Amazon Vendor Central Integration Explained: Automate PO Orders, ASN, Invoices & More

Retail Procurement vs. Direct Fulfillment—Here’s What Every Vendor Needs to Know

If you’re managing your Amazon business through Vendor Central (VC), you already know how complex the process can be. Whether you’re operating under Retail Procurement or Direct Fulfillment, every PO order, ASN, shipping label, and invoice must follow strict formatting and delivery rules.

As an official Amazon technology partner, Synctify provides a fully automated solution to help vendors manage these operations effortlessly—with API-level integration, EDI format support, and simple onboarding through Amazon’s Appstore.


What is Vendor Central, and What Are Its Two Modes?

Amazon Vendor Central is a 1P (first-party) platform where Amazon purchases goods directly from you or requests that you fulfill orders on its behalf. It consists of two key operational models:

1.  Retail Procurement

  • Amazon places purchase orders (POs), and the vendor ships in bulk
  • You handle PO confirmation, ASN (Advanced Shipping Notice), BOL (Bill of Lading), packing slips, and invoicing
  • Shipping is often pallet-based or full truckload (LTL/FTL)

2. Direct Fulfillment

  • Amazon sells your products but requires you to fulfill each order directly to the end customer
  • Works similarly to FBM, but all data must conform to Vendor Central EDI protocols
  • You must meet Amazon’s strict fulfillment timelines and return handling procedures

Both models demand high compliance, fast processing, and clean data transmission. Manual handling simply isn’t scalable.
