===Invoice Number===
To assign a unique consecutive invoice number open the booking and click on "Assign Invoice Number" in the "Invoice" tab of the booking. Invoice numbers are generated per account or sub account. If you have multiple properties or a group of properties and need invoice numbers for each property you can use [[:Category:Sub_Account|sub accounts]]. The default number is 1. A different "Next Invoice Number" can be set in SETTINGS->ACCOUNT->PREFERENCES.
