Documents in Brix go through a life cycle during which their status changes. The status shows how far a document has progressed and determines what can still be done with it.
The most common flow is Draft > Approved, and if needed Voided:
Specialised documents can have more statuses. A job card, for example, goes through Draft > Open > Completed > Invoiced, and can also be Cancelled and Concluded.
The statuses of each form and their meaning are described on that form's help page, in the Statuses section.
