Cost Management System Overview
The Cost Management system allows you to define and manage product costs inside EVA, enabling accurate profitability analysis across your catalog.
It supports different levels of cost definition and allows cost data to be applied consistently across marketplaces.
The Big Picture
Cost is not stored in Amazon or Shopify in a usable way for profitability.EVA introduces a structured cost layer that allows you to define and manage product costs centrally.
ASIN-Level vs SKU-Level Cost
EVA allows cost to be defined at different levels depending on how products are structured.
ASIN-Level Cost
ASIN-level cost applies a single cost value to an entire Amazon listing.
This means:
- all units under the same ASIN share the same cost
- useful for products without variation in cost
- simplifies cost management for standard products
SKU-Level Cost
SKU-level cost allows cost to be defined for individual SKUs.
This means:
- different SKUs can have different cost values
- useful for products with variations such as size or packaging
- provides more granular cost control
This is especially relevant when SKU reflects real differences in cost structure.
Marketplace-Wide Cost Management
EVA allows cost values to be applied across marketplaces.
This means:
- the same product can maintain consistent cost definitions
- cost does not need to be re-entered for each marketplace
- global product strategies can be applied more easily
This is particularly useful for sellers operating in multiple regions.
The Logic
Cost data in EVA is:
- defined internally by the user
- independent from channel data
- linked to products via identifiers such as ASIN or SKU
The system:
- assigns cost to a product identifier
- stores cost as part of the EVA data layer
- uses cost for profitability calculations
This ensures cost remains flexible and fully controlled.
Why This Matters
Without a cost management system:
- profitability cannot be calculated accurately
- product decisions would rely only on revenue
With this system:
- cost becomes a core input for decision-making
- profit and margin analysis becomes reliable
- pricing and advertising strategies improve
Key Value Pillars
Flexible cost definition
Supports both ASIN-level and SKU-level cost structures.
Centralized cost control
Cost is managed in one place across the catalog.
Scalable management
Supports multi-marketplace operations without duplication.
Pro Insight
Use SKU-level cost when product variations have different production or logistics costs, as this improves the accuracy of profit calculations.
