What are House Accounts used for?

House Accounts are simply placeholders for transactions. These can be for multiple purposes, which is why the options are fairly generic, but can be also linked to Events. If you want to track a number of attendees, you may be better off creating events using the Events feature within Hop. If, however, you are looking to keep track of overall costs for an event or need to transfer some transactions from a reservation to a temporary "pot" then this is a good example of how a House Account can be useful.
