The Challenge of Retail Giant EDI

OTIF Pressure and Marketplace Competition

OTIF on Every Order

Walmart scores suppliers on delivering on time and in full, and EDI providers report that misses carry fines. Handling purchase orders by hand makes every late or short shipment more likely.

Retail and Marketplace Apart

Many brands sell on Walmart Marketplace and supply Walmart stores at once. When each keeps separate inventory, one unit can end up sold on both.

Stores, DCs, and Drop Ship

Store replenishment, distribution center freight, and Walmart.com drop ship each bring their own documents and timing. Tracking them in separate tools means ship notices and labels slip.

The Solution for Walmart EDI Integration & Order Management

Walmart Measures Every Delivery. Pipe17 Runs the Orders Behind Them.

Walmart documents can move on Pipe17’s managed EDI or your current provider. The strain comes after the document, in homegrown code and a legacy OMS that handle Walmart orders on their own inventory. Pipe17’s Order Operations Platform handles both jobs instead, putting Walmart and DTC orders on one inventory pool.

Automated Walmart EDI Flows

Managed EDI links Pipe17 to your Walmart trading-partner setup, whether a purchase order comes from store and DC replenishment or from the Walmart.com drop ship program. Every document below is tied to a Walmart order Pipe17 is already running.
  • Pull Orders from Walmart. A Walmart purchase order (850), for store and DC replenishment or for a Walmart.com drop ship customer, becomes an order in Pipe17 and goes to the building with inventory to fill it, your own warehouse or a 3PL.
  • Push Order Confirmations to Walmart. Pipe17 answers each purchase order with an acknowledgment (855) drawn from the order itself, confirming the lines you will ship and adjusting any you can fill only in part.
  • Push Fulfillments to Walmart. Once the warehouse confirms a shipment, Pipe17 writes the ship notice (856) from that record, including the SSCC of each labeled case, so it can reach Walmart after confirmation, ahead of the freight.
  • Push Inventory to Walmart. Where a Walmart program asks for inventory advice (846), as Walmart.com drop ship does, Pipe17 reports the units your locations can ship, on the schedule Walmart sets.
  • Push Invoices to Walmart. The invoice (810) follows the ship notice and bills the quantities that actually left your dock on that Walmart order.
  • Acknowledge Every Walmart File. A functional acknowledgment (997) confirms that each document exchanged with Walmart arrived intact.
  • Receive Walmart Application Advice. When Walmart returns an application advice (824) reporting errors in a document you sent, Pipe17 receives it for your team to review and correct.
  • Receive Walmart Text Messages. On Walmart’s Goods for Resale program, text messages (864) Walmart sends its suppliers are received in Pipe17 alongside the rest of your Walmart documents.
  • Log Drop Ship Order Changes. When Walmart.com sends a purchase order change (860) on a drop ship order, Pipe17 records it and returns a 997 confirming receipt, and your team decides how to act on it.
  • Case Label Data on Request. Pipe17’s API serves the GS1-128 (UCC-128) data for each Walmart case to your warehouse or 3PL, and that site prints and applies the labels. Label setup follows your specific Walmart program.
  • Ship From the Right Building. Each Walmart order goes to the location you pick, including a 3PL, which gets a warehouse shipping order (940) from Pipe17 and answers with a shipping advice (945).
  • Post Walmart Orders to Your ERP. Walmart purchase orders post as sales orders to NetSuite, Acumatica, or another ERP, where finance books Walmart revenue with every other channel.
  • Flag Problem Orders. Any Walmart order that Pipe17 cannot route or validate lands in an exception queue for your team.

Walmart EDI Integration FAQs

Pipe17 helps protect a Walmart On-Time In-Full (OTIF) score by routing each purchase order (850) to a location that holds the stock and putting any order it cannot route or validate in front of your team. Walmart still scores delivery against its own OTIF targets. Pipe17's order operations handle routing and exceptions, as the path of an EDI order to your warehouse shows.

As SPS Commerce describes it, Walmart's Supplier Quality Excellence Program (SQEP) tracks ship notices (856) that never arrive, that arrive after the purchase order reaches the receiving DC, or that fail Walmart's data validations, plus, on some shipments, cases missing an SSCC label. Pipe17 writes each advance ship notice (ASN) after the warehouse records which cases left, and your warehouse applies labels from Pipe17's GS1-128 carton label data.

No, Walmart EDI carries the purchase orders Walmart places with you as a supplier, for its stores, DCs, and Walmart.com drop ship, while Walmart Marketplace is where you sell to shoppers as a third-party seller. Pipe17 handles both: marketplace orders arrive through the Walmart Marketplace connector, EDI orders through managed EDI, and both draw on one stock count across the Pipe17 Network.

Yes, Pipe17 receives the application advice (824) Walmart sends to report errors in a document you transmitted, and, on Goods for Resale programs, the text messages (864) Walmart uses to send suppliers notices. Both come in over the same managed EDI connection as your Walmart purchase orders (850), beyond the core X12 documents Pipe17 runs, and your team reviews each error report and corrects the document it names.

Walmart.com drop ship vendors exchange X12 files with Walmart over AS2, SFTP, a VAN, or a solution provider, covering purchase orders (850), acknowledgments (855), ship notices (856), inventory advice (846), order changes (860), and functional acknowledgments (997), per Walmart's drop ship vendor EDI guide. Pipe17 builds each 846 from units you can ship, records each 860 with a 997, and runs the testing managed EDI onboarding includes.

Yes, because Walmart accepts EDI through solution providers, suppliers already exchanging Walmart documents via SPS Commerce or a similar provider can leave that setup as it is. Pipe17 connects to that provider or collects the orders it posts to NetSuite or another ERP, as keeping your Walmart EDI provider next to Pipe17 explains.
