NetSuite + Amazon Vendor Central Integration: 1P purchase orders, straight into your ERP

Vendor Central is Amazon's 1P program: Amazon buys wholesale and issues purchase orders, including Direct Fulfillment orders that ship to the end customer. InfiPlex pulls those POs through the SP-API about every 20 minutes and posts them into NetSuite as sales orders, then reads tracking back out of NetSuite and generates the ASN and invoice documents Amazon requires — no EDI contract needed.

How it works

How this integration works

Vendor Central runs on a purchase-order document flow: Amazon issues an 850, expects an acknowledgment, and requires a compliant 856 ASN and 810 invoice for every shipment, with Direct Fulfillment orders shipping straight to the customer on Amazon's clock. InfiPlex pulls those POs through the SP-API connection about every 20 minutes, which eliminates traditional EDI costs entirely, and posts them into NetSuite as sales orders your team fulfills like any other. Once NetSuite creates the fulfillment and a tracking number exists, InfiPlex reads it back and generates the ASN and invoice to Amazon automatically.
