How can I create custom baskets for customers to checkout?

[KieranC]

Hi all, 

My business designs systems for customers that is made up of various products and components. 

Once they approve these systems, they purchase the products through our Shopify site. 

Currently, we have to send them a list of all the products and they have to purchase them but I would love the ability to 'Build a basket' and just send them a link that allows them to checkout. 

I appreciate the obvious difficulties with regards to cookies etc. but does anyone have any suggestions as to how I would do this?

Thanks in advance.

You can do this in the back end of shopify, create a draft order and send them a link to pay the invoice.
