Discover how Vendor Central EDI works, what documents Amazon requires. Learn how Orderful helps vendors integrate seamlessly with Amazon's vendor portal.
Becoming an Amazon Vendor Central supplier is a major milestone. It gives companies access to one of the world’s largest retail channels, but it also comes with strict operational expectations. Amazon moves at a high volume and relies on automated accuracy, so even small mistakes can trigger delays, cancellations, or costly chargebacks.
Many new vendors try to manage orders, shipments, and invoices manually. That usually works for a short time, but as purchase orders increase, manual entry becomes slow, error-prone, and difficult to scale. This is why Amazon expects vendors to exchange business documents through electronic data interchange (EDI).
For most major vendors, including Amazon, Walmart, and Costco, the ability to transmit using EDI is a requirement for suppliers and vendors. And a modern integration approach helps Amazon sellers stay compliant, avoid penalties, and grow without adding unnecessary overhead.

What Is Amazon Vendor Central EDI?
Working with Amazon as a first-party (1P) vendor means orders, shipments, and invoices must move quickly. To keep everything accurate and at scale, Amazon relies on structured digital communication instead of email or spreadsheets. EDI gives vendors a standardized way to exchange essential business documents digitally.
Vendor Central vs. Seller Central
Vendor Central is Amazon’s 1P wholesale model. Companies sell products directly to Amazon, and Amazon resells those items to consumers. Amazon issues purchase orders, sets the price, and manages the customer relationship.
Seller Central works differently. It's Amazon's third-party (3P) marketplace model. Sellers offer their goods directly to consumers through Amazon’s platform and manage their own listings, pricing, and fulfillment.
Because 1P transactions operate like a traditional wholesale partnership, Amazon depends on EDI or API-based communication to automate high-volume order flows and reduce manual errors that disrupt its supply chain.
Why Amazon Uses EDI
Amazon expects documents to arrive in consistent, standardized EDI formats so it can process orders, shipments, and invoices as quickly as possible. Here's how EDI helps vendors meet those expectations:
EDI capabilities reduce manual data entry that often leads to errors.
An EDI system generates predictable document structures that Amazon can validate automatically.
EDI speeds up acknowledgments, shipping updates, and invoice processing.
A modern EDI platform supports compliance across multiple fulfillment centers and routing facilities.
This level of automation keeps goods moving smoothly and helps Amazon maintain reliable delivery performance.
Required Amazon EDI Documents
Amazon relies on several core EDI documents to manage day-to-day operations. Vendors typically need to support:
Purchase orders (EDI 850): Notify vendors of new order quantities and delivery requirements.
PO acknowledgments (EDI 855): Confirm whether the vendor can fulfill the requested items.
Advance ship notices (EDI 856): Detail shipment contents so Amazon can receive cartons and pallets accurately.
Invoices (EDI 810): Provide billing details and support automated payments.
Inventory updates (EDI 846): Help Amazon understand available stock levels.
Some programs also require routing requests or additional fulfillment documents, depending on the product category and delivery method.
The Cost of Non-Compliance With Amazon's EDI Requirements
Amazon’s Vendor Central portal runs on predictable, automated data. When EDI documents arrive late, contain errors, or don’t match shipment contents, Amazon treats the issue as an operational risk. These mistakes often result in costly chargebacks, delayed payments, or damaged vendor performance scores, all of which can chip away at profit margins.
Common Chargebacks and Charges
Amazon enforces strict rules for timing, accuracy, and labeling. Vendors may encounter chargebacks for issues such as:
PO acknowledgment timing: Late responses to purchase orders may lead to compliance deductions.
ASN accuracy and timeliness: Incorrect or late advance ship notices often trigger penalties, especially when shipment contents don’t match the ASN.
Carton and pallet content accuracy: Mislabeled shipments or a misprinted barcode can disrupt receiving and result in rework charges.
Billing issues: Inaccurate invoices or mismatched totals may cause payment delays or invoice-related penalties.
Fee amounts can vary widely, and the cumulative impact of repeated financial penalties can significantly affect profitability.
How Errors Impact Margins
Operational mistakes can ripple across Amazon’s supply chain. That means a single incorrect document can create downstream effects. For many vendors, the biggest margin pressures come from:
Late or inaccurate ASNs: These create delays at fulfillment centers and often lead to additional processing fees.
Incorrect invoice data: Incorrect line items or totals can hold up payments until discrepancies are resolved.
Labeling issues: Improper carton markings or missing identifiers may lead to receiving delays and added rework charges.
Even small inconsistencies can cut into margins, especially for vendors operating with tight wholesale pricing.
Operational Risks Beyond Chargebacks
Financial penalties are only part of the risk. EDI issues can also cause operational setbacks that affect long-term vendor performance. Companies may face:
Inventory inaccuracies: Incorrect stock updates can cause overselling, understocking, or shipment delays.
Canceled orders: Severe or repeated data issues may cause Amazon to cancel or reroute orders.
Scorecard downgrades: Poor operational performance may affect future purchase order volume or program eligibility.
Risk of losing 1P vendor status: Chronic non-compliance can jeopardize Amazon’s confidence in the selling partner relationship.
Amazon EDI Setup Requirements
Setting up Amazon Vendor Central EDI involves a combination of account access, technical preparation, and system alignment. While the process can seem complex at first, understanding the basic requirements can help you choose the right EDI solution and avoid delays during testing or certification.
Prerequisites for Getting Started
Before beginning an Amazon EDI integration, vendors need a few foundational elements in place:
Active Vendor Central account: Amazon only enables EDI setup for approved 1P vendors.
EDI self-service startup enabled: This gives access to Amazon’s internal testing and configuration tools.
Assigned EDI technical contact: Amazon requires at least one representative who can manage testing and communication.
Access to product data and identifiers: Accurate SKUs and GTINs are vital for correct document exchange.
These prerequisites ensure vendors have the right access and data to begin working with an EDI provider.
Connection Methods
Amazon supports several connection methods so vendors and direct fulfillment vendors can transmit documents securely. The most common options include:
AS2: A widely used protocol that encrypts data during transmission.
Secure file transfer protocol (SFTP): Allows direct encrypted file-based transfers for companies using lightweight or web-based EDI systems.
Value-added networks (VANs): Legacy networks that route EDI messages between trading partners.
Application programming interface (API) connections: Amazon’s Selling Partner API is often used for direct fulfillment, giving vendors a real-time alternative to traditional EDI format exchanges.
Each method has different security, automation, and maintenance requirements, which is why many vendors look for an experienced EDI provider to help manage the setup.
Testing and Certification
Amazon requires vendors to pass a structured testing phase before going live. The process typically involves:
Amazon validation steps: Testing and validation confirm that required fields, identifiers, and segments appear correctly in each transmission.
Test transmission cycles for EDI documents: Amazon verifies that the vendor’s EDI system can send and receive 850, 855, 856, and 810 documents accurately.
Timeline expectations: Most testing cycles are completed in stages, and delays often occur when documents fail validation.
ASN accuracy tests: The 856 document is heavily scrutinized because errors can impact warehouse and financial operations.
Successful testing verifies that a vendor’s backend systems can maintain compliance during normal order volume.
Integrating EDI With Internal Systems
Vendors also need to connect their EDI system to ERP, warehouse, and order management platforms so information flows automatically. This stage often includes:
Connections with business systems: Ensures order data flows cleanly between Amazon and WMS, OMS, and ERP systems.
Mapping requirements: Translates Amazon’s EDI format into data fields your business systems can understand.
Manual processes and spreadsheets produce unnecessary risk. Even small inconsistencies can cause downstream errors or document failures. A modern web EDI solution eliminates the need for manual document management while also supporting seamless integration, reducing implementation time, and helping to maintain ongoing compliance.

Amazon Vendor Central FAQs
What is Amazon Vendor Central EDI?
Amazon Vendor Central EDI is the electronic data interchange system that enables first-party (1P) wholesale vendors to exchange business documents with Amazon automatically. As a Vendor Central supplier, companies sell products directly to Amazon, which then resells them to consumers. Amazon issues purchase orders and manages customer relationships, relying on EDI to process high-volume order flows at scale. Required EDI documents include purchase orders (EDI 850) for new order quantities, PO acknowledgments (EDI 855) confirming fulfillment capability, advance ship notices (EDI 856) detailing shipment contents, invoices (EDI 810) for billing and automated payments, and inventory updates (EDI 846) for stock level visibility. EDI reduces manual data entry errors, creates predictable document structures Amazon validates automatically, speeds up acknowledgments and invoice processing, and supports compliance across multiple fulfillment centers. Without EDI, manual order management becomes slow, error-prone, and impossible to scale.
What's the difference between Amazon Vendor Central and Seller Central?
Vendor Central is Amazon's first-party (1P) wholesale model where companies sell products directly to Amazon as the buyer. Amazon issues purchase orders, sets retail prices, manages customer relationships, and handles fulfillment. Vendor Central operates like a traditional B2B wholesale partnership requiring EDI or API-based communication to automate order flows. Seller Central is Amazon's third-party (3P) marketplace model where businesses sell directly to consumers through Amazon's platform. Sellers maintain their own product listings, set their own prices, manage inventory, and choose fulfillment methods (FBA or FBM). Because 1P Vendor Central transactions involve high-volume wholesale orders between businesses, Amazon depends on structured EDI document exchange to maintain supply chain efficiency. Seller Central primarily uses Amazon's web interface and APIs rather than traditional EDI formats.
What are common Amazon Vendor Central EDI chargebacks?
Amazon enforces strict EDI compliance through various chargebacks that impact vendor profitability. Common penalties include late PO acknowledgment fees when vendors don't respond to purchase orders within required timeframes, ASN accuracy and timeliness chargebacks for incorrect or late advance ship notices especially when shipment contents don't match the ASN, carton and pallet content accuracy fees when mislabeled shipments or incorrect barcodes disrupt receiving and require rework, and billing issue penalties for inaccurate invoices or mismatched totals that delay payments. Beyond direct financial penalties, EDI errors cause operational impacts including inventory inaccuracies from incorrect stock updates leading to overselling or understocking, canceled orders when severe data issues force Amazon to reroute shipments, scorecard downgrades affecting future purchase order volume, and risk of losing 1P vendor status entirely from chronic non-compliance. These cumulative costs significantly affect margins, especially for vendors operating with tight wholesale pricing.
How do I set up Amazon Vendor Central EDI?
Setting up Amazon Vendor Central EDI requires several prerequisites including an active Vendor Central account approved by Amazon for 1P wholesale, EDI self-service startup enabled for access to testing and configuration tools, an assigned EDI technical contact to manage communication with Amazon, and accurate product data including SKUs and GTINs for correct document exchange. Amazon supports multiple connection methods including AS2 (encrypted protocol), SFTP (secure file transfers), VANs (legacy networks), and API connections through Amazon's Selling Partner API for direct fulfillment. Vendors must complete Amazon's structured testing and certification process involving validation steps confirming required fields appear correctly, test transmission cycles for EDI 850, 855, 856, and 810 documents, ASN accuracy tests heavily scrutinized for warehouse impact, and timeline expectations typically completed in stages. Finally, integrate EDI with internal ERP, warehouse, and order management systems to ensure automated data flow and eliminate manual processes that create errors.
What EDI documents does Amazon Vendor Central require?
Amazon Vendor Central requires several core EDI documents for day-to-day wholesale operations. EDI 850 (Purchase Order) notifies vendors of new order quantities, delivery requirements, and fulfillment expectations from Amazon. EDI 855 (PO Acknowledgment) confirms whether the vendor can fulfill requested items, accepts or rejects line items, and provides expected ship dates. EDI 856 (Advance Ship Notice) details shipment contents so Amazon can receive cartons and pallets accurately, including product identifiers, quantities, packaging details, and carrier information. EDI 810 (Invoice) provides billing details supporting automated payments with line-item accuracy matching purchase orders and shipments. EDI 846 (Inventory Update) helps Amazon understand available stock levels for ordering and allocation decisions. Some vendor programs require additional documents like routing requests or category-specific fulfillment documents depending on product type and delivery method. All documents must meet Amazon's strict formatting, timing, and accuracy requirements to avoid chargebacks.
