How it works

Buy Products, Ship to us

You source your products, buy them online, then ship them directly to us.


List Products

You then list your products in your Amazon inventory via Seller Central or Inventory Lab

Inventory Sync

Your Amazon inventory will sync with your Prep Ninjas dashboard within a few hours. 

Create an Inbound Shipment

Once your inventory is synced, you can create an Inbound Shipment. This tells us what orders are on their way, where they are coming from, what items you ordered, and how many. You select the ASINs to ensure your inventory is accurately allocated.
