Chewy EDI Integration for Pet Suppliers

Chewy is America's largest online pet retailer — serving over 20 million active customers with more than 110,000 products across pet food, supplies, pharmacy, and more. SBSA Technology handles full EDI compliance for both Chewy fulfillment models: warehouse (1P) and drop ship (3P) to customer.

Your Chewy Fulfillment Model

Select your supplier type to see requirements

1
Receive EDI 850 Purchase Order from Chewy

Chewy sends a replenishment PO for inventory shipped to their fulfillment centers. Review item quantities, ship dates, and destination DC.

2
Acknowledge with EDI 855 within 24 hours

Confirm your ability to fulfill at the line item level — including quantities, pricing, and revised ship dates if needed.

3
Ship complete to Chewy's fulfillment center

Prepare cartons with GS1-128/UCC-128 labels. Ship full orders wherever possible — flag backorders in the 855, never cancel them.

4
Send EDI 856 ASN before freight arrives

The Advance Ship Notice must be transmitted before your shipment reaches the Chewy DC. A missing or late ASN can result in a refused shipment.

5
Invoice via EDI 810 — one per PO

Submit one invoice per purchase order. Match line items and pricing exactly to the confirmed 855 acknowledgment.

1
Receive EDI 850 with customer ship-to address

Drop ship POs include the end customer's name and delivery address. Ship directly from your facility to the customer.

2
Acknowledge with EDI 855 within 24 hours

Same acknowledgment rules apply — confirm fulfillment at the line item level within the required window.

3
Generate Chewy-branded packing slip

Your company name must not appear on the shipment. Chewy's branded packing slip is generated from ASN data and must accompany every drop ship order.

4
Send EDI 856 ASN as order ships

Transmit the ASN immediately when the order leaves your facility. Chewy uses this to notify the customer with a tracking number.

5
Invoice via EDI 810 per shipment

One invoice per fulfilled drop ship order. Match to the confirmed 855 exactly — Chewy reconciles against this at payment.

Two Ways to Supply Chewy

Chewy operates two distinct supplier models with different EDI specifications and operational requirements. SBSA Technology supports both models simultaneously — with destination-aware automation for each.

First-Party Warehouse Supplier

You ship inventory to a Chewy fulfillment center. Chewy owns the sale, sets the price, and ships to the end customer. This is the standard wholesale model for established brands with volume commitments.

Warehouse / 1P

Third-Party Drop Ship Supplier

Chewy sells the product on their site and routes the order to you. You ship directly to the end customer using a Chewy-branded packing slip. Ideal for long-tail SKUs, oversized items, and specialty products.

Drop Ship / 3P
20M+ Active Chewy customers purchasing pet products
110K+ Products across food, supplies & pharmacy
24 hrs 855 PO acknowledgment window — required
100% ASN compliance required before freight arrival

Three Ways to Connect with Chewy

Chewy supports AS2, SFTP, and VAN for EDI transmission. SBSA Technology handles complete setup, testing, and ongoing compliance monitoring for all three protocols.

SFTP

Secure File Transfer

Secure FTP-based document exchange — a practical choice for suppliers with existing SFTP infrastructure or those stepping up from manual order processing to full EDI automation.

  • Protocol: SFTP (SSH File Transfer Protocol)
  • Standard: ANSI X12 flat files
  • Best for: Mid-volume suppliers with SFTP experience
  • SBSA manages: SFTP setup, file routing & monitoring

EDI VAN

Managed Network

Value-Added Network transmission for suppliers who prefer a fully managed, intermediary-based connection. SBSA acts as your complete EDI department — routing, translating, and monitoring all Chewy documents through the VAN.

  • Protocol: EDI VAN — SBSA provides EDI ID
  • Best for: Smaller or new-to-EDI suppliers
  • Monitoring: 24/7 document tracking and alerts
  • SBSA manages: Full VAN setup, routing & compliance

Chewy EDI Integration EDI Transaction Set

SBSA Technology supports core and supplemental Chewy EDI Integration EDI documents. Critical transactions are highlighted because they carry the highest compliance risk when transmitted incorrectly or late.

850

Purchase Order

Chewy's PO initiates the fulfillment cycle. Specifies ship-to location (Chewy DC or customer address for drop ship), item numbers, quantities, requested ship dates, and pricing.

Inbound
855

PO Acknowledgment

Must be sent within 24 hours of PO receipt. Confirms ability to fulfill at line-item level — quantities, pricing, ship dates. Used to flag backorders with revised dates, not cancel lines.

Outbound 24-hour acknowledgment deadline
856

Advance Ship Notice

Transmitted as the shipment leaves your facility — before freight arrives. Drop ship ASNs trigger Chewy's customer notification with tracking. Missing ASN can result in refused shipment.

Outbound Must transmit before physical arrival — refusal risk
810

Invoice

One invoice per PO or shipment. Must match confirmed 855 quantities and pricing exactly. Discrepancies between invoice and acknowledgment trigger payment holds.

Outbound Must match confirmed 855 exactly
997

Functional Acknowledgment

Confirms syntactic validity of every transmitted EDI document. SBSA monitors all 997 responses and surfaces rejections before they escalate into compliance issues.

Outbound
820

Payment Remittance

Chewy's payment order and remittance advice — automatically reconciled against open invoices when received, eliminating manual cash application work.

Inbound
860

PO Change Request

Buyer-initiated PO modifications from Chewy's purchasing team. Quantity, pricing, or delivery changes are applied at line-item level and flagged in your ERP automatically.

Inbound
753

Routing Request

Used in some drop ship configurations to request carrier routing instructions before shipment — particularly for large or specialty items requiring specific carrier handling.

Inbound

Connects with Your Existing Systems

SBSA Technology integrates Chewy EDI directly with your ERP or order management platform — so Chewy POs flow automatically into your system and ASNs are generated on shipment without manual data entry.

NetSuite

Native SuiteApp integration — Chewy POs create sales orders automatically, ASNs trigger on item fulfillment, and invoices are generated from NetSuite billing records.

SAP (S/4HANA & ECC)

Direct IDOC and RFC-based integration with SAP SD and MM modules. Full Chewy compliance mapping to SAP document types with automated workflow triggers.

QuickBooks Online

Chewy POs mapped to QuickBooks Online purchase orders and sales receipts. ASNs and invoices generated and synced automatically — eliminating double-entry for small and mid-size pet suppliers.

QuickBooks Enterprise

Full EDI-to-QuickBooks Enterprise integration including inventory sync, advanced inventory management, and multi-location fulfillment support for larger pet product operations.

Shopify / Shopify Plus

Chewy drop ship orders routed directly into Shopify as orders — fulfillment triggers the ASN automatically, and tracking numbers flow back to Chewy's customer notification system.

Microsoft Dynamics 365

Chewy EDI FAQ

Common questions from pet product suppliers beginning their Chewy EDI compliance journey.

Chewy operates two supplier programs: (1) Warehouse / First-Party (1P) — you ship inventory to a Chewy fulfillment center and Chewy sells it to customers; and (2) Drop Ship / Third-Party (3P) — Chewy sells on their site and routes orders to you for direct shipment to the end customer. Each model has different EDI 850 specifications. Drop ship POs include the customer's name and delivery address, and require a Chewy-branded packing slip. SBSA handles both models with destination-aware EDI automation.

Chewy requires the Purchase Order Acknowledgment (EDI 855) to be sent within 24 hours of PO receipt. Missing this window negatively affects your on-time acknowledgment rate on Chewy's vendor scorecard, which tracks your overall compliance performance. SBSA fires the 855 automatically within minutes of receiving a Chewy PO — so you'll never miss the window regardless of time of day or day of week.

Chewy enforces strict ASN compliance. Any shipment received at a Chewy fulfillment center without a valid Advance Ship Notice, or with an ASN that arrives after the physical goods, can be refused and returned to you at your cost. A refused shipment is one of the most expensive outcomes in supplier compliance — the goods come back, the PO remains open, and your fill rate takes a hit. SBSA transmits the 856 ASN automatically the moment your shipment leaves your facility, preventing this scenario entirely.

Yes — for all drop ship (3P) orders, the packing slip must carry Chewy's branding only. Your company name, logo, return address, and any supplier branding must not appear anywhere on the package. Chewy owns the end-customer relationship for these orders, and the unboxing experience must match their brand standards. SBSA automatically generates the Chewy-branded packing slip from your ASN data at the time of shipment — no manual document preparation required.

No — Chewy expects backorders to be communicated, not cancelled. If you cannot fulfill an item at the time of shipment, you must reflect this in your EDI 855 PO Acknowledgment by updating the quantity or providing a revised ship date at the line item level. Silently cancelling a line without notification counts against your fill rate metrics. Never enter a quantity of zero on the ASN for an item you can't ship — remove the line entirely instead, as a zero-quantity line is treated as a data error by Chewy's system.

SBSA Technology integrates with a wide range of ERP and order management systems for Chewy EDI — including NetSuite, SAP (S/4HANA and ECC), QuickBooks Online (Intuit Silver Partner), QuickBooks Enterprise (Intuit Silver Partner), Microsoft Dynamics 365, Shopify and Shopify Plus, and major 3PL / WMS platforms like ShipBob and 3PL Central. For custom or legacy systems, SBSA connects via flat file, REST API, or database connector.
