user Permission Setup

Step 1: Setup Seller Central

You’ll need to give us access to ship by granting us Seller Central sub-account access. Amazon’s Seller University user permission video can be found here:

1. In Seller Central, click “Settings” (found at top-right of the screen) then “User Permissions”.
2. Under “Add a New Seller Central User“, add the email “” and click “Send invitation“.
3. We will accept the invitation when we get the invitation email from Amazon. Then we will email you afterwards to let you know to proceed.
4. After we accept the invitation, you will be able to select the level of permission granted. To add user permissions, log back into Seller Central and go to User Permissions (hover over “Settings” then in the drop-down menu click “User Permissions”. Click “Manage Permissions” for Prep Ninjas. Under the Inventory section, change the buttons to “View & Edit” for “Manage FBA Inventory / Shipments”, “Manage Inventory/Add a Product“, and “Upload Inventory” then click “Continue” at the bottom of the page to save.

Step 2: Verification

We will ensure we have access to each account and let you know if we run into any trouble or if all went well. We will then be set and ready to process products and you can start sending products for us to process.

Day to Day:

Once you’ve made an order that is shipping to us, go to Seller Central and create a new shipping plan with preliminary quantities. Simply leave it as an open shipping plan. We will work through the steps (Prepare Products, Label Products, etc.) and create the shipments after we receive the products. Once the shipping plan is created, complete an Order Notification Form. You can access this from your Client Portal. You’ll be able to see the shipment right away on your Client Portal.

Once we receive your shipment, we will change the status to “Received”. We process shipments in the order we receive them. Once we begin to process your shipment, we will change the status to “In Progress” and once we’ve finished, we will change it to “Shipped – Payment Pending”.

If we run into a problem while processing your shipment, we will change the status to “Hold/Attention Required”. If we require your assistance in resolving the issue, we will send you an email. Once resolved, we will change the status as appropriate.

If you have any problems or questions along the way, please feel free to email us at or use the chat on our site. You can call or text us at +1(541)514-8394 during business hours (9a to 5p US Pacific Time). We also highly recommend you go through the Seller University in your Amazon Seller account if you haven’t already.
