# Invoices In this menu you can view and edit your customers' invoices or enter and send invoices. An invoice does not necessarily have to be related to a plan or a module, which is why this tool can also be used for other purposes.

## Invoice states The following states for invoices exist in saaster:

	Description
Draft	In draft mode, the invoice can still be modified. The invoice is not displayed to the customer while still in draft state
