# Overview

eBay is the world's largest online marketplace. IDC connects your eBay account to NetSuite so you can manage orders, inventory, and payouts without manual data entry—orders flow into NetSuite automatically, shipments update eBay in real time, and settlement reports appear in your Settlements page.

## What it syncs

| Item listings    | NetSuite → eBay | Creates and updates eBay inventory items and publishes offers                       |
| Stock levels     | NetSuite → eBay | Syncs inventory quantities to eBay so listings show accurate availability           |

## How it works

IDC pulls orders, returns, and payouts from eBay on a schedule you set (typically every hour). When a new order arrives, IDC creates a NetSuite Sales Order with all details — customer, line items, shipping cost, tax, and any deposits. When you ship in NetSuite, IDC sends the tracking number back to eBay automatically.

For inventory, IDC reads stock levels from NetSuite and pushes them to eBay whenever stock changes. This keeps your listings accurate and prevents overselling. When the payout arrives from eBay, IDC imports it into your Settlements page so your finance team can reconcile it.
