Walmart National PO Program: How NPO Impacts Vendor Costs and Supply Chains

On March 19, Walmart rolled out details on its upcoming National Purchase Order (NPO) program for prepaid transportation vendors.

The big shift: Inbound product flow moves through their new automated ACC network (currently live in Minooka, IL and Lebanon, PA) instead of the traditional 42 RDC's direct. This not only changes delivered transportation costs but significantly reduces fulfillment costs as well.

There’s still a lot that isn’t clear yet, but depending on your network, this could materially change your COGS.

• Every Day Low Price wins.
  

We put together a simple model to help vendors pressure test it:

• Compare NPO (ACC flow) vs your current RDC network

• See impact across storage, handling, and freight

• Align ACC costing to cube adjusted product weight (CAW)

• Compare NPO (ACC flow) vs your current RDC network

• Get to a directional answer quickly
  

Plug in your own numbers and let the pro forma provide the output. It's intentionally simple.
