A standard feature on the out of the box products I work with, it would be good to be able to send a link to a basket for the customer to complete the checkout process, and make payment.
This is standard on Shopify, Bigcommerce and Magento, Wordpress and Prestashop via plugin.
This has a commercial value in that valuable time can be saved responding to quote requests, and to product info requests with highly converting direct basket links. There is plenty of evidence out there to show a signifcant uplift in conversion when a link is enclosed with a response to a product query such as compatibility.
