Why AMZ Prep Partners With 3Dsellers

eBay sellers expanding to Amazon, Walmart, and Shopify run into the same problem. Listings can sync across channels automatically, but inventory still has to be received, prepped, stored, and shipped. When stock is split between a garage, Amazon FBA, and a separate warehouse, keeping everything in sync gets harder with every new channel. 

3Dsellers solves the selling side. Sellers create listings with AI, publish them across marketplaces, sync inventory and prices, and manage every order from a single dashboard. The platform also automates Amazon FBA Multi-Channel Fulfillment, so orders from other marketplaces can be fulfilled from FBA inventory. AMZ Prep solves the physical side by getting that inventory prepped and into FBA correctly.

Who This Partnership Serves

eBay sellers expanding to Amazon, Walmart, Shopify, and other channels who need fulfillment that scales with them

Multichannel sellers using Amazon FBA inventory to fulfill orders from other marketplaces

Resellers and small teams that have outgrown self-fulfillment but want to keep listing and order management in one place

How It Works Together

Create and Publish Listings

Sellers use 3Dsellers’ AI listing tools to generate titles, descriptions, and item specifics from a photo, URL, or product identifier. Listings are then cross-listed to additional marketplaces, with inventory and prices kept in sync.

AMZ Prep Prepares the Inventory

AMZ Prep receives inventory, handles FBA prep and labeling, and creates inbound shipments to Amazon. Inventory can also be stored across AMZ Prep’s fulfillment centers for DTC and marketplace orders.

Orders Flow Into One Dashboard

Orders from every connected channel appear in 3Dsellers’ order manager. With FBA/MCF automation turned on, orders from non-Amazon marketplaces can be fulfilled from the FBA inventory AMZ Prep prepped and shipped.

Support and Scale

3Dsellers’ helpdesk gives support teams order details, tracking, and history inside each buyer message. As sellers add channels and SKUs, AMZ Prep provides the fulfillment capacity to keep up.
