Sell on Amazon

Ship the Amazon orders you fulfil yourself from China, under your own name. They come to us through your Shopify store; we buy, check and pack each one in your box, and the tracking goes back to Amazon.

Connect Amazon

  1. Install NinjaBuy in your Shopify store

    The app registers a shipping location named Fulfilled by NinjaBuy and links your store to your NinjaBuy account. The full walk-through is in the Shopify guide.

  2. Map each product you sell to its listing in China

    Import new products with the importer, or map a variant you already sell to a Taobao, Weidian or 1688 listing in the app.

  3. Add Shopify Marketplace Connect and sign in with your Amazon seller account

    Amazon decides which categories and brands your account may sell. Approvals happen on Amazon's side.

  4. Match each Amazon offer to a NinjaBuy product

    Create new offers from your Shopify products, or link offers you already have, in Marketplace Connect. Every product behind them must be mapped to a listing in China or to stock on your shelf.

  5. Set handling and transit times for China

    Amazon shows buyers a delivery date from your shipping settings. Make sure it is one you can meet.

  6. Sell

    Seller-fulfilled orders reach us by themselves, and the shipment is confirmed on Amazon with its tracking.

On Amazon, you are the seller of record

Amazon allows dropshipping when you are the seller on every order. Read its policy in Seller Central before you list: Amazon's drop shipping policy. In short:

  • Your name on everything
    You are named as the seller on packing slips, invoices and the outside of the box. Your branded box and insert do that; see Packaging and QC.
    Amazon's drop shipping policy
  • No one else's paperwork
    Slips or invoices naming another seller come out before it ships. We repack every item, so the Chinese seller's papers stay with us.
    Amazon's drop shipping policy
  • Not bought retail and shipped direct
    Buying from another online retailer and having it shipped to your buyer is not allowed. Wholesale sources (1688), or stock you hold with us, are the safer routes.
    Amazon's drop shipping policy
  • Returns are yours
    You accept and handle returns. Decide where they go and what you refund before you list; see returns.

TrackingNinjaBuy → Shopify → AmazonWe add the tracking number to the Shopify fulfillment; Marketplace Connect passes it on.
StockNinjaBuy → Shopify → AmazonA sold-out source sets the Shopify quantity to 0, by your sync rules; Marketplace Connect updates the listing.

New productsNinjaBuy → Shopify → AmazonThe importer pushes a draft to Shopify; you publish it to Amazon from Marketplace Connect.

Amazon's fees and your margin

Amazon takes a referral fee that depends on the category, and may charge other selling fees. Put your rate into the importer's marketplace fee estimate so the margin reflects it. Our own fees are in Fees.

Troubleshooting

What you seeWhyWhat to do
An Amazon order is missing from ShopifyOnly seller-fulfilled orders come over, and Marketplace Connect brings them in.Check that the offer is fulfilled by you, then check the order in Marketplace Connect.
Shopify shows the fulfillment request as rejectedA line on the order is not mapped to a NinjaBuy listing. The rejection names the lines.Map those variants in the app, then request fulfillment again from the Shopify order.
The order never reached NinjaBuyThe product ships from another location, so Shopify sent the order there instead.In Shopify, set the product to ship from Fulfilled by NinjaBuy. Orders placed before the change stay where they were sent.
The order shows as heldYour balance could not cover it. We never buy on credit.Top up; held orders go ahead on their own. See held orders.
No tracking on the order yetTracking goes back only once the parcel has left our warehouse.Check the order's step in your NinjaBuy account. Once it shows Shipped, the number is on the Shopify fulfillment.
A cancellation was refusedWe grant a cancellation until the order is packed into a parcel. After that, it is already on its way out.Ask us from the order's conversation; a return is still possible in some cases. See cancellations.
The app stopped answering after an uninstallUninstalling drops the app's access to your store. The link to your NinjaBuy account is kept.Install it again and open it once. Your mappings and account link are still there.
