To add the quote to vendor products within the Webkul’s marketplace, the web store owner should have installed the Marketplace Quote System for Magento 2 add-on.  Using this add-on with the Magento 2 Marketplace module will allow the vendors to easily add quote to their products and manage the same on their own end. Even the customers can communicate with the respective sellers for their queries.

Vendor will navigate to his add product page and set the quote status  and the minimum quote quantity for the respective product being created. After this just save the product and you are done adding the quote to the product.
