The Challenge

The Disconnect Between Your ERP and eCommerce Channel

Managing a thriving Amazon Marketplace presence while relying on Epicor E9 as your core accounting and ERP system can quickly become a complex, error-prone, and resource-intensive challenge without robust integration. The lack of real-time data flow creates significant operational bottlenecks and impacts profitability.

  • Manual order entry from Amazon into Epicor E9 is slow, costly, and prone to human error.
  • Out-of-sync inventory leads to overselling on Amazon, customer dissatisfaction, and costly cancellations.
  • Delayed or inaccurate product and pricing updates on Amazon due to manual processes.
  • Complex Amazon Settlement Reports require extensive manual reconciliation, delaying financial closes and increasing audit risk.
  • Lack of real-time visibility into Amazon sales performance within Epicor E9 hinders strategic decision-making.
  • Inefficient handling of customer returns and refunds across both systems creates discrepancies and frustrated customers.

Technical Integration Details: Epicor E9 and Amazon Marketplace

Our iPaaS-driven solution provides a robust and secure framework for connecting Epicor E9 with Amazon Marketplace, leveraging the latest API technologies and best practices to ensure seamless data flow and operational excellence. The architecture is designed for scalability, reliability, and ease of management.

Data Flow Steps

Connect & Authenticate: Establish secure API connections to Epicor E9 (via its REST/SOAP APIs or database connectors) and Amazon SP-API (using OAuth 2.0).

Define Workflows: Visually design integration flows within the iPaaS, specifying triggers (e.g., new Amazon order, Epicor E9 inventory update), actions, and conditional logic.

Map Data Schemas: Utilize the iPaaS's visual mapping canvas to transform data between Epicor E9's internal data structures and Amazon's SP-API schemas (e.g., Order to Sales Order, Inventory to Listing).

Implement Business Rules: Apply custom logic for pricing, quantity buffers, customer matching, tax calculations, and GL account assignments.

Deploy & Monitor: Publish the integration workflows to a production environment, with continuous monitoring, logging, and alerting for all transactions.

Error Handling & Retries: Configure automated retry mechanisms with exponential backoff for transient API errors and dead-letter queues for persistent failures.

Data Touchpoints

Amazon Marketplace: Orders, OrderItems, Products (ASIN/SKU), Inventory/Stock, Shipments, Payment Settlement Reports, Refunds, Customer (limited), Listings, Fees, FBA Shipment Plans, Promotions.
Epicor E9: Sales Orders, Sales Order Lines, Inventory (Part/Warehouse), Products (Part Master), Customers, Accounts Receivable, Accounts Payable, General Ledger, Shipments, Purchase Orders (for FBA inbound).
iPaaS: Canonical Data Models for Orders, Products, Inventory, Financial Transactions.

"The integration architecture typically involves a central iPaaS layer acting as the orchestrator. Data flows from Amazon Marketplace (Orders, Shipments, Settlement Reports) into the iPaaS, where it is transformed and then pushed into Epicor E9 (Sales Orders, Shipments, GL entries). Conversely, data from Epicor E9 (Inventory, Products, Pricing) flows through the iPaaS, is transformed, and then pushed to Amazon Marketplace (Listings updates, FBA Inbound Shipments). All interactions are via APIs, with event-driven patterns for real-time data and scheduled batches for periodic updates."

Frequently Asked Questions

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

General FAQs

▸ Why is integrating Amazon Marketplace with an iPaaS essential for my business?
Integrating Amazon Marketplace with an iPaaS streamlines operations by automating data flow between Amazon and your Epicor E9 ERP, WMS, and accounting systems. It ensures real-time inventory, accurate order processing, faster financial reconciliation, and reduces manual errors, leading to significant cost savings and improved customer satisfaction. It's crucial for scalability and maintaining data integrity across your enterprise.

Technical FAQs

▸ What is the Amazon Selling Partner API (SP-API) and how does it impact integration?
The Amazon Selling Partner API (SP-API) is Amazon's modern, unified API for programmatic access to seller data and functionalities. It's central to any modern integration, allowing real-time interaction for orders, inventory, listings, and fulfillment. An iPaaS leverages SP-API connectors to abstract its complexity, enabling robust, API-first integrations without extensive custom coding.
▸ How does an iPaaS handle Amazon's API rate limits?
An advanced iPaaS includes built-in rate limit management features. It intelligently queues, batches, and throttles API requests to Amazon's SP-API, using strategies like exponential backoff and dynamic delays. This ensures your integrations operate smoothly, preventing errors due to exceeding Amazon's API call quotas.

iPaaS Capabilities FAQs

▸ Can I use low-code/no-code tools to build Epicor E9 and Amazon Marketplace integrations?
Absolutely. Modern iPaaS platforms offer low-code/no-code environments, empowering business users and analysts to design, configure, and manage Epicor E9 and Amazon Marketplace workflows using visual drag-and-drop interfaces. This democratizes integration, accelerates deployment, and reduces reliance on IT developers for routine changes.

Data FAQs

▸ What are the key data entities typically synchronized between Epicor E9 and Amazon?
Key entities include Amazon Orders (mapped to Epicor E9 Sales Orders), OrderItems (to Sales Order Lines), Products (SKUs/ASINs mapped to Epicor E9 Parts), Inventory/Stock Levels (from Epicor E9 to Amazon Listings), Shipments (with tracking info), and Financial Settlement Reports (reconciled in Epicor E9 GL). Customer data, Returns, and FBA Inbound Shipment Plans are also critical.

AI Features FAQs

▸ How can AI enhance my Epicor E9 and Amazon Marketplace integration workflows?
AI can augment workflows by providing intelligent data mapping suggestions, detecting anomalies in order patterns or financial settlements, automating exception handling, predicting inventory needs, and optimizing pricing. This leads to higher data quality, proactive issue resolution, and more strategic decision-making.

Security FAQs

▸ How do I ensure data security and compliance when integrating Epicor E9 and Amazon Marketplace?
Ensure your iPaaS and integrations adhere to Amazon's Data Protection Policy. Use OAuth 2.0 for authentication, implement least-privilege access, encrypt all sensitive data at rest and in transit, and comply with regional data privacy regulations like GDPR or CCPA. Regular security audits of both Epicor E9 and the iPaaS are vital.

Business Value FAQs

▸ What is the ROI of investing in a modern iPaaS for Epicor E9 and Amazon Marketplace integration?
The ROI is significant, stemming from reduced manual effort, fewer operational errors, faster order fulfillment, improved inventory accuracy (preventing overselling/underselling), quicker financial closes, and enhanced customer satisfaction. It also frees up IT resources and provides a scalable foundation for future growth and automation initiatives, directly impacting your bottom line.
