The Challenge

The Disconnect: Why Manual Processes Between BigCommerce & Epicor E9 Hold You Back

Without a seamless connection, your BigCommerce storefront operates in isolation from your Epicor E9 ERP, leading to a cascade of operational inefficiencies, missed opportunities, and financial discrepancies. This disconnect creates a significant drag on growth for modern businesses.

  • Manual order entry from BigCommerce into Epicor E9 is slow, error-prone, and resource-intensive.
  • Delayed or inaccurate inventory updates from Epicor E9 to BigCommerce lead to oversells, backorders, and customer dissatisfaction.
  • Disjointed customer data across systems hinders personalized marketing and customer service efforts.
  • Reconciling BigCommerce payment transactions in Epicor E9 is a time-consuming, daily accounting challenge.
  • Inconsistent product information across channels due to manual catalog management.
  • Lack of real-time visibility into sales, inventory, and fulfillment performance.

Technical Integration Details: Connecting BigCommerce and Epicor E9

Our iPaaS provides a robust, API-first approach to integrate BigCommerce and Epicor E9. This ensures secure, scalable, and real-time data exchange, leveraging the strengths of both platforms.

Data Flow Steps

**Secure Connection:** Establish secure API connections to both BigCommerce (using OAuth 2.0 or API Keys) and Epicor E9 (leveraging its REST or SOAP APIs, often via a dedicated Epicor E9 integration layer).

**Event Listener Setup:** Configure BigCommerce webhooks for critical events (e.g., `order/created`, `product/updated`, `customer/created`) to trigger iPaaS workflows.

**Data Extraction:** iPaaS retrieves relevant data from the source system based on the event trigger or scheduled query.

**Transformation & Validation:** Data is mapped and transformed from the source schema to the target schema using the iPaaS's visual mapping canvas and business rules engine. AI assists in suggesting optimal transformations and validates data integrity.

**Error Handling & Retry:** Built-in mechanisms for retrying transient errors (e.g., API rate limits) and logging persistent failures to a dead-letter queue for review.

**Data Delivery:** Transformed data is securely pushed to the target system via its respective API endpoint.

**Status Updates:** Where applicable, status updates (e.g., order fulfillment status, shipment tracking) are pushed back to the originating system.

Mapping Notes

BigCommerce `id` typically maps to a custom field in Epicor E9 `OrderHed` for traceability. BigCommerce `status` requires careful mapping to Epicor E9 `OrderStatus` values. Line item details (SKU, quantity, price, discounts) are crucial for accurate `OrderDtl` creation in Epicor E9.
