In 2022, US-based sellers alone sold a staggering 4.1 billion products globally through their Amazon marketplace channel (source: With digitalization and ease of execution, sellers have quickly recognized the vital need and significance of this new sales channel and are now emphasizing the need for efficient and effective operations management for profitability and success. It is crucial for Amazon sellers to not only sell their products online and cater to the global market but also to manage and automate their supply chain process and business operations to scale further in the future. Amazon integration with other business applications facilitates the free flow of data between multiple systems, offering a seamless experience. Thus, proper Amazon Seller Central Integration is a must-have for any aspiring marketplace seller as it helps define the overall business strategy for the organization.


The need for efficient application integration is paramount for Amazon sellers working with ERPs such as SAP Business One, QuickBooks, etc. to support various scenarios like Fulfilled by Amazon (FBA), Fulfilled by Merchant (FBM), Vendor Central module, etc. Having understood this aspect, sellers are now eager to adopt cohesive integration methods to streamline their business ecosystem.

The following article will explore the best practices and optimal methods for achieving seamless Amazon Seller Central Integration with ERP systems and allowing merchants to maximize their sales and revenues. Drawing insights from more than 50 mid-sized and enterprise integration projects, this guide will help sellers navigate the Amazon marketplace with key learnings and best practices that businesses need. Join me as I share insights from my personal experiences, address frequently asked questions and get you to think about the not-so-obvious aspects of Amazon Seller Central Integration.

Initiating Amazon and Applying for Amazon Selling Partner API Developer Access

Compliance with Amazon’s strict guidelines and quality checks is a prerequisite for developing integrations with the platform. While securing this approval may take anywhere between 3-6 months and cause potential anxiety, the true reason why Amazon implements this stringent process is to ascertain the developer’s proficiency in navigating the complexities of calling APIs.

To manage throttling and enhance performance efficiency, Amazon Seller Central APIs are segregated into a series of methods. Some of these responses are asynchronous, necessitating the submission of the “Feed ID”, which is then used in the subsequent API call to retrieve the exact data.


If you do not have an approved Amazon Developer Account or prefer to avoid the extended approval wait, consider exploring readymade Amazon Seller Central integration packages by an approved developer like APPSeCONNECT. This eliminates the need for users to navigate through the learning curve associated with API structures for writing and maintaining custom integrations.

Integration Approaches for Amazon Seller Central

When it comes to Amazon Seller Central integration, two distinct approaches come into play, each with its own advantages and setbacks. Let’s discuss these below.


Amazon Seller Central EDI integration

Employing EDI (Electronic Data Exchange) to Amazon Seller Central with other applications involves the consumption of APIs on the Amazon side and consolidating them into EDI structures. Several financial software solutions are equipped with the capabilities to process EDI files. The following are some EDI standards related to Amazon integrations:

  • 850: Amazon Order
  • 856: Shipping Notification (FBM)
  • 810: Invoices
  • 812: Credit Debit Memo

Leveraging EDI integration for Amazon Seller Central has the following advantages.

  • Batch processing of transactions, meaning less load on in-house application
  • Processing of EDI messages already in-built with most enterprise software
  • Ease and convenience of monitoring, especially if EDI is already being used for other integrations and you have internal resources who monitor the EDI messages.

Limitations of using EDI for Amazon Seller Central Integration

  • The information and data exchange occurs in batches rather than in real-time.
  • Often, a single data issue can lead to the failure in the processing of an entire batch.
  • Converting information and data from Amazon into EDI-compatible formats requires intense manipulation
  • Maintaining this integration amid the changes in Amazon API fields can be a demanding and daunting task.

Amazon Seller Central API Integration

Utilizing Amazon Seller Central API methods enables users to retrieve or push information directly into their ERP system and prevent the loss of any data. However, to get there, users would need to code and implement custom program changes and customize the software. This is necessary due to the stark differences between Amazon’s data model and meta-field definitions and those of the ERP systems.

Leveraging API integration for Amazon Seller Central has the following advantages.

  • Real-time information and data exchange with Amazon
  • Easier and simplified management of new API versions and maintaining solution
  • Elimination of the need for file manipulation
  • Easier error handling by identifying and addressing specific erroneous transactions.

Limitations of using API Integration for Amazon Seller Central

  • Intense strain on the financial applications to process individual or small batches of API packets
  • Requires custom integration components on the ERP side
  • Needs better handling of Amazon API throttling limits.

Why Using iPaaS for Amazon Seller Central Integration is a Smart Move

Having considered the advantages and drawbacks of the two abovementioned approaches, it is now time to explore a method that allows for API-based integrations without burdening or extensively customizing the ERP application. This is where leveraging an Integration Platform as a Service (iPaaS) comes into play to handle all the bulk transactions.

By correctly utilizing the APIs on the Amazon side and standard ERP integration methods, an iPaaS significantly reduces the extent of ERP customization required for streamlined integration. This approach introduces elasticity and sophistication to the integration process and helps in efficiently managing large volumes of information without exceeding the Amazon API limits. Simultaneously, it also manages and processes information in batches, avoiding overloading the ERP application. Furthermore, iPaaS solutions also streamline error monitoring efforts and substantially reduce maintenance requirements.

Key Integration Aspects of Amazon Seller Central Integration that Impact Profitability

I would like to share recent interactions I had with customers and prospects that underscore the significance of Amazon Integration.

Let me begin with a leading confectionery brand in Europe. Their North American division decided to sell on Amazon using the FBA model. However, after a few months, they encountered difficulties in reconciling inventory and finance. Unable to track their bottom line effectively, they were forced to suspend their sales on Amazon.

Now, let’s talk about another company in the nutrition and supplements industry. Uncertain about their ability to sell on Amazon successfully without access to key information within the back-end systems, this company was contemplating outsourcing the entire operation to a third party.

These examples emphasize and highlight the critical importance of Amazon Seller Central Integrations for businesses. It enables seamless inventory management, financial reconciliation, and overall operational efficiency, ensuring sustainable and perpetual success on the platform.

Across the integration I have been involved in, these 3 key aspects are the most crucial ones:

Stock Reconciliation

Both FBA and FBM scenarios have their own applicability, driven by varied reasons. In the FBM model, inventory shortages in Amazon Seller Central can lead to potential sales losses, even if the items or products are in stock. Conversely, displaying more stock than the actual numbers can put businesses in a predicament where they cannot fulfill an Amazon order, resulting in a negative impact on the Amazon rating.

Under the FBA model, however, the objective differs – although the Amazon seller is not responsible for fulfilling orders, reconciling shipped stock with what Amazon has received is essential. Failing to do so can have a severely negative impact on any Amazon business and its profitability, as any error or discrepancies can erode the profits.

Shipping Updates

For merchants operating under the FBM model, the responsibility of shipping products directly to the customer is expected. Timely shipping is crucial, ideally on the same day as the order is placed. Once this package has been sent, tracking information is promptly updated on the Amazon account. Delays in shipping and handling not only result in lower customer satisfaction but also negatively impact the product rankings in the search results.

Financial Reconciliation

To accurately assess the net earnings from Amazon, it is crucial for businesses to monitor their bottom line after deducting all the fees. Efficiently managing this process across hundreds and thousands of orders every two weeks demands a robust mechanism. By integrating Amazon with a back-end ERP solution, organizations can ensure that the amount paid by Amazon aligns with the financial records, providing complete and clear visibility. This visibility serves as a foundation for strategic decision-making regarding pricing and promotions.

Conclusion and Further Read

When starting an integration for Amazon Seller Central, it is often more convenient to choose a platform that already supports integration and is a scalable solution for businesses.
