The Challenge

The Challenge of Disconnected Marketplace Commerce

Managing your Amazon Seller Central operations manually while running your core business on Epicor P21 leads to significant inefficiencies, costly errors, and missed opportunities. Without a robust integration, data silos prevent a unified view of your inventory, sales, and finances.

  • Manual order entry from Amazon into Epicor P21 is time-consuming and error-prone.
  • Delayed or inaccurate inventory updates lead to overselling on Amazon or missed sales opportunities.
  • Reconciling complex Amazon settlement reports with Epicor P21's General Ledger is a labor-intensive accounting nightmare.
  • Inconsistent product data across systems hinders accurate listings and customer experience.
  • Lack of real-time shipment updates impacts customer satisfaction and Amazon seller performance metrics.
  • Difficulty scaling operations during peak seasons due to manual bottlenecks.

Epicor P21 & Amazon Seller Central Integration: The Technical Deep Dive

Our integration solution leverages an advanced iPaaS platform to orchestrate complex data flows between Epicor P21 and Amazon Seller Central. Built on an API-first, event-driven architecture, it ensures secure, scalable, and real-time synchronization of critical business data.

Data Flow Steps

Connection Setup: Securely establish API connections to both Epicor P21 (via REST APIs, potentially SOAP for legacy modules) and Amazon Selling Partner API (SP-API) using OAuth 2.0.

Data Modeling & Harmonization: Define a canonical data model within the iPaaS. Map and transform disparate data structures from P21 entities (e.g., `Sales Order`, `Inventory Item`) to Amazon's specific `Order`, `InventoryItem`, and `Product` schemas.

Workflow Orchestration: Design multi-step, conditional workflows using a low-code visual builder. For example, 'Amazon Order Received' → 'Validate Data' → 'Create P21 Sales Order' → 'Update Inventory' → 'Notify Amazon of Shipment'.

Event & Trigger Configuration: Set up Amazon SP-API webhooks for real-time order and shipment updates. Configure P21 event listeners or scheduled queries for inventory changes and product master data updates.

Error Handling & Monitoring: Implement robust error detection, automatic retries with exponential backoff, dead-letter queues, and real-time alerts. Centralized dashboards provide end-to-end visibility into integration health.

Deployment & Governance: Promote integration flows through Dev, QA, and Production environments with version control. Ensure compliance with security standards and API rate limits for both systems.

Data Mapping

Key Data Entities & Intelligent Mapping for Seamless Integration

Our iPaaS provides a visual canvas for mapping and transforming data between Epicor P21 and Amazon Seller Central entities. AI-assisted mapping accelerates this process, suggests transformations, and identifies potential conflicts, ensuring data integrity and consistency.

Customer

Synchronizing customer information is crucial for sales and support. Amazon provides limited PII; focus is on order-related buyer info.

Epicor P21 Fields

CustomerID Name Address1 City State Zip Phone Email TermsCode CreditLimit

& Amazon Seller Central | Sync Orders & Inventory Fields

BuyerName BuyerEmail (anonymized) ShippingAddress

Mapping Notes

Epicor P21 `Customer` is the master. Amazon `BuyerInfo` is used to create or match a limited `Customer` record in P21 for order processing, but full P21 `Customer` profiles are not pushed to Amazon due to PII restrictions. Focus on `ShippingAddress` mapping for fulfillment.

Integration Use Cases

Explore how the integration behaves in real business scenarios, with clearly defined steps, outcomes, and execution patterns.

E-commerce Order-to-Cash Automation

A customer places an order on Amazon Seller Central. The integration instantly captures the order, validates it, and creates a corresponding Sales Order in Epicor P21. Once fulfilled in P21 (or WMS), shipment details including tracking numbers are pushed back to Amazon, updating the customer and Amazon's systems.

Integration Steps:

  1. 0 Amazon customer places an order.
  2. 1 Amazon SP-API webhook triggers iPaaS workflow.
  3. 2 iPaaS retrieves `Order` and `OrderItem` details.
  4. 3 Data is mapped and transformed to Epicor P21 `Sales Order` schema.
  5. 4 New `Sales Order` is created in Epicor P21, allocating `Inventory Item`.
  6. 5 P21 system processes fulfillment and generates `Shipment`.
  7. 6 iPaaS captures P21 `Shipment` event.
  8. 7 Tracking details are pushed to Amazon Seller Central's `Shipment` entity.
  9. 8 Amazon notifies customer of shipment.

Business Outcome

Accelerated order fulfillment, reduced manual order entry errors, real-time customer communication, improved Amazon seller performance metrics.

⚡ Transformation Logic

  • SKU Mapping: `OrderItem.SellerSKU` (Amazon) to `OrderLines.PartNum` (P21).
  • Price Calculations: Summing Amazon `ItemPrice`, `ShippingPrice`, `PromotionDiscount` to derive P21 `OrderTotal` and `LineTotal`.
  • Address Harmonization: Parsing Amazon `ShippingAddress` into discrete P21 `Address1`, `City`, `State`, `Zip` fields.
  • Carrier Code Conversion: Mapping P21 `CarrierID` (e.g., 'UPSG') to Amazon's `CarrierCode` (e.g., 'UPS').
  • GL Account Mapping: Assigning Amazon `TransactionType` and `AmountType` to specific P21 `GLAccountID`s for settlement reports.

🛡️ Error Handling

  • Amazon SP-API rate limit exceeded during peak orders.
  • Epicor P21 API unavailable during maintenance.
  • Invalid `PartNum` in P21 for an Amazon `SellerSKU`.
  • Missing mandatory product attribute for Amazon listing.
  • Network connectivity issues between iPaaS and either system.
  • Data type mismatch during transformation (e.g., string to integer conversion failure).

General FAQs

▸ What is the primary benefit of integrating Epicor P21 with Amazon Seller Central?
The primary benefit is achieving seamless, real-time data synchronization and automated workflows across your entire enterprise ecosystem. This eliminates data silos, reduces manual effort, prevents overselling, and ensures accurate financial reporting, leading to increased operational efficiency and scalable growth on Amazon.

Financial FAQs

▸ How does the integration handle Amazon's complex settlement reports for P21 accounting?
Our iPaaS automates the download and parsing of Amazon settlement reports. It extracts individual transaction types (sales, fees, refunds, adjustments), maps them to appropriate general ledger accounts in Epicor P21, and posts them as automated journal entries. AI assistance helps categorize complex fee types, and any unmatched items are flagged for review, significantly streamlining financial reconciliation.

Inventory FAQs

▸ Can I synchronize inventory levels between Epicor P21 and Amazon in real-time?
Yes, absolutely. The integration facilitates real-time, bi-directional inventory synchronization. Changes in Epicor P21 (e.g., new stock, sales from other channels) instantly update Amazon Seller Central. Conversely, Amazon sales trigger updates back to P21, preventing overselling and ensuring accurate stock visibility across all your sales channels.

Security FAQs

▸ What security measures are in place for this integration?
We prioritize enterprise-grade security. This includes OAuth 2.0 for secure authentication to both P21 and Amazon SP-API, TLS 1.2+ encryption for all data in transit, data at rest encryption, secure secrets management for credentials, granular role-based access control, and comprehensive audit trails. We also ensure compliance with data privacy regulations like GDPR and CCPA, especially concerning Amazon's limited customer PII.

Customization FAQs

▸ Does the solution support custom fields in Epicor P21 or Amazon Seller Central?
Yes, our iPaaS is designed for flexibility. It fully supports mapping and synchronizing custom fields (e.g., Epicor P21 'UD fields' or specific attributes in Amazon product feeds). You can easily configure these custom field mappings using our low-code visual interface, ensuring all relevant business data flows seamlessly.

AI FAQs

▸ How does AI enhance the Epicor P21 and Amazon integration?
AI significantly augments the integration by providing capabilities like AI-assisted data mapping suggestions, automated anomaly detection (e.g., unusual order values, inventory discrepancies), intelligent error resolution suggestions, and even predictive analytics for pricing and inventory planning.
