Sales embrace all sales of inventory as well as income from facility hire. A Sale however excludes 'Unconfirmed Reservations' which do not become a sale until entered as such via the POS Window.
A 'sale' may not actually involve the exchange of money. For example, you may allow a facility hire to be recorded without accepting any payment at all. [Do not confuse this with Unconfirmed Reservations which are not even treated as a sale until you record them as such].
