Chewy EDI 856 FAQ

Common questions about 856 Ship Notice/Manifest transactions with Chewy.

How long does it take to set up Chewy EDI with Stacksync?

Most suppliers are fully connected and processing live Chewy EDI transactions within 3–5 business days. Stacksync's no-code setup means you don't need developers or EDI consultants — configure your field mappings through our visual interface, run a test cycle, and go live.

Do I need an existing VAN or AS2 connection to trade with Chewy?

No. Stacksync handles the entire EDI transport layer. We connect directly to Chewy's trading partner network through our certified connections. You don't need to manage a separate VAN subscription, AS2 certificates, or SFTP configurations.

How does Stacksync help with Chewy compliance?

Stacksync improves compliance scores by eliminating manual processing delays. Purchase Orders sync to your system in real time, ASNs are generated automatically when you ship, and invoices are validated with three-way matching before submission. Real-time monitoring alerts you to issues before they become chargebacks.

What EDI document types does Stacksync support for Chewy?

Stacksync supports all EDI document types required by Chewy — including Purchase Orders (850), Invoices (810), ASNs (856), PO Acknowledgments (855), and more. Our platform handles the full lifecycle from order to payment automatically.

Can I connect Chewy EDI to my existing ERP or WMS?

Yes. Stacksync integrates with any system that has a database or API — including SAP, Oracle, NetSuite, Microsoft Dynamics, and custom-built ERPs. Data flows bidirectionally between Chewy's EDI network and your system in real time.

What happens when Chewy updates their EDI specifications?

Stacksync monitors Chewy's EDI spec changes and updates our mappings proactively. When a change affects your integration, we notify you and apply updates — so you stay compliant without scrambling to decode new implementation guides.
