What is SignalEDI?
Definition
- SignalEDI
- SignalEDI is an EDI and API integration platform that gets suppliers ready for trading-partner mandates. This EDI resource explains EDI 856 (Advance Ship Notice), explained for SMB teams for SMB teams evaluating validation, partner readiness, pricing, and operational visibility.
What the 856 is
An 856 is a shipment notice that connects PO, carton, item, carrier, and timing details.
- Shipment ID
- Pack hierarchy
- Carrier/tracking
- Item quantities
Warehouse checks before sending the ship notice
For shipment SHIP8842 against PO1001, reconcile the actual packed quantity of SKU-100 with fulfillment records. A partial shipment must describe what actually ships; do not copy the ordered quantity automatically. The abbreviated segments here demonstrate a header only, not a complete hierarchy or certified ASN.
- Use the partner's required hierarchy, item identifiers and carton or pallet label rules.
- Check shipment ID, ship date and purchase-order references against warehouse records.
- Confirm the required send window from the current partner guide; no universal deadline or chargeback amount is implied.
- Resolve missing packing facts with warehouse ownership before partner testing or approved Production delivery.

Common questions
Retailers use the ASN to plan receiving, verify cartons, and reduce dock exceptions.
Yes. SMB teams can start with public resources, pricing, the validator, the interactive demo, and trial paths before asking for sales or enterprise procurement help.
No. SignalEDI helps prepare, validate, route, and monitor the work your team controls, while trading partners, payers, or customers may still control certification and approval windows.
