Description

The Checkout Add-Ons addon inserts custom fields on the checkout page in WooCommerce, allowing you to charge extra fees, offer paid upgrades (gift wrapping, express shipping, engraving), and collect additional information before the order is completed. Each field can be configured as text, selection, checkbox, or multiline area, with its own display rules, fixed or percentage-based cost, and required status for those who sell physical or digital products that require additional options at checkout.
