Square has a lot of the functionality in place to support companies having a B2B site. One of the remaining functions is the ability to allow businesses to charge against a house account online. This would allow a seller to provide access to staff of a business customer to place orders for product, but invoice the accounting department. Ideally the way this would work would be after a customer signs into the Square Online account and adds items to their cart in the Checkout Payment screen the system should present the house account payment option if the user has a house account. The system should also have the functionality to provide errors if the order exceeds the limit of the house account where it tells the user what the limit is to edit the order to remain under the limit.
