Can MerchantSpring track performance by ASIN instead of SKU?

Yes. MerchantSpring supports product performance analysis using both ASIN (Amazon Standard Identification Number) and SKU (Stock Keeping Unit) data. This flexibility allows users to analyse product performance at different levels depending on how their catalog is structured.

Understanding the difference between ASINs and SKUs is important when interpreting reports.

ASIN vs SKU Explained

ASIN

An ASIN is a unique product identifier assigned by Amazon. Multiple sellers may sell the same ASIN if they list the same product.

ASIN-level reporting helps answer questions such as:

• How a product performs across listings
• Marketplace demand for a specific product
• Advertising performance at the product level

SKU

A SKU is a seller-defined identifier used to manage inventory within a seller’s catalog.

A single ASIN may have multiple SKUs if the seller:

• Uses different fulfillment methods
• Sells through multiple warehouses
• Creates variations of the same product listing

SKU-level reporting provides operational insights such as inventory and listing performance.

How MerchantSpring Uses ASIN Data

MerchantSpring maps SKUs to their associated ASINs when retrieving product data from Amazon. This allows the platform to generate reports that group performance metrics by ASIN.

ASIN-level analysis can be useful for:

• Understanding product demand
• Reviewing advertising performance
• Identifying top-performing listings

Steps to Analyse Products by ASIN

1. Navigate to Reports → Products
2. Select the relevant product performance report
3. Adjust the report view or grouping to ASIN
4. Apply filters or date ranges as needed

This will display aggregated performance metrics across all SKUs associated with the ASIN.

Notes: 

• Some reports default to SKU-level reporting.
• Products with multiple SKUs may show different performance when aggregated by ASIN.
• ASIN-level reporting is useful for understanding overall product demand across listings.
