WooCommerce Custom Currencies is a WordPress plugin designed to enhance the shopping experience by allowing users to add their own currencies to their WooCommerce store. As a beta version, it offers essential features such as defining conversion rates for custom currencies, facilitating transactions through the PayPal gateway, which is officially supported for conversions. This capability is particularly useful for merchants dealing with currencies not supported by PayPal, enabling them to convert to widely accepted currencies like USD or GBP for processing payments.

The plugin is compatible with WordPress version 4.0 and WooCommerce version 2.2, making it suitable for users operating on these platforms. However, it is important to note that refund functionality is not yet available in this version. Despite its limitations, WooCommerce Custom Currencies provides a valuable tool for enhancing e-commerce flexibility and catering to a diverse customer base.
