The Problem

Most multi-channel tools make integration painful.

If you've tried other multi-channel tools, you already know the pattern. Long onboarding. Mapping wizards. CSV templates. Required sales calls.

📋

Migration wizards that take days

You're asked to map every SKU to a master template, fill in CSV exports, then re-import them once a specialist reviews your file. By day three, you're still not synced.

📞

Mandatory sales calls before you can test

Most enterprise multi-channel platforms gate any access behind a 45-minute demo call. You can't test on your own products, and you can't compare without first handing over your contact info.

🧩

Hours spent matching the same product across platforms

The same product lives under different titles, different categories, and different IDs on every marketplace. Without a way to link them, you're left manually pairing them one by one before you can even start managing prices or inventory.

The Master Product concept

One product, many listings, one source of truth.

The same item rarely looks the same across marketplaces. Titles, categories, and variant labels all drift. A Master Product ties those listings back to a single record so the system knows they're the same item. Master Variants do the same for size, color, and other options, so an "S" on Shopify and a "Small" on Shopify point to one variant.

  • ✓
    One Master Product per item in your catalog. Different title on Shopify, different images on Amazon, different description on Shopify? None of that matters as long as the SKU matches. Every listing ties back to the same Master Product.
  • ✓
    Master Variants handle the naming mismatch problem. Each platform tends to label sizes and colors its own way. Master Variants quietly map "S," "SM," and "Small" to the same record so you don't have to think about it again.
  • ✓
    See every platform side by side. Pull up one product and see its price, status, and inventory across every connected platform in a single row. Spot stale prices, silent stockouts, or missing listings at a glance, and manage status, pricing, and margins from one place.

How linking happens

Two ways to connect listings under a Master Product.

Every time you connect a new platform, the system scans the listings it just imported and compares their SKUs against products you've already connected from other platforms. Matches get linked automatically. When a listing has variants, each variant gets the same treatment so the platform-level variations roll up to the right Master Variant.

1
Automatic linking via SKU

Same SKU on two platforms? Linked instantly.

This is the path that takes zero work from you. If a listing on Shopify and a listing on Amazon share the same SKU, the system recognizes them as the same product and links both under one Master Product the moment the import finishes.

What it expects: SKUs are unique inside any given platform, and the same item uses the same SKU everywhere you sell it.
2
Manual linking

SKUs missing or out of sync? You make the call.

Sometimes the SKUs don't line up. A listing is missing one, the same item uses different SKUs across platforms, or a single platform has the same SKU on two different products. When that happens, you decide which listings belong together and pair them under one Master Product (and Master Variant, if there are variants).

Where to do this: Head to Link Products in the left sidebar any time after you've finished connecting platforms.
How it works

Connect, configure import, and auto-link in a few minutes.

The process is the same on every supported marketplace. Connect, choose what to import, and start the import. LinkSyncSell handles the linking from there.

  • ✓
    Connect your platform in a few clicks. Each marketplace uses its own standard sign-in flow inside LinkSyncSell. No CSV uploads, no developer required.
  • ✓
    Import All or Select Products. Select what products to import into our app, either choose the full catalog or apply filters (SKU, Vendor, Category, Collection, Product ID, or Type) to bring in just a subset.
  • ✓
    Begin import and let auto-linking run. Each imported listing is matched by SKU. Found a match? Linked to the existing Master Product. No match? You can manually link it to an existing Master Product or assign it to a new one.

1
Connect your platform

Click the platform card, sign into your seller account, and approve the integration. Done in a few clicks.

2
Import All or Select Products

Choose All Products, or use Select Products (Apply filters) to import only a subset.

3
Begin import & auto-link

Each listing is matched by SKU. Matches link to the existing Master Product. Unmatched listings let you link manually or assign a new Master Product.

✨ Same SKU on another platform? Auto-linked to the same Master Product.
Selective imports & auto-link logic

Import only what you want. Link it automatically.

If you don't want to bring in your entire catalog, choose Select Products (Apply filters) and narrow the import down using product filters. After the import runs, each listing is matched by SKU to your existing Master Products. Anything without a match shows up in Link Products where you choose how to handle it.

  • ✓
    Filter by platform-specific product filters. Enter multiple values separated by commas. Useful for partial migrations, brand-by-brand rollouts, or testing on a small subset first.
  • ✓
    SKU match → linked to existing Master Product. Any platform listing whose SKU already exists in your catalog is attached to that Master Product instantly. Per-platform listing details (titles, descriptions, images) stay native to each marketplace.
  • ✓
    No SKU match → you decide. Unmatched listings stay visible in Link Products. From there you can manually link the listing to an existing Master Product, or assign it to a new one. Either way nothing is silently misfiled.
  • ✓
    Review and reassign anytime. The Master Product page shows every linked listing per platform. Reassign or merge Master Products from the Link Products screen if SKU schemes don't match across platforms.

Real Use Cases

When connection complexity stops being your problem.

These are the moments where most multi-channel tools fail and LinkSyncSell quietly works.

New Channel
🚀

You just added Amazon to your existing channels.

You've been on Shopify for two years and recently went live on Amazon. Both stores carry the same SKUs, but managing pricing and inventory across two dashboards is a pain. Connect Amazon to LinkSyncSell and SKU matching automatically links every Amazon listing to its Shopify counterpart under one Master Product.

Connect Amazon → Choose import scope → SKUs auto-link to existing Shopify products → One Master Product view across both.
Selective Import
🎯

You only want to import certain products from certain vendors.

Maybe you have ten brands on Shopify but only two are ready for multi-channel. Use Select Products (Apply filters) when configuring the import, pick Vendor, and enter just the brand names you want. Only those listings are imported.

Continue Setup → Select Products → Apply filter: Vendor → Enter brand names → Begin import → Only those listings come in.
Mismatched SKUs
🧩

The same product has different SKUs on every platform.

Your Amazon listing uses "COT-001," Shopify says "cotton-001," and Shopify has no SKU at all. LinkSyncSell auto-links anything with a matching SKU. Anything else stays in Link Products, where you can manually attach it to an existing Master Product or assign it to a new one.

Import products → Auto-link by SKU runs → Unmatched listings appear in Link Products → Manually link to existing Master Product or assign a new one.
Wholesale + DTC
🏪

You sell DTC on Shopify and wholesale on Faire.

Your Shopify catalog and your Faire catalog share the same products, but at very different price points. Connect both, let SKU matching link the listings under one Master Product, then set per-platform pricing so retail and wholesale stay separate while everything else stays in sync.

Connect Shopify + Faire → SKUs auto-link → Set per-platform pricing → Wholesale and DTC managed from one Master Product.
FAQ

Frequently asked questions

What is a Master Product?
A Master Product is LinkSyncSell's unified record for a single item in your catalog. Every platform listing for that item (Shopify product, Amazon ASIN, Shopify listing, TikTok Shop SKU, Faire SKU) attaches to the same Master Product. You manage one Master Product and the system handles per-platform mapping for prices, inventory, status, and listing details.
Can I import only some of my products instead of everything?
Yes. You can select to import All Products or Select Products via product filter. You can filter by SKU, Product ID, Category ID, Collection ID, Vendor, Listing Status and more. You can run additional imports later for more products.
How does auto-linking work?
During import, LinkSyncSell matches each imported listing's SKU against your existing Master Products. If we find a match, the listing is attached to that Master Product. If no match is found, the listing stays visible in Link Products so you can choose what to do with it: link it to an existing Master Product manually, or assign it to a new one. You decide; nothing is silently misfiled.
What if a product has no SKU, or different SKUs on different platforms?
Each listing still gets attached to a Master Product, either an existing one if any SKU matches, or a brand-new one if not. From the Link Products screen you can later merge separate Master Products together or reassign listings to a different Master Product to consolidate items with mismatched SKUs.
How long does the initial import take after connecting?
It depends on the size of the catalog you're importing. Smaller catalogs finish quickly, while larger ones take more time and continue in the background. You can keep using the dashboard while the import runs.
Can I connect multiple Shopify or Shopify accounts?
Each LinkSyncSell company connects one account per platform (one Shopify, one Shopify, one Amazon, and so on). If you operate multiple brands or stores, you can create additional companies inside LinkSyncSell and switch between them from the company switcher. Each company manages its own set of platform connections, products, and orders independently.
