Managed EDI for Amazon suppliers
Amazon wholesale orders. Your EDI work handled.
Selling wholesale to Amazon means keeping purchase orders, item confirmations, shipment details and invoices connected. Roundhouse handles the EDI data entry, document preparation and transmission for you, using our own systems. Your team approves the business details; we do the EDI processing.
Let’s talk about your EDI
What is Amazon Vendor Central EDI?
Amazon Vendor Central EDI is the exchange of standardized business documents between Amazon and its wholesale vendors. In this first-party relationship, Amazon buys merchandise from your business for resale. Purchase orders, acknowledgments, shipment notices and invoices carry the information needed to move those wholesale orders through fulfillment and billing.
We process the orders, not just connect the software.
Roundhouse receives and translates your Amazon purchase orders, prepares responses from your approved availability information, enters shipment data and creates the documents your account needs. You do not need to buy or learn an EDI platform. We support your sales, operations and warehouse teams with the daily processing behind your Amazon business.
- Review readable purchase orders and download PDF copies in our customer portal.
- Confirm what you can supply and provide the actual packing information.
- Approve the documents we prepare for transmission.
- Receive labels that your warehouse can apply to the corresponding cartons.
Amazon EDI documents and carton labels.
These are the core documents and label services we review for an Amazon wholesale account. The current Vendor Central requirements determine the maps, timing and label format for your business. Additional documents depend on the program; this is not a list of universal requirements for every Amazon sales channel.
| Code / format | Document | What we handle |
|---|---|---|
| 850 | Purchase Order | Receive and translate Amazon orders, retaining product identifiers, quantities, destination and date references. |
| 855 | Purchase Order Acknowledgment | Prepare the line-item response from your approved quantities, availability and commercial details. This confirms your fulfillment response, not simply receipt of a file. |
| 856 | Advance Ship Notice (ASN) | Build the notice from the actual shipment, connecting order references, item quantities, carton contents and shipping information. |
| GS1-128 | Carton shipping label | Prepare this barcode label format where specified for your account, with carton identifiers aligned to the ASN. It is not an X12 transaction number. |
| 810 | Invoice | Prepare and transmit approved invoices for shipped goods, checking order references, item identifiers, quantities and billing details. |
| 997 | Functional Acknowledgment | Process technical acknowledgments and follow up on reported EDI errors. A functional acknowledgment does not confirm order acceptance or payment. |
An order response should account for every item.
Amazon needs to know what your business can supply, not just that an order arrived. We prepare the acknowledgment using your approved line-item decisions and quantities. A shortage, unavailable product or changed date needs an appropriate response rather than a blanket acceptance. We review the applicable account rules with your team and keep the response tied to the original order.
The ASN should describe the shipment leaving your warehouse.
Bulk orders can contain many cartons and multiple products. We use the final packing information to connect each shipment to its purchase orders and contents. Carton identifiers on the labels must agree with the shipment data. If packing changes, we update the information before final approval rather than assuming the quantities originally ordered are the quantities being shipped.
- Keep product identifiers and units of measure consistent.
- Use actual packed quantities and carton contents.
- Match the ship-to reference to the order being fulfilled.
- Coordinate shipment notice preparation with your dispatch information.
Keep acknowledgment and invoice details consistent.
The commercial details confirmed on an order need to carry through to billing. We check the approved unit costs, product identifiers, quantities and order references when preparing the invoice for shipped goods. Your team resolves any commercial differences; Roundhouse handles the EDI formatting and transmission. This helps prevent avoidable document discrepancies from becoming billing problems.
Wholesale procurement has its own requirements.
This service focuses on vendors fulfilling wholesale purchase orders from Amazon. Seller Central marketplace sales and Direct Fulfillment orders have different workflows. We establish the documents for your wholesale account instead of applying an inventory-feed or consumer-shipping checklist from another program.
Setup, testing and ongoing processing.
We review your Amazon vendor account requirements, product identifiers, shipment information and approval process, then coordinate document setup and testing. Once processing begins, we handle the recurring EDI work and help address reported document errors. Roundhouse has been helping companies stay EDI compliant for over 20 years.
Reduce EDI errors while your warehouse keeps shipping.
Accurate order responses, consistent carton information and checked invoices help reduce EDI-related chargebacks. Our team handles the documents; your warehouse remains responsible for physical packing, applying the correct labels and meeting shipping arrangements. We coordinate the information between those activities.
Moving your Amazon EDI to Roundhouse.
We plan the handover around open purchase orders, acknowledgments already sent, upcoming shipments and unpaid invoices. Agreeing which provider will handle each outstanding document helps avoid duplicate responses or missed transmissions. Your team gets a clear process for approvals and packing information from the start.
Frequently asked questions
Amazon EDI support
What does EDI stand for?
EDI stands for Electronic Data Interchange. It allows businesses to exchange standardized electronic documents. For Amazon wholesale vendors, those documents connect purchase orders, order responses, shipments and invoicing.
What is EDI 850 and 855?
An EDI 850 is the purchase order sent by the buyer. An EDI 855 is the vendor’s purchase order acknowledgment, reporting the fulfillment response for the ordered items. Roundhouse translates the order and prepares the acknowledgment from your approved information.
Do you do the Amazon EDI work for us?
Yes. We handle EDI data entry, document preparation and transmission using our own systems. Your team provides fulfillment information and approvals without needing to buy or learn EDI software.
Is this service for Amazon wholesale vendors?
Yes. This page covers first-party vendors selling merchandise to Amazon and fulfilling its wholesale purchase orders. That is different from selling directly to consumers through Seller Central.
Do you prepare Amazon ASNs and carton labels?
Yes. We prepare shipment notices and the applicable carton labels from your actual packing details, keeping the carton identifiers and ASN information aligned with your account requirements.
Is an EDI 997 the same as accepting an Amazon order?
No. A 997 is a technical acknowledgment of an EDI transaction. Your business response to the purchase order is a separate step, typically carried by the 855 in the X12 order workflow.
Can you help reduce Amazon EDI-related chargebacks?
Yes. We help reduce EDI-related chargebacks by checking order responses, shipment information, labels and invoices, and addressing reported EDI errors.
Can we view Amazon purchase orders online?
Yes. You can view your purchase orders and download them as PDF files in our customer portal.
