Before a 3PL can ship your orders, it has to receive your stock — and a truckload of unannounced pallets showing up at a busy warehouse dock is how inventory records start their drift from reality. The EDI 943 Warehouse Stock Transfer Shipment Advice fixes the announcement problem: it tells the warehouse, in structured detail, what you're sending, when it arrives, and how to recognize it.
The inbound half of warehouse EDI
The warehouse document family splits cleanly by direction of goods. Outbound — your customer orders — runs on the 940 shipping order and its 945 confirmation. Inbound — your replenishment of the warehouse itself — runs on the 943 and its receipt confirmation, the 944. The 943 is functionally an ASN pointed at your own supply chain: same advance-notice logic as a retail 856, but the recipient is your warehouse operator and the goods aren't changing hands, only locations.
Structurally, a W06 header identifies the shipment with its numbers and dates; N1 loops name the origin, the receiving warehouse, and the carrier context; W04 detail lines list items and quantities, with lot, date, or pallet detail where the operation tracks it.
Why the announcement matters operationally
A 3PL that knows what's coming can do three things a surprised one can't:
- Schedule the labor and the door. Receiving appointments, staffing, and putaway planning all key off expected inbounds. Unannounced freight waits — and at many warehouses, waiting freight incurs handling charges.
- Receive against expectations. With a 943 in hand, the warehouse checks in your shipment against declared quantities, catching discrepancies at the dock while the trailer is still there — instead of absorbing them silently into your stock records.
- Preserve traceability. Lot and expiration detail transmitted in advance means the warehouse records it at receipt, which food, beverage, and regulated-product suppliers need downstream when a recall or audit asks where a lot went.
Skip the 943 and none of this happens. The warehouse receives blind, keys what it sees, and every mismatch between what you shipped and what they counted becomes an untraceable inventory variance you discover at cycle-count time.
There's a scheduling dividend as well: warehouses that can see a week of planned inbounds level their own labor, and suppliers who transmit clean advices tend to find their freight gets doors and putaway priority when capacity is tight. The document quietly buys you service.
The reconciliation loop
The document earns its keep when the 944 receipt advice comes back. Advice says 24 pallets, receipt says 23: now you have a specific, timestamped discrepancy — attributable to the lane, the carrier, or the count — rather than a vague quarterly shrink number. Suppliers running continuous replenishment into 3PLs treat 943/944 matching as a standing control, the inbound mirror of the outbound 940/945 loop. All four documents together are what let your ERP's picture of remote inventory stay trustworthy, which is the foundation everything in our 3PL solution builds on.
EDISQ generates 943s from transfer orders in your ERP, delivers them in whatever dialect your warehouse speaks, and auto-matches the returning 944s — with the discrepancies, not the clean receipts, surfacing for attention. If your product carries lot control, insist the advice carries it too — traceability that starts at the warehouse door is far cheaper than reconstructing it during a recall.
A word on cost
Transfer advices follow your replenishment rhythm, so their volume is steady and low. On EDISQ's per-document pricing they cost accordingly: nothing until you've used the month's 25 free documents, then from $0.50 each, with the marginal rate easing to $0.10 as total volume grows. No mapping or setup fees, and no charge for the warehouse connection beyond the standard $50/month for an additional live partner — the accounting equivalent of the document: simple, and only there when goods actually move.
FAQ
What does the EDI 943 announce?
Inventory you are sending into a warehouse — from your factory, a port, or another facility. It gives the 3PL advance detail of the inbound shipment so receiving can be planned and reconciled.
How is a 943 different from an 856?
Same idea, different audience. The 856 announces a shipment to a customer; the 943 announces a stock transfer to your own warehouse operator. The goods are not changing owners, just locations.
What confirms a 943?
The 944 Stock Transfer Receipt Advice — the warehouse reports what it actually received and in what condition. Comparing the pair is how transfer shrink and receiving errors get caught.
How does EDISQ price the 943?
As one document: free within your monthly 25, then from $0.50 with rates declining by tier. Connecting the 3PL itself carries no setup or mapping fees.
