Amazon EDI Integration
Amazon runs two separate EDI programs under one account: Vendor Central Wholesale, where Amazon buys inventory outright, and Vendor Central Direct Fulfillment, where Amazon places dropship orders you ship directly to the customer. Different rules, different transaction flows, different backends. We build and maintain both, treated as genuinely separate integrations.
+ RULES
The scope, and what has to get right.
-
WHOLESALEVendor Central Wholesale EDI. Amazon purchases inventory outright through 850 purchase orders. You ship to an Amazon fulfillment center and invoice Amazon directly. -
DIRECT FULFILLMENTVendor Central Direct Fulfillment EDI. Amazon places dropship orders on your system, and you ship directly to the end customer under Amazon's own routing rules. - Same account, different rules. Both programs can run on one Vendor Central account, but with different transaction flows, different routing requirements, and different failure modes.
Inside the system, not bolted on.
Built and maintained as separate flows
Each program's transaction sets, routing rules and edge cases are mapped separately, so a change in one does not risk breaking the other.
753/754 routing for Direct Fulfillment
Routing request and instructions are handled as their own step before the ASN can go, specific to how Amazon routes dropship shipments.
One dashboard, two flows underneath
Staff see a unified order view even though wholesale and dropship orders follow different EDI paths behind it.

Amazon Vendor Central Wholesale EDI
Amazon Vendor Central Wholesale means Amazon buys your inventory outright and resells it. Orders arrive as 850 purchase orders, you acknowledge, ship to an Amazon fulfillment center, send an 856 advance ship notice and an 810 invoice, all mapped directly inside your ERP rather than through a middleware provider.
753 · 754 · 856 · 810Amazon Direct Fulfillment EDI
Amazon Direct Fulfillment means Amazon places dropship orders on your system and you ship directly to the end customer rather than to an Amazon warehouse. It runs on the same Vendor Central account as Wholesale but with its own routing exchange, its own rules, and its own failure modes, which we build as a separate integration.
Multi-marketplace ERP, EDI and logistics automation for a US consumer electronics brand
- Off Sage, with the operating history intact: Customers, vendors, items and transaction history were migrated from Sage into a browser-based ERP covering order-to-cash and procure-to-pay, with a full general ledger, receivables and payables, so the business changed systems without losing its records.
- Native EDI inside the ERP: Direct trading-partner connections for Amazon Vendor Central, Walmart, HSN, QVC and Costco with 850, 855, 856, 810, 846 and 997 documents, polled on schedules as short as ten minutes. Every job is tracked on a monitoring dashboard, and there is no third-party EDI middleware in the chain.
- Every channel in one order queue: Amazon Vendor Central and Seller Central (SP-API), Walmart, HSN, QVC, Costco, several Shopify storefronts, eBay and direct wholesale accounts land in one system. Vendor Central purchase orders are accepted or rejected back to Amazon from the same screen that shows system, 3PL and allocated stock.
- Multi-warehouse and multi-3PL stock: Real-time inventory across an owned warehouse operated with a logistics partner, a second third-party warehouse and Amazon fulfillment locations, with warehouse transfer orders and an Amazon inbound shipment request action for FBA.
- International purchasing and landed cost: Ocean and air freight purchase orders carry ETD, bill of lading, ETA and vessel details, and the ERP calculates landed cost at receiving from tariff classification, duty, tariff, harbor surcharge and freight per item.
Common questions.
Is Vendor Central the same as Seller Central?
No. Vendor Central runs on EDI and Amazon is the buyer of record. Seller Central runs on SP-API and you are the seller of record. They are different relationships with Amazon, not two names for the same thing.
Can we run Wholesale and Direct Fulfillment on the same account?
Yes, and many vendors do. The two programs use different transaction flows and rules, which is exactly why we build them as separate integrations rather than one shared mapping.
Which one should we start with?
Whichever one Amazon has already enrolled you in. If you are being asked to support both, they still get built and tested separately, since the failure modes are different for each.
What happens if a Direct Fulfillment order is routed incorrectly?
The 753/754 routing exchange happens before the ASN goes out, so a routing problem shows up early rather than after the shipment is already in transit.

Not sure which Amazon program you're actually on?
Tell us whether Amazon owns the inventory or you're shipping direct to the customer, and we will tell you which integration you actually need.
