(01)What it is
The 943 announces an inbound shipment to a warehouse: stock moving from a factory, a vendor or another warehouse into the 3PL. The warehouse uses it to plan receiving and to check what arrives against what was expected.
It is the inbound counterpart to the 940, and the 3PL answers it with a 944 once the goods are received.
Not every 3PL uses the 943. Some accept advance notice of inbound shipments through their own portal or an API instead, and some only work from the 944 after goods arrive.
(02)What it carries
- 01Shipment reference and expected arrival
- 02Items and quantities being sent
- 03Origin and carrier details
- 04Lot numbers or other tracking the warehouse needs to record
In plain language. Each trading partner’s implementation guide sets the exact fields it requires.
(03)Where it fits
Documents usually exchanged before and after the 943.
(04)In NetSuite
Send the 943 from the NetSuite purchase order or transfer order that brings stock to the 3PL’s location, once it has actually shipped. Keep the reference so the 944 can be matched back to it.
(05)Common mistakes
- 01Sending the 943 when the PO is placed rather than when goods ship, so the warehouse expects stock weeks early.
- 02Leaving out lot or serial details the warehouse needs to receive the goods properly.
