General Concept

Within Procurement Buyers and Sellers need to establish a business relationship in order to being able to do business with each other. In order to do so they need to establish a Contract. Without a confirmed Contract consumers will not be able to see and browse a supplier's catalog or to place an order.

In order to establish one, the Consumer needs to request a Contract via a ContractRequest which then needs to be accepted by the Supplier.

Consumers - How to handle contract requests

Consumers can requested a contract the Procurement web interface. Once the supplier accepted the request a procurement_consumer.new_contract will be fired and the consumer will be able to browse the catalog and place orders.
