Thanks to YITH WooCommerce Request a Quote, you can offer users the chance to ask for a quote for one or more products in your shop. Once the request is received, you can process your offer and send it via email. Users can accept the offer and will be automatically redirected to the cart where they will find the exact agreed price.
This plugin was designed to interact with YITH Desktop Notifications: among all the notifications you can enable, you will also find the chance to enable desktop notifications for each quote request received on your store or when a quote request of yours gains one of the followers statuses:
After installing and activating both plugins, you can set notifications for quotes by selecting A quote is placed in the Notification type option.
