Product Configuration

Setting Product-Specific Tax Codes

Each product can be assigned a specific tax code that will be used for Zamp tax calculations:

1. Navigate to Catalog > Products
2. Edit a product
3. In the General section, locate the "Tax Provider Tax Code" field
4. Enter the appropriate Zamp tax code
   • If left empty, the default tax code will be used (R_TPP )

Managing Tax Codes for Different Product Types

Simple Products

• Tax codes are set directly on the product
