Charge Me Later, Wholesale app

Works great, we always wanted to offer our B2B customers an option to charge on account on our website. This is a vers effective and cheap way of doing it (no need to develop intergation between shopify and the ERP).
When the customer calls us for the first time, we just need to add the tags to their customer account in shopify, they refresh their cart and boom, they can complete the order without paying. We were even able to put some automatic discounts based on the tags (i.e. 15%).
