An individual or company who can fulfil products. E.g. for physical goods, somebody with a warehouse and means of delivery. Creating one or more instances of the Partner model is a required step in setting up an Oscar deployment. Many Oscar deployments will only have one fulfillment partner.

Usually that will be the headquarters or similar. This is a rudimentary implementation that raises an error if there's more than one address.
