The request quote plugins we added support for are based on WooCommerce. That works different than the ‘basic’ form quote options, since these plugins use the WooCommerce cart section instead of regular forms
Hello,
We have added support for “Request a Quote for WooCommerce” plugin by Addify
And also “YITH Request a Quote for WooCommerce”
Hope this helps!
