Getting Started

3. Click Activate to enable the plugin.
4. Configure Attributes on a Variable Product:
5. Navigate to Products > All Products and edit an existing Variable Product (or create a new one).
6. Under the Attributes tab in the Product Data panel, assign your desired global or custom attributes (e.g., Color, Size, Material).
7. Save and update the product before proceeding to the next step.
8. Set Attribute Fees:
9. Click the new Attribute Fees tab in the Product Data panel.
10. For each attribute option, enter a fee value and select the appropriate Fee Type:
11. Flat: Adds a fixed currency amount (e.g. +$10.00).
12. Percentage: Adds a percentage fee calculated from the base variation price (e.g. +15%).
13. Compound Percentage: Calculates the percentage fee based on the running price including prior fees.
