How the setup fits together

A fee type defines what a charge means: its label, fixed or percentage calculation, tax behavior and display order. A product assignment then connects that reusable definition to a product, website and amount.

For example, one Environmental Handling Fee can be assigned at €4.90 to a bag and €12.50 to a piece of workshop equipment. Both products keep the same customer-facing meaning and tax defaults, while their amounts remain independent.

Manage fee types under Catalog > Product Fee Types and assignments in the Product Fees section of each product. Direct database changes are neither required nor supported.

The snapshot keeps completed sales documents independent from later changes to a fee type or product assignment.
