Import your existing channel listings into the 3Dsellers Catalog to centralize product data, avoid duplicates, and keep inventory and pricing in sync across channels.

This guide explains:

Before You Start

To import listings into the Catalog, the Catalog feature must be enabled for the channel integration.

If Catalog is disabled, the Import to Catalog option will not be available.

🔧 Enable Catalog in Integration Settings

  1. Go to Settings → Integrations

  2. Open your channel integration (e.g. eBay, Amazon)

  3. Locate the Multichannel Catalog column

  4. Make sure the toggle is enabled

🔧 Catalog & Sync Settings (Important Before Importing)

Before importing listings, it’s important to understand how Catalog sync settings work.
These settings control how price and inventory move between your Catalog and the marketplace after import.

Where to Find Catalog Sync Settings

  1. Go to Settings → Integrations

  2. Open eBay Accounts (or another channel)

  3. Click Settings next to the specific account or region

  4. Review the Catalog & Sync settings panel

💲 Price Sync Behavior

These options control how price changes flow between the Catalog and the channel.

Update product prices on the channel

  • Price changes made in the Catalog will update live listings

  • Mapping Templates and pricing Rules are applied

Use this if:

  • The Catalog is your source of truth

  • You use pricing rules (markup, rounding, .99 endings, currency conversion)

Don’t update product prices on the channel

  • Catalog price changes will not affect live listings

Use this if:

  • Prices are managed directly on the marketplace

  • You only want the Catalog for reference or reporting

📌 Important: Importing listings always updates the Catalog. These settings control whether changes flow back to the channel.

📦 Inventory Sync from Catalog Changes

These options control how quantity changes in 3Dsellers affect live listings.

Update product quantity on the channel

  • Inventory updates from:

    • CSV uploads

    • Bulk actions

    • Manual edits

    • Received orders
      will update the marketplace listing quantity

Update quantity for unlinked listings

  • Applies inventory updates even if listings are not fully linked yet

Recommended if:

  • You manage inventory centrally in 3Dsellers

  • You want to avoid overselling

🛒 Inventory Sync from Received Orders

These settings define what happens after an order is received from the channel.

Update product quantity in 3Dsellers

  • When an order is imported, Catalog inventory is reduced automatically

Recommended for:

  • Accurate stock tracking

  • Multi-channel inventory control

⚠️ How These Settings Affect Imports

  • Importing listings:

    • Always creates or updates Catalog products

  • Sync settings control:

    • Whether Catalog changes update live listings

  • If sync is disabled:

    • Imports still work

    • Listings will not update automatically afterward

✅ Recommended Setup (Most Sellers)

For a smooth import + sync workflow:

  • Enable Multichannel Catalog

  • Enable Price updates on the channel

  • Enable Inventory updates on the channel

  • Enable Update quantity from received orders

This ensures:

  • Clean imports

🧠 Import Popup: Advanced Settings Explained

When importing from the Listing Tool or Catalog, you’ll see the Import Settings popup.

1. Choose the Selling Channel

Select which connected channel to import from
(e.g. eBay US, eBay UK, Amazon).

This controls where listings are pulled from.

2. 🔗 Match & Merge Imported Products

Controls how duplicates are detected and merged.

Default matching

  • 3Dsellers field: SKU

  • Channel field: SKU

Listings with the same SKU merge into one Catalog product.

➕ Add Another Field (Optional)

Strengthen matching using an additional identifier:

  • SKU

  • Title

  • UPC

  • EAN

  • ASIN

  • MPN

  • ISBN

Examples:

  • SKU + UPC → safest matching

  • SKU + Title → when SKUs vary slightly

  • EAN → common for EU catalogs

3. Import Behavior Options

These options control how data is handled during import.

Override existing product with newly imported data

  • Imported data replaces existing Catalog values

Use when:

  • Channel listings are the source of truth

Don’t create new products

  • Only updates existing Catalog products

  • Skips unmatched listings

Use when:

  • You want to refresh existing items only

Import only products with available quantity

  • Skips out-of-stock listings

Import new products inventory to a warehouse

  • Assigns stock for new items to a selected warehouse

Add tags to imported products

  • Automatically tags imported items for organization

Examples:

  • Imported from eBay

  • UK Channel

  • Clearance

Match SKU by pattern

Helps match SKUs with prefixes or suffixes.

Example:

  • Channel SKU: UK-12345

  • Catalog SKU: 12345

🔄 After Import: What Happens Next

After import completes:

  • Listings become Catalog products

  • Images, descriptions, price, and inventory are pulled in

  • Matching logic merges duplicates listings with the same identifier

  • New products are created unless blocked by settings

🔁 Want Catalog Changes to Update Live Listings?

Imports affect the Catalog only.

To push updates back to the channel:

  1. Go to Products Catalog → Products

  2. Select items

  3. Click Bulk Actions → Bulk Revise Listings

✅ Best Practices

  • Enable Catalog before importing

  • Use SKU + UPC/EAN when possible

  • Use Override carefully

  • Add tags like Imported from Channel

  • Import a small batch first to validate behavior
