WPC Order Tip for WooCommerce is a simple-to-use yet powerful plugin, which adds multiple sets of extra amounts that customers can choose to add to their order value as a tip or donation to the seller or stated donees. Store owners can offer multiple ways for buyers to show their generosity via order tips for the shop, delivery man or contributions and donations to local charity funds, shelters, organizations, etc.
Users can set up multiple types of tip and donation options with predefined values (fixed amount or a percentage of the subtotal value) or custom amount with rules for min/max/step/default value (“Other” option). Customers can easily click on any option and the extra amount will be added to the subtotal automatically or subtly decline by choosing the “No, thanks” option.
