Unified Product Structure
A unified product is the central entity created after matching products across different channels.
It represents a single product identity inside EVA by linking Amazon and Shopify data under one structure.
The Big Picture
A unified product is not a new product.It is a structured connection between existing products from different channels.
EVA Product ID
Each unified product is assigned an internal EVA Product ID.
This ID:
- uniquely identifies the unified product inside EVA
- acts as the reference point for all operations
- connects all linked channel data under one entity
The EVA Product ID does not replace ASIN or SKU, but sits above them as a unifying identifier.
Linked ASINs
A unified product can include one or more Amazon ASINs.
These ASINs:
- represent the Amazon listings linked to the product
- may include multiple variations or related listings
- remain unchanged in the Amazon Catalog
Linking ASINs allows EVA to associate Amazon data with the unified product.
Linked Shopify Variants
A unified product can also include one or more Shopify variants.
These variants:
- represent Shopify product variations
- include variant-level details such as SKU and price
- remain unchanged in the Shopify Catalog
Multiple variants can be linked to the same unified product when they represent the same item.
The Structure
A unified product follows this structure:
- one EVA Product ID
→ linked to one or more Amazon ASINs
→ linked to one or more Shopify variants
This creates a many-to-one relationship between channel products and the unified entity.
The Logic
EVA builds unified products only after a match is confirmed.
The system:
- keeps Amazon and Shopify data separate
- creates a unified product as a linking layer
- assigns an EVA Product ID
- connects all linked items under that ID
This ensures that all relationships are intentional and traceable.
Why This Matters
Without a unified structure:
- products would remain disconnected across channels
- performance data would be fragmented
- actions could not be applied consistently
With unified products:
- all related data is grouped under one entity
- cross-channel analysis becomes possible
- workflows become more consistent
Key Value Pillars
Centralized product identity
All channel data is connected under one unified product.
Flexible structure
Supports multiple ASINs and variants within the same product.
Consistent operations
Actions can be applied at the unified product level.
Pro Insight
A unified product can represent more than a simple one-to-one match.
It can also represent grouped relationships such as multiple variants or listings that belong to the same logical product.
