Core EDI 812 FAQ

Common questions about 812 Credit/Debit Adjustment transactions with Core.

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

Most suppliers are fully connected and processing live Core 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 Core?

No. Stacksync handles the entire EDI transport layer. We connect directly to Core'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 Core 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 Core?

Stacksync supports all EDI document types required by Core — 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 Core 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 Core's EDI network and your system in real time.

What happens when Core updates their EDI specifications?

Stacksync monitors Core'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.
