If you sell online, you know how frustrating it can be to keep track of prices, stock, and promotions across multiple e-commerce platforms like Shopee, Lazada, and TikTok Shop. You change a price on one store, but forget to update it elsewhere. A customer places an order, but your stock isn’t updated in time, leading to cancellations. Sound familiar?

That’s why BigSeller introduced Master Product Management, to help sellers organise their products, sync pricing, and manage inventory in one place. At the core of this system are Merchant SKUs and Store SKUs, which work together to keep your business running smoothly. But what do these terms mean, and how do they help with SKU mapping? Let’s break it down.

Understanding Merchant SKU and Store SKU

1. What is a Merchant SKU?

A Merchant SKU is a unique product code used inside the warehouse to track and manage stock. It helps sellers organise inventory before products are listed in online stores.

• Think of it like a product’s ID number in your warehouse system.

• It ensures that the right product is shipped and that stock levels are correct.

• Even if the same product is sold on different platforms (Shopee, Lazada, TikTok Shop), it has one Merchant SKU in the warehouse.

2. What is a Store SKU?

A Store SKU is the product code given by each e-commerce platform (Shopee, Lazada, TikTok Shop) to track the product in their system.

For example, if you sell a wireless speaker:

• On Shopee, it might be called "Wireless Speaker 5.0 - High Bass Sound" with Store SKU SPK-SH-001.

• On Lazada, it might be "Bluetooth Speaker with Deep Bass" with Store SKU SPK-LZ-001.

• On TikTok Shop, it might be "Portable Speaker for Travel - Loud & Clear Sound" with Store SKU SPK-TT-001.

Even though these listings have different Store SKUs, they all belong to the same Merchant SKU in your system.
 

• The Merchant SKU (BT-SPK-001) is the warehouse code for a wireless Bluetooth speaker. This SKU helps track stock before it is listed for sale.

• Each online platform (Shopee, Lazada, TikTok Shop) assigns a different Store SKU, but they are all connected to the same Merchant SKU in the warehouse.

What is Master Product Management and How Does It Work?

BigSeller’s Master Product Management is a feature that links all Store SKUs under a single Merchant SKU, making it easier to update prices, stock, and promotions across different platforms.
 

How to Set Up Master Product Management

1. Create a Merchant SKU: Start by assigning a unique Merchant SKU to each product in your warehouse. This helps you keep track of stock before selling it online.

2. Map Store SKUs to the Merchant SKU: Once your warehouse inventory is set, connect the Store SKUs from Shopee, Lazada, and TikTok Shop to the corresponding Merchant SKU.

3. Sync product details automatically: Any updates (price changes, stock adjustments, promotions) made to the Merchant SKU will instantly update all linked Store SKUs.

This setup saves time and reduces the risk of errors, so you don’t have to update each store manually.
 

Key Benefits of Master Product Management

1. Prevent Overselling & Stock Issues

Nothing frustrates customers more than ordering a product only to find out it’s out of stock. SKU mapping helps you:

• Sync inventory levels across all platforms in real time.

• Avoid overselling by ensuring stock updates happen instantly when an order is placed.

• Reduce order cancellations, improving your store’s credibility and customer satisfaction.
   

2. Bulk Price Updates Across Platforms

Instead of changing prices manually on each store, SKU mapping lets you:

• Update prices in bulk across all your stores in just a few clicks.

• Adjust promotional prices automatically without needing to edit each listing manually.

• Maintain competitive pricing based on real-time exchange rates (for cross-border sellers).
   

3. Effortless Promotion Management

Running sales and promotions on multiple platforms? Master Product Management makes it easier by allowing you to:

• Apply discounts and flash deals in one place and sync them across stores.

• Ensure promotions reflect correctly on each platform without manual adjustments.

• Track performance of sales campaigns with accurate, centralised data.
   

4. Better Sales Insights & Reporting

With all data in one place, you can:

• Monitor sales performance per product across different platforms.

• Analyse pricing trends and make data-driven decisions.

• Identify best-selling products and adjust inventory strategies accordingly.
   

Selling on different platforms can be tricky, but Master Product Management makes it easy. By linking your products under one system, you can update prices, stock, and promotions without extra effort. No more worrying about overselling or manual updates as everything stays in sync automatically.
