with intelligent change detection.

3. Data Extraction: Extract relevant data from the source system (e.g., Walmart `Order` details, Epicor `Part` inventory) using their respective APIs.

4. AI-Assisted Mapping & Transformation: Our AI co-pilot suggests and validates data mappings. The iPaaS's visual mapping canvas allows for drag-and-drop transformation of data schemas (e.g., Walmart's `purchaseOrderId` to Epicor's `PONum`).

5. Business Logic & Validation: Apply custom business rules and data validation logic (e.g., check for valid SKUs, minimum order quantities) within the iPaaS, often with AI-generated suggestions.

6. Data Ingestion: Push transformed and validated data to the target system's API (e.g., create Epicor `SalesOrder` via POST, update Walmart `Inventory` via PUT).

7. Error Handling & Retry: Implement robust error handling, including automated retries with exponential backoff for transient issues and dead-letter queues for persistent failures, with AI-driven diagnostics.

8. Status Updates & Reconciliation: Update status back to the source system (e.g., Walmart order status) and log all transactions for audit and reconciliation.

Data Touchpoints

Walmart Marketplace: `Order`, `Item`, `Inventory`, `Price`, `Shipment`, `Return`, `Customer`
Epicor ERP: `SalesOrder`, `Part (Product)`, `Customer`, `Invoice (AR)`, `CashReceipt`, `JobHead (Production Order)`, `ShipVia`

"Walmart Marketplace (New Order) --> iPaaS (Extract, AI Map, Transform) --> Epicor ERP (Create Sales Order, Allocate Inventory) --> Epicor (Shipment Confirmation) --> iPaaS (Extract, Map) --> Walmart Marketplace (Update Order Status, Tracking). Epicor ERP (Inventory Change) --> iPaaS (Extract, AI Map, Transform) --> Walmart Marketplace (Update Inventory)."

Data Mapping

Key Entities & AI-Assisted Mapping for Epicor and Walmart Marketplace

Seamless integration relies on precise mapping of core business entities. Our iPaaS, powered by AI, simplifies this complex process by intelligently bridging the data models of Epicor and Walmart Marketplace.

Order / SalesOrder

Synchronizes customer purchase orders from Walmart Marketplace to Epicor ERP for fulfillment and financial processing.

Epicor Fields

OrderNum OrderDate CustNum ShipToNum PONum OrderAmt OrderStatus OrderDtl (PartNum, OrderQty, UnitPrice)

Walmart Marketplace Fields

purchaseOrderId customerOrderId orderDate orderStatus shippingInfo (name, address, phone) orderLines (sku, quantity, unitPrice)

Mapping Notes

Walmart's `purchaseOrderId` often maps to Epicor's `PONum` or a custom `Character01` field. Walmart `orderLines` map directly to Epicor `OrderDtl` for product details. Customer information from `shippingInfo` creates or updates an Epicor `Customer` record for the order.

  • UOM Mapping: Map Epicor's Units of Measure (UOM) to Walmart's accepted `unitOfMeasure` values.
  • Status Translation: Translate order, shipment, and return statuses between Epicor's internal codes and Walmart's public-facing statuses.
  • Address Standardization: Cleanse and standardize shipping and billing addresses to ensure deliverability and Epicor compatibility.
  • Attribute Enrichment: Combine multiple Epicor fields or external data sources to create rich product descriptions and attributes required by Walmart's `Item` entity.
  • AI-Driven Defaulting: AI can infer and default values for non-mandatory fields based on historical data or business rules, speeding up mapping.

🛡️ Error Handling

  • Walmart API rate limit exceeded (iPaaS retries with backoff).
  • Invalid product SKU from Walmart order (iPaaS flags, routes to dead-letter queue, alerts).
  • Epicor API internal server error (iPaaS retries).
  • Missing mandatory product attribute for Walmart `Item` creation (iPaaS alerts, prevents sync).
  • Network connectivity issues between iPaaS and either system (iPaaS retries, alerts on prolonged failure).

Frequently Asked Questions

Common questions about integration implementation, security, and best practices.

AI & iPaaS FAQs

▸ How does AI specifically help with Epicor and Walmart Marketplace integration?
AI significantly accelerates and enhances integration by suggesting optimal field mappings, auto-generating workflow steps, detecting anomalies in data flows (e.g., potential fraud in orders), and even recommending solutions for common errors. This reduces manual effort, improves data quality, and provides predictive insights.

Low-Code/No-Code FAQs

▸ Can I use low-code tools to customize complex Epicor-Walmart workflows?
Absolutely. Our iPaaS provides extensive low-code/no-code capabilities, allowing business analysts and citizen integrators to visually design, configure, and customize complex workflows using drag-and-drop tools. You can add conditional logic, integrate with other systems, and define custom data transformations without writing extensive code.

Data Synchronization FAQs

▸ How do you ensure real-time inventory synchronization between Epicor and Walmart?
We achieve near real-time inventory sync by configuring Epicor's BPM engine to trigger an event whenever inventory changes (`Part` entity). Our iPaaS then immediately retrieves this update, transforms it, and pushes it to Walmart's Inventory API, preventing oversells and ensuring accurate stock levels.

Security & Compliance FAQs

▸ What are the security considerations for integrating Epicor with Walmart Marketplace?
Key security considerations include using OAuth 2.0 for API authentication, encrypting all data in transit with HTTPS/TLS 1.2+, implementing least-privilege access for integration users, and securely managing API keys/credentials in a vault. Our platform ensures data at rest encryption, comprehensive audit trails, and compliance with data privacy regulations like GDPR and CCPA.

Error Handling FAQs

▸ How do you handle data discrepancies or errors during Epicor-Walmart integrations?
Our robust iPaaS provides advanced error handling, including automated retries with exponential backoff for transient issues, dead-letter queues for failed messages, and configurable alerts for critical errors. An intuitive dashboard allows monitoring and manual reprocessing of failed transactions, often with AI-assisted diagnostics to speed up resolution.

Epicor Specific FAQs

▸ Can this integration support multi-plant inventory from Epicor to Walmart?
